The Latest Research Resisted and Assisted Training, Warm Up Protocols and Strength Programming
The latest edition of the IAAFâ€™s New Studies in Athletics technical journal has been released. Among many excellent studies included in this edition is an article written by South Australian coach, Dylan Hicks. The article explores the effectiveness of resisted sprint training and assisted sprint training and we are delighted to include a summary of his research.
Resisted and Assisted Sprint Training:
Determining the Transfer to Maximal Sprinting
Abstract Resisted sprint training (RST) and assisted sprint training (AST) are methods used to overload the neuromuscular and physiological systems with the aim of causing adaptations that transfer to ‘free’ maximal sprinting (MS). This review of more than 50 publications summarises teh effects of RST and AST with the aim of assisting coaches to understand their application. RST has been shown to promote kinematic changes that emphasise propulsive force application in MS. RST using pulled sled loads of 10-30% bdoy mass also appears to be effective in improving acceleration abilities while loads greater than 30% of body mass appear to disrupt acceleration mechanics. AST using a horizontal towing mechanism over distances between 20-60m enhances acute maximal horizontal velocity. Across most reviewed studies, AST with towing or downhill
“Resisted and assisted sprint training interventions appear to have the greatest transfer to maximal sprinting when performed bi-weekly across one or more training cycles of four to eight weeks”
running increases stride length while ground contact time decreases. Stride frequency, however, decreases or remains unchanged. This suggests that AST may not provide any greater transfer than a standard maximal sprinting protocol, but due to the inconsistencies in the research it should be left to the practioner to determine whether AST is suitable. Full article available for New Studies in Athletics subscribers.
Contrast Training Hicks also suggests that the use of a combination of RST, AST and MS within the same session may be an effective strategy for enhancing motor patterrns and improving maximal speed. There is some evidence to suggest that the most effective composition of contrast training is to conduct the RST and AST first, followed by free sprinting (Wagganer, Williams &

“This might be a reminder that static stretching isn’t the devil it’s been made out to be” Tony Blazevich
No Effect of Muscle Stretching within a Full Dynamic Warm-up on Athletic Performance Tony Blazevich from Edith Cowan University, whose research on the aerobic capacity of children was featured in Athletics Coach - 2 / 2018, has now teamed up with a range of international sports researchers to investigate the effects of static and dynamic stretching routines on flexibility, sprinting and jumping performance. Their findings have recently been published by the American College of Sports Medicine and he has very kindly shared a summary of the key findings with Accredited Athletics Coaches.

“The primary finding was that 6 weeks of resistance training led to significant increases in maximal strength and fat-free mass. In addition, it seems that increased training frequency does not lead to additional strength improvements when volume and intensity are equated. High-frequency (6× per week) resistance training does not seem to offer additional strength and hypertrophy benefits over lower frequency (3× per week) when volume and intensity are equated. Coaches and practitioners can therefore expect similar increases in strength and lean body mass with both 3 and 6 weekly sessions.”
Training Volume, Not Frequency, Indicative of Maximal Strength Adaptations to Resistance Training In Athletics Coach - 2 / 2018, we shared a weekly training program used by sprints coach Glen Mills, which resulted in some coaches expressing surprise at the infrequency of his gym sessions. A recent study published in the Journal of Strength and Conditioning Research may offer an explanation of his rationale, with higherfrequency training resulting in no signficant improvements in stregnth or hypertrophy benefits comapred with lower frequency training when intensity is equated.

“The manipulation of training volume and intensity must be systematic, stimulating continued physical adaptions through progressive overload whilst guarding against maladaptive training outcomes such as non-functional overreaching and overuse injury through the integration of sufficient recovery”
Understanding the Relationship Between Coach and Athlete Perceptions of Training Intensity in Youth Sport A recent study published in the Journal of Strength and Conditioning Research has highlighted the prevelance of mismatches between the coach’s intended training session intensity and the perceived intensity by the athlete. Of the coaches and athletes studied by Scantlebury et al. (2018), coaches tended to overestimate the intensity of sessions designed to be ‘high intensity’ whereas they tended to underestimate the intensity of sessions intended to be ‘low intensity’. This mismatch between the intended intensity and actual intensity results in coaches prescribing ‘high intensity’ sessions that do not provide a sufficient training stimulus to achieve the desired adaptation and ‘low intensity’ sessions which resulted in excessive load on the athlete, hampering their recovery and predisposing the athlete to over-use injuries. The authors of the study suggest that coaches implement ongoing athlete surveys, asking the athletes to grade a sessions intensity between 1 and 5 to ensure that the coach’s intended training intensity is aligning with reality.

A Comparison of the Effects of Short-Term Plyometric and Resistance Training on LowerBody Muscular Performance The evidence examining the effectiveness of plyometric training for athletics coaches continues to build, and this latest study by Whitehead et al. (2018) helps coaches to understand the most effective training methods for a given performance parameter. The study tested 30 male athletes who were distributed to either a plyometric training program, a resistance training program or a control group who did not participate in any training. Training was twice per week over an eight week period. Pre- and post-intervention tests were performed on the participant’s 20m sprint time, standing long jump, vertical jump, 1RM back squat and agility test. After the training intervention, athletes in the plyometric training group significantly improved their vertical jump and 1RM back squat, with a “likely improvement” in their standing long jump performance. However, neither the plyometric training group nor the resistance training group improved their 20 metre sprint time, conflicting with previous studies that have shown both training interventions may improve an athlete’s speed. This may be explained by the frequency / intensity of training being inadequate or by the focus on ‘vertical plyometric’ activities, rather than activities that focus more on a horizontal generation of force. The authors conclude that “Plyometric training programs
“Like any other training component, plyometrics need to be considered within the context of the overall program.”
similar in duration and intensity to the one used in the current study should result in an improvement in body composition and vertical jump. Both plyometric and resistance training appear to result in improvements in lower-body muscular performance in untrained men. More specifically, there are equal increases in standing long jumping ability and maximal strength. What this

means is that decisions can be effectively made regarding time spent in an individual training mode based on the individual needs of the athlete, equipment, and facility limitations.”

The ‘Specific Adaptation to Imposed Demand’ or ‘Specificity’ principle suggests that strength gains
and this should determine how and what we train. To maximise the transfer between ‘weight room strength’ and the specific strength required for sprinting, coaches need to ensure that their chosen exercises best replicate the unique conditions of sprinting. This article will examine how the velocity, muscle group, muscle action, direction of force and joint angle of the muscles trained will effect the training outcomes and how these factors can be manipulated to maximise training outcomes for sprinting performance.

The Principle Training exercises that are performed at a high velocity will lead to proportionally greater gains in high velocity strength. For example, exercises that are performed at high speed such as hang snatches (click here for an example video) will theoretically lead to a proportionally

results showed that participants from the slow treatment group had proportionally greater strength gains at low velocity and those from the fast treatment group had proprotionally greater high velocity strength gains.
The velocity-specific nature of strength has since been supported by a of studies that have demonstrated it is true for single-joint exercises (Moss et al., 1997; Ingebrigtsen et al., 2009), multi-joint exercises (Mora-Custodio et al., 2016) and in trained (Aagaard et al., 1994) and untrained athletes (Moss et al., 1997).
Speed of Movement “It appears that the velocity of the movement...plays a key role in improving high-velocity performance capabilities and possible neural mechanisms of adaptation” E.F Coyle , 1981
The Sprinting Implication Sprinting is primarily a high velocity action, so strength training at high speeds should result in greater improvement of sprinting performance than training at lower speeds. A longitudinal study by Loturco et al. (2015) supported this hypothesis, demonstrating that a high velocity strength program resulted in proportionally a greater improvement in 5, 10 and 20 metre sprint times compared with a lower velocity training program.
Intent to produce force quickly. There is some evidence to suggest that the actual speed of the action is less important than the cognitive intention of the athlete. That is to say, there will be improvement in high velocity strength when the athlete intends to perform training at maximal velocity, regardless of the actual movement speed (Behm & Sale, 1993). See Balshaw et al. (2016) for an excellent explanation of the proposed neural factors
The Coaching Application The velocity that an execise is performed can be manipulated using the following methods: •
Reducing the weight of the training implement. There is some evidence to suggest that exercises conducted between 30 and 60 percent of the athlete’s 1RM are the most effective for improving high velocity strength and
involved in this. Young (2006) also advises that sprinters will also still benefit from a general non-specific resistance program and that a sprinter’s program should include more than exclusively high-velocity exercises. General resistance training is likely to aid injury prevention and facilitate the development of highvelocity strength.
improving sprinting performance (Young, 2006; Thomas et al., 2007; Mora-Custodio et al., 2016).
Muscle Group The Principle It is well understood that strength gains are specific to the groups of muscle that are being stressed. Athletes must incorporate a range different exercises to develop the range of muscles that contribute to sprinting performance (Gonyea

The following exercises have been recommended by strength and conditioning experts for sprinters looking to build strength in these muscle groups.

2002; Young, 2006; Beardsley & Contreras, 2014). Electromyographic analysis of the sprinting action has suggested that the hamstrings may have the greatest increase
in muscle activation as running speed increases, suggesting that they may be an important driver of running velocity (Kyrolainen et al., 2005).
Hip Flexors (esp. Psoas major, Rectus femoris) The size of an athleteâ€™s psoas major has been shown to be correlated to their sprinting ability (Copaver, Hertogh & Hue, 2013) and has been shown to be an important muscle for increase stride frequency during sprinting (Dorn et al., 2012). Evidence has shown that a hip flexion program can improve 10-yard and 40-yard sprinting times (Deane et al., 2005).
Knee Flexor (Hamstring group) The hamstrings are also an important muscle group for knee flexion, which is believed to contribute to sprinting performance (Mann & Hagy, 1980), especially during the late swing and early stance phase (Jonhagen et al., 1996).

Hip Extensors What about the Quadriceps? A recent study by Miyake et al. (2017) tested the difference in the cross-sectional area of the quadriceps between sprinters and non-sprinters. The results demonstrated that there was not a significant difference in the size of the quadriceps muscles between sprinters and non-sprinters, suggesting that the muscle group is not a signficant contributor to sprinting success. The researchers also found a lack of correlation between the size of an athleteâ€™s quadriceps and their reported personal best time over 100 metres. This finding was supported by Bex et al. (2016) who found that a greater hamstring:quadriceps ratio was correlated with faster sprinting performances. However, it should be noted that Handsfield et al.â€™s (2016) study found that the rectus femoris to be one of the proportionally largest muscles in elite sprinters compared with non-sprinters, suggesting that further research is required before we fully understood the importance of this muscle group for sprinters.

Load increased as subject withstands the forward fall longer. When managing to withstand the whole ROM for 12 reps, increase load by adding speed to the starting phase of the motion.
Strength and conditioning expert Chris Brearley recommends implementing two sessions of eccentric-specific exercises per week out of season (alternating between Nordic Hamstring Curls and Flywheel Leg Curls) and one session per week inseason.
de Hoyo et al. (2015) demonstrated that an eccentric-specific training program was an effective intervention for improving maximum running speed in junior football players in addition to assisting injury prevention. This has been supported by further studies that demonstrate that the development of eccentric strength using a plyometrics program has been effective for improving speed and acceleration (Rimmer & Sleivert 2000; Faigenbaum et al., 2007). The Nordic Hamstring Curl has been found to be a more effective exercise for developing eccentric hamstring strength than traditional hamstring curls (Mjolsnes et al., 2004).
Bret Contreras recommends that the Nordic Hamstring Curl be conducted with a resistance band that allows the athlete to control the movement throughout the full range of motion. When the majority of athletes attempt the motion you will notice that they lose control of the descent during the second half of the motion, whereas the resistance band will provide greater support as the athlete lowers themselves closer to the ground, ensuring that their muscles are active throughout the exercise.

There is also evidence to suggest that the inclusion of horizontal plyometrics can be effective for improving an
athleteâ€™s speed (Ozbar, Ates & Agopyan, 2004).
The best evidence for the effectiveness of exercises generating a horizontal force vector for improving sprinting performance was a comparative study between the hip thrust and front squat by Contreras et al. (2017). The study found a significantly

Conclusion By understanding the ways that strength is specific, we are able to design a strength program that results in a maximal improvement in performance. However, while this article explored some of the ways that strength is specific, it is by no means intended to be an exhaustive list of the way strength transfers to the unique requirements of sprinting. The challenge for you to take from this article is to think about the other unique strength requirements of sprinting and which exercises in the gym will transfer most effectively.
Note on Coaching Young Athletes “Even though laboratory research demonstrates that specificity training results in faster adaptation and leads to faster increments in performance, this does not mean that coaches and athletes have to incorporate specificity training from an early age. In this narrow approach to children’s sport, the only scope of training is achieving quick results irrespective of what may happen in the future of the young athlete...This is like trying to build a high-rise building on a poor foundation.” Tudor Bompa PhD

Marathon Training and Performance: Sub 3 Hours Written by Ben Green from Front Runner Level 4 Senior IAAF Coach Presenter
ince commencing personalised training programs in 2009, the Front Runner coaching team has been primarily focused on assisting both recreational and competitive runners competing in events ranging
from 800m to the Marathon, as well as Full and Half Ironman Triathlon. Over time, the tracking of data (through GPS and online training software) and personalised exercise prescription based on the runner’s individual goals and training history, has allowed for empirical data to be compiled from our ever-

As our database grows, we continue to observe certain trends in the data that help guide our coaching team towards more accurate and effective exercise prescription. As well as a strong scientific element to data tracking, working with a team of nine engaged coaches all with individual experiences and qualifications has enabled an excellent structure to develop hypotheses on further improving exercise prescription. With the popularity of the Marathon increasing in recent years, we have updated our initial data from 2016, focussing on those runners who have broken the magical 3 hour barrier. At the 2018 Melbourne Marathon, the 61st Front Runner
many athletes at a high recreational marathon standard, in combination with monitored training prescription, has allowed us to identify some strong data trends. We hope that awareness and knowledge of this data will continue to help our running community progress towards their individual goals, as well as educate fellow runners and coaches interested in enhancing performance in recreational marathon populations. Through ‘Training Peaks’ software, we analysed the data based on what we believe are two key principles for successful distance running and how they related to Marathon performance (goal time). 1. Anaerobic Threshold: Measured as their best 10k race time within 12 months of their best marathon 2. Volume: Peak 4 week mean volume within the final 3 months of their goal Marathon A 10km race is a practical estimate of the anaerobic threshold (the upper limit of how well the body can sustainably use oxygen for energy – see more here). The lower the 10km time, the higher the anaerobic threshold and the more effectively the runner can utilise oxygen for aerobic metabolism.
The peak mean volume the runners were able to sustain for four consecutive weeks in the lead up to their Marathon is a practical indication of their muscular endurance. As running is a weight-bearing activity, covering 42.2km’s requires significant muscular endurance. Four consecutive weeks were

Of the 61 Front Runner athletes to have officially broken 3h for the Marathon, objective data was available and collated from 38 of these athletes.The figure below plots the runner’s marathon and 10k pace against their weekly training volume. The two variables showed a moderate correlation, with pace increasing as weekly training volume increasing.

If the answer is NO then something has to change.
Obviously it does happen, but tends to be less prevalent and usually plays out in a more low key manner. Most coaches have great intuition. I suppose it’s part of the humanistic approach many have and their ability to read peoples thoughts and emotions. So when certain dynamics within the coach-athlete relationship start to change, intuition will then play it’s part in determining whether they may have a lasting or significant impact on the relationship. Or… might this just be a repositioning of how the relationship will continue into the future?

So what are the next steps? Well given we see communication as such an important part of what we do, how about a face to face catch up to chat about ‘stuff’. The intent of this catch up however must be quite clear – to clarify the expectations of both the athlete and coach. If it’s obvious from this catch up that those expectations are no longer in synch, then the time has come to make the big call.

Moving On Emotions can run high in any form of relationship change. It is critical that rash decisions not be made, things said that shouldn’t be said and respect on both sides maintained. Does the athlete have a transition plan? If not then you should play a role in setting this up. Dumping and running isn’t going to help either party so assist as required or engaged to make sure as smooth a transition as possible exists. Remember – you often know more about the athlete in the sporting context than they do themselves and the information you possess is important in any transition process. So although this is a topic rarely raised publicly, don’t be afraid to tackle it head on when you believe you need to. Calling time at the right time will definitely save a lot of heartache in the long run.

Top 5 Tips for Building a New Coach-Athlete Relationship Written by Rohan Short
ooner or later as your coaching experience grows â€“ you may be asked to take on a new athlete. But how do you go about building this new relationship and integrating the athlete into an existing squad?
It is completely normal for a new squad member to feel anxious about joining your athletics squad because they may not know exactly what to expect. Even the fear of placing your training gear in the right place or making sure you stay out of the way of other athletes is very real. As the coach you have only one first impression to make sure that you get a new squad member plugged in and excited about the decision to join your training environment. Making sure you start off on the right foot, not only ensures that your new training squad member keeps coming back â€“ but also helps to create positive word-of-mouth advertising around your program.

4. Prepare Ahead of Time To minimise any disruption when adding a new athlete into their first training session – the very least the coach can do is confirm ahead of time that the athlete knows where they need to be, by what time, what they need to bring and wear. It sounds so simple – but often these are the things that a new athlete is always the most anxious about. Ahead of time make sure your all your current athletes are aware that a new face will be joining the group. Upon arrival, introduce the new athlete to others you see around the training environment – including other training squads that may use shared spaces at the same time. It may be appropriate to give another athlete the responsibility to ‘buddy up’ with the new squad member – but certainly the need for this is all about helping to facilitate social connections. Above all the most important thing is to make sure that you keep things fun. Whilst it might be tempting to off load your years of coaching wisdom in one session to reaffirm that the athlete has made the right choice – use your first opportunity to make sure the athlete enjoys the experience and leaves feeling confident about the next planned session.
5. Check-In Building a new athlete-coach relationship is more than delivering a session, collecting fee’s and a providing free training t shirt. As the coach you always have a responsibility to recognise and reinforce the performance behaviours that

Proposed Causes and Prevention
acute hamstring injuries pose the greatest injury risk to elite and sub-elite sprinters (Woods et al., 2004; Edouard & Alonso; 2013; Askling et al.
2014). An examination of all injuries sustained at IAAF World Championships since 1987 suggests that acute hamstring injuries were responsible for approximately one quarter of all injuries in female sprinters and one third of all injuries for male sprinters. In addition to their prevalence, acute hamstring injuries also

required one of the longest recovery times of all injuries common to sprinters, significantly affecting training availability, competition preparation and sprinting performance (Askling, Saartok & Thorstensson, 2006; Askling et al., 2007). The most likely mechanism of acute hamstring injury during the sprinting action is a source of debate amongst scholars. The most commonly cited causes of hamstring injury in sprinters are detailed below:
Excessive Muscle Strain in Eccentric Contractions The original evidence for eccentric muscle contractions being
BELOW Phases of the running gait including the phases of hamstring eccentric contraction highlighted according to Yu et al. (2008)
the primary cause of hamstring injuries was originally based on research conducted in rabbits. Lieber & Friden et al. (1993) demonstrated that the primary cause of hamstring injury was not the quantity of force per se, but the magnitude of the strain during the period of eccentric muscle contraction. To understand how the finding of Lieber & Friden may relate to sprinting in humans, we can turn to
muscle lengths, power, flexions and contractions during the running action. Wood demonstrated that the hamstring muscles contract eccentrically in the late swing phase and late stance phase of sprinting. Based on this finding, it was hypothesized that hamstring muscle strains are most likely to occur in the late swing phase prior to footstrike (Thelen et al., 2005) and in the late stance prior to takeoff. This was studied more recently by Yu et al. (2008), who concurred that the potential for hamstring injury exists during the late stance phase as well as during the late swing phase of sprinting. They added that the hamstring muscles were at a much longer length at the end of the swing phase, which may result in a higher risk of hamstring injury during this phase. Page 40/90
Swing Eccentric Contraction
Large Eccentric Contraction
Analysis of the biomechanics of running suggests that hamstring strains occur during the end of the swing phase when the hamstrings are working to decelerate the limb while also controlling extension of the knee Woods et al.
The hamstrings are comprised of three muscles that all originate from the ischial tuberosity and are involved in hip extension and knee flexion - essential components of the walking and running action. A portion of the adductor magnus is also commonly considered as part of the hamstring muscles due to its common innervation and action.

Click here for an interactive model of the hamstrings courtesy of biodigital.com.
Excessive Muscle Strain in Concentric Contractions A recent study conducted by Liu et al. (2017) reaffirmed the risk of hamstring injury during the late swing phase, but challenged the existing wisdom by proposing that it was the early stance phase, not the late stance phase, that posed the greater risk of hamstring injury. The authors hypothesized that it was therefore the period of transition between swing and stance phases where hamstring injuries were most likely to occur. Liu et al. proposed that hamstring injuries during sprinting were most likely caused by large passive forces at the knee and hip joints, which result in the lengthening of the hamstring muscles. These forces were found to be highest during the transition between the swing and stance phases, where highforce eccentric and concentric contractions occur. In response to this paper, Yu, Liu & Garrett (2017) published a rebuttal stating that there was no theoretical or experimental evidence that supported the view that concentric contraction could contribute to hamstring injury.
Something Different? An editorial in the Journal of Sport and Health Science written by Walter Herzog (2017) challenged both proposed mechanisms and raised an important consideration regarding eccentric vs. concentric contractions. Herzog posited that it may not be the stretching of the muscle tendon unit that is important when considering hamstring injuries, but the elongation of the muscle fibres and fascicles. Previous

research has demonstrated that when muscle force increases, fascicle lengths tend to decrease (de Brito Fontana & Herzog, 2016). During the late swing phase of sprinting there may be both eccentric contraction (the stretching of
BELOW Phases of the running gait including the phases of hamstring eccentric contraction highlighted according to Yu et al. (2008)
the muscle tendon unit) and concentric contraction (shortening of the muscle fibres and fascicles). Herzog also proposed an alternative hypothesis, suggesting that hamstring injuries may primarily be caused by changes in hamstring activation caused by psychological factors during competition. He gives the example of sprinters rarely pulling up with an injury while leading a race - is this because of excessive strain when trying to catch up or from
the loss of focus when an athlete considers a race unwinnable?
Ultimately, it appears that at this stage there is not enough evidence to definitively understand the causes of hamstring injuries during maximum-speed running. However, we do have agreement that the

The importance of designing an effective training protocol has been severely understated... for preventing hamstring injuries in athletes
Understanding the potential mechanisms of hamstring injury during maximum speed running can assist in the development of injury prevention and rehabilitation strategies. Using the mechanisms proposed by Yu et al. and Liu et al., we will examine the coaching strategies that could be implemented and the current evidence supporting their use.

Planning an Effective Warm Up Theoretically, if hamstring injuries are exclusively caused by muscle strain during eccentric contractions, a warm up that increases the hamstrings muscle length would assist the prevention of injuries. This is supported by the finding that hamstring injuries tend to occur in the early stages of a training session, competition or season, where muscle lengths are generally shorter (Ekstrand &

specific warm ups that include static stretching held for 20 to 30 seconds are the most effective for injury prevention (Hartig & Henderson, 1999; Verall et al., 2005).
Warm up activities should mirror the movement patterns that will be performed in the main session.
Improving Flexibility A study comparing the hamstring flexibility between injured and non-injured athletes concluded that hamstring flexibility was the strongest predictor of injury risk (Worrell et al., 1991). There is evidence for reducing the occurrence of hamstring injuries by implementing a regular static stretching program that targets the hamstrings and quadriceps. Outcomes appear to be especially strong when stretching is conducted postexercise when the muscles are fatigued. Verrall, Slavotinek & Barnes (2005) demonstrated that hamstring stretches conducted during breaks in training and after a training session resulted in a significant decrease in hamstring strain occurrence when implemented as part of a holistic approach to injury prevention. The rationale given for its effectiveness is that stretching improved force absorption, making the muscles more resistant to a stretch injury. This finding supports a study conducted by Dadebo, White & George (2004), who found that among elite British football players, the absence or presence of hamstring stretching was the most important correlate of hamstring strain rates.
Improving Strength Nelson & Bandy (2004) demonstrated that in addition to static stretching, hamstring flexibility could also be developed effectively by an eccentric strength training method using a TheraBand. This was an important finding, as we know from the mechanism for hamstring strains proposed by Yu et al. (2008) that injury appears to be caused by eccentric loading at high velocity. By improving the hamstrings eccentric strength, we may reduce the likelihood of strains occurring (Guex & Millet, 2013). Comfort et al. (2009) built on the study by Nelson & Bandy and argued that for competitive athletes eccentric-specific strength exercises should be preferred over static stretching alone, as stretching does not adequately prepare the muscles for the sport-specific movements and forces encountered in competition. Injury prevention and rehabilitation should therefore incorporate a combination of static hamstring stretches with a selection of eccentric-specific exercises conducted to build the necessary range of motion and the specific strength that is required for sprinting.

Preventing Strength Imbalance Orchard et al. (1997) examined hamstring injuries in professional Australian Rules Football players and found that there was significant correlation between the occurrence of hamstring injury and two forms of strength imbalance. Injury was primarily encountered in the hamstring muscles on the player’s weaker leg and hamstring injury was significantly more likely in players with a lower hamstring to quadriceps muscle ratio. This finding was supported by Sugiura et al. (2008), who examined hamstring injuries in elite sprinters and noted that sprains always occurred on the athlete’s weaker side. The authors concluded that deficits in hamstring strength was associated with weakness during the eccentric action of sprinting and resulted in an increased likelihood of injury (Figure 3.1). The implications of these studies is that coaches are able to assist injury prevention by ensuring strength is developed on both sides of the body, using an appropriate balance of unilateral and bilateral exercises. The coach should also ensure that athletes are including an appropriate quantity of
It’s important to note that any well rounded strength and conditioning program should include both unilateral and bilateral movements. Anyone who claims that unilateral movements make you weak, or that bilateral movements are unnecessary, is missing the point. Both bilateral and unilateral exercises are associated with different applications and training adaptations, so don’t neglect one for the other Strength & Conditioning Coach, Giulio Palau
hamstring-specific exercises such as Nordic Hamstring Curls and Deadlifts, to prevent imbalance between hamstrings and quadriceps strength. However, not all evidence supports the view that strength Worrell et al. (1991) found that neither bilateral strength asymmetry nor the ratio of strength between hamstrings to quadriceps had a significant relationship with the occurrence of hamstring injury and Brockett, Morgan & Proske (2004) supported this finding in a study of athletes with a history of hamstring injury. Early clinical evidence also challenges the cause and effect relationship between strength imbalance and hamstring

strains. A single-case study of an elite football player with minimal bilateral asymmetry developed significant asymmetry in hamstring strength 5 days prior to suffering a hamstring strain (Schache et al., 2010). This may suggest that strength imbalance is a symptom rather than a cause of hamstring strains and more research may be required to better understand the relationship between the two. Overall, it is unclear whether strength imbalance is a significant contributor to hamstring strains, but ensuring a sprinter develops strength in their hamstrings and on both sides of their body is still important for achieving athletic success and should still be a priority for the coach.
Injured Athletes F I G U R E 3 .1
From Suguiraet al. (2008), showing athletes who suffered a hamstring injury had significantly greater strength imbalance between hamstring and quadriceps and greater imbalance between limbs
Fatigue and Low Energy There is evidence to suggest that athlete fatigue is an important contributor to the likelihood of a hamstring strain occurring. Mair et al. (1996) demonstrated that fatigued muscles are able to absorb less energy before reaching the degree of stretch that causes injury than non-fatigued muscles. This is likely to be especially important for hamstring strains caused by the running action, due to the large forces absorbed by the hamstrings during the latter part of the swing phase as the hamstrings decelerate the leg (Garrett, 1990). Fatigue may also play a role in exacerbating muscle imbalance, which as noted above, may contribute to hamstring injury. Rahnama et al. (2003) studied amateur football players and found that the ratio between hamstring and quadriceps strength became greater as the match went on and fatigue developed. The authors note that the amateur status of the participants from this study may contribute to these results, suggesting that a lack of muscular endurance may contribute to the growing imbalance with fatigue and that a potential implication for coaches is to develop the muscular endurance of endurance athletes to reduce the injury risk.

Foam rolling is becoming an increasingly popular component of a cooldown immediately prior to or after exercise. There is a growing body of evidence to support the use of foam rolling to aid recovery and improve athletesâ€™ range of motion (Peacock et al., 2014; Cheatham et al., 2015; Pearcey et al., 2015), although its effectiveness as a pre-exercise intervention

hypothesized that foam rolling between sessions may be an effective tool for increasing the range of motion at the hip and the knee joints, which can contribute to prevention of hamstring strains (Heiderscheit et al., 2010). A study that examined changes to the hip and knee-joint range of motion after a foam rolling intervention supported this hypothesis, demonstrating that increased range of motion increased and mechnical efficiency increased. The results suggested that foam rolling allowed the athlete to better absorb the forces (including eccentric forces) during the lunge action. While these findings are promising, more research would be required to know if foam rolling can prepare an athleteâ€™s hamstrings to be able to tolerate the high eccentric forces during the late-swing phase of the sprinting action. Foam rolling may also be an effective tool for aiding rehabilitation from hamstring injuries. In a literature review on the effectiveness of self myofascial release, Schroeder & Best (2015) concluded that foam rolling is likely to be an effective method of rehabilitation once strength and pain-free lengthening of the hamstring has been restored (Heiderscheit et al., 2010).

Hamstring strain injury is most likely the result of a multitude of factors and requires a multifaceted approach to prevention and management Anthony Barnett
Conclusion Running-related hamstring injuries are most likely to be caused by high intensity eccentric contractions during the late-swing phase of the running action. The coach can assist their athlete to avoid hamstring strains by developing their flexibility and strength, managing load to avoid excessive fatigue, implementing effective recovery strategies, avoiding strength imbalance (bilaterally and between hamstrings and quadriceps) and planning and implementing an effective warm up that prepares the athlete for the upcoming training session or competition.

It is arguably the best method currently available to obtain detailed biomechanical analysis of an athlete’s technique during competition or in their usual training environment. What Should the Coach be Looking For? The run up and take off are the most critical segments of the Long Jump for determining the distance of a jump. As a result, almost all performance diagnostic analyses and biomechanical studies have been designed for these segments. For example, a novice long jump coach may wish to begin by analysing the athlete’s take-off speed or angle. Linthorne et al. (2005) analyzed the optimum take-off angle for the long jump and found it is commonly between 15 and 300. However, it is

important to note the ideal angle will be individual for each athlete depending on their height, mass and technique. For the average physique of a male long jumper (~183cm and 75kg) the optimum angle will be between 20.5 and 25.50 whereas for women, the optimum angle will generally be between 20 and 240. Using the model developed by Hay et al. (1986) below and the calculated optimal data from Linthorne et al., you are able to use your preferred method of data collection to compare your athlete’s technique to the established optimal ranges.

Could the Future Edge in College Sports be Mental Wellness? Written by Bradley Donohue
e live in a sports-oriented culture. In the United States alone, there are about 8 million high school students participating in sports, almost a half a million students
in the National Collegiate Athletics Association, and many more play organized sports in club or intramural leagues. A small percentage of these students will go on to become elite college athletes, often revered by their universitiesâ€™ fans and alumni. While often glorified, these athletes also experience unique stressors that many of us may not understand (Gulliver, Griffiths & Christensen, 2012). These include performance demands that require extensive mental precision, fatigue due to irregular and strenuous training and competitive schedules, ongoing scrutiny from others, separations from loved ones, and a culture supporting intense emotional expression. While sport activities amplify opportunities to develop character, confidence, relationships and so on, research examining the impact of sport on mental health appears to indicate athletes may have similar or higher rates of psychological disorders as their non-athlete peers, but perhaps with special considerations (Rice et al., 2016). Six years ago, my research team initiated the first clinical trial involving collegiate athletes who were formally assessed for mental health conditions. Funded by the National Institute on Drug Abuse, the study was conducted to examine the effectiveness of two very different approaches to improving mental health in collegiate athletes. Specifically, we studied traditional counseling and psychological services compared with an experimental optimization program that emphasized performance, family inclusion and sport culture (Donohue et al., 2018). We wanted to learn whether there might be more effective ways to reach college athletes and help improve all aspects of their mental health.
In explaining the Optimization Model to athletes, we asserted that performance in sport, and life in general, is influenced by thoughts, behaviors and emotions.
Optimization Approach to Mental Health Although athletes have consistently reported the importance of coaches, family and teammates in their lives, traditional campus counseling and psychological services usually only involve the athletes in therapy sessions. Also, it has been our experience that traditional services rarely address sport culture formally, and they usually require athletes to evidence psychiatric symptoms, upset or dysfunction in some way in order to receive mental health services. We believe these practices deter athletes from pursuing counseling that may have been beneficial due to perceived stigma. In our trial, we altered a family behavior therapy that has demonstrated success in the improvement of mental health and social functioning, to address sport culture. To decrease potential for perceived stigma that sometimes occurs when pursuing psychological intervention, the Universityâ€™s associate athletic director at the time named the newly developed intervention The Optimum Performance Program in Sports, or TOPPS (click here for more information). Also, we made it possible for athletes to receive intervention regardless of mental health symptom severity. This was important because it positively branded TOPPS and normalized mental health along a continuum of optimization that could be shared by all athletes. We attempted to create a culture of optimization and not of illness. The providers of TOPPS are referred to as performance coaches, treatment plans are performance plans, motivational posters and university sport paraphernalia cover walls. Freely distributed T-shirts and water bottles have pictures of the TOPPS logo with catchy phrases that appeal to college students (for example, â€œWanna be on TOPPâ€?). In explaining the Optimization Model to athletes, we asserted that performance in sport, and life in general, is influenced by thoughts, behaviors and emotions.

Research Review Originally published by The Conversation
Optimization Approach to Mental Health In our trial, we formally assessed 74 athletes who were interested in participating in a goal-oriented program to assist their performance in sport and life, in general. They completed a battery of assessment tools that measured severity of mental health symptoms, factors interfering with sport performance, relationships with family, teammates and coaches, alcohol and non-prescribed drug use, and sexual risk behavior. Consistent with other studies, approximately half of the participants were determined to show evidence of a current mental health condition. We then randomly assigned them to traditional campus counseling or TOPPS. Prior to intervention, participants in each of the two experimental groups responded similarly to assessment measures and reported similar expectations for how well they would do in the program. Assessments occurred four and eight months after the initiation of intervention. Results indicated that participants in TOPPS and traditional counseling and psychological services were satisfied with the intervention they received. However, compared with participants in traditional services, participants in TOPPS attended more meetings, reported greater satisfaction with services, and demonstrated significantly better outcomes than traditional counseling, particularly when mental health/ substance use was more pronounced. Anonymous narrative responses were consistent with these results. For instance, one participant who received TOPPS reported: â€œThis program did wonders for me. Before starting this program, I was depressed about (the participantâ€™s specific sport was reported) and where my life seemed to be going. This program has rejuvenated how I view myself, others around me and the direction I know I need to go. (The sport was reported) is again a huge thing in my life, and I enjoy my friends and family more. The hardest thing that I still must improve on is my pot use. I have cut back and now am confident one day I will be completely clean when my life will depend on it most.â€? More research is needed to determine the effects of TOPPS, particularly in other specialized populations that require uniquely shared skill sets, such as artists, firefighters, musicians and military personnel. However, both quantitative and qualitative analyses suggest TOPPS may offer promise as an alternative to traditional intervention programs in collegiate athletes, regardless of their mental health diagnostic severity or competitive level.
The TOPPS Intervention The TOPPS Intervention conducted by Pitts et al. (2015) incorporated 12 meetings, lasting between 60 and 90 minutes held over a 3-month period.
Meeting 1: Program Orientation Information was provided about the TOPPS program and interventions. The subject was interviewed about his feelings of the program and his personal needs and objectives.
Meetings 2 to 12: Goals and Rewards In each of the subsequent meetings, dynamic goals and rewards were discussed with the athlete and his support personel. In meetings 2 and 3 the subject discussed and planned their objectives, and goal progress and strategies for achieving these goals was discussed in subsequent meetings.
Meeting 3: Performance Planning The subject was involved in setting the priority of the TOPPS intervention components. These were self-control, positive request, financial management, environmental control, career planning and reciprocity awareness. The subjects response determined the order and priority of the sessions to come.
Meetings 7 and 9: Self-Control This focused on the teaching of awareness of triggers and how to control them. Triggers such as thoughts, images, feelings and behaviours were explored based on the unique situation of the subject and strategies for managing the undesirable behaviour associated with those triggers explored.
Meetings 8, 10 and 12: Environmental Control The subject considered environmental stimuli that previously led to behaviours incompatible with their personal goals and how they can manipulate their environment to minimise these situations.
Meetings 10 and 12: Positive Request This intervention focused on teaching the subject how to communicate positively and makes requests that will motivate others to comply.
Meetings 11 and 12: Reciprocity Awareness Reciprocity awareness is geared at enhancing or maintaining positive relationships between athletes and their significant others, as well as addressing underlying issues associated with resentment and miscommunication, and building positive atmosphere in meetings.

This was supported by Moore (2009), who demonstrated that muscle protein synthesis may be optimally stimulated by protein intake of 15-25kg depending on the weight of the athlete. To optimize the ratio of fat-to-learn muscle loss, it is recommended that athletes lower their carbohydrate intake to approximately 40% of their total energy intake and increase

their protein intake to 20-30% (Abete et al., 2010).
Protein quality is most commonly evaluated using the PDCAAS. This tool measures a protein’s ability to provide adequate levels of essential amino acids for human needs and a human’s ability to digest it. Animal-source proteins
such as eggs, milk (including casein and whey) and most meats are considered the highest quality proteins and evidence supports their relationship with greater hypertrophy when consumed by athletes compared to soy-based proteins (Wilkinson, 2007). Milk proteins in particular have been suggested to be the most effective for supporting muscle protein synthesis, due to their particular richness in the essential amino acid leucine (Atherton et al., 2010). In their literature review, Phillips & Van Loon (2011) recommend milk or flavoured milk as the most effective and economical option for athletes who wish to optimise their muscle protein synthesis.
Preventing Dropout in the Ultramarathon According to conservative estimates, there has been a growth of over 500% worldwide in the number of runners attempting an ultramarathon from 2013 to 2017. For most of these first-time runners, reaching the finish line within the time-limit is their primary objective and the priority of the coach is to best prepare the runner for the unique physical challenges of running in excess of 43 kilometres. This article will examine the stressors that runners most commonly face while attempting the ultramarathon and what strategies the coach can employ in training and on race day to assist their runners to avoid, minimise or manage them.

The Interaction Between Stressors What the studies cited in this article did not examine was how the combination of factors work together to influence drop out rates. Anecdotally, while a runner may not drop out from a race if their only difficulty is a few blisters on their feet, if combined with gastrointestinal distress and mild dehydration, it would be more likely that a runner would decide to pull out. While there is no evidence to directly support this hypothesis in ultramarathon races, we do see a significant effect of the interaction of challenges on an athleteâ€™s likelihood of finishing other ultra-endurance events such as ironman and triathlons (Gublin & Gaffney, 1999; Baker, Cote & Deakin, 2006; Pfeifferet al., 2010). The priority for the coach should therefore be to look at the full range of common stressors that runners are likely to encounter during an ultramarathon and develop a strategy that aims to minimise all of their effects. The combination of factors may explain why pre-existing injuries are so strongly correlated with higher levels of dropout. Runners may feel capable of completing the race when only dealing with a mild ongoing injury that they have experienced throughout their training, but
The interaction between factors [a combination of stressors on the runner] was greater than any individual variable for predicting dropout
Hoffman & Foggard
when combined with other challenges that arise on race-day (e.g. gastro-intestinal distress and exhaustion) the physical distress is exacerbated and the likelihood of dropping out is increased. Ultimately, it appears that that there is not one individual stressor that is likely to cause a runner to drop out, but the effect of multiple stressors working together. The coach needs to prepare their runner in training for each of the most common stressors and develop raceday strategies that can assist management of symptoms if they occur during the race. The next section of this article will look at how the coach can assist prevention and management of these issues.

to take NSAIDs as a means of reducing pain or discomfort.
Training to Avoid Dropout Establishing a sufficient base of aerobic fitness is obviously essential for tackling any ultramarathon race.
However, the correlation
between a runnerâ€™s weekly training load and their likelihood of a runner finishing the race is not a simple linear relationship where the longer the distance run in training results in a greater likelihood of finishing. Instead, what we see is that the likelihood of finishing an ultramarathon increases as the runnerâ€™s weekly training load increases, but only up to a certain distance. Above that distance, there does not appear to be a significantly improved likelihood of being able to finish a race. Evidence suggests that a maximum weekly training load (prior to the taper period) ~30% greater than the distance of the race will be optimal for preparing runners to reach the finish line, but any additional training is unlikely to increase the likelihood of finishing. While this has been supported by studies examining 50km and 100km races, no research has studied the relationship for longer distance races. However, it should be noted that weekly training load has been shown to be correlated with faster race times, suggesting that runners who are targeting a specific time or finishing position would most likely benefit from a maximum weekly training load greater than 150km for a 100km race. This is why understanding the objectives of your runners is important prior the design of an effective training program.
Coaching Interventions Gastrointestinal Issues Prevalence Gastrointestinal issues are the most widely reported stressor facing ultra-endurance runners and the limited data that exists suggests that it is a significantly greater issue for ultramarathon runners than in the marathon (Rehrer et al., 1992; Baska et al., 1990). The prevalence of symptoms experienced appears to increase in association with increases in the distance of the event, with approximately 37% of participants reporting symptoms of nausea in a 67km event and 55% of participants reporting nausea in a 161km event (Glace, Murphy & McHugh, 2002). A study by Gill et al. (2015) demonstrated that “nearly all” partcipants from a 24-hour ultra-marathon had blood markers nearly identical to patients admitted to hospital with sepsis. This occurred a result of bacterial endotoxins leaching into the blood during prolonged periods of exercise, triggering the body’s immune response. Symptoms Gastrointestinal issues mostly presented with the following symptoms: •
Nausea or vomiting
Inability to eat or drink
hyponatremia, energy depletion hypoglycemia, symptoms also included: •
Inability to concentrate
Loss of consciousness

Prevention / Management 1) “Slow down and cool off” Ultrarunning expert Jason Koop’s first recommendation for runners who are experiencing a quesy stomach is to slow things up and allow the body to cool down. Pace should be adjusted (to a slow walking pace if necessary) and the body cooled by removing any additional layers or by splashing a small amount of water on a towel or directly to the skin.

(Qamar & Read, 1987). This results in a slowing or complete stop of the digestion process and the beginning of symptoms associated with gastric distress. Damage to the gut can also occur in ultra-endurance runners as a result of the prolonged physical disturbance caused by the bouncing of the running motion (Peters & de Vries, 2001).
Koop advises his first-time ultramarathoners to drop the pace as soon as symptoms appear as the sooner you can allow sufficient blood flow to return to the digestive system, the sooner the runner will be able to recover.
2) Training History Gill et al. (2015) provided clinical data to demonstrate that training age was positively correlated with higher levels of an anti-inflammatory agent that allowed their gut to better cope with the stress brought on by exercise. It is worth nothing that it was specifically the number of years the runner had been training, rather than the distance or intensity of training that best predicted the runner’s resilience to gastrointestinal issues. The implication for the coach from this finding is that a runner should gradually progress to their first ultramarathon and ideally have at least 18 months of training prior to their first race. 3) Hydration Costa (2014) believes that the maintenance of euhydration should be the runner’s primary priority for preventing gastrointestinal
Euhydration should be rehearsed in training so the runner has a good understanding of the amount of fluid that needs to be consumed during the race and their gut is ‘trained’ for intaking the required quantity. The importance of fluid intake was demonstrated in a study by Stuempfle, Hoffman & Hew-Butler (2013), which found that lower fluid intake was associated with GI distress in ultramarathon runners. This was supported by a qualitative observation that fluid intake appeared to be correlated with how runners felt after prolonged cardio exercise, with those
Key Hydration Considerations Sodium supplmentation assists the runner to maintain their body weight throughout exercise, but there is no evidence that it supports a runner’s performance or that a loss of body weight less than 3% has a negative effect on the ultra-endurance runner (Hoffman & Stuempfle, 2014; Hoffman & Stuempfle, 2016; Valentino et al., 2016).

Conversely, coaches need to be aware of the risks of overhydration, with very high levels of fluid intake during an ultramarathon correlated with confusion and dizziness (Glace, Murphy & McHugh, 2002).

small meals every 2 to 3 hours depending on digestive capacity. •
Consume 20-50g /hour, including a combination of salty and sweet foods.
Ensure that food is well chewed, potentially more than a runner is used to. Food particles larger than 2mm may restrict gastric emptying and add stress to the digestive system.
On the morning of the race, ensure a breakfast high in proteins and carbohydrates is consumed. Corinne recommends including whole-grain toast, eggs, ham or lean meat, a fruit puree and oats or museli.
Try and time bigger meals with uphill sections where there is less mechanical stress (bouncing around) on the digestive system.

â€œAt foot strike, the ground pushes backward on your shoe, your insole pushes backward on your sock, and your sock pushes backward on your skin. As you push off the ground, these forces between your skin and sock, sock and insole, and shoe and ground all reverse direction. The problem is that the surface of your skin is pliable (after all, it is called soft tissue). As your body applies these shear forces, your soft tissue (skin on the feet) moves more than your skeletal system (rigid bone). This out-of-sync movement between your skeleton, soft tissue, sock/ shoe, and shoe/ground is what ultimately causes the frictional force that leads to a blister. Your shoe and sock move against your outer layer of skin (epidermis) more than your outer layer of skin moves against your inner layer of skin (dermis). As the bump and grind between these two skin layers continues, the layers eventually separate. Once this separation occurs, fluid fills the void due to hydrostatic pressure. The result is a fluid sac between the newly separated layers of skin bordered by yet-to-be separated layers along the edges.â€? Jason Koop, Training Essentials for Ultrarunning
Hotspots / Blisters Prevalence Blisters are an almost unavoidable symptom for ultramarathon runners, especially for firsttimers who are yet to develop the callouses and find the personal measures that work for them. However, this is an issue that almost all runners will encounter at some point and the coaching focus should be on management and education. Symptoms Pain is the most obvious symptom, usually combined with irritation of the skin, including bruising and blood. What may start as an annoying but relatively harmless irritation can quickly turn into an ongoing pain that completely changes the running gait. This is where blisters are most likely to result in a DNF, where changes to the runner’s natural rhythm result a decrease in pace, stress on different parts of the body, changes to the nutritional plan and adverse psychological impacts. Causes The vast majority of blisters on the feet developed during running are friction blisters, caused by the forces generated during footstrike. The occurrence of blisters is increased with additional heat and moisture. Blisters can also be caused by the friction between clothing and the skin, making it important to test out race-day apparel repeatedly in training. Prevention 1) “Training, Training, Training” There is strong evidence to demonstrate that repeated exposure to the frictional forces encountered during running improve the body’s ability to prevent blisters from forming. It is important to remember that blisters on the feet are caused by the unique relationship between shoe, sock and foot, making it important to train in the same footwear that the runner intends to wear during the race. 2) Use the Right Equipment Finding the right pair of shoes and socks should be a runner’s priority from the very start of the training phase. Evidence suggests that friction blisters can be significantly reduced by running with shoes and socks that have been correctly fitted (Knapik et al., 1995). Experimenting with different lacing techniques may also be an effective way to reduce friction blisters - click here for a guide on different methods suited to different feet shapes. There is some evidence to demonstrate that acrylic fiber socks are more effective than natural cotton fiber socks for preventing blisters (Herring & Richie, 1990), but these socks should be constructed with dense padding to enhance the physical properties of the fibers (Herring & Richie, 1993). Wrightsock offer a range of prodcuts specifically for ultrarunners using specifcially made acrylic fiber socks - however they tend to trap moisture and become relatively heavy once wet. If you’re running a wetter course or a heavy sweater you might be better off trying a lighter sock. New Balance’s Coolmax socks have also been very well-reviewed and offer a lighter alternative. When it comes to choosing the right shoe, it will come down to trying on a few different models and finding what feels ‘right’ for the runner. If you are looking for a few models to recommend to your new runners, the following models are generally considered to be among the best models for trail and ultra runners: ASICS Men’s Alpine XT Running Shoes - Full review here Salomon XA Elavate J Trail Running Shoes - Full review here New Balance Hierro V3 Running Shoes - Full review here Brooks Caldera 2 Running Shoes - Full review here Part 2 in the next edition will look at more ways ultramarathon coaches are able to assist their runners prepare for their first race.

term strategy for high jump success.
The Appropriate Age to Introduce the Fosbury Flop It is recommended that athletes begin to learn the Fosbury Flop technique no earlier than 13 years of age. Any decision about when to introduce the Fosbury Flop technique to a young athlete must be based on the individual athleteâ€™s physical maturity (biological age) and coordination. It is important to remember that a difference of up to two years between a childâ€™s chronological age and their biological age is within the normal range of variation, and differences up
to four years have been known. Therefore, some children may have the physical maturity and coordination to commence training at 13 years of age, whereas other children will not possess the same competencies and strength until 15 years or older. The decision about the appropriate age to commence learning the Fosbury Flop should be left to experienced Accredited Coaches and Physical Education Teachers and be based on the individual physical and mental characteristics of the athlete. In alignment with the Development Model of Sports Participation (Cote, Murphy-Mills & Abernathy, 2007) and the Athletics Coach Education Framework, early specialisation should be avoided. A well-rounded skills and coordination development program that incorporates running, jumping, hurdling, throwing and multi-sport experiences should be the domain of the athlete in the 10 to 15-year-old age group.
Prior to Commencing the Fosbury Flop Prior to deciding when an athlete is ready to start learning the Flop technique, the focus should be on jumping with the Scissors technique from a straight-line approach to develop the physical attributes required to perform the Fosbury Flop effectively. This should be done in an engaging and enjoyable environment that supports the athlete’s long-term participation in the event.

the technique that they are using?” Remember that the pressure of competition will exacerbate technical deficiencies as the athlete strains for maximum height. Level 5 Coaches Peter Hannan and Gary Bourne recommend the following points for the coach to consider when determining whether an athlete is ready to perform the Fosbury Flop in competition: Consistency The ability to perform the run-up, take-off, flight and landing phases of the Fosbury Flop consistently in a safe manner. Foot Plant Planting the foot at approximately 20 degrees to the bar at take-off. This is essential for ensuring that the optimal takeoff position can be achieved. It also greatly reduces the risk of injury, particularly to the ankle and knee, caused by forces being wrongly directed through those joints. The final angle of approach (flight path of the final stride) of a Flop High Jumper is between 30-35 degrees to the bar. The change in direction of the Take-off foot plant is approximately 10-12 degrees to the direction of the final stride. This means that the final angle of the foot plant to the bar is around 20 degrees. This angle should point well inside the far upright provided the take-off point is not too far down the bar – a maximum of 50-70cm along from the approach side upright. Take Off Position Relative to the Bar The athlete should take off approximately 70cm along the bar. The bar is 4.0m long and the best clearance position is over the middle of the bar, 2.0m from the upright. Ideally, the take-off should be 70cm along and 70-75cm out from the bar with a horizontal velocity of 3.0 – 3.5m/s (half run-up speed), a vertical angle of take-off of 50 degrees and a final angle of flight in relation to the bar of 20 degrees. This will place them close to clearing the centre of the bar.
Achieving the desired take-off position greatly increases the likelihood of the athlete safely clearing the bar. It allows the athlete to maintain a lean away from the bar until foot plant, which assists in generating the required rotation for a successful and safe clearance. This reduces the likelihood of athletes throwing their lead arm or head over the bar to generate unnecessary rotation. Athletes who take off further than one fifth of the length also run the risk of hitting the upright or missing the mat on landing. Take-off Posture The athlete’s body should be at right angles to the bar at takeoff, holding a tall posture with their body weight above the planted foot. Bar Clearance At the highest point of the athlete’s jump, the line of the athlete’s hips should be parallel to the crossbar, and slightly higher than their knees and shoulders. Landing The athlete should be landing at the base of their shoulder blades or at the highest, on their shoulder blades. Landing should be comfortably within the confines of the High Jump mat (to ensure the equipment being used is supporting this outcome, see recommended ‘5 – High Jump Equipment’ for recommended mat dimensions). It is recommended that the coach should observe the athlete’s ability to perform these six points with consistency before they are ready to use the Fosbury Flop in competition. Signing Off Prior to attempting the Fosbury Flop in competition, it is recommended that athletes younger than 18 years of age are signed-off by: i) Their personal Accredited Athletics Coach using the template included.

Osgood-Schlatter’s Disease Description: A common cause of knee pain in growing adolescents, Osgood-Schlatter’s disease is an inflammation of the growth plate where the patellar tendon attaches to the tibia, known as the tibial tubercle. Symptoms: Knee pain, swelling and tenderness at the tibial tubercle. The athlete may also experience tight hamstring or quadriceps muscles. Causes: Osgood-Shalatter’s Disease can affect anyone during growth spurts, when bones, muscles and tendons are undergoing rapid changes. However, High Jump increases the risk for this condition as a result of the additional stress on the growth plates, tibia and patellar tendon. Prevention: Avoiding sudden spikes in training load and ensuring adequate recovery between sessions is the most effective prevention tool. Gentle range-of-motion exercises and stretching to prevent stiffness may also be prescribed by a physiotherapist. Treatment: Rest, ice and protection. A doctor will usually focus on reducing pain and swelling through prescribed rest, stretching and possibly anti-inflammatory medication. As it affects the growth plate, most symptoms will disappear when a child completes the adolescent growth spurt.
Plantar fascilitis Description: The inflammation or damage to the plantar fascia, the fibrous band of tissue extending from the heel bone along the sole of the foot towards the toes. Symptoms: Plantar fascilitis most commonly presents as pain
under the heel or in the arch of the foot. Depending on the stage of injury, the pain is commonly greatest with the first steps and improves as the body warms up. Pain will usually return after exercise and be especially bad the morning after training. Causes: Causes of plantar fascilitis can be divided into traction or compression injuries. Traction plantar fascilitis is the most common amongst jumpers. Traction plantar fascilitis are caused by repeated overstretching of the plantar fascilitis. This can be caused by poor foot biomechanics or weakness of the foot arch muscles and exacerbated by footwear with poor support. Tight calf muscles or a stiff ankle increase the risk factor for developing plantar fascilitis. Compression plantar fascilitis is caused by direct trauma to the plantar fascia. Prevention: As foot biomechanics are the main predisposing factor for the injury, working with a biomechanist to correct the athlete’s running and jumping biomechanics may be an effective prevention for athletes with a history of the injury. Keeping the High Jump area clear and ensuring appropriate footwear is worn can assist prevent compression plantar fascilitis. Treatment:
Rest, ice and protection. A doctor may
recommend anti-inflammatory medication. A physiotherapist may develop a strength and flexibility program to strengthen foot arch muscles and improve range of motion. With early treatment, significant recovery is usually experienced within two months.
Prevention: Developing calf and anterior tibial strength, flexibility and endurance can assist in preventing MTSS in conjunction with wearing appropriate footwear and avoiding rapid changes in training intensity. Treatment:
Rest, ice and protection. Lower limb impact
should be reduced until inflammation has been removed. A physiotherapist may recommend light massage, myofascial release or deep tissue massage.
Patellofemoral Pain Syndrome Description: The deterioration and softening of cartilage on the under surface of the knee cap. Jumpers are at significant risk of developing the injury due to the repeated stress experienced by the knee joints during the approach and takeoff action, especially if the athlete has an incorrect technique that exacerbates load on the knee. Symptoms: Pain and tenderness over the patella tendon, exacerbated during activities that apply pressure to the knee joints (e.g. jumping and landing and feet). Onset of pain is normally gradual rather than traumatic. Another common symptom is a ‘grinding’ sensation when bending or extending the knee. Causes: Runner’s knee occurs when the patella (kneecap) rubs against the femur (thigh bone), leading to deterioration of the patellofemoral joint. It commonly occurs as an overuse injury from repeated stresses to the knee but may also result
Medial Tibial Stress Syndrome (Shin Splints) Description: Commonly referred to as ‘shin splints’ MTSS is an overuse injury that results in the inflammation of the muscles, tendons and bone tissue around the tibia (shinbone). Symptoms: A pain experienced anywhere along the shinbone from the knee to the ankle. Pain generally develops gradually over several weeks and may be felt throughout and after any activity. Less frequently, swelling develops in the lower leg with small bumps along either side of the shin bone. Causes: Overpronation during the High Jump runup and takeoff is believed to be a significant contributing factor to MTSS. This is where the athlete’s foot strike during the approach has an excessive flattening of the foot arch, resulting in the force not being evenly spread throughout the foot. This places increased pressure on the arch of the foot and greatly increases the stress placed on the lower leg. Weakness or tightness in the posterior muscles may place
from poor biomechanical control, weak hamstrings and quadriceps muscles or abnormal muscle imbalance between the adductors and abductors. In some cases, patellofemoral pain syndrome is caused by misalignment of the knee due to a congenital condition. As highlighted in Section 3, it is important to have an athlete signed off by their Primary Care Physician prior to commencing regular Fosbury Flop training. Prevention: Developing calf and anterior tibial strength, flexibility and endurance can assist in preventing MTSS in conjunction with wearing appropriate footwear and avoiding rapid changes in training intensity. Treatment: Rest, ice and protection. The goal of treatment is to reduce pressure on the kneecap and joints. With enough rest, cartilage damage will often repair itself. In some cases, surgery may be required to correct misalignment of the knee, to release tension and allow for a greater range of movement.
excessive strain on the on the muscles in the front part of the lower leg.
Sprained Ankle Description: An acute injury that results in the overstretching or tearing of the ankle ligaments. Symptoms: Depending on the severity of the sprain, a sprained ankle may result in mild pain during weight bearing exercises, or ongoing severe pain. A sprained ankle can affect the athleteâ€™s balance, movement and in moderate and severe cases, result in severe swelling and stiffness. Causes: Sprained ankles are an acute injury that result from a force being applied to the ankle joint, which causes an excessive range of movement. The biggest risk factor for a sprained ankle is having a previous ankle injury that has not fully recovered. Other causes include lack of ankle strength, lack of ankle flexibility and poor balance. Prevention: Sports Medicine Australia recommend regular agility, flexibility, balance and strengthening exercises as the most effective method for avoiding sprained ankles. Athletes who have a history of sprained ankles should avoid returning
Causes: Incorrect landing technique that results in the athlete landing on their neck places high flexion loading on the cervical spine. Prevention: Establishing correct landing technique from the athleteâ€™s first introduction to the Fosbury Flop reduces the loading on the neck. Coaches must take action when they observe an athlete who continues to land on their neck to correct the issue. This may necessitate removing the bar until the athlete has perfected the desired landing position. Treatment: All spinal issues should immediately be referred to a medical professional for diagnosis. Generally, return to sport will not be approved by physicians until the athlete is asymptomatic and full neck strength and function is restored.

the final four strides prior to take-off by ‘steering’ towards the takeoff point. This can be most easily achieved by marking the curve on the ground with chalk or tape during training. Required Lean-Away at Take Off Successful Flop High Jumpers exhibit very little or no leaning back through the trunk at touchdown for take-off. However, they do exhibit a significant “lean-away” position (15 degrees and often more) that is acquired as a result of running fast on a curve. This lean-away (not lean-back) is what produces the necessary lowering of the centre of mass during the preparation for take-off. The reason for the upright trunk position at touchdown is that the Flop technique capitalises on “lean-away” gained from good curve running, along with the take-off foot out and across the body in front, during the eccentric phase of the take-off. The horizontal and centrifugal braking that occurs at touchdown about the horizontal and sagittal axes of the jumper stretches the tendons and muscles involved in take-off while allowing the athlete to minimize their take-off time. This elastic energy is available immediately at the end of the eccentric phase for the rapid upward acceleration of the body. It is also supported to varying degrees by concentric contraction during the latter half of take-off time. The take-away is that it is important to develop a technical model where the jumper arrives at the take-off with minimal or no lean back but a lean away of approximately 15 degrees. Rotation Ask the athlete to run five strides in a straight line, then plant the foot straight and drive their swing leg knee forcefully upward. At the same-time they should reach vertical upward with the arm on the swing leg side. Ask them to hold their landing position. After landing ask them to note the direction of their hips and landing

foot. They will have rotated in the air approximately 90 degrees. Point out to them that this rotation is a consequence of the angular momentum gained from the eccentric force generated during the take-off movements on one side of the body and then transferred to the whole body at take-off (the definition of an eccentric force is a force directed outside of the CM). The rate of rotation (in individual cases) is a matter of manipulating the angular momentum of the body in flight, thus increasing or decreasing their angular velocity of the body (how fast and how far they will rotate) by raising the arm and maintaining a vertical posture – or not. Give the rotating ice skater or gymnast examples where distributing the mass of the body further than the axis of rotation slows the rate of rotation and bringing the mass closer speeds rotation up. Get them to try this several times, emphasising that it is not necessary to drive the knee across the body during take-off. Get them to try it while extending both arms outward (less rotation) or with an extended (straight) swing leg (much more rotation).
Raising the Centre of Mass at Take-off Look for toe up, knee up and arm up and ensure that the centre of mass is above the take-off foot. Knee Drive Speed Look for a fast knee drive through the creation of a short lever of the swinging leg and a longer penultimate stride and shorter take-off stride. Ensure that the knee of the swinging leg is not trailing the hip at touchdown for take-off. Clearance Position Ask the athlete to drive the arm up or reach vertically during the take-off movement, then guide it along the bar during the early flight before reaching under the bar toward the lead leg foot during clearance. This reduces the moment of inertia of the body about its horizontal axis during clearance, increasing
High Jump Equipment Using appropriate equipment, ensuring that it is of a suitable condition and complying with all relevant Education Department, Athletics Australia or IAAF recommendations is essential for avoiding injuries during High Jump.

Flexi Bar Using a Flexi Bar is an appropriate modification for developing athletes that avoids injuries that may occur when an athlete lands on a fibreglass bar. It is important that coaches ensure that when using a Flexi Bar that the uprights are secured sufficiently to ensure that they do not collapse inwards and fall on the athlete should they become entangled in the bar during their jump. High Jump Spikes Appropriate footwear contributes to avoidance of injury that may occur when an athlete slips during their approach. High Jump spikes differ from sprinting spikes in that they include spikes in the heel to offer additional grip and reduce the likelihood of loss of traction. This is especially important when planting the foot for take-off. Video Equipment The regular use of a video camera or mobile phone capable of slow-motion playback is important for providing accurate feedback on curve running, touchdown and take-off positions, and clearance position. Even the most experienced coach will be unable to see all the important information during the phases of the Fosbury Flop without the aid of video equipment, and recording is an essential tool for analysing the technique of a jumper. It also assists athletes’ own learning by giving them a visual understanding of what they did. Triangular Bars In no circumstances should triangular or square bars ever be used.
