KTA: GAKGUNG • HACKING THE DARKSIDE • ARROW DYNAMICS ISSUE 139


World record clarified On 9 November 2019, a junior world record at 25 metres was broken by Italy’s Tatiana Andreoli with 588 points. The Swedish archery federation raised the issue that Petra Ericsson, who broke the 25-metre senior mark with 592 points in 1991, had also broken the junior record as she was aged 17 at the time. World Archery ruled that while Petra’s score was higher, junior records were only officially recognised from 1995 and therefore did not exist when the tournament was shot in 1991. The junior record has been awarded to Andreoli while the senior record remains Ericsson’s.

Barebow finally gets official world Marks

Barebow archers will be able to claim world records at indoor and outdoor competitions from 15 January 2020, when the new rulebook comes into effect. The changes required to add the 44 records for barebows were approved at World Archery Congress in June. Records are being introduced for outdoor and indoor ranking rounds, and can be claimed in cadet, junior, senior and masters age groups.

Unruh on the mend Rio 2016 Olympic silver medallist Lisa Unruh shot her national finals in Berlin in 2019 in some pain. An MRI revealed a tear on the supraspinatus tendon; a difficult injury for an archer staring down the barrel of Tokyo 2020. She underwent shoulder surgery under general anesthesia in November, and is apparently healing well. "Three weeks after the operation I was just able to do the first exercises." "The mobility has already improved significantly. I am daily at the moment in rehab and physiotherapy. Luckily the injury wasn't quite as bad as we initially suspected." Unruh had previously had problems with the same shoulder, but they dissipated without surgery. "I can't say exactly when I am shooting yet, I will start with strength training get in, gradually put pressure on the shoulder, and then we have to decide when

the official shooting training can begin. In any case, I am looking forward to finally shooting pain-free again." As Bow went to press, Lisa had recovered enough to begin winter training with the German team in Turkey.

Good Karma

The mononymously-named Karma has become the first athlete from Bhutan to qualify an Olympic quota place in any sport. She won a recurve women’s archery spot for Tokyo 2020 during the Asian continental qualification tournament in Bangkok. Six spots for the

Sarah Prieels of Belgium broke the compound women’s 60-arrow 18-metre ranking round world record that only stood for three weeks. She shot 597 out of a possible 600 points during qualification at the 2019 Roma Archery Trophy. The previous record of 596 was set by Ella Gibson at the previous leg of the Indoor Archery World Series in Luxembourg on 23 November. Brazilian para archer Jane Karla Gogel, who set a new compound women’s open record in Luxembourg with 575, scored 577 points at the same event to add two to her own record. (More about the Roma Trophy on page 44).

Olympics were awarded during the 2019 Asian Archery Championships. Karma previously competed at Rio 2016 under universality rules, as had Bhutanese athletes in previous Olympics, but this event marked the first qualification by right.

RELEASE THE PRESSURE

Most modern archery gear needs little more than a wipe down with a cloth, but if you shoot field, for example, or like to stay outdoors longer than most you may need to strip things down a little more than that. Compound releases can get gunked up and may need a little more attention. If it's really time for something new, TRUBall have released the G02, a handheld release that can be fired as either an index trigger or pinky trigger with the simple adjustment of two set screws. Each trigger option is independent and adjustments can be made to one without changing the other. It comes as standard with three sized finger rings (small, medium, or large), allowing the archer to choose the ring size that best fits their hand, and you can select three different positions for your thumb.

FALLING THROUGH THE CRACKS

It's time to go through your arrows – all of them, even the ones in the cupboard – and check for any cracks or dents in the shafts. Your arrows are the single hardest wearing item of all your equipment; they take quite a bit of punishment (and damage if your groups are nice and tight). Whether you shoot all carbon, carbon-aluminium or pure aluminium arrows you should check for any cracks or dents in the shafts. Impacts in the target will weaken the arrow and can cause it to fly badly or even splinter when shot. Spin each arrow by hand (or use an arrow spinner) – a bent shaft will not fly straight and consequently will not group with your other arrows. If you use carbon arrows, flex the shaft to check for hidden cracks. Hold each end of the arrow just below the point and the nock, then gently flex the arrow away from you, putting at least one to two inches of deflection into the shaft. Listen out for any clicking or cracking noises, if you hear any discard the arrow: it’s damaged and it’s not safe to shoot. Don’t forget to rotate the arrow a few times and check it from every angle as some cracks can be very small and hard to detect. >

If you're looking for a new set, the new Easton RX7 aluminium indoor specialists have been receiving excellent notices from archers across the board, particularly with regard to forgiveness. From around £10 per shaft, they're a lot more affordable than many other high end arrows. More at eastonarchery.com

CASTING HEXES

Bow can make one decision for you which you should have made years ago: throw out all your Allen wrenches. Also known as hex keys, they can be metric or imperial and have a habit of proliferating, supplied as they are with a lot of equipment. Before you know it, you have dozens of the things floating around between drawer and bowcase. They are cheap and widely available, and frankly the best thing you can do is throw the lot into a bin. The most important tools for archers are a pair of the multi-tool Allen wrenches sold by archery companies that include both imperial and metric bolts. A pair: one for the archery drawer, one for the bow case. At least! (Note: the sole Allen key I kept was an extra-long one sized for Hoyt recurve tiller bolts, which is handy when making changes to poundage and tiller).

Food Glorious Food What the pros eat in competition. By Mimi Landström

I

t’s wintertime, and you may well have been indulging a little in the last month or so, and perhaps wondering how to get back to that next level in the New Year. You probably know a little about what to eat and what not to, but there really isn't a lot of archery-specific nutritional information. So we asked the question: how do elite archers keep focused, fuelled and energised during training camps, competition and being away from home during the indoor season? We spoke to six different archers from around the world: Naomi Folkard, Sjef van den Berg, Gabi Bayardo, Ella Gibson, Mackenzie Brown, and Paul Tedford about how they optimise tournament food, their food habits and any secrets that they hold.

Naomi Folkard Four-time Olympian for GBR Naomi has had a long and intense outdoor season, but now heading into a series of overseas training camps with the GB Olympic squad. “For breakfast I have two boiled eggs with a slice of granary toast on a training or competition day. Lunch consists of cottage cheese and some coarse oatcakes. My snacks include Greek yoghurt, natural dried fruit and cashew nuts. Make sure that the dried fruit has no added sugar." “I think it’s more important to maintain energy levels rather than maximising it. Do this by choosing low GI foods, or level high ones out (fruit) with low ones (nuts). This should be the plan every day, so your body is used to maintaining energy." “When away, I will look at the schedule and eat when I can, avoiding large amounts of food within an hour prior to competing. Obviously, schedules can overrun, so my advice is making sure snacks are on hand, just in case. Also remember that grazing is much better than too much in one go. And don't forget it is a myth that you can maintain a “sugar high” by eating more sugar.”

Hit The Right Note How one elite archer keeps things tidy. By Günter Kuhr

S

o you want to be good at this archery lark, right? You are making notes, yes? On every aspect of your training? If you aren't, you may be missing a cornerstone of elite training. Recording score data digitally on a smartphone app has some advantages, particularly in terms of being able to track scores across time, but requires you to maintain a charged battery on the range, plus opening up the possibility of distraction from training (see Bow 138). It's worth noting that most elite archers still use good old-fashioned pen and paper; some scientists have argued that the very act of physically writing locks information better into the brain. Michelle Kroppen, now a solid fixture on the German national recurve team, finished 2019 ranked tenth in the world. In 2018, together with Elena Richter and Lisa Unruh,

the 22-year-old Berliner from Berlin secured the team world title in Yankton / USA. In 2019, she took a silver medal in the individual competition at the World Cup in Salt Lake City, and a team silver at the Antalya World Cup. She was part of the same team that secured the first German women's team qualification to an Olympics for twenty years – and also managed a fourth place individual finish at the same tournament. Kroppen has been shooting for 14 years, and in addition to her coaches, her shooting notebooks with all the data, analysis and solutions used has always been an important guide on the way to the very top of the sport. She tells us what goes into hers.

START FRESH Every year at the beginning of the season Michelle starts with a new shooting book. This

is where the athlete begins to record all the important details about her current equipment. Previously, she tended to use the same gear as her teammates, but that changed in 2018. "Last year I decided I have to find my own thing, my own bow setup, technique, whatever works best for me.”

THE BOW: DETAILS Michelle Kroppen has two competition bows, and notes all the details of the two sports bows in her shooting book. Everything. This information includes, for example: bracing height, the nock point elevation, tiller, the measured poundage, button settings and also the stabilisers used with length and weight information. An additional page remains free after the entry for notes on the material changes that occur within the season. You may think you know how your bow is setup, but

Blowing in the wind To show how the arrow aligns with the airflow: in the top diagram, the arrow is travelling to the right, in no wind but with an initial angle of attack and a small amount of flex. It is sampled every 20 msec. The second shows the arrow aligning with the resultant airflow in wind. You can see that the drift in wind at 70m is a lot greater than at 50m. Essentially, most of the deviation happens in the last 20m of the range.

lift than for the drag, so the lift does most of the work. If the arrow is not currently aligned with the airflow (for example, as it leaves the bow) the aerodynamic forces act to move it closer to alignment. Usually it will overshoot and then need to move back in the other direction – engineers describe this behaviour as ‘under damped'. Typically, the arrow will travel about 20m for each cycle of this oscillation, and this is the behaviour you see if you watch along the arrow’s path from behind. Nevertheless, the drag from the fletches is important in relation to the arrow’s lateral movement in wind. Interestingly, it is not just the drag from the airflow over the fletch surface that matters but also the fletch profile drag – from its edges. That means that for a given fletch area we will do best by selecting a low profile fletch – longer rather than higher for a given area. The other important function of the fletching is to spin the arrow – the aerodynamic

TYPICALLY, FOR AN X10 ARROW SHAFT AND A FLETCH ANGLE OF ABOUT 1 DEGREE THE ARROW WILL ROTATE ONCE FOR ABOUT EVERY 2-3 METRES OF TRAVEL roll. I see many archers placing their fletches directly along the arrow shaft, with no fletch angle. This is giving away points, since arrows group better if we spin then. The lift from the fletches depend on their angle to the airflow. This means that once the arrow is spinning at the right rate to have the resultant airflow directly along the fletch there is no lift and that will be the stable rotation rate. Typically, for an X10 arrow shaft and a fletch angle of about 1 degree the arrow will rotate once for about every 2-3 metres of travel (which is sufficient). While the arrow is attached to the string it of course cannot rotate. The rotation starts when the nock leaves the string. After about

10m of travel the spin rate will typically be reasonably close to the stable rate. Note that the time it takes for the rear of the arrow to pass the riser after the arrow leaves the string is very short, so the angle of the fletches as they pass the riser is very close to the same as when the arrow is attached to the string. Once at the stable rotation rate the drag is the same as if there was no fletch angle. It takes a small amount of energy to get the arrow spinning and that energy comes from a (very) small decrease in the arrow’s speed. At most it is only a few ft/sec so practically it is nothing, particularly when considering the decrease in group size from spinning the arrow.

he Berlin Open is one of the more respected indoor tournaments in Europe. Running since 2012, it has moved venues – and management teams – more than once. There is now ambition here to be one of the major indoor tournaments in the world. They certainly have the city for it; one of the world's most enduringly fascinating, and they also now have the venue; the Horst Korber sports hall in the west of the city, in the shadow of the clocktower of the famous Olympiastadion. The hall is modern and benefits from good lighting and configurability: a finals field is able to be screened off from the qualification arena, despite being part of the same space. There is potential for worldbeating here, however, this year's competition was held at the same time as the Roma Archery Trophy stage of the indoor World Series, which limited the attendance of the world's elite. Fixture clashing aside, the competition saw many of the best in Germany and across Europe take part, along with a single elite Korean archer: veteran Gu Dong Nam, who finished in the top eight in the indoor series finals in Las Vegas in 2019. A previous lone Korean, minor Olympic legend Jang Yong-Ho, competed and won this same tournament a couple of years back. However, Gu was beaten in the 1/8 match, 6-2, by eventual winner

Heiko Keib, who despite only qualifying in 15th place with 567 maintained consistently high matchplay scores to push through the bracket and eventually to defeat Stephan Arend, also of Germany, in a top-level final. In women's recurve, Dutch international (and occasional Bow columnist) Claire van Dijck finished in the top spot. van Dijck, the second seed, defeated first seed Malgorzata Sobieraj of Poland. The para competition featured an open W1 class with both men and women competing together, this included multiple Paralympic medallists such as Jessica Stretton and David Drahoninsky, who eventually finished third, beating Phoebe Pine by a single point, behind Nathan MacQueen (GBR) and winner Marcel Pavlik, of Slovakia, who dominated the competition. GBR were well represented in the compound competition as well, eventually won by eighth seed Simon Scott, who survived two shootoffs in matchplay to take the win over German Lars Klingner. Susan Corless and Iulia Petra also finished in the top ten. The Berlin Open was well-organised with an improving finals production, and definitely now has the venue to become one of the great tournaments on the circuit, with Berlin a magnet for tourists. If they can find the right spot on the calendar, the sky is the limit. 

t was a weekend to remember. Now in its second year, and with full headline sponsorship from the huge American manufacturer T.R.U.Ball / Axcel. Hitting 600 archers, it has become the third largest indoor event after Vegas and Nimes – and with almost infinite space to expand across the cavernous Fieri di Roma arena. The Eternal City was finally paid a visit by Brady Ellison, who had skipped the first two stages of the World Series after his ridiculously successful outdoor summer season. Also present was defending champion Crispin Duenas, a mighty presence indoors. Both Ellison and Duenas made the last eight, but both were unexpectedly defeated by a wellknown name bursting out of many years of mid-table obscurity: the 2004 Olympic individual champion Marco Galiazzo. It would always be a bad idea to write off a man with three Olympic medals – two of them gold – but it's probably fair to say Marco hasn't really been at the business end of the international circuit much since London 2012, although he was part of the Italian team that

took the World Championship title back in 2017. But in 2019 he won the World Military Games in China, an outdoor event that saw him beat compatriot and European Games champion Mario Nespoli and Korean hotshot Lee Woo Seok. Indoors, he strung together four 30s to take down top seed Duenas and dropped just two points in five sets to push out an almost-equally in-form Ellison in the final. At 36 years of age, he has unexpectedly found a groove this year, and it goes once again to show that writing off older archers is a terrible idea. “I took advantage of some mistakes of my opponent,” said Galiazzo, lugubriously, afterwards. “I am very happy to have won here in Rome. It’s always a pleasure to win in your own country and on live television.” The women's recurve division featured four Korean pros from the Hyundai Mobis team, all of whom strolled to the last eight, but their seeding was split by European Games champion Tatiana Andreoli, still just 21, who ended up taking the biggest fish of all, world number one Kang Chae Young, to a shootoff.

heating the bow before stringing it them individually many times until they achieve their characteristic shapes. All materials used in bow making are constantly bent and shaped over a charcoal fire until the bowmaker is happy and deems them suitable for gluing. When all materials are finally glued together, they will be bound with a rope and dried for 20 days at a temperature of 25-30°C; this is followed by further manual shaping. Each bow will come out as a unique piece; the bow grip and the thumb ring will be personalised to user’s hand and thumb. To complete one product, the bowmaker will touch the bow more than 3700 times over those four months. It will take more than ten days for a fletcher to complete one arrow – a 50 step process. Traditional bow making demands for a great set of skills, experience, patience and physical strength. As an traditional artisanal skill, despite being protected as an intangible cultural asset by the Korean government, it is a correspondingly rare career: there are now only ten active bowmakers in South Korea today.

the 'body stringing' method the bow’s shape and learn to treat it with care so it doesn’t break. There are two ways of stringing the bow: first, by using your body, second by using a gungchang – a specialist fixture that assists in stringing and is used by most archers. All archers will store their bows in thermal boxes, either at the clubhouse or in their home. Most will have a wooden thermal box at home because they would often need to prepare their bow for shooting at a competition, where there

would be no space or time to do so. These boxes are often made by archers themselves and are known as jum hwa jang. Temperatures at which the bows are kept vary from 21-25°C. The archer will first take the bow out and unwrap it; the bow will be bent outwards into a crescent shape. Archers use a portable electric hot plate and will hold the bow over its heat to soften the glue. The archer will listen to the sound of the bow and look for a certain

Bow Preparation Since bow making is a lengthy seasonal process, I did not have the opportunity to observe it in full on this trip. I was however treated to a personal demonstration of bow preparation by my friend and bow maker, Bo Hyun Yoon, who has a couple of decades of shooting and bow making under his belt. Recurve archers should never again complain about having to set up their rig, because it takes on average around forty minutes to prepare a traditional bow for shooting. A novice may spend up to an hour, because they will have to get acquainted with
