TRANSITIONING FROM CLUB TO NATIONAL TEAM; CHALLENGES & SUGGESTIONS FOR PLAYER HEALTH & PERFORMANCE FEATURE / ALAN McCALL1,2, GARY O’DRISCOLL1, GUILHERME PASSOS-RAMOS3, MARK JONES2, 1 Arsenal Football Club, 2 Football Australia, 3 Confederação Brasileira de Futebol FABIAN EHRMANN2, ROB DUFFIELD2 Transitioning from club to national team (and back) The transition from club to national team is an ongoing challenge for medical and science staff (referred to herein as ‘performance staff’) from both club and national team settings, to protect player health and optimise performance. The typical football calendar year includes several international periods where players can be called-up by their national teams to compete in training camps and matches, including friendlies, competitive qualifiers and/ or major international tournaments. During the competitive club seasons for both men’s and women’s senior top-level football, there are usually four to five international periods with around two to four matches over approximately 10 days. Coinciding with most leagues offseasons, there are also major international tournaments that rotate every couple of years, lasting up to approximately six weeks (e.g. FIFA World Cup UEFA European Championships, CONMEBOL Copa America, AFC Asia Cup, CAF African Cup of Nations and CONCACAF Gold Cup). These interruptions can require all or some of the following: short or extensive travel, exposure to different climatic conditions (cold, heat, altitude etc), unfamiliar environments and support (hotels, facilities, nutrition), varying types of training schedules and structures,
increased match volume and demands with players potentially playing in different positions and in new team dynamics. Thus, for those players selected to play international football, there are several periods during the year where their ‘normal’ routine of training and match-play with their club teams, as well as their day to day / week to week lifestyles (including family time, social circles etc) are interrupted. This may happen sometimes quite abruptly i.e. leaving from playing a club match directly to a national team and vice versa: aka, the ‘transition’. Therefore, it is clearly of interest for us as performance staff of both club and national teams to work together to optimise health and performance outcomes for individual players and collectively for our teams (Buchheit and Dupont, 2018). What are the changes in training load and structure following the ‘transition’? Alterations to the ‘normal’ weekly training structure is one of the biggest changes that players transitioning from club to national team (and back) face. This represents one change that is within our scope as performance staff to monitor (at least some aspects) and have some ability to act upon or at least provide some recommendations to

players and to coaching staff. Changes can be seen in the training schedule (e.g. frequency, duration etc), training focus (e.g. switching focus from physical, technical/tactical etc) and the type of training performed (e.g. intensity, specific exercises, drills etc). While our own experience and data within our own teams helps guide us as to what changes we might expect, the football landscape is ever changing. With players, coaches and performance staff often moving to other teams coupled with the very limited scientific evidence that can give us any clear indications of what happens following these ‘transitions’, this proves to be quite a challenge. Of the scarce scientific evidence that does exist describing these changes in training for transitioning players, the majority shows only the transition from club to national team and not when players return to their clubs after national duty. The existing research is also mainly from the same national federation and therefore, generalising this to all club to national team transitions is not possible. To give the reader an idea of what does exist, some of the current research group have followed the same men’s and women’s senior national team over multiple consecutive major international competitions (Noor et al., 2019 and unpublished
