Détermination et variation du profil physique du footballeur de très haut niveau : référence spéciale aux performances athlétiques selon les différents postes de jeu orientant sur la validation d’un test d’agilité

Abstract : This work is dedicated to scientists, coaches and physical trainers as well as athletes involved in elite soccer activity. The scientific results and their practical applications could be used as a basis for the work of scientists as well as football professionals. The first part of this thesis showed that playing positions significantly influence activity profile. Moreover, this study demonstrated that the work/rest ratio observed in elite soccer Italian Serie A championship attained 1/8 and represented a mean work time of 2.2 seconds for an averaged recovery time of 18 seconds. The second part of this thesis, explored the evolution of activity profile and total ball possession during 3 consecutive seasons in the same elite team. This study has showed how for three consecutive seasons the players of successful Serie-A team reduced their distances performed at submaximal speeds, and increased ball possession while maintaining the distances covered at high/maximal speeds. It is suggested that this is due to a better understanding of tactical roles and team organization. The third part of the thesis tended to develop and to valid a specific agility soccer test composed with fundamental soccer tasks which has to be performed as quickly as possible. The validity and repeatability of the test has been demonstrated and it has been applied on a large population of different ages, positions and levels. As a conclusion, this thesis provided new specific results and perspectives that would influence professional soccer athletic conditioning and that provided a new specific test to detect young soccer players.
