Strength asymmetries in female soccer players depending on the player's post.
Lisoň, Maroš ; Ižovská, Jana (advisor) ; Šťastný, Petr (referee)
Title: Strength asymmetries of female soccer players according to playing position Objectives: The aim of this diploma thesis was to characterize the unilateral and bilateral asymmetries of knee flexors and extensors in elite football players based on player positions and to define the characteristic isokinetic strength profile for each playing positions. Methods: The research group consisted of 66 female football players who play in the highest czech league. The players completed laboratory testing under the supervision of qualified experts, which took place according to the standard conditions described in the methodological part of this study. In the case of players, we examined the strength asymmetries in the flexors and extensors of the knee and compared them between the 4 basic positions in football. Results: After summing the data from all angular velocities (60ř.s-1 , 180ř.s-1 , 300ř.s-1 ) we found that 33% of our attackers had quadriceps asymmetries above 10%, which was the most of all posts. This is followed by goalkeepers with 28% and midfielders with 25%. The lowest percentage of quadriceps asymmetries was recorded in defenders 22%. Even in the case of hamstrings, we recorded the most asymmetries (> 10%) in attackers, up to 46%. For midfielders and defenders, it was the same result for...
