Title: The comparison and identification of strength abilities among elite footballers depending on ontogenesis. Objectives: The aim of this work is to compare the explosive power of the lower limbs and the isokinetic power of the knee extensor and knee flexor of elite football players in cathegories U16, U18 and U21 of the club SK Slavia Praha. Method: Our work is based on using the comparative method. The respective method of comparison is used in the section related to results., in which we compare the achieved strenght abilities of each category in the vertical jump tests and the isokinetic dynamometer tests. The research team were young players (n46) from three age-old categories U16 (15 players), U19 (17 players) and U21 (14 players). The results: The result of the study is a finding that the performance of the individual categories in the vertical jump tests within the maximum power achieved is very balanced, but the best average results in the maximum height were found at U21 team. The order of the individual categories is not the same as the maximum height achieved in the vertical jump. Another finding is that for U21 players compared to younger categories, we observe weaker achievements with greater performance differences between between the muscle groups of flexor and the knee...
