Comparison of explosive power in elite youth soccer players.
 Horizral, Peter ; Bujnovský, David (advisor) ; Vampola, Jindřich (referee)
Title: Comparison of explosive power in elite youth soccer players Objective: The objective of this thesis was to determine the level of difference in selected parameters of the explosive strength of the lower limbs of elite youth soccer players between the age categories U14 and U15. Methods: The research set of this diploma thesis consisted of a total of 39 elite youth football players in the age category U15 and U14, who at the time of the test were players of the highest domestic football competition. The research group consisted of players of all playing positions (goalkeeper, defender, midfielder, forward). To analyze selected parameters of the explosive power of the lower limbs, a total of three types of vertical jump were used in laboratory conditions: vertical jump from a squat (English "squat jump"; SJ), vertical jump without arm swing (English "counter-movement jump; CMJ) and jump long jump ("broad jump" in English; BJ). The following parameters were analyzed: vertical jump height (cm) and long jump length (cm). Results: Statistical analysis found significant differences (p < 0.01) between monitored parameters. The analysis found a significant difference (p < 0.01) between squat vertical jump (SJ) and non-arm swing vertical jump (CMJ) height between the U15 and U14 groups. Older U15...

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...
