Kubešová, Nicola ; Malý, Tomáš (advisor) ; Zahálka, František (referee)
Title: The level and comparison of speed in female soccer players Objectives: The main objective of this study is to determine the level of speed and speed-agility abilities of elite female players of the junior category. And to compare the results within the WU18 category, i.e. between the birth years 2006, 2007 and 2008. The secondary aim is to compare the results between the tested clubs AC Sparta Praha and FK Viktoria Plzeň. Methods: Field testing was used to provide results, which consisted of speed and speed-agility tests standardized in soccer. The test battery included a 10 m sprint with a 5 m intermediate time, a 20 m fly test, a K test and a 505 agility test. The test population was female players under 18 years of age playing for elite academies in the Czech Republic - AC Sparta Praha and FK Viktoria Plzeň. Results: The results of the tests, when comparing the players by year, did not show significantly better results for the oldest players, i.e. players of the year 2006. In most of the tests the players of the year 2007 achieved the fastest values. When comparing the individual tests by year of birth, the 2006 players performed significantly worse than the 2007 players and in a few tests also than the 2008 players. When comparing the teams in terms of league table position, we did not...

Altman, David ; Kokštejn, Jakub (advisor) ; Hojka, Vladimír (referee) ; Hráský, Pavel (referee)
Title: Evaluation strength, speed and agility of elite football players. Objectives: The main aim of this work is to determine the level of strength, speed and agility of elite football players (15-16 years). The secondary aim is then to identify the interrelationships between physical strength, speed and agility. Methods: The main scientific methods of theoretical - empiric character are in field testing and observation. The research group included 31 players Motorlet Praha and 30 players Bohemians Praha 1905 categories U16 and U17. Basic descriptive statistics and correlation and regression analysis were used to evaluate the measured data. Results: Little connection has been found between linear sprinter and agility tests (r = 0.28- 0.40). Very similar pattern has been found between linear sprint performance and maximum limb strength (r = 0.16-0.23) and also between the performance in the agility test and the maximum strength of the lower limbs (r = 0.15-0.18). A significantly better performance in the agility test was discovered among older players (16 years) compared to younger players (15 years). The results show the low level of interaction between selected parameters which play an important role in the game performance of football players. Performance in the agility test seems to be...

Comparison of agility and leg press maximum strength in adolescent soccer players
Nápravník, Pavel ; Šťastný, Petr (advisor) ; Kokštejn, Jakub (referee)
Title: Comparison of the level of agility with maximum force of the lower limbs, measured by using a leg press, for players of football in junior category. Objectives: Comparison of maximum strength of lower limbs measured by the leg press with the performance in agility. Comparison of maximum strength of lower limbs measured by the leg press with performances in the short sprints. Comparison between the individual sprints. Method: The group consisted of 66 measured players aged 15 - 19 years old. The players passed the test throughout the day including the battery tests tanity (height, weight, amount of fat, amount of muscle mass, bone mass, metabolic age, BMI, protein expressed in kilograms, TBW, ICW, ECW, BMR, visceral fat, segmental analysis-muscle mass in kilograms, fat percentage and phase angles-segmental), stability, handgrip (dominant limb + performance), long jump one foot, agility (Arrowhead R and L , Illinois, K-test, Hexagon, 505 R and L), linear speed (5, 10, 20 m run and 20 m flying run), the maximum force of the lower limbs (leg press), anthropometry (the length and width of each of the segments, the fold of skin, the circumference of the thighs, calves and ankles), SJ, Plyo-6 hops, CMJ- free arms, CMJ- fixed arms, Cybex. From this test battery was used data from tests linear speed,...
