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...

Jiskra, Jan ; Kokštejn, Jakub (advisor) ; Malý, Tomáš (referee)
Title: Influence of small side games and runs on sprint performance and agility in football players. Purpose: The aim of the thesis is to find out the influence of selected movement interventions (small side games versus runs) on sprint performance and agility in elite football players in U14 category during the preseason period. Methods: The 30-meter Sprint was used to rate speed-strength performance. Players have executed 2 sprints at 30m. Sprint time was measured at 5, 10 and 30m. Agility tests included: test 505 and three-step test. Players also have executed 2 tries (one of each leg). A set of photocells (Alge Timing GmbH, Lustenau, Austria) was used to measure the time of all tests. Results: Both groups significantly improved in the three-step test (p <0.05; r> 0.5). The SSG group, after a two-month intervention, significantly deteriorated in the sprint to 5, 10 and 30m (r = 0.38 - 0.69). The race group did not significantly improve in sprints at 5, 10 and 30m. In the agility test, we saw a significant improvement only in the Run groups and only on the left leg (r = 0.42). Based on the findings, we believe that the training units of the linear speed and speed with the change of direction maintain the level of player's speed during the season. Therefore, I recommend that they should appear in...

Horák, Lukáš ; Musálek, Martin (advisor) ; Kokštejn, Jakub (referee)
Title: Frequency of normal weight obese preschool children and its physical fitness - selected populations of children from 6 Prague kindergartens. Objectives: The goal of this thesis is to find out the occurence and physical fitness of preschool age children with normal weight obese and compare it with physical fitness of normal weight non-obese preschool children and children with overweight and obese. Methods: Observation is the main method used in this thesis (regarding to title). We analysed 289 preschool aged children and chose BMI index in the range of 25th to 80th percentil, according to Vignerova at al. (2006) along with values of each skinfold higher then 85th percentil according to Bláha et al. (1990), to identify normal weight obese children. Physical fitness was based on several tests: multistage 20 metre shuttle run, standing long jump, sit-ups, sit- and-reach, throw ball with alternative hands. To analyse all the facts and get results we used descriptive statistics, tests of normaltity and ANOVA. Results: We identified n = 12 normal weight obese children (4,15 %) from all participating children. Results of research showed us that normal weight obese children were worse than normal weight non-obese children by 5,80 %, respectively by 4,76 %. Children that were overweight and obese had...

Relationship between the maximum isokinetic strength and one repetition maximum leg press in soccer players U15- U17
Baratynskyy, Ivan ; Šťastný, Petr (advisor) ; Kokštejn, Jakub (referee)
Title: Relationship between the maximum isokinetic strength and one repetition maximum leg press in soccer players U15- U17. Objectives: Determine whether it exist dependence between maximum strength leg press and isokinetics of the lower limbs of football players. Methods: In my work I used methods of measurement and comparison. The measurements were made on the leg press and the Cybex dynamometer. On the leg press, the maximum force was examined and the Cybex dynamometer measured flexing and extension of knee joint at different speeds. Comparison of results was done in Excel using Person's correlation coefficient. Results: My first hypothesis that leg-press results will correlate with Cybex results has been confirmed at higher speeds. This fact was confirmed in other studies with similar research. The second hypothesis was based on the relationship of the h / q ratio and its correlation with the results achieved on the Cybex dynamometer. This hypothesis was not confirmed and the values achieved were very low. Key words: Strength capabilities, leg-press, Cybex, repetition maximum

Kroupa, Jakub ; Malý, Tomáš (advisor) ; Kokštejn, Jakub (referee)
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...

Influence of acceleration abilities on performance in agility tests (speed of change of direction of movement)
Hrubý, Jakub ; Hojka, Vladimír (advisor) ; Kokštejn, Jakub (referee)
Name: Influence of acceleration abilities on performance in agility tests (speed of change of direction of movement) Objectives: The main goal of this work is to determine the level of agility performance with acceleration and maximum speed for football players of different age categories. Methods: To solve the problem, I used a correlation analysis. The first measurement was acceleration and peak speed measurement using photocells. The second measurement was focused on performance in change of direction speed. The resulting data from photocell measurements was processed using IBM SPSS statistics 22 and Microsoft Excel. Results: I have found that the greatest impact of the selected COD's tests has an illinois test at r = 0.596 with an almost 100% connection on the acceleration, maximum speed for 16- 17 year old footballers. In addition, it was found that the 505 test had the best connection with the AR_5 test, r = 0.418 with almost 100% acceleration related. The third best result was the arrowhead test, which got r = 0.301, a small correlation value with 90% of the acceleration and maximum speed. The worst result was found in the hexagon test, which had negative r values, ie, an absolutely insignificant correlation. Keywords: football, fitness, speed, COD's, agility, performance structure
