Varjan, Matej ; Malý, Tomáš (advisor) ; Kokštejn, Jakub (referee)
Title: The level and differences in selected movement abilities and skills in youth soccer players. Objectives: The aim of the thesis is to compare the results of the Skills Tests before and after a short-term test and to determine the influence of exhaustion on the speed and quality of specific football skills of the elite footballers from U15 football team of SK Slavia Praha team. Methods: The research set, consisting of 15 research participants, took two measurements. The Loughborough Soccer Passing Test (LSPT) was taken like a pre-test and post-test (after short-term BUMAZA test). In the result part we applied the analytical method for the results which we obtained from the measured tests. The comparison method was used for comparison of the values of the LSPT test results before and after the stress. Finally, the basic statistical methods helped us to process the measured values. Results: The thesis results provide information about the level of physical abilities and movement skills of the players based on the obtained values of the taken tests. We found out that most players improved their straight time values in the LSPT test measured after the stress. Conversely, the penalty time was increased up to 33,32% which affected the total time. On the contrary, the value of penalization and total...

Title: The effect of a short-term intervention program for development of sprint and agility in soccer players (U16) Author: Bc. Tomáš Chaloupka Head of work: Mgr. Jakub Kokštejn, Ph.D. Objectives: The aim of the thesis is to verify the effectiveness of two different short- term intervention programs in the development of speed-power abilities in young soccer players (U16). Methods: The research sample included soccer players (16 year old; n=22; 15,2±0,3 years) from the highest competitive level in the Czech Republic. For the interventional effect verification we used tests without the ball (sprint on 5, 10 and 30 meters, Illinois Agility Test, Yo-Yo IRT 2, six jump alternately) and with the ball (sprint on 5, 10 and 30 meters, Illinois Agility Test). Data analysis was performed by using IBM SPSS software Statistics 24. Results: Both groups of players improved in the agility test (r = 0.32; r = 0.40), but these improvements were not statistically significant (p = 0.16; p = 0.06). Group 2 (runs) improved in the ball agility test (p = 0.02; r = 0.49). Both groups were improved in a six jump strength test (group 1 p = 0.02; r = 0.51; group 2 p = 0.08; r = 0.32), but in group 2 improvement was not statistically significant. Both groups were improved in Yo-Yo IRT2 speed endurance (group 1 p = 0.09; r =...

Ivasko, Aleš ; Kokštejn, Jakub (advisor) ; Šťastný, Petr (referee)
Title: Relationship between game skills, physical fitness and self-efficacy in footbal players in relation to age. Objectives: Discover the interrelationship of self-efficacy, physical abilities and specific game skills in football players (13 - 19 years). At the same time, the objective is to verify the effect of age on the level of physical abilities, specific game skills and self- efficacy. Methods: The Czech version of the General Self-Efficacy (GSE) standard questionnaire was used to determine the level of self-efficacy. To determine the level of physical abilities and specific game skills, were used to diagnose and compare the level of football players in centers for the education of talented youth. A set of photocells (Alge Timing GmbH, Lustenau, Austria) was used to measure the 20 m sprint time, agility and ball slalom. The basic statistical characteristics (arithmetic mean, standard deviation) will be used to interpret the results. Standardization / normalization of values has been used with the help of Z-points for transferring results so that we can express the level of specific game skills with a single score. The Pearson correlation coefficient was used to evaluate the relationship between self-efficacy and football gaming skills. To evaluate the significance of the differences between...

Urbanec, Matyáš ; Kokštejn, Jakub (advisor) ; Šťastný, Petr (referee)
Title: The level of speed and agility in elite football players (15-17 years). Aim: The main aim of this thesis is to find out the current level of performance in linear speed and agility in elite football players (15-17 years), given the age of the players. At the same time, the aim is to find out the relationship between performance in linear speed tests and agility. Methods: The main scientific method which had a theoretical-empirical character was the observing and testing method. The research team consisted of 30 players FK Motorlet Praha and 32 players Bohemians Prague 1905 categories U16 and U17.

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...

Effect of small side games and runs on performance in sprints and agility in soccer players.
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...
