The relationship between the level of technique skills and performance in small-sided games in U12 football players
Kabelák, Tomáš ; Kokštejn, Jakub (advisor) ; Buzek, Mario (referee)
Topic: The relationship between the level of technique skills and performance in small- sided games in U12 football players. Objective: To find the diferences in success of defeating an opponent in small-sided games between three groups of players (devided according to level of technical mastery of defeating an opponent in technical exercise without an opponent). To find the relationship between level of technique skill in defeating an opponent and success of defeating an opponent in real condition in small-sided games in U12 football players. Methods: Evaluation was based on our test. Small-sided games were used for evaluation of success of defeating an opponent in situations 1 on 1. Methods of direct and indirect assessment with help of video were used for assessment of the test as well as the small-sided games. Results: Significant effect size differences were found between groups of players in small-sided games in % success of defeating an opponent and % success of keeping the ball in attempt to defeating an opponent. The results suggests that players with higher level of technical skills in defeating an opponent are more successful in defeating an opponent in real game situations. Nevertheless, the statistically significant results weren't found. Key words: Football, motor skills, small-sided...

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 =...

Chuda, David ; Kokštejn, Jakub (advisor) ; Malý, Tomáš (referee)
Title: Effect of small side games and interval running on level of selected fitness parameters for soccer players Objectives: Determining the effect of small side games and interval running with / without balls on selected fitness parameters for soccer players (U17 and U19). Methods: Measurement method, Intervention method. The group observed contained players aged 15 to 18. Total number of players was 36. From U19 team it was nineteen players and from U17 team it was seventeen players. In the end we counted to the results 15 players from U17 and 13 players from U19.Used tests: Yo - Yo intermittent recover test level 2, Ilinois test without dribling ball, Ilinois test with dribling ball, Myotest and 20m sprint. The data were gathered to Microsoft excel programme. Statistic analysis was done in IBM SPSS Statistics 24 software. Results: Both intervention groups of footballers (U17 + U19) experienced a significant improvement in aerobic fitness (YYIR2, p <0.05, r >= 0.58-0.63). In the IR group there was a significant improvement in the agility test (p <0.05; r = 0.54). Both groups recorded significant improvements in the CMJ Force parameter (p> 0.05; r = 0.34, r = 0.36). However, no significant improvement was noted in the other power performance parameters. Both groups experienced an improvement in...
