Statistical Models of Success of Various Techniques of Rugby Kicking
Vrbacká, Kateřina ; Votavová, Helena (referee) ; Bednář, Josef (advisor)
This bachelor thesis is dealing with the testing of statistical hypothesis and their practical use. We model the success of rugby kicking and analyze the dominant factors (ball position, kicking technique, player) and their interactions. We will use some mathematical terms such as chi-square test of independence and logistic regression. The final model will be processed by software MINITAB. The outcome from this thesis will be the exact description of this situation.

The impact of fatigue on the kick accuracy of young soccer players
Ižovská, Jana ; Malý, Tomáš (advisor) ; Zahálka, František (referee)
Title: The impact of fatigue on the kick accuracy of young soccer players Objectives: Identify the relationship of fatigue and the kick accuracy of young soccer players. Methods: The study group consists of 20 players in the age between 17 and 22, who are actually operating on league level in the reserve of elite soccer club. Before loading, the players had 3 attempts of shooting into the middle of the goal by dominant and non-dominant leg. After loading, they had 3 attempts of shooting into the middle of the goal too, but only by dominant leg. We measured the speed and the accuracy of kicks before loading and after the maximum load. Results: The results of work give information about the impact of fatigue on the kick speed and accuracy of young soccer players. It has been found that after the impact of loading the soccer players had worse results in the studied parameters. Keywords: fatigue, kick, loading, skill, soccer

Comparative analysis of selected soccer kicks
Řebíček, Pavel ; Kračmar, Bronislav (advisor) ; Buzek, Mario (referee)
Title: Comparative analysis of selected soccer kicks Objectives: The main objective of the study is to characterize the involvement of selected muscles during soccer kicks by time and space and subsequent comparison with specific exercises with expander by EMG measurement. Methods: The study has a character of a case study, comparative analysis of relative timing of movement and activity of selected muscles during soccer kicks by surface poly-electro-myographical analysis and kinematic analysis. Results: Timing of muscles involvement during soccer kicks is different than timing of muscles involvement during exercise with expander. Keywords: EMG, soccer, kick, muscles, activation

Influencing Shooting Speed in Football
Čáp, Ondřej ; Jebavý, Radim (advisor) ; Hojka, Vladimír (referee)
Title: Influencing the shooting speed in football Objectives: The aim of my thesis was to record, evaluate changes and verify the effectiveness of the implemented intervention during the reference period in the development of shooting speed together with a rebound ability in a long jump in a football team which is operating in the 5th highest football competition in Germany. Methods: Quantitative research was carried out in the form of motor testing of a football team from a selected foreign football league during the autumn part of the competition. Two tests were selected to determine the development of the explosive force of the lower limbs. It was a specific test of the explosive force of the lower limbs - a kick from a one-step rhythm and a test of the general explosive force of lower limbs - jump. It was a so-called cross over study. Team was divided in two groups, where group A was doing implemented intervention in a different part of reference period than group B. Results: Based on the analysis of descriptive statistics, there was an increase in the statistics in the long jump and a decrease in the statistics in both monitored groups, while group A has the observations with the greatest improvement, but in the group B can be seen mostly an improvement across the whole group. For the second...

Strength as a determinant of kick speed of young soccer players.
Ižovská, Jana ; Malý, Tomáš (advisor) ; Zahálka, František (referee)
Title: Strength as a determinant of kick speed of young soccer players. Objectives: Identify the relationship of strength of extensors and flexors of knee and the kick speed and accuracy of young soccer players. Methods: The study group consists of 20 players in the age between 20-25 years (22,45±1,12 years) league level engaged in the provision of an elite soccer club. The players passed the tests of strength abilities week before field testing of kick speed and accuracy. Strength extensors and flexors of knee were measured in laboratory conditions at three different stages of the angular velocity of the dominant and nondominant lower leg. After week the players completed three shots on goal by preferred and non-preferred leg, where we measured the speed and accuracy of kick. Results: The results of work submit information about relationship between the strength of extensors and flexors of knee and the kick speed and accuracy depending on the degree of angular velocity. It has been found moderate - strong correlation between conditionings depending on the different degrees of angular speed of the movement. Keywords: accuracy, kick, skill, soccer, speed, strength
