Čmeľ, Martin ; Vorálek, Rostislav (advisor) ; Petružela, Jan (referee)
Title: Developing the explosive strength of the lower extremities of the players of the extra league team in volleyball. Subject: Measuring the jump height of twelve players of the extra league team. Objectives: Measure to see if it is possible, by systematically training the explosive strength of the lower extremities, to increase the jump height for volleyball players after a period of three months. Results: To compare the results of each single measurement with the first measurement performed prior to systematic training of the explosive strength of the lower extremities Key words: Development, explosive strenght, lower extremities, player, volleyball, team.

Using kettlebell swing to increase the explosive strength of the lower limbs on volleyball players
JEŘÁBKOVÁ, Andrea
This Bachelor thesis deals with question of training explosive power of lower limbs by volleyball players. Because of high important, jump is the main part of performance in volleyball, it´s necessary to keep development of explosive power in training thoroughly. In development of this power is used technique of deep squat with a barbell, in which upper limbs are inactive. However for jump, upper limbs are used as one of necessary parts so for this research kettlebell swing technique was used, as its involve upper limbs and the body generally. The theoretical part of this thesis contains a description of muscular power, its meaning and what affects it. The part also contains description of volleyball jump, its performing during the game and its overall contribution to player´s performance. In this part is description of kettlebell swing technique, why it´s suited to increasing explosive power of lower limbs and how its affect organism. Furthermore, there is a description of its correct execution and muscle involvement during the exercise. In the same way is written a chapter about the technique of deep squat with a barbell. Practical part was made as a qualitative research by using of six case casuistry, which contains input and output kinesiological analysis, tests of postural stabilization and postural reactibility by Kolář, tests of shortened muscles by Janda and tests of explosive power (K-test, absolute reach and standing long jump). In this part are also described methods, carrying out and results of examinations and tests that have been conducted in this research. Research takes three months, during which, tested subjects practiced particular techniques and then by their own training plans ordered by teams. In results there are described individual case casuistry, and at the end of each case casuistry is evaluation of each subject. In overall evaluation are compared results of tests of explosive power and other examination of all subjects. Results shows importance of correct execution and correct activation of deep stabilization system. During the research two subject were injured so their exercises and final results was affected. This Bachelor thesis could be used as a source of information for coaches or players, not only, volleyball and also it could be used for rehabilitation after injuries of lower limbs. Thanks to moves made during kettlebell swing, which comes from hip joints, aren´t knee joints loaded so much. After operations and necessary immobility occurs muscular atrophy, decentered position of lower limbs root joints and instability. Due this reason kettlebell swing technique could be used to increase muscle strength of lower limbs after injuries of meniscus, anterior cruciate ligament, joint ankle distortions and various traumatic injuries of lower limbs.

Optimization of warm-up before strength-power training
Čaklošová, Karolína ; Jebavý, Radim (advisor) ; Červinka, Pavel (referee)
Title: Optimization of warm-up before speed-strenght loading Objectives: The aim of this work is to compare three variants of warming up and to determine the most appropriate one before speed-strenght loading. Methods: The test group consisted of 15 male students of the Faculty of Physical Education and Sport at The Charles University at the age of 22 -26 years. The tested subjects underwent 4 tests within 4 weeks. The first test was used to determine the 1 RM bench press and leg-press, the results of which we needed for the proper determination of the weights for the following protocols. The other three measurement protocols include three warm-up (base, a speed-strenght and toning), followed by a test of explosive strength in arms and legs. Countermovement vertical jump height with arm swing was used for legs testing and medicine ball shoot-up in supine position was used for arms testing. Results: This research shows that best results in the countermovement vertical jump height with arm swing were achieved after the speed-power warm-up. The best results in medicine ball shoot-up in supine position were achieved after the basic warm up, but results are not statistically significant for these testing. Keywords: Warm-up, dynamic stretching, speed-force loading, toning, explosive force, testing

Pešek, Adam ; Pavelka, Radim (advisor) ; Zdobinský, Adam (referee)
Title: Testing and developing explosive power of young karate athletes of discipline kata Objectives: The objective of this bachelor thesis is to determine the effect of the intervention conditioning program on explosive power of young karate athletes of discipline kata. Methods: Testing was performed using four motor tests. The data were processed using basic statistical method and Wilcoxon pair test. Results: Intervention conditioning program had a positive effect on increasing the level of explosive power in the tested experimental group. Keywords: karate, kata, explosive power, testing, developing, kids

Influence of body composition on explosive power of elite judokas
Turek, Miroslav ; Pavelka, Radim (advisor) ; Smolík, Petr (referee)
Title: Influence of body composition on explosive power of elite judokas Objectives: The main aim of the thesis is to discover whether the body composition effects the explosive power of elite judokas. The work also depicts the development of the explosive power during training and describes how to measure and compare the explosive power in upper limbs of a selected group of professional judo fighters within a general and specific exercise. Another aim of the thesis is to determine which weight categories are characterized by the biggest explosive power in upper limbs and whether this power mounts with the increasing weight category. Methods: The thesis has an empirical and theoreticalcharacter. Methods of data collecting, analysis of technical literature in the field of general sports preparation and judo training were used for the research. For the evaluation, the basic statistic methods and Spearman correlative coefficient were applied. Results: The results of the thesis point out the fact that the explosive power doesn't depend on the amount of active substance in the body of a contestant. The best results in the amount of explosive power from the testing exercises were achieved by the individuals within the weight category up to 90 kg, 81 kg and 100 kg. It has also been affirmed that the...
