Profile of youth footballers as goalkeepers
Zvoníček, Matěj ; Gryc, Tomáš (advisor) ; Bujnovský, David (referee)
Title: Profile of youth footballers as goalkeepers Objectives: The objective of this study was to compare selected parameters of body composition, level of static postural stability and level of lower extremities explosive strength between male and female goalkeepers in soccer and between selected age categories. Methods: A total of 33 male (n = 22) and female (n = 11) soccer goalkeepers participated in the study. They were divided into six test groups based on gender and age category (14-15, 16- 17 and 18-19 years) for performance assessment. These groups were assessed for basic anthropometric data (body height and weight), body composition parameters (% body fat, fat free mass), and level of static postural stability (deviations of the total center of pressure path) in four types of stands (narrow stand open eyes/closed eyes, right/left lower limb stand) and lower extremities explosive strength (jump height, relative force impulse, relative maximum force produced) in four types of jumps (counter movement jump free arms, counter movement jump, squat jump, drop jump). We used a Tanita MC-980MA bioimpedance device (Tanita Corporation, Japan) to assess body composition parameters, a Footscan pressure plates (RSscan International, Belgium) to assess postural stability, and a KISTLER 8611 force plates...

The Creation and the Verification of a Strength Training Program to Develop Jump in a Youth Basketball Team of BK Tigers ČB
POBORSKÁ, Klára
The aim of this bachelor thesis is to design and verify an eight-week strength training plan focused on lower limb strength, which should improve the quality of a vertical leap. The program is added to regular team trainings once a week. A youth team of those born 2006-2007, who play basketball for BK Tigers in České Budějovice, is tested. The testing was implemented in an academic year of winter semester 2019. As an entrance and exit test, a vertical leap at the wall is selected. In the theoretical part of the thesis, a general anatomy and physiology, strength abilities, strength training as well as an issue of children s and basketball strength training are described. The practical part describes an implemented training program and a procedure of measurement. The results and their factual importance were verified through the student s t-test and Cohen s d. Individual results are provided in tables and a chart. The results showed an improvement with a low significance level with an average improvement of a vertical leap 8,18 cm.

The Creation and the Verification of a Training Program to Develop Jump in a Adolescents Volleyball Team VK Jihostroj České Budějovice
VÍTŮ, Sabina
The thesis aimed to the creation and verification of a training program of improvement vertical jump volleyball team VK Jihostroj České Budějovice. It was a kvaziexperiment. It involved ten volleyball players from a youth category and two volleyball players from a men category. Initial testing was performed before a three-month training intervention and then final testing followed. The testing combined two tests made on a reaction platform LEM 10 with ProJump, which is located in the laboratory of stress diagnostics at KTVS in České Budějovice. The first test was the maximizing vertical jump height and the second test was the endurance test, which consisted of three jumps. Another observed aspect is a biological one. The training intervention was incorporated into the normal training plan and took place every Monday and Wednesday. The research has proved that volleyball players had higher measured values of output vertical jump comparing with input values from the entry test because of the training program. The prediction that probands would have average or better results of an output endurance test than the entry test due to the training program was not confirmed. Furthermore, the assumption that probands will achieve average or better results in maximum vertical jump than the given average by LEM 10 with ProJump manual has not been confirmed as well. The correlation between the biological age and the maximum jump, which is evaluated by the correlation coefficient and is greater than |0,4| was confirmed.

The comparison of strength of lower limbs in different ski and snowboard disciplines
Tišer, Kryštof ; Jindra, Matouš (advisor) ; Gnad, Tomáš (referee)
Title: Comparison of explosive strength of lower limbs in different ski and snowboard disciplines. Aims: The aim of this thesis is to compare explosive strength of lower limbs in different ski and snowboard disciplines. Methods: This is an empiric-theoretical thesis. A simple experiment (testing) was used to verify the hypothesis. 6 used sets participated in the quantitative research. Testing was carried out using two standardized tests, broad jump and vertical jump (Sargent jump). In both tests the best of the three trials was evaluated. Results: In two tests for the explosive strength of the lower limbs significant differences in this ability were shown between some ski disciplines and snowboardcross. The best results in both tests were achieved by representatives of alpine skiing which disproved our hypotheses. Only the expectation that ski jumpers would perform better than the nordic combination was fulfilled. Key words: explosive strength, broad jump, vertical jump, skiing, cross country skiing, grass skiing, nordic combination, ski jumping, alpine skiing, snowboardcross

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.
