Vyhnálek, Vojtěch ; Gryc, Tomáš (advisor) ; Jurková, Kateřina (referee)
Title: Evaluation, comparison and relationships of selected strength parameters of lower limbs and trunk in basketball players Objectives: The objective of this thesis is to evaluate the relationships between the selected forces trunk parameters and selected strength parameters of the lower limbs. Eight probands aged 33-45 who play second grade Prague championship in basketball were tested. Methods: 8 basketball players participated in the experiment. Flexion and extension strength in the knee joint was recorded with a Cybex Humac Norm isokinetic dynamometer at an angular velocity of 60ř·s-1. The same device was used to determine the strength of the trunk in rotation. The ForceFrame™ device was used to diagnose abduction, adduction at the hip, and internal and external rotation at the shoulder. The measurements were one-time. Selected relationships were interpreted using Pearson's correlation coefficient and paired t-test. Results: In this work, significant (p <0,05) relationships between the strength parameters of the trunk and the lower limb were demonstrated. Strength differences between the right and left sides were not statistically significant. The results suggest that typical relationships between strength parameters emerge in amateur level basketball players, but it is a question for the...

The effect of menstrual cycle and cortisol and testosteron levels on strenght performance in female athletes
Novotná, Kateřina ; Heller, Jan (advisor) ; Pěkný, Martin (referee)
This study provides a comprehensive insight into the physiological and hormonal changes in female athletes during the menstrual cycle and their impact on performance training and recovery. It covers an overview of menstrual cycle physiology, the effects of steroid hormones on the female reproductive system, cortisol secretion examination, and the role of testosterone in female physiology. Furthermore, it analyzes the influence of individual menstrual cycle phases on the strength capabilities of female athletes and studies the relationship between cortisol and testosterone secretion and these abilities. It discusses the influence of the follicular phase on performance in the Wingate test, negative correlation between cortisol concentration and female athletes' strength performance, and differences in maximum performance between athletes with regular and irregular cycles. It highlights general limitations of research on women that need to be considered. Overall, this work contributes to the discussion on the relationship between hormonal changes and strength performance in female athletes, with potential future applications in training and sports performance. KEY WORDS menstrual cycle, hormones, strength capabilities, cortisol, testosterone, physical exertion

Horizral, Peter ; Bujnovský, David (advisor) ; Vampola, Jindřich (referee)
Title: Comparison of explosive power in elite youth soccer players Objective: The objective of this thesis was to determine the level of difference in selected parameters of the explosive strength of the lower limbs of elite youth soccer players between the age categories U14 and U15. Methods: The research set of this diploma thesis consisted of a total of 39 elite youth football players in the age category U15 and U14, who at the time of the test were players of the highest domestic football competition. The research group consisted of players of all playing positions (goalkeeper, defender, midfielder, forward). To analyze selected parameters of the explosive power of the lower limbs, a total of three types of vertical jump were used in laboratory conditions: vertical jump from a squat (English "squat jump"; SJ), vertical jump without arm swing (English "counter-movement jump; CMJ) and jump long jump ("broad jump" in English; BJ). The following parameters were analyzed: vertical jump height (cm) and long jump length (cm). Results: Statistical analysis found significant differences (p < 0.01) between monitored parameters. The analysis found a significant difference (p < 0.01) between squat vertical jump (SJ) and non-arm swing vertical jump (CMJ) height between the U15 and U14 groups. Older U15...

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.
