Difference of biomechanical parameters in individual categories in javelin throw
Krejnusová, Tereza ; Feher, Jan (advisor) ; Hojka, Vladimír (referee)
Title: Difference of biomechanical parameters in individual categories in javelin throw Objectives: The aim of this work is to determine whether the biomechanical parameters in javelin throw are different between age categories and gender categories. At the same time, this work deals with how much influence the individual parameters affect the throw distance and whether these ratios are the same or different for each category. Methods: During the research, kinematic analysis and video analysis using the Kinovea program were used. Statistical methods such as ANOVA, Tukey's post hoc analysis and hierarchical regression analysis were also used. Results: It was found that of the measured parameters, the value of 8 parameters differs between at least two categories. Only 2 parameters gave an insignificant result, so there are no different values between the categories. Furthermore, it was found that for 3 categories, the net distance has the greatest effect on the rate of estimation. The other selected parameters are only partially identical and there are some differences between the categories.. Keywords: javelin throw, biomechanical parameters, difference, category, ANOVA, hierarchical analysis

Biomechanical parameters affecting performance in javelin throw - literary research
Krejnusová, Tereza ; Čermák, Filip (advisor) ; Vindušková, Jitka (referee)
Title: Biomechanical parameters affecting performance in javelin throw - literary research Objectives: The main aim of this work is to study scientific and professional publications and articles concerning biomechanical analysis of javelin throw. From these sources find out which parameters affecting performance are measured in biomechanical analysis. Another objective is to determine the frequency of these parameters and other aspects that could affect measurement results. Methods: The bachelor thesis is processed by the method of literary research from available foreign sources. The research part summarizes all the theoretical background and findings that deal with the basic concepts of biomechanics and technique of javelin throw. Comparison was used to compare scientific articles. Results: Based on the processing the available sources, a comprehensive overview of the issue of javelin throw biomechanics was created. This work describes parameters that influence performance and compares results of mentioned authors. Other aspects have been identified that could affect analysis results such as gender, performance class, opportunity, or the type of analysis. Keywords: javelin throw, biomechanics, technique, effect on performance, parameters
