Pšenková, Barbora ; Feher, Jan (advisor) ; Mejsnarová, Linda (referee)
Author: Barbora Pšenková Title: Application of the plyometric method to develop maximum sprint speed Objectives: The aim of this thesis is to create a comprehensive literature search in the field of maximum speed development using plyometric method, followed by compiling a set of plyometric exercises and designing a plyometric training plan. Methods: The method of this work is literature search. Results: Based on the literature search, the theoretical foundations related to maximum speed and plyometrics were analyzed. The results of the literature search confirmed that plyometric training has a positive effect on maximum speed. Furthermore, the principles of creating and applying plyometric training were analyzed, leading to the compilation of a set of twelve plyometric exercises. These exercises were subsequently incorporated into an illustrative training plan, which, after customization according to the individual needs of the athlete, can be suitable for implementation in training practice. Keywords: plyometrics, strech-shortening cycle, speed training, sprint, maximum speed, performance optimization, training plan

Větrovský, Lukáš ; Feher, Jan (advisor) ; Mejsnarová, Linda (referee)
Title: Analysis of the acceleracion phase of a short hurdle sprint Objectives The objective of this bachelor's thesis was to familiarize the reader with the issue of short hurdle sprints, with an emphasis on data analysis concerning the acceleration phase obtained from measurements on subjects from the adult, junior, and youth categories. Subsequently, from the evaluated data, the aim was to formulate conclusions applicable in practice for both coaches and the athletes themselves. Methods: For obtaining data, the Optojump measurement device was used together with video recordings from the first and second hurdles and the freely accessible computer program Kinovea. The data obtained from the Optojump device was transferred to Microsoft Excel. Subsequent graphs were also created in this program. The analysis was based on the professional literature, primarily (Pollit 2018) and Walker (2019), and involved comparing the data from the measurements of individual participants with each other. Results: From the results of the measurements and the professional literature, we found in the subsequent discussion that most of the tested hurdlers chose the eight-step strategy during the approach. In contrast, elite athletes increasingly practice the seven-step strategy during the approach, but this does not...

Changes in biomechanical parameters of the running stride during model training of a special pace 800m runner (in the preparatory and competition period)
Petrásková, Veronika ; Hojka, Vladimír (advisor) ; Feher, Jan (referee)
Title: Changes in biomechanical parameters of the running stride during model training of a special pace 800 m runner (in the preparatory and competition period) Objectives: The aim of this pilot study was to determine the dynamics of changes in selected biomechanical parameters and then to compare these changes in probands over a 2- month period based on baseline and outcome measurements. Methods: The measurements were performed on three probands, each proband representing a different type of runner (novice athlete, recreational athlete, performance athlete in the national under-23 team). Qualitative analyses with the Optojump device were used. The research was carried out in a pressurized hall in Strahov on an indoor 200 m track in two measurements. The first measurement represented the end of the preparation period and the second the competition period. The probands completed the so-called model training (300 m and 200 m) at a special pace with a one-minute break between sections. During the selected sections, biomechanical parameters were collected by Optojump equipment on an indoor 200 m track in 10 m corridors. Results: Proband 1 improved by 3.1 s over 300 m and by 2.1 s over 200 m in the output measurements of the model training. This improvement was reflected in a 0.006 s reduction in...

Using heart rate variability as a tool in the training process and optimizing the effect of training load
Treglerová, Michaela ; Feher, Jan (advisor) ; Kaplan, Aleš (referee)
This thesis focuses on heart rate variability (HRV) and how measuring, evaluating and working with data collected through the my Sasy mobile app can affect athlete performance. If training is modified according to the body's response to load, it can lead to more efficient performance gains, correct timing of more difficult training and control of overload or overtraining. If training is well planned and the principles of progressive loading during the macrocycle are followed, it is possible to obtain benefit by means of HRV, which reflects the state of the organism in relation to the autonomic nervous system (parasympathetic and sympathetic). If the individual is insufficiently compensated for the next load in the context of the training process, sympathetic activity will predominate and thus the following training unit would not have the desired effect (adaptive changes of the organism). This could lead to overload or overtraining in the long term. Title: Using heart rate variability as a tool in the training process and optimizing the effect of training load Objectives: The aim of the study was to investigate the applicability of monitoring heart rate variability in training of athletes (combined athletes/ hurdlers/throwers). Furthermore, its influence on performance when adjusting the load...

Evaluation of speed limits on non elite soccer players
Havránek, Jan ; Kaplan, Aleš (advisor) ; Feher, Jan (referee)
Title of the bachelor's thesis: Evalution of speed limits on non elite soccer players Processed by: Jan Havránek Supervisor of the bachelor's thesis: doc. PhDr. Mgr. Aleš Kaplan, MBA, Ph.D. Objectives of the thesis: The aim of this thesis is to monitor and subsequently interpret the results of tests focused on speed abilities in a selected group of non elite football players. Methodology: Testing of speed parameters was conducted on semi-professional football players who play in the ČFL, which is the 3rd Czech league. The evaluation itself was based on the results of six simple tests. These tests included three tests for linear speed: a 5-meter sprint, a 10-meter sprint, and a 20-meter sprint. There were two agility tests: the K-test and the 505 test. And the final test focused on lower limb explosive power: the vertical jump. The results section is then divided into two chapters. The first chapter compares the results of the pre-test and post-test. The second chapter focuses on evaluating speed abilities from the perspective of player positions. Results of the thesis: When comparing the results between the pre-test and post-test, there were no significantly large differences that would allow us to say that there was a development of speed abilities as a result of the testing. From the second part...

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

Hlaváčová, Tereza ; Červinka, Pavel (advisor) ; Feher, Jan (referee)
Title: Stress fractures in endurance runners and their causes Objectives: The objective of this bachelor thesis is to identify possible corelation between stress fractures of Czech female endurance runners and their menstrual cycle irregularities, changes in training intensity, reduced energetic intake as well as changes in body regeneration. Methods: Qualitative research was carried out using the survey method with means of non-standardised, anonymous questionnaire. The results were further processed and evaluated using MS Word and MS Excel applications. Results: The results of the research led to the conclusion that a corelation can be detected between stress fractures of female endurance runners and their menstrual cycle irregularities, changes in training intensity, reduced energetic intake and impaired regeneration. The highest degree of co- occurrence was observed with increased training intensity. The next most common connection to stress fractures was found with menstrual cycle irregularities, followed by changes in body regenerations and decreased energy intake. Keywords: Endurance running, female runner, stress fracture, menstrual cycle, the female athlete triad
