Šťastný, Daniel ; Pavelka, Radim (advisor) ; Petr, Miroslav (referee)
Title: Optimal conditions of caffeine use and its effect on sports performance Objectives: Based on current scientific knowledge, summarize the effect of caffeine on various aspects of sports performance, and also to determine the optimal conditions for the use of this substance to maximize the ergogenic effect. Methods: Systematic literary research Results: The ideal dose of caffeine to improve athletic performance is in the range of 3- 6 mg/kg, and most preferably in the form of tablets 60 minutes before exercise. This substance has been shown to improve aerobic endurance performance, sprint speed and cognitive function such as accuracy and attention in athletes. Caffeine in trained individuals may also improve anaerobic endurance, maximum and endurance strength, simple reaction time and other cognitive functions, but further studies are needed. . Keywords: sport, supplementation, aspects of performance, conditions of use, stimulation, alkaloids

Skřivan, Tomáš ; Pavelka, Radim (advisor) ; Třebický, Vít (referee)
Tittle: Diagnosis of reaction level of fighters in Thai boxing Objectives: The main aim of this bachelor thesis is to diagnose the level of reaction ability of fighters in Thai boxing, who have been engaged in this combat sport for several years on a professional level. Partial aim of this bachelor thesis is to find out the connection of the diagnosed reaction time with the success of the fighters in the last three years. Methods: In the quantitative research where the Vienna test system- determination test (short form with adaptive input of stimuli) was used for obtaining results. In our case, we investigate selective reaction ability. We compare results of reaction ability with fighting success. The correlation between the reaction time and the success factor is calculated using the correlation coefficient. Results: Based on measurements, made by using the Vienna test system, we found out, that professional Thai boxing fighters, were diagnosed as having a response rate in the main variable as a better average compared to the standard area average of the standard scale. Minor variables came out as a weaker average to below average. We also found, that the most mistakes wrestlers make on acoustic stimuli. Lastly, we disproved the hypothesis that the wrestlers with a better wrestling balance will...

Boháčová, Michaela ; Zdobinský, Adam (advisor) ; Pavelka, Radim (referee)
Title: The development of flexibility and its influence on sports training of judo Objectives: Analysis of the influence of flexibility in sports performance in judo and its appropriate methods of development. Methods: The diploma thesis was processed as a descriptive-analytical work in the form of a critical literary resource search. Results: Based on the literature search, it was found that judo in the main part of the training unit leads to the development of flexibility. It influences the speed of execution of the technique and improves sports performance. Flexibility can be amplified not only by the traditional stretching method, bud also by strength training. However, this is not the case with the development of maximum strength. There is no established test in testing methodology for evaluating flexibility. Keywords: Judo, flexibility, sports performance, resistance training, motor testing, literary research

Rudolf, Jan ; Pavelka, Radim (advisor) ; Zdobinský, Adam (referee)
Title: Acute effect of a warm-up on the force of a punch Objectives: The aim of this diploma thesis is to test whether a warm-up before a performance affects the force of a punch at a sample participants practicing full-contact combat sports. Further goal is to analyze a change in the force of a punch depending on elapsed time after warming up. Methods: Each participant in this experimental study with intra-subject design went through all phases of the measurement, where the force of a punch was tested in four specified times (before a warm-up and then 4, 10 and 25 minutes after the warm-up). Results: No statistically significant effect of a warm-up on the force of a punch was observed, nor was there a statistically significant change in the force of a punch during the time following a warm-up. However, a warm-up did have a significant effect on change in heart rate and body temperature. Keywords: Combat sports, performance, fight, dynamic stretching, explosive power, punch sensor

Čížek, Jakub ; Zdobinský, Adam (advisor) ; Pavelka, Radim (referee)
Title: Analysis and comparison of boxing styles of elite amateur boxers from Cuba and Kazakhstan Objectives: The main goal of this thesis was to find out whether the frequency of use of punching techniques and the distance from which these punching techniques are used are statistically significant for the style of two the most successful countries in amateur boxing. The countries were compared in the use and success of the strikes and compared to their preference for long or medium combat distance. Methods: The method of quantitative observation was used, in which data was obtained by watching video recordings. Part of the matches was evaluated by recording the results manually on paper, the other part in the BORIS program. All data was then transcribed into a Microsoft Excel spreadsheet, where it was also processed. The source for the data were publicly available video recordings from top competitions in 2010-2020. Results: Differences between countries in the monitored indicators are insignificant and boxing styles do not differ much. In the frequency of the use of striking techniques between the rounds, a significant difference was found only between the first and second round of the Kazakhs. In the case of determining the preference for long and medium distance combat between the rounds, there...

Sochor, Jakub ; Zdobinský, Adam (advisor) ; Pavelka, Radim (referee)
Title: Mapping the occurrence of teaching martial arts in physical education at primary schools, secondary schools and grammar schools in Prague. Objective: The goal of the research is to find out how education in P.E. classes reflects the recommendation of framework education programme about education of martial arts, what percentage of clasśes do martial arts take in P.E. and to describe current trends of implementing martial arts to the curriculum or discover the reasons behind not implementing from the P.E. teacher's perspective. Methods: Analysis of literature of the given topic. We chose a survey as a research instrument. Based on previously published survey, which asked about the education of martial arts at a smaller selection of schools in Moravian region (Reguli, Ďurech, Vít, 2007), we created a purposeful survey. The survey was made on a platform service survio.com and distributed via e-mail to individual headmasters. They passed on the survey to P.E. teachers Results: Based on the evaluation of the survey, it was found that 75 of 84 teachers involve combat activities in P.E. classes. Of all of the questioned, 48 respondents were men and 34 women. Most of our respondents were between 31-40 years old. Most respondents teach only at E.P.A., 48 in total.

Pádecký, Jan ; Tufano, James Joseph (advisor) ; Pavelka, Radim (referee)
Title: Kinematic and dynamic characteristics of straight punches in elite male boxers Objectives: The purpose of this study was to quantify lower limb forces in the x, y, and z directions and their association with jab and cross relative peak force, and jab and cross peak velocity. Methods: A sample of 12 elite male subjects participated in the present study, which took place over two days. Subjects were familiarized with the procedures during the first day. During the second day, the subjects performed a standardized warm-up protocol, followed by one straight punch with the rear and then the lead hand to a force plate that was suspended in the air at the chin level by a cable system. The subjects were standing on two separate tri-axial force plates. Punch velocity was assessed using a Qualisys Motion Tracking Manager, where the marker used was placed in the middle of 12 OZ gloves. Results: Subject body weight resulted in a high positive significant correlation with jab and cross peak force, and a non-significant low and moderate positive correlation with jab and cross peak velocity, respectively. Partial correlation controlling for bodyweight resulted in a very high positive significant correlation between jab peak velocity and jab peak force and a high positive, but the non-significant...
