Pilař, Lukáš ; Šteffl, Michal (advisor) ; Chrudimský, Jan (referee)
Title: The importance and use of compression garments in sports Objectives: The main aim of this thesis was to analyze the effect of compression garments on performance and recovery in sports. Methods: The work is realized as a review. There were searched three electronic databases: PubMed, Web of Science and Scopus for obtaining possible relevant papers. The same keywords were used to search in all the databases. Results: Based on the study of scientific literature, it was found that compression garments could provide a positive effect only under certain conditions. For speed-strength sports, the compression garments do not improve performance; however, they can reduce pain and fatigue after sports performance. In endurance sports, they can reduce heart rate and help ease the breakdown of lactate after exercise. Conclusion: Compression garments can improve conditions for sports performance, but their impact has not been fully demonstrated yet. Keywords: compression socks, recovery, regeneration, lactate, perceived pain

Čechová, Anna ; Suchý, Jiří (advisor) ; Gnad, Tomáš (referee)
Title: Comparison of training impact of striding versus double poling for cross country skiing. Objectives: The goal of the research is to find out and compare the difference between striding and double poling from the point of view of internal body impact, or lactate acid, heart rate and measured time of the performance in two consecutive days, respectively. Methods: This research is conceived as an empiric field research, which considers a comparison of lactate acid (LA) levels during cool down and heart rate (SF). Compared values were measured on roller skis in two consecutive days. Results: With the help of lactate acid levels, heart rate and measured times we found the main differences between striding and double poling. To the conclusion, we found out that striding was faster from measured time perspective and also the lactate acid levels were lower than for double poling. Keywords: Cross-country skiing, roller skating, heart rate, lactate, diagonal striding, double poling.

Hubička, Tomáš ; Jurák, Daniel (advisor) ; Čechovská, Irena (referee)
Title: Testing of Maximum HR in the Swimming Flum and Swimming Pool Objectives: The aim is to compare the detection method of max HR in a swimming Flum with the method of detection max HR in the classic swimming pool. By meeting other goals we want to determine which method is more precise, what the positives and negatives of individual measurements show and what the difference are practically max values observed in HR pool and the Flume compared with the results of theoretical calculation max HR. Methods: According to a pilot study with methodology of the thesis, HRmax was tested in a swimming Flum and the methodology according to Formanek and Horčic HRmax testing was carried out in the swimming pool. A sample of probands were selected from students UK FTVS. For the recording was used sporttester and data evaluation program execution Polar Precision Performance. To determine the submaximal swimming speed we used CSS test. This rate was also used to warm up before swimming test to the individual HRmax of probands in a swimming Flum. The measured data of both measurements were compared with each other and the results described and evaluated. Results: CSS gained speed in m/s, was used in the Flume in escalations test to HRmax. We measured values HRmax tests in a Flume and in a swimming pool. The Test...

Hyperbaric environment and its impact on the physical performance
Muráňová, Jana ; Vondrášek, David (advisor) ; Pavlů, Dagmar (referee)
Title: Hyperbaric environment and it's impact on physical performance Objectives: To investigate possible impact of of hyperbaric environment on individual's performance compared to normobaric environment with constant physical load. To outline the hyperbaric environment from physical side of view. To determine the usability of these effects for Training and regeneration purposes for athletes. Methods: The five respondents completed two sessions of Kinderman-Schnabell test. There was a seven days gap between hyperbaric and normobaric sessions to exclude the influence of fatique. Each session consisted of 40 seconds of sub-maximal load and a maximal load after 40 minutes rest. The squats were used as anaerobic type of load. The responders were taken a blood samples from finger and earlobe to state the level of lactate. Other measured indicators were blood pressure, heart and respirátory rate. The respondents also stated the subjective level of fatique using visual scale Results: The hyperbaric environment of 3 ATA had a significant effect on heart rate reduction. The sub-max load average was 86 bpm (resp. 99 bpm at normobaric environment) and the max-load average was 101 bpm (resp. 120 bpm normobaric). No significant effect was measured on blood pressure level averages. The sub-max load indicated...

The role of lactate shuttle in ischemic-reperfusion injury of rat heart adapted to chronic hypoxia
Kolář, David ; Žurmanová, Jitka (advisor) ; Nováková, Olga (referee)
Adaptation to hypoxia is a well-known phenomenon increasing myocardial resistance to ischemia-reperfusion (I/R) injury as an appropriate physical exercise which improves the contractile function of the heart. Lactate is a major energy substrate for the heart muscle during physical activity and hypoxia. The metabolism of lactate was and still is associated with muscle fatigue, but in the last decades it has been considered its significant modulating function of metabolism during exercise at cellular level and whole organism level. It has been shown that its effects might be similar to the effects of hypoxia and its oxidized form, pyruvate, has the cardioprotective effects. The aim of this study was to compare the expression of LDHA and LDHB isoforms between left and right ventricle in the cardioprotective scheme of adaptation to hypoxia. Another objective/goal was to determine the left ventricular response to I/R insult in the perfused heart model adapted to hypoxia compared with the normoxic controls on/at the expression level of both LDH isoforms. Our results showed differences in the LDHA expression in the left and right ventricle and an increased response of the left ventricle to I/R insult in rats adapted to hypoxia which is reflected at the expression level of both isoforms. Key words: heart,...
