Musil, Albert ; Baláš, Jiří (advisor) ; Gajdošík, Jan (referee)
Title: Critical force of finger flexors in sport climbers Targets: The aim of this study is to assess the validity of a graded test for determining critical strength of finger flexors and climbing performance in sport climbers. Methods: The research sample consisted of 26 participants, including 8 women and 18 men (age 28.3 ± 7.6 years, body weight 70.8 ± 10.5 kg, height 174.6 ± 6.9 cm, climbing experience 10.4 ± 5.1 years). Two tests were conducted over two visits: a 4-minute all-out test and a graded test. Tissue saturation index (TSI), oxy[heme], and deoxy[heme] were recorded using NIRS Portamon on the flexor digitorum profundus. The diagnosis of the critical force (CF) threshold of the graded test was based on TSI, oxy[heme], and deoxy[heme] values. Results: The CF from the graded test was on average lower (8.4 ± 3.2 kg) compared to the measured CF from the all-out test (20.6 ± 6.1 kg). The correlation of CF as a percentage of body weight (%TH) from both tests with RP performance reached the same values (r = 0.79). The highest relationship with RP performance in the graded test was found in the peak maximum force (%TH) r = 0.80. The lowest relationship with RP performance in the graded test was found in CF (%TH) r = 0.40. Verification trials with one participant indicated that CF might be at...

Title of thesis: Benefits and risks of Parkrun The thesis dealt with the Parkrun project, which can be classified as outdoor activity. The aim of the thesis was to assess the health and social benefits and risks of Parkrun. This is a research paper, the main sources of information of which were the electronic database EBSCO and the official website of the Parkrun organization, together with electronic articles and reports about Parkrun. When assessing the health benefits and risks of Parkrun, the thesis reached the following conclusions: Parkrun brings physical health benefits in the form of general improvement and maintenance of physical fitness. In particular, it helps to reduce the level of cholesterol in the blood, reduce the risk of obesity, diabetes, and thus represents the prevention of the occurrence of civilization diseases. In addition, it can dampen the symptoms of asthma and help reduce the inflammation of the airways. Risks for physical health can be extreme manifestations of the weather - especially heat or cold. Another risk may be the load on the joints in the case of incorrect technique and the predominant hard surface. Parkrun also brings benefits in the field of psychological health in the sense of a general feeling of satisfaction, happiness, joy, self-confidence, as well as a...

Title: Relative Age Effect in Czech Sport Climbing Objective: The aim of this thesis is to investigate the manifestation of the Relative Age Effect in selected talented youth and the adult national team of sport climbing in the Czech Republic. Methods: The study analyzes the statistical significance of the expected and actual distribution of birth months in the sample studied. The research sample includes 173 subjects who have been selected for Youth Sports Centers, Elite Sports Centers for Youth, or National Sports Centers for Youth and the national sport climbing team. The chi-squared test, in the form of a goodness-of-fit test, is used to assess the manifestation of the Relative Age Effect. Results: In the overall sample studied (173 subjects), no statistically significant difference was found in the frequency of births between the first and second halves of the year. The Relative Age Effect was not demonstrated in men, while in women, a statistically significant difference was found, with a higher number of births in the first half of the year. This indicates the presence of RAE in women in Czech sport climbing. Further results relate to specific groups within the sample, such as members of youth sports centers and national teams. Conclusion: The manifestation of the Relative Age Effect was...

Ťuka, Jeroným ; Baláš, Jiří (advisor) ; Krupková, Dominika (referee)
Title: Effect of caffeine on local isometric performance of fingers in sport climbers. Targets: The aim of this study was to investigate whether caffeine affects local isometric finger flexor performance in sport climbers during a 4 minute all-out test and the maximal force test. Methods: 12 climbers participated in the testing during 3 visits to the LSM laboratory at the UK FTVS. During each visit, they completed a maximal strength test, a force gradient and an all-out test on a specific dynamometer. During the second and third testing we randomly administered caffeine or a placebo to the climbers and monitored whether there was a change in performance. Results: The average maximal force during the initial measurement was 48.8 kg (σ = 12.5 kg), with caffeine supplementation the average maximal force increased to 48.9 kg (σ = 11.5 kg). The average total work during the initial measurement was 3573.3 kg.s (σ = 810.2 kg.s), with caffeine supplementation there was an increase to 3700.8 kg.s (σ = 865.7 kg.s). The average work performed above critical strength during the initial measurement was 1242 kg.s (σ = 726 kg.s), with caffeine supplementation there was a decrease to 1215.2 kg.s (σ = 456.1 kg.s). The average critical force during the initial measurement was 15 kg (σ = 5.9 kg), increasing to 15.9...
Physiological response to adventure activity
Řezník, Ondřej ; Psohlavec, Lukáš (advisor) ; Baláš, Jiří (referee)
Objectives: The aim of this study was to investigate the effect of height on the physiological response of the body and walking speed during challenge activity. Methods: The study included 27 subjects, with an average age of 23±2, who were students of the Faculty of Physical Education and Sport (FTVS) at Charles University. The participants walked for 4 minutes over a low obstacle and 4 minutes over a high obstacle at their own pace, followed by 4 minutes over a low obstacle at a specified speed. The monitored parameters were heart rate (HR) and speed (V). Results: The average HR during walking over a low obstacle at the specified speed was 100 beats per minute (σ=12.335), and the average speed was 0.272 (σ=0.221). During walking over a high obstacle, the HR was 133 beats per minute (σ=16.125). During walking over a low obstacle at their own pace, the average HR was 111 beats per minute (σ=13.416), and the average speed was 0.706 (σ=0.269). Conclusion: Walking at height reflects the subjectively perceived risk through physiological responses. The height of the obstacle, which induces a subjectively perceived risk, increases the heart rate by 33 %. The walking speed decreased by an average of 0.434 m/s on the high obstacle. Kewords: adventure education, risk, heart rate, stress.
