Title: Comparison of universal and specific functional stress tests of ski-mountaineerers. Objectives: The aim of the thesis is to compare maximal functional parameters of ski-mountaineerers measured during three functional laboratory stress tests. The functional stress tests were set on a treadmill, bicycle ergometer, and on a ski-mountaineer trainer. Consecutively, there is evaluated the meaning of testing of the functional parameters on the ski-mountaineer trainer. Methods: Interindividual and intraindividual descriptive study of 10 ski-mountaineerers of middle and high level performance. Results: The respondents reached the average value of VO2max 63,3 ml.kg-1 .min-1 on the ski-mountaineer trainer, 67,5 ml.kg-1 .min-1 on a treadmill and 66,5 ml.kg-1 .min-1 on a bicycle ergometer. The average measured HR on the ski-mountaineer trainer was 179 heartbeats/min, on the treadmill 185 heartbeats/min and on the bycicle ergometer 183 heartbeats/min. The average value of R reached the value of 1,09 on the ski-mountaineer trainer, 1,18 on the treadmill and 1, 19 on the bycicle ergometer. The highest measured value of VO2max reached on the treadmill was 79,3 ml.kg-1 .min-1 , the bycicle ergometer enabled to reach maximum 76,5 ml.kg-1 .min-1 and the highest value reached on the ski-mountaineer trainer was...

Analysis of Avalanche Danger Awareness in the Krkonoše Mountains by ski mountaineers
Fricová, Pavlína ; Brtník, Tomáš (advisor) ; Jindra, Matouš (referee)
Title: Analysis of Avalanche danger awareness at Giant Mountains by backcountry skiers. Objectives: Goal of bachelor thesis is analysis of awareness and foreknowledge about danger of avalanches occurrence, avalanche rescue and above all avalanche prevention at both advanced and beginning backcoutnry skiers who sets to Giant Mountains to do skitouring tours. Methods: The practical part of the thesis has a character of quantitative research. A questionnaire was carried out on a sample of backcountry skiers of all levels. Based on the analysis of the obtained data from the quantitative research, the awareness of the avalanche danger among the backcountry skiers in the Giant Mountains was evaluated. Results: Based on the obtained data was found that 40 % of the total number of backcountry skiers in the Giant Mountains visited them for the purpose of skitouring for the first time this year. Most of the respondents stated that they were aware of the risk of avalanche danger. Nevertheless, 77.5 % of the interviewed were moving on the open terrain during the skitouring tour, of which 25 % were beginners who did not have sufficient experience with it. Only 25 % had avalanche safety equipment, but only 60 % of them performed mutual control of avalanche rescue beacons Conclusion: Based on the results of the...

3 Abstract Title of the thesis: Monitoring the performance of Czech three years before and three years after the introduction of the Central European Cup in ski mountaineering Objectives: The aim of this bachelor thesis is to compare the performance of the Czech Republic representation in ski mountaineering at the World Cup three years before and three years after the introduction of the Central European Cup (SEP) in 2016 and find out if SEP really contributed to the increase in the success of Czech competitors at the World Cup. Methods: This work is conceived as an empirical-theoretical research work. The research group consists of representatives of the Czech Re- public in ski mountaineering who participated in the World Cup from the racing season 2012-13 until 2017-18. I compared their total points earnings on the World Cup before and after the introduction of SEP and as a comparative test I used Mann-Whitney U test. Results: According to the total number of points earned in the whole season, it is assumed that the competitors were more successful before SEP was established. According to the comparative Mann-Whitney U test, the difference between pre and post SEP data is not significant. Therefore, the thesis did not confirm that SEP has contributed to increasing the success of Czech competitors at...

Analysis of competitive ski mountaineering and use of a hypoxic environment
Legová, Tereza ; Jindra, Matouš (advisor) ; Gnad, Tomáš (referee)
Based on a search of available resources, I report on racing skialpinism and training at higher altitudes. The aim of this work is to compare the performance of the reprezentation of Czech Republic, Slovakia and Poland in skialpinism at the World Cup, World and Europe Championships three years before and three years after the Central European Cup (SEP) (2016). And to find out if SEP really contributed to increasing success at these international races. I have analyzed the numbers of competitors and the success of the countries participating in SEP in the World Cup, the European and World Championships before and after the introduction of SEP. I also compared the altitude profile of the World Cup races in skialpinism and compared it to the Central European Cup (SEP). I focused on the average altitude of the race, track length, elevation and the highest peak. According to the findings, Czech competitors were more successful in skiing before the SEP, either in the World Cup or in the European and World Championships. SEP races compare to the World Cup are laid down below, shorter and lacking a technical passage. On the other hand, the competitors get more meters over them. Based on these results, I suggest that races in skialpinism within SEP should be more similar to the World Cup, at least in terms...
