Punčochář, Michal ; Jindra, Matouš (advisor) ; Gnad, Tomáš (referee)
Title of the thesis: Interaction between a teacher and a student compared group and individual teaching skiing. Objectives: The aim of this work was to find, which and how big differences are in the didactic interaction in comparison of group and individual ski lessons. Methods: In this work we used the method of observation, data collection was realized using a video camera and the subsequent recording was evaluated using the MADI method (modified analysis of didactic interaction). Results: From the results we found that the greatest difference was in the expression factual purportwhich in individual lessons grow avarage by 20%. Furthermore, in the individual lesson form grow education activity above organizational by on avarage10% and in the type of attitude activity integration has increased on avrage 7%. The results also showed that in the individual form of teaching did not appear activity without direct control. Conclusion: The biggest difference between individual and group teaching was the increase in individual teaching in the expression of the subject matter, integration attitude activities above the dominant, the teaching activity increased over the organizational and the performance of the pupil's activity was constantly under direct control. Key words: Individual and group skiing...

Energy expenditure in ski mountaineering, depends on the carrying or pulling loads
Punčochář, Michal ; Jindra, Matouš (advisor) ; Brtník, Tomáš (referee)
Title of the thesis: Energy expenditure in ski mountaineering, depends on the carrying or pulling loads. Objectives: The aim of the study was to determine energy expenditure when compared skialpinism carrying or pulling loads. Methods: The study was attended by 9 men at an average age of 23.22 ± 3, who had previously had a skialpinist ski experience. It was an experiment. The amount of energy output was measured by indirect calorimetry, based on inhaled oxygen (O2) and exhaled carbon dioxide (CO2). The MetaMax 3B instrument was used to analyze inhaled and exhaled gases. Testing took place on a plane where everybody pulled 6-minute 15kg sleigh and then carried a 6-minute 15kg backpack at a speed of 4.5 km / h. Results: In 8 of the 9 tested, there was less energy expenditure when pulling the load on sleds than carrying it in the backpack. In 5 of the 9 tested, the difference between pulling and carrying was greater than the average difference of 4.57 kJ / min. For the three tested, the minimum differences between sleighs and backpack were minimal. One tested had a higher energy expenditure when pulling the load than when carrying it, but the difference was minimal. Key words: Energy demand, Ski-mountaineering, Carrying the burden
