Title: Terrain and laboratory testing in Snowboardcross Objectives: The main aim of this bachelor thesis is to compare the validity between terrain and laboratory tests and to evaluate the relationship of tests and the rating of the Czech National Cup in snowboardcross. Methods: Laboratory measurement of lower body measured by Bosco test (repeated jumps per 60 seconds), followed by terrain testing of lower body, which is consisted of broad jump, triple jump and shuttle run 4x10 meters. The probands are 3 female athletes in snowboardcross discipline, aged from 13 to 15 year old. The results of terrain and laboratory testing was compared with the results of rating of Czech National Cup. Results: We discovered that laboratory and terrain tests are similar. The probands has had the same position in 5 tests of 6 total. That means, that proband with the best results of terrain testing has also the best results in laboratory testing. But no proven connection between results of the test and their standing in rating of the Czech National Cup was found. The results of the best proband proved the best performance in races, but the results of remaining probands didn't confirm this relationship. The proband with the worst results of testing (laboratory and terrain) took 4th place in the rating of the Czech...

Title: A comparison of dynamic abilities in nordic ski disciplines Aim: This dissertation aims to compare the dynamic abilities of cross country skiers and ski jumper in age between 12 to 15. Clarification of whether or not a training process of those two athlete groups has a crucial impact on the development of mentioned abilities compared to the other hobby sports group (target group). Methodology: This dissertation is conceived as empiric-theoretical. It analyses the results of samples to verify the hypothesis. There were three groups consisting of 10 samples (athletes) in total. The samples were tested in horizontal jumps (long jump, triple jump, multiple jumps) and vertical jumps (squat jump, counter movement jump). In all tests, it was decided to use only the best of all three attempts for the results. Findings: Development of dynamic abilities during the training process has a positive impact on their development in general. Both cross country skiers and ski jumpers achieved better results than the target group. Furthermore, ski jumpers performed better than cross country skiers.
