The influence of feedback to improve freestyle techniques in children's categories 6 - 9 years old
Lachman, Ondřej ; Čechovská, Irena (advisor) ; Jurák, Daniel (referee)
Title: The influence of feedback to improve freestyle techniques in children's categories 6 - 9 years old Objectives: The aim of the thesis is to evaluate the effect of feedback to improve freestyle swimming techniques in children's categories 6 - 9 years. Methods: In this work, we used the methods of observation, expert assessment and analysis of video recordings in the training pool. To compare the effect of feedback on improving techniques be taught in groups monitored identical in content. Results: The results of our study show that the subsequent feedback through videos and verbal description has a positive influence on changing a crawl technique in children's categories 6 - 9 years. Key words: swimming, front crawl stroke, children swimming technique, analysis of videotapes

The aplication of CSS in swimming flume
Cagaň, Štěpán ; Jurák, Daniel (advisor) ; Chrzanowská, Babeta (referee)
Title: Application of CSS (Critical Swimming Speed) in the swimming flume. Objectives: Purpose of our pilot study was to find out, if load during swimming on speed of anaerobic threshold in the flume on level validated by accredited workplace corresponds with load during swimming in the swimming pool. Methods: For verification of our purpose, for each proband we first determined speed of anaerobic threshold, using Critical Swimming Speed protocol. Subsequently we monitored values of blood lactate and heart rate during swimming on anaerobic threshold speed level in the pool and thereafter in the flume. We have compared measured values. Results: We found out, that load in the flume is much lower, than load in the pool. We also found out, that stream of water in flume is not constant. Keywords: flume, swimming, swimming simulator, lactate, front crawl stroke, critical swimming speed

Measuring hearth rate of CP diagnosed individuals during swimming load
Šašek, Vít ; Prokešová, Eva (advisor) ; Hráský, Pavel (referee)
Title: Measuring max. hearth rate of CP individuals during swimming load Objectives: The major goal of this thesis is to measure heart rate of swimmers diagnosed with cerebral palsy during swimming load and to determine their CSS. Secondary goal of the thesis is to compare those values with intact population. Methods: In our thesis we tested HRMAX of 4 swimmers (3 men, 1 woman) with cerebral palsy (age 20 to 23 years) using the modified Critical Swimming Speed (CSS) protocol. A sample of probands was chosen out of swimmers participating in KONTAKT bB, swimming academy beyond borders programme. Testing went underway twice. CSS test consists of swimming two different distances with maximum effort. 25 and 100-meter distances (or modified shorter distances) were chosen for the purpose of measuring HRMAX. Sporttester was used for recording. We then compared obtained data with intact population by using substantive significance. Results: Tested values of the probands' HRMAX during CSS test were between 165 to 182 beats per minute. CSS reached 0,3 to 1,0 meters per second. In comparison with the sample of intact population, probands were able to reach the 8,9 % and 17 beats per minute lower level of HRMAX in average. Values of the CSS were averagely 78% lower than the CSS of the intact population sample....
