Růžek, Ondřej ; Jindra, Matouš (advisor) ; Baláš, Jiří (referee)
Title: Effect of a bicycle's component on the energy expenditure Objectives: Aim of this bachelor's thesis is to determine the difference of energy expenditure in a different component mounting frame of the bicycle. Methods: The study involved 6 probands aged 25.5 ± 3.6 years. Energy expenditure was calculated on the basis of oxygen consumed (O2) and carbon dioxide exhaled (VCO2). To measure was used exhaled gas analyzer Metamax from Cortex and method spiroergometry. Probands completed two runs cadence of 95 rounds per minute on a bicycle with a different component (a shock). Completed line measured 750 meters, led to a gradient of 5 ř ± 2 řand lasts 3 minutes. Results: In our study we found that the differences in energy intensity during bicycling on a hard-tail bike compared to a full-suspension are due to the standard error of the analyzer exhaled gases Metamax® insignificant. VO2 values during the study period did not exceed the threshold of 2 ml /kg/min for the confirmation the authenticity of our hypothesis. Cycling with two shock-absorbers at a distance of 750 m long and 3 minutes remains segment with the inclination of 5 ř ± 2 ř cause energy expenditure in the average value of 161.23 ± 33.15 kJ versus bicycling without shock-absorber and 160.98 ± 24.10 kJ expenditure, which represents an...

Title: Comparison of energy expenditure when moving on wet and dry clothes. Objectives: The aim of this study is to compare energy expenditure based on heart rate when moving in dryand wet clothes in different speeds. Methods: Quantitative research and subsequent intra-individual comparison of pulse frequency and energy expenditure when moving in dry and wet clothes. Movements were conducted on a treadmill and heart rate was measured by using sporttesters. Results: From the results we can deduce that at the speed of 8 km/h is on the short track the move in the dry and wet clothing approximately at the same energy intensive. Furthermore, it was found that at higher speeds, the difference in heart rates is bigger and wearing a wet clothes at speeds 12 km/h approaches maximum heart rate.

Title: The energy cost of ski mountaineering. Aim: The aim of study was determine effect of speed and slope on energy expenditure during ski mountaineering. Methods: Twelve athletes (mean age 30 ± 8 years,) took part in the study. This was random intragroup experiment. The energy expenditure was determined by spiroergometry based on the ratio of O2 and CO2 exhaled. The anthropometric values and individual ventilation parameters was measured and followed individual warming up. The study was undertaken on the treadmill (Saturn HP Cosmos, Germany) allow to walking with specially adapted roller skis and poles modified for ski mountaineering. The test was initiated by a warm-up lasting for 4 minutes at speed at 3.5 km·h-1 and 16% slope. The next measurements consisted of 4 parts: walking at 24% gradient and speed 3.5 km·h-1 , 20% gradient and speed 4.2 km·h-1 , 16% gradient and speed 5.1 km·h-1 and 12% slope with a speed 6.8 km·h-1 . The load lasted for 8 minutes 30 seconds in order to achieve the elevation 200 m. The passive recovery for 20-25 minutes was administered between each measurement. Results: When the body was after the warm-up on load, the average energy expenditure nonlinearly increased with decreasing slope and increasing speed. The average energy expenditure at 24% slope and speed 3.5...
