Novotný, Otomar ; Jindra, Matouš (advisor) ; Matošková, Petra (referee)
Title: The Reliability of Measuring on the Skytech Interactive Ski Simulator Objectiv: The goal of this work is to investigate the reliability of the measurement of energy expenditure on the Skytech Interactive Ski Simulator. Methods: The sample consisted of 14 subjects, among which were 9 boys and 5 girls. The value of energy expenditure was measured by indirect calorimetry using the energy equivalent and respiratory exchange ratio. For the measurement of respiratory gases, the Metamax 3B metabolic analyzer and for the analysis of heart rate, the Polar S610 heart rate monitor were used. The subjects completed two measurements, each lasting 6 minutes. During this time, the data needed for subsequent calculations reliability were measured. Assuming that the pair of measuring has a two-dimensional distribution, the reliability equals the correlation coefficient. It was computed using the maximum likelihood method. Results: The measurement of energy expenditure on the Skytec Interactive Simulator provided consistent and reliable results. The findings in this study can be applied to further testing on this machine. Conclusion: The reliability of energy expenditure reached 84%, a result better than the usual values of reliability tests, which may typically be about 80%. Keywords: Energy expenditure,...

Chotěbor, Tomáš ; Brtník, Tomáš (advisor) ; Baláš, Jiří (referee)
Title: Energy expenditure of different size of mountain bike rims Objectives: The goal of this bachelor thesis is to gather and provide information on different energy expenditure (EE) of the organism when riding mountain bikes with different size of rims, while also considering different terrain. Methods: This thesis contains an experiment based on intra-individual measurements, which involved three participants of a similar age, weight, height and physical fitness. EE rate was determined based on the volume of oxygen consumption (VO2) and the amount of exhaled carbon dioxide (VCO2), i.e. by indirect calorimetry. For the measurement of respiratory gases device, we used Metamax 3B. The testing was performed with two wheel sizes, with diameters of 26 "and 29". The runs were carried out on natural circuit with different types of surface. Research participants completed two laps on both types of wheels. One ride lasted an average of 7:04 minutes. Results: We did not find a significant difference in energy expenditure (EE) when riding a mountain bike with the rims with a diameter of 26" and while riding on rims with a diameter of 29". The results of the experiment showed a slight difference in favour of the wheel diameter 29" however, regarding the standard error of measurement, this difference seems negligible...

Kopřiva, Jiří ; Fedák, Josef (advisor) ; Baláš, Jiří (referee)
Title: Appropriateness of choice to walk or run, depending on the speed of a quick relocation with load carriage Objectives: Comparison of physiological response of organism during the walk and run at speed 6 - 7,4 km.h-1 with carried load 15 kg with follow-up determination of critical speed in connection with economy of these activities where there were discovered sizes of correlation with proportional representation of fat free mass and working length of lower limb. Methods: The method applied in this research was the quantitative research based on intra-individual and inter-individual comparative analysis. Results: Based on the measured data it has been found out that there is a critical speed at 7,43 km.h-1 (±0,53), with respect to economy of walk compared to run with 15 kg load. The average heart rate during the critical speed was 129 BPM (±9,67). The average energy expenditure per minute during the critical speed was 11,9 kcal (±2,04). In addition there were discovered sizes of correlation between critical speed and the working length of lower limb where rP = 0,9203 was statiscitally significant. (α = 0,05) and between critical speed and proportional representation of fat free mass, where rP = 0,1529 was not found to be statistically significant (α = 0,05). Keywords: quick relocation, load...

Determination of exercise post-oxygen consumption (EPOC) following resistance training, and aerobic exercise
Galertová, Alena ; Petr, Miroslav (advisor) ; Sedlak, Petr (referee)
Oxygen debt repayment after completion of intense muscular activity reflects the significant involvement of anaerobic metabolism druring exercise. Some studies have reported an increased oxygen consumption even after 24 to 48 hours after strength training character, while after the activities of lower intensity (the aerobic exercise) is the oxygen consumption increased only in the order of several hours. In common practice, especially in the selection of the most suitable forms of exercise to increase energy expenditure in the general population, this is not usually a calculated factor. The aim of the thesis is the comparison of the energy expenditure by using indirect calorimetry and monitoring of selected individuals and at intervals after completion intense muscular activity and after aerobic exercise.
