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...

Comparison of energy expenditure when moving on wet and dry clothes
Hrubý, Pavel ; Sýkora, Karel (advisor) ; Jindra, Matouš (referee)
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. Keywords: Energy expenditure, heart rate, military swimming, moving in difficult condition

Physical activity for health in sport youthα
Kokštejn, Jan ; Kokštejn, Jakub (advisor) ; Frýbort, Pavel (referee)
Title of Bachelor thesis: Physical activity for health in sport youth Author: Bc. Jan Kokštejn Head of work: Mgr. Jakub Kokštejn, Ph.D. Aim: Findings the size of physical activity in youth soccer players during a week mode and comparison of selected indicators with recommendations of physical aktivity for health promotion. To identify possible differences in physical activity between younger (16-17 years old) and older (18-19 years old) players in adolescent category. Methods: The research samples consist of younger soccer players (n=25; 16,2±0,9 years old) and older soccer players (n=25; 18,6±0,3 years old). Accelerometers Actigraph GT3X were used for determining level of physical activity during the week. Results: The average daily amount of modern to high intensity physical activity exceeded in both groups of soccer players worldwide used recommendations, which is 60 minutes. For daily number of steps, the group of younger players exceeded recommended amount according to Sigmund et al. (2005). The group of older players remained just below this threshold, but within the recommended range. In terms of energy output both groups reached values between 8-9 kcal.kg-1 .day-1 , according to selected criteria met physical activity recommendations. Energy output value and the number of steps did not...

Comparison of energy expenditure in single rope techniques using a different ways of ties
Rozsypal, Karel ; Majerčík, Petr (advisor) ; Sýkora, Karel (referee)
Thesis title Comparison of energy output of one rope techniques using different types of ties. Aims The aim of this thesis is the comparison of energy output of rope climbing with load using full body harness and sit harness. Methods used In this thesis an energy output measurement is being carried out using CORTEX METALYZER® apparatus during rope climbing. In the first measurement probands were tested during rope climbing with load using sit harness only. In the second measurement probands were tested during rope climbing with load using full body harness (i.e combination of both sit and chest harnesses). To compare the results obtained, qualitative analysis a a T-test were used. The results Based on the data obtained and the T-test later performed, no significant difference was found between the measurement readings of sit harness climbing and full body harness climbing. According to the qualitative analysis performed, correlation was found out between preffered sport activities a the measurement results, wherein the persons doing aerobic activities showed lower readings of energy output during rope climbing in the second measurement during rope climbing with load using full body harness, whereas the persons doing aerobic-anaerobic activities showed lower readings of energy output during rope...

Funfálek, Tomáš ; Sýkora, Karel (advisor) ; Jindra, Matouš (referee)
Title: Comparison of the level of effort during the skitouring and snowshoeing movements in an adjusted terrain. Goals: Based on the results of heart rate- find out and compare the level of effort and energy output during the ski touring and snowshoeing movements at three different speeds and in an adjusted terrain. Method: Quantitative measuring of the heart rate and energy output using a heart rate monitor and intrapersonal comparative analysis of measured values during the ski touring and snowshoeing movements. Key words: Heart rate, energy output, snowshoes, ski touring, Army of the Czech Republic, movements on the snow and ice.

Hepnar, Jan ; Vomáčko, Ladislav (advisor) ; Jindra, Matouš (referee)
Title The energy performance at the growth rate in ski-mountaineering Objectives Measure group skialpinists of different ages and performance of the ski-mountaineering simulator with a gradient 21ř and speed 1,4 km/h to 5,4 km/h with increasing 0,4 km/h in every minute. Determine their energy expenditure in different speeds as the speed increases and with constant slope. Methods Seven ski-mountaineerers of different levels were testing in laboratory of ski-mountaineering simulator. We calculate of maximum oxygen consumption and anaerobic threshold. Results The probands attained average energy expenditure 8,18 kJ per minute at the end of the first minutes and they attained average energy expenditure 29,32 kJ per minute at the end of the 10th minutes. The average energy expenditure of probands increased by 2,35 kJ per minute an average with a standard deviation 0,69 kJ per minute.

Evaluating the amount of physical activity of football players at grade level.
Kosina, Jan ; Kokštejn, Jakub (advisor) ; Frýbort, Pavel (referee)
Bachelor thesis "Evaluating the amount of physical activity of football players at grade level" deals with finding new knowledge concerning the size and composition of the physical activity of adolescent football players. In the theoretical part are being collected knowledge about physical activity and health recommendations concerning the composionfor the age group of adolescents. Amount of physical activity was measured by heart rate sensor, accelerometers and a written record. The evaluation, which is given in the final part of the thesis shows that adolescent football players at grade level are below health recomendations for daily energy expenditure in the prevailing numberof days of the week. In cotrast, in the days when ongoing trining units, they exceed recommendations several times. Regarding the average lenght of sleep, it was found, that the majority of players younger from both categories exceeds recommendations for their age while the results of most players of the older dategory correspond health recommendations.
