The energy expenditure at critically ill patients
Švrčková, Alexandra ; Hronek, Miloslav (advisor) ; Havel, Eduard (referee)
The aim of this study was to determine energy expenditure and to find relations between resting energy expenditure (REE) and selected parameters in 14 polytraumatic patients in the ICU of University Hospital in Hradec Kralove, which were easily measurable and usable for REE prediction. In this study 7 men (age 36 ± 18 years) and 7 women (age 58 ± 28 years) with polytrauma were examined. The assessment of REE was measured via indirect calorimetry (IC) method. The examination also included bioimpedance analysis (BIA). BIA was useful especially for obtaining values of overhydration (OH), lean tissue mass (LTM) and metabolically active body cell mass (BCM). Average REE-IC (measured by IC) was 2116 ± 516 kcal·day-1 in men and 1450 ± 407 kcal·day-1 in women (P = 0.018). Statistically significant difference between men's and women's population was also found in these relations: calculation of basal energy expenditure according to Harris-Bennedict equation without (P = 0.001) and with deduction of OH from body weight (P = 0.001), at "breathing energy expenditure" (REE related to respiratory rate) (P = 0.018) and at (REE related to heart rate) "heart rate energy expenditure" (P = 0.038). REE-IC related to kilogram of BCM with and without deduction of overhydration was shown as statistically significant...

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...
