Energy expenditure in Zumba
Řehořková, Michaela ; Baláš, Jiří (advisor) ; Bunc, Václav (referee)
The main objective of this study was to assess the energy demand of Zumba. The energy demand was determined by the indirect calorimetry. Four middle-ages women experienced in zumba participated in the study. A walking test untill the individual maximal exhaustion was performed on a treadmill to determine the relationship between heart rate, pulmonary ventilation and oxygen consumption. The energy expenditure of zumba was undertaken during 3 lessons, which took place at intervals of 3-5 days. We found an average oxygen consumption of 25,73 ± 0,95 ml.min-1 .kg-1 , which corresponded to the energy expenditure of 0,55 ± 0,03 kJ.min-1 .kg-1 . Therefore, we consider Zumba as the activity with high energy demand.

Utilisation of nutritive substrates at polytraumatic patients.
Valentová, Gabriela ; Hronek, Miloslav (advisor) ; Havel, Eduard (referee)
There are significant differences in the metabolism of nutritional substrates in polytrauma patients. The actual metabolic needs of the patient may not be achieved despite the guidelines and recommendations for energy supply in the parenteral and enteral form of nutrition are followed. Subsequently this may lead to the occurrence of complications. The aim of the study was to compare the energy intake of each nutrient substrate supplied with nutrition by finding the nutritional substrate utilisation value which is obtained from indirect calorimetry measurements in patients with multiple injuries at the surgical ICU 1 of the Hradec Králové Teaching Hospital. By comparing this data you can obtain the optimum value for the nutritional needs of the patients. In the study we used seven spontaneously breathing polytrauma patients, three women and four men, of an average age of 41±21 years. Utilisations of nutritive substrates of each patient were obtained by indirect calorimetry. Accurate information on the amount and composition of nutrition supplied over 24 hours was also obtained. The patients received an average of 3.80±1.40 g/kg/day of carbohydrates, 1.03±0.56 g/kg/day of lipids and 1.40 ± 0.44 g/kg /day of proteins. The total energy intake was on average 30.94±11.03 kcal/kg/day. In six of seven...

Doleželová, Magdaléna ; Kovařík, Miroslav (advisor) ; Hronek, Miloslav (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Student: Magdaléna Doleželová Supervisor of master thesis: PharmDr. Miroslav Kovařík, Ph.D. Title of master thesis: Body composition parameters in dependence on the metabolism degrese in patiens with COPD Chronic Obstructive Pulmonary Disease (COPD) is a very serious illness characterized by incompletely reversible airflow obstruction and lung emphysema. Contributes to its overall severity are extrapulmonary manifestations, especially cachexia and loss of lean tissue mass. Chronic inflammation of the respiratory airways and increased respiratory effort cause the hypermetabolic state to some patients with COPD. This thesis investigates the impact of increased metabolism on body composition in patients with COPD. Our study included 50 COPD patients (38 men, 12 women) who were examined by bioelectrical impedance. In this study, we compared the parameters of body composition of men with resting energy expenditure REE > 130% (hereinafter Men over 130%) (n = 9) and the group of men with REE < 130 % (hereinafter Men below 130 %) (n = 29). In the group of Men over 130 % we found a lower average value of body weight by 18 % compared to Men below 130 %. Total body and intracellular water were 12 %...

Řehořková, Michaela ; Strejcová, Barbora (advisor) ; Bunc, Václav (referee)
Title: The energetic cost of middle aged women during zumba lesson measured by indirect calorimetric method Objectives: The aim of this study is to assess energy cost of the middle aged women during zumba exercise. Methods: A group of 6 women (age range 27-37 years) volunteered to participate in this study. To assess the maximal oxygen consumption, we used the running test to individual maximum. Each subject took part in six lessons of zumba in commercial fitness gym. Each subject was measured during 60 min long lesson. Results: The oxygen consumption of the whole zumba exercise was 19,5±2,2 ml.kg-1 .min-1 that is 68,4 % of the maximal oxygen consumption 40,1±7,4 ml.kg-1 .min-1 measured during running test. That exactly means a caloric expenditure 404,8 kcal (or 1692,2 kJ) during one lesson of zumba. The intensity of whole class reported by HR was covered by 67,5 % from HRmax and by Borg's rates of perceived exertion (6-20) with rates 14±2 from 18±2 immediately after the maximal running test. The highest energetic cost (336, 3 kcal, resp. 1405,9 kJ) was during the main part of the lesson. Zumba can be classified as moderately challenging type of exercise, which is good for fat burning; this statement is based on values of the heart rate measured during lessons of zumba. Key words: zumba, energetic...

Effect fo different sizes of wheels of in-line skates on energy expenditure
Sukovič, Richard ; Jindra, Matouš (advisor) ; Brtník, Tomáš (referee)
EFFECT OF DIFFERENT SIZES OF WHEELS OF IN-LINE SKATES ON ENERGY EXPENDITURE Objectives: The aim of this bachelor thesis is to determine the difference in energy expenditure when using different sizes of wheels of in-line skates. Methods: The research group consisted of 5 people in age 26,4 ± 2,2 years. This was an experiment. The calculation of energy expediture was based on the amount of oxygen consumption (VO2) and exhaled carbon dioxide (VCO2), i.e. indirect calorimetry. For the analysis of respiratory gases MetaMax 3B measuring device was used. Three sizes of wheels of the same hardness were tested. The rides were carried out on a 1,5 km section of a cycle path with the effect of the height difference of 2 mm/m. Probands completed one test ride (with a cadence of 70 rpm) on each size set of wheels. Test ride lasted for 5 minutes. For results were processed values of 3 minutes steady state VO2. Results: We found out a noticeable difference in energy output between 72 mm and 90 mm large wheels. The difference between driving on 72 mm and 80 mm large wheels and driving on 80 mm and 90 mm large wheels was, due to the standard error of measurement, insignificatnt. Conclusion: The energy expenditure reached a noticeable increase in driving with a larger diameter of wheels compared to driving on...

Energy cost of slacklining
Klaus, Jan ; Baláš, Jiří (advisor) ; Hráský, Pavel (referee)
Title Energy expenditure of slackline walking Objectives The aim of this study was to investigate the energy expenditure of slacklining in intermediate and advanced slackliners. Methods In this observatory study, 19 slackliners (10 intermediate, of which 7 men and 3 women, 9 advanced, of which 7 men and 2 women) completed experimental energy expenditure measurement of slacklining using indirect colorimetry. The MetaMax 3B metabolic analyzer (Cortex Biophysik, Germany) was used to determine respiratory parameters and the heart rate monitor (Polar Electro OY, Finland) was used to determine the heart rate (HR). Comparative statistical tools were used in the data analysis. Results Relative energy expenditure of 0,471 kJ·min-1 ·kg-1 was found in intermediate slackliners and 0,377 kJ·min-1 ·kg-1 in advanced slackliners in walking on a 10 m long slackline at a constant speed of 15 m·min-1 . In the static standing on slackline, the relative energy expenditure was found to be 0.368 kJ·min-1 ·kg-1 in intermediate slackliners and 0.289 kJ·min-1 ·kg-1 in advanced slackliners. The weighted arithmetic mean for HR in men and women walking on the slackline at 15 m·min-1 was at 67.3% of the predicted HRmax (220 - age for men, 226 - age for women). The MET value in the advanced group (n = 10) was set at 5.15, and in...

Hlaváček, Lubomír ; Baláš, Jiří (advisor) ; Gajdošík, Jan (referee)
Title: Metabolic response of indoor rock climbing and treadwall climbing Objectives: The goal of this work is to compare the differences between an indoor rock climbing and treadwall climbing in terms of the metabolic response of the organism. Methods: Forty-two climbers of three different performance levels participated in the research, who during seven days underwent in random order, separate measurements on an indoor wall and a climbing simulator at a speed of 4 m.min- 1 to a height of 19.5 meters with a slope of 90˚. The values of the metabolic response of the organism were monitored, specifically oxygen consumption (VO2), minute ventilation (VE), respiratory rate (DF), respiratory exchange ratio (RER), heart rate (HF), energy consumption (ES) and rating of perceived exertion (RPE). Results: Climbers of lower performance level were reaching average values of VO2, VE, DF, RER and ES higher than advanced climbers, both on the indoor wall and the an treadwall. In terms of average EC values, the indoor wall is more demanding for all groups (lower performance: treadwall 0.59 ± 0.07 kcal·kg-1 , indoor wall 0.69 ± 0.08 kcal·kg-1 ; intermediate: treadwall 0.57 ± 0.09 kcal·kg-1 , indoor wall 0.64 ± 0.11 kcal·kg-1 , advanced: treadwall 0.56 ± 0.08 kcal·kg-1 , indoor wall 0.62 ± 0.06 kcal·kg-1 )....

Effect of body composition on resting metabolic rate in obese patients
Staňová, Alžběta ; Sadílková, Aneta (advisor) ; Mikeš, Ondřej (referee)
Introduction: Changes in eating habits and incorporation of physical activities remain to be the main methods in treating obesity. To set an adequate calorie intake, which would lead to weight loss, it is necessary to determine energy needs of an individual. For that energy intake and energy expenditure need to be determinate. However, energy expenditure is difficult to determine since it is contributed of three components. Basal, respectively resting metabolic rate (RMR), which is affected by a body composition, has the greatest influence on a total energy expenditure. Indirect calorimetry (IC) is considered to be a gold standard to determine RMR. When RMR is calculated by prediction equations instead, such as Harris-Benedict (H-B) equation, energy needs are overestimate or underestimate for people with abnormal body composition. Objectives: The aim of this study is to analyse data of RMR obtained using IC in connection to body composition. The main aim is to determine how fat free mas (FFM) and fat mass (FM) are affecting RMR in obese patients. There is also a comparation of RMR measured by the IC and RMR calculated using H-B equation as a part of this study, while IC is considered to be a reference method. Methods: Patients new to ambulance of obesitology at General University Hospital in Prague...

Validity of predictive equations for determining resting energy expenditure
Fabián, Patrik ; Korvas, Pavel (referee) ; Chlíbková, Daniela (advisor)
This bachelor thesis deals with the validation of predictive equations to determine resting metabolic rate. The objective of this bachelor thesis was to compare individual predictive equations for determining resting metabolic rate with self-measurement using indirect caloriemetry and to establish a own procedure for predicting resting metabolic rate. The evaluation of each predictive equation was based on statistical analyses. Based on statistical analyses, it was found that the available predictive equations underestimate resting metabolism by an average of 20 % of kilocalories per day compared to the value measured by indirect calorimetry. Machine learning was used to determine the actual procedure for predicting resting metabolic rate, which was then presented using the user interface. The following testing showed that the neural network for predicting resting metabolic rate provides more accurate results compared to the available predictive equations.
