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.

Resting energy expenditure and nutritional intake in patients with pancreatic cancer before elective pancreatectomy
Heniková, Marina ; Gojda, Jan (advisor) ; Urbánek, Miroslav (referee)
Aims: The aim of this work was to determine whether a increased resting energy expenditure contributes to the nutritional risk for patients with pancreatic cancer. What the variability of resting energy expenditure is and whether it predicts weight loss. Another aim was to verify that lower protein-energy intake also has an impact on weight loss. Methods: Data for the diploma thesis were obtained from the project "Pancreatic Cancer: Metabolic Derangements Associated With Insulin Resistance", which takes place at the Department of Clinical Physiology of Metabolism at 2nd Department of internal medicine in the University Hospital Královské Vinohrady. The project includes 40 - 50 patients with pancreatic tumor resection per year. Data were collected from the beginning of December 2019 until the end of April 2020. The project is funded by the grant AZV NV19-01-00101. 10 consecutive patients (4 women and 6 men) with pancreatic cancer who had a complete dataset for analysis were selected for the research set for the diploma thesis. The patients underwent anthropometric examination, blood tests were taken, and indirect calorimetry was performed. Results: The first part of the research was focused on anthropometric parameters, parameters of nutritional status and the presence of cancer cachexia. The second...

Nutritional Status in Patients with Huntington's Disease and Nutritional Support
Kosheleva, Svetlana ; Klempíř, Jiří (advisor) ; Růžičková, Lucie (referee)
Huntington's disease is a dominantly-inherited autosomal neurodegenerative disease manifested by disorders of motility, cognitive function, behaviour, and weight loss, which is conditioned multifactorially. The aim of the study was to determine whether there are eating disorders in Huntington's disease, as well as its etiology and severity. Neurological scaling, anthropometric examinations, evaluation of three-day diet records, measurements with a manual dynamometer, bioimpedance analyses, indirect colorimetry and predictions of energy expenditure were performed on 10 patients. Algorithms were applied for the diagnosis of sarcopenia and malnutrition. Unwanted weight loss was observed in all patients and 4 out of 10 showed malnutrition. No difference was found between the values of measured resting metabolism and calculated according to the predictive equation. However, it has been shown that strict nutritional recommendations based on this data can be misleading for some patients with HN, as real energy consumption can be significantly higher. All our patients had a positive energy balance. A new diagnostic algorithm for the early diagnosis of sarcopenia has proven its worth. Using bioimpedance analysis and examination of the force of the handshake, we identified possible sarcopenia and already-present...

Podoba, Peter ; Baláš, Jiří (advisor) ; Heller, Jan (referee)
Title: Movement economy and physiological response during differing climbing speeds in sport climbers. Aims: The work aims to evaluace climbing economy and physiological responses of intermediate and advanced climbers in different climbing speeds. Methodology: 32 climbers (11 advanced men, 11 intermediate men, 10 intermediate women) performed 3 submaximal tests in treadwall at slope of 90ř at speeds 4, 6 and 9 m.min-1 . Each of the tests lasted exactly 4 minutes. Oxygen consumption (VO2), heart rate (HR), ventilation (VE), respiratory ratio (RER) and energy expenditure were monitored. Results: Advanced men reported lower energy expenditure than intermediate men in all climbing speeds (4 m.min-1 : -0,06 kcal.kg-1 , P = 0,007; 6 m.min-1 : -0,06 kcal.kg-1 P = 0,048; 9 m.min-1 : -0,07 kcal.kg-1 P = 0,022). Intermediate women reported only slightly lower energy expenditure than intermediate men (4 m.min-1 : -0,01 kcal.kg-1 P = 0,051; 6 m.min-1 : 0,06 kcal.kg-1 P = 0,091; 9 m.min-1 : -0,03 kcal.kg-1 P = 0,115). Energy expenditure was significantly lower at 4 m.min-1 than at 6 m.min-1 (-9,82 kcal, p = 0,001) and also signicantly lower at 6 m.min-1 than at 9 m.min-1 (-8,3 kcal, p = 0,001). Advanced men reported significantly lower VO2 at speeds 4 a 6 m.min-1 (- 2,2 ml.kg- 1 .min-1, P = 0,022; -3,9 ml.kg-1...

Sukovič, Richard ; Brtník, Tomáš (advisor) ; Šafránek, Jiří (referee)
VLIV VZTAHU DÉLKY DOLNÍ KONČETINY A VELIKOSTI RÁFKU NA PSYCHOFZIOLOGICKOU ODEZVU ORGANISMU Cíle: Cílem této práce je posoudit vliv délky dolní končetiny (DK) na psychofyziologickou odezvu organismu při jízdě na horském kole s odlišnými velikostmi ráfků. Metody: Soubor probandů tvořilo 20 mužů ve věku 26,4 ± 4,2 let. Jednalo se o experiment. Psychofyziologická odezva byla stanovena na základě výkonu (zajetého času), tepové frekvence a subjektivním hodnocení jízdních vlastností horského kola a vlastního vynaloženého úsilí hodnoceného na Borgově škále. Ke kontrolní analýze při testování byl použit přístroj MetaMax 3B. Testovány byly tři velikosti ráfků o stejné šíři plášťů. Jízdy byly realizovány na 800 m dlouhém okruhu. Testované osoby absolvovali každou jízdu s individuálně zvoleným fixním převodem v poloze v sedle s maximálním možným úsilím. Výsledky: Při jízdě na různě velkých ráfcích jsme u skupiny č. 2 (85 -90 cm DK) shledali velký rozdíl (P = 0,016) v dosažených časech při jízdě na různě velkých ráfcích. U skupiny č. 1 jsme shledali významné rozdíly v průměrné tepové frekvenci (P = 0,010), který činil 3 tepy a u subjektivního hodnocení vlastního vynaloženého úsilí pomocí Borgovy škály jsme se pohybovali na hranici významnosti (P = 0,060). Skupina č. 3 (97 - 101 cm DK) se pohybovala na hranici...
