Rafael, Gáll ; Petr, Miroslav (advisor) ; Šteffl, Michal (referee)
Title: Hormonal changes in strength training Objectives: Perform a systematic review of literature dealing with hormonal changes in strength training. Based on the informations from aforementioned literature, describe wheather acute hormonal response after a bout of strength training significantly influence the proces of hypertrophy or not. Hormone testosterone and changes of its concentrations is for this thesis the most important. Methods: Method of traditional review was used in this thesis. Results: The presence of acute hormonal changes occurred in strength training was confirmed in numerous studies. Role of this hormonal response is because of variability in results not very clear yet. Chronicle changes of resting hormonal levels in strength training are not observed according to results of studies. For better understanding of hormonal strength in strength training, another studies have to be executed. Keywords: endocrinal system, strength training, hormonal response, testosterone, hypertrophy.

Vopravil, Ladislav ; Bunc, Václav (advisor) ; Petr, Miroslav (referee)
Title: Specifics of Pre-Competition Training in Bodybuilding and it's Influence on Body Composition Objectives: The aim of this thesis is description of specifics nutrition and training methods in pre-competition training in bodybuilding and practical assessment of their influence on body composition in the test subjects. Methods: Skinfold calliper technique using callipers type Best and bioimpedance analysis using devices BIA 2000 and Tanita MC-980. Results: After completing of intervention program and measurement of body composition, compiled on the basis of negative energy balance, using carbohydrate restriction combined with high-intensity strength training and subsequent measurement of body composition, we found an expected changes of their parameters as was observed their individual response on intervention. Both subjects achieved a significant reduction of subcutanneous fat (proband no. 1 = - 7 %, proband no. 2 = - 3,2 %) and total fat (proband no. 1 = - 2,7 ± 0,3 %, proband no. 2 = - 3,2 ± 0,4 %). Furthermore we observed a distinct change in the total amount of muscle mass (proband no. 1 = - 2,5 kg, proband no. 2 = + 1,1 kg) while deterioration of muscle quality defined by changes of ECM / BCM coefficient values. Conclusion: The program has ensured the expected changes in the parameters of...

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.

The influence of a high-fat diet on the parameters of body composition
Jelínek, Ondřej ; Coufalová, Klára (advisor) ; Petr, Miroslav (referee)
Title: The influence of a high-fat diet on the parameters of body composition Objective: Evaluation of the effects of a high-fat diet on weight, body composition and intervening variables in both diabetic and non-diabetic patients, comparing these effects with those of diets of lesser fat content, and an evaluation of these findings with latest dietary guidelines of WHO, FAO and Ministry of Health of the Czech Republic. Methods: The design of this thesis is a review of randomized controlled trials and randomized crossover trials. A total of 17 trials were included, regardless of their blinding and their energy or saturated fat restriction. No specification of inclusion criteria with regard to minimal sample size or minimal duration of the intervention was made. Results: The trials have shown that a high-fat diet produced on average greater weight loss in the short-term than a diet with lesser fat content, however, by 1 year the differences were not significant. No differences were observed between the effects of the diets on fat mass or fat free mass in any of the trials included. Trials comparing the effects of diets on appetite have shown that fat has a greater satiating effect than carbohydrate, but lesser satiating effect than protein. The findings didn't fully correspond with official...

Anthropometry and 3D scan differences of upper body in resistance trained athletes and soccer players
Čečelský, Jakub ; Šťastný, Petr (advisor) ; Petr, Miroslav (referee)
The name of this dissertation: Differences between comparison using anthropometry and 3D scanning of the upper body with a power-trained athletes and football players. The aim of this dissertation: Compare the outputs of anthropometric measurements and measurements using 3D scanning for upper body power-trained athletes and football players. Method: The contents of this work was measured antropometri (height, weight, length arm width skinfold, measurement epicondyle, physical circuits) scanning both arms chest. Somatotype was measured using a method of Heath-Carter. Correlation analysis was used to search the potential of the relationship between variables. The sample consisted of 24 subjects in two groups. ST group (power-trained) = 15 probands FB group (playing football) = 9 probands. Results: I summarized the findings of anthropometry and 3D scanning with using literature. Statistical and real significance has shown differences between study groups, and therefore we can conclude that despite similar somatic composition are frictionally trained demonstrably more active muscle on the contrary, we found that the total mass We clearly does not affect the age, size, or percentage of fat that had little effect on intergroup comparison. This means that despite the diversity of sporting focus of the two...

Supplementation and nutritional strategies in artistic gymnastics
Černák, Ján ; Petr, Miroslav (advisor) ; Šteffl, Michal (referee)
Title: Supplementation and nutritional strategies in artistic gymnastics Objectives: The aim of this thesis is to bring a critical view of the current state of nutrition and supplementation in gymnastics, as well as suggest ways to optimize nutrient intake and supplements in practice. Methods: For research I used primarily the database of electronic resources PubMed, EBSCO, ScienceDirect, Ovid and others. Based on informations from the articles and the available literature I created this review. Results: Low energy intake, especially in gymnasts, can cause degenerative disorder to health (menstrual problems, impact on growth). This is connected with inadequate nutrient intake. The aesthetic factor and the strength to weight ratio play a major role in reducing energy intake in gymnasts. Supplements are used by approximately 58% of gymnasts, who take them to improve the performance and because of physiological demands. Keywords: energy intake, food intake, gymnastics

The correlation between the amount of fat in the abdominal area and the amount of visceral fat bioimpedance method recorded
Bundová, Petra ; Petr, Miroslav (advisor) ; Coufalová, Klára (referee)
Title: The correlation between the amount of fat in the abdominal area and the amount of visceral fat bioimpedance method recorded. Objectives: The aim is to verify the validity of the methodology for determining the amount of body fat in risky parts through bioelectrical impedance. Methods: To obtain data for the assessment of body composition were used bioelectrical impedance, skinfold measurement and somatometry. Results: The first hypothesis, assuming that the ratio between waist and hips, set somatometrical method, and the ratio of waist and hips measured by bioelectrical impedance will be a strong correlation was not confirmed. The second hypothesis, assuming that the amount of visceral fat, measured by bioelectrical impedance, and skinfold thickness in the waist area, there is a strong correlation is also confirmed. The measurement results showed that the measurement of visceral fat bioimpedance method is accurate and would probably be more beneficial to the measurement of the parts rather use skinfold measurement and the somatometry. Keywords: body composition, subcutaneous fat, visceral fat, bioelectrical impedance, skinfold measurement
