Reálný příjem živin u sportovců v odvětví kulturistiky a fitness v průběhu předsoutěžní přípravy
Bílková, Aneta
This diploma thesis „Real nutrient intake among bodybuilding athletes during competition preparation“ examines the nutritional habits of male and female bodybuilders. The theoretical part describes energy metabolism, nutrients, nutritional supplements and frequently used diet approaches. This thesis brings up the latest scientific recommendation adressing the topic. Last but not least, it approximates the specifics of bodybuilding. The practical part consists of evaluation of a questionnaire spread among athletes in bodybuilding and fitness. The results show that competitors consume protein in excess of the general recommendations, they do not reach the recommended intake of carbohydrates, dairy products, legumes and fruit. The positive findings are the intake of high quality protein, vegetables, a sufficient water intake, preferences for whole grain foods, plus low intake of animal fats and sugar. The most used supplement was protein powder. There was statistically significant (p < 0,05) dependence between the low energy availability and menstrual cycle dysfunctions among female competitors. There was no statistically significant (p > 0,05) dependence between competitive experience and dietary strategies during preparation among competitors.

Nutrition in sports fencing
PAPPOVÁ, Ester
The bachelor thesis focuses on Nutrition in sport fencing. First of all, in the theoretical part, sport fencing is described in order for the reader to learn more about this discipline. Next, the thesis illustrates nutrition in sport. Macronutrients and micronutrients are explained in detail. Since fencers wear many layers of fencing clothing, drinking is also included. This work also mentions atypical days in terms of fencers' diet. This is particularly the case during fencing competitions, when it is not possible for individual athletes to indulge in a proper diet, and they are forced to substitute in other ways. Most often they choose so-called fast carbohydrates or special sports foods. The aim of the bachelor's thesis was to identify, clarify and compare the nutritional habits of fencing athletes in the training and competition phase, including clarification of their attitudes towards following the principles of healthy nutrition in sport, and possibly suggest changes in their eating habits. Thus, the research population consisted of fencers in sport fencing. A quantitative research method was used. Data were collected using a questionnaire and dietary records. These were randomly evaluated in the program "Nutriservis professional" and then in Microsoft Excel the obtained survey results were tabulated. The questionnaire was distributed to 20 respondents and contained 57 questions. Their eating habits during the separate phases of training were thus more comprehensively investigated. The results were processed in the form of graphs in Microsoft Excel. The results show that the diet of sports fencers is not quite perfect. Although the principles of healthy nutrition recommend these foods, dairy products, whole grains, fish, and nuts are very often missing from the diet. Fruits and vegetables are also under-consumed, and many fencers eat fast food or drink sugary drinks.

Abstract The first part of this diploma thesis "Medium Chain Fatty Acids in Sports Nutrition" focuses on a literature research of topics regarding rational nutrition and its history, the importance of fats in nutrition, a more detailed review of fats in sports nutrition. It also describes the impact of medium-chain fatty acids (MCTs) on the human body and on performance in sport. The practical part of the work focused on the design of a suitable methodology for the determination of fatty acids and the analysis of available MCT-containing dietary supplements by using gas chromatography. Based on the measurement results, the fatty acid profile of the samples was evaluated, a statistical evaluation was performed and the measurement results were compared with the nutritional information of the products as labelled on the product packaging. The diploma thesis also included a questionnaire that was designed for a general audience in order to determine the knowledge of supplements and the popularity of dietary supplements containing MCTs. The aim of this thesis was to provide as comprehensive an overview as possible of medium chain fatty acids and their impact in sports nutrition by using a various information sources, and to determine whether respondents had an overview of MCTs based on the questionnaire and to conduct an analysis of fatty acids in MCT-containing products.

Nutritional deficiences in vegan endurance athletes
Knížková, Šárka ; Heniková, Marina (advisor) ; Koudelková, Kateřina (referee)
Aim: This study aimed to investigate whether vegan endurance athletes, specifically runners, experience nutritional deficiencies due to a purely plant-based diet. Partial goals were set to evaluate whether these athletes have sufficient energy intake and receive adequate macronutrients and risky micronutrients. Methods: The research was conducted as a pilot study for the extensive European project VEGANScreener. Based on the completed questionnaire and meeting the criteria, 11 participants (n = 11) were selected. The subjects underwent body composition analysis using bioimpedance, their resting energy expenditure was measured by indirect calorimetry, and blood was taken. The subjects then performed a 4-day food record (self-reported 4-day Dietary Record), which was analysed using new software. The complete dietary record was analysed for only eight subjects (n = 8). Nutritional data were analysed using the left-sided Mann- Whitney U test, which belongs to the group of non-parametric tests. The test was conducted at a significance level of α = 0.05. Results: The average BMI of the subjects was 20.87 ± 1.58 kg/m2. Two subjects (n = 2) had a lower body fat percentage than is adequate. The biochemical blood test results indicated a possible vitamin D and iron deficiency. When comparing actual energy...
