Havlová, Ivona ; Kimmer, David (advisor) ; Šimková, Simona (referee)
Nutrition and Supplementation in Fitness and Bodybuilding Abstract The topic of this master's thesis is "Nutrition and Supplementation in Fitness and Bodybuilding". Physical fitness is getting more and more popular and becoming a global industry. Young people tend to prefer gyms to other types of physical activities. The advantage of fitness workouts is that there is no age limit, provided the person is healthy, as evidenced by exercising individuals who are 15 years old but also senior citizens over the age of 65. The empirical part of the paper was conducted using a qualitative method, gathering respondents through snowball sampling where participants identify others. As many as 28 respondents were divided into two groups: people doing conditioning and bodybuilding whose characteristics are explained in the Operationalisation chapter. All respondents did a semi-structured interview and provided a three-day diet plan. The goal was to map eating habits and the most common diet plans of people doing conditioning and bodybuilding, and to discover supplements they use the most frequently. The practical part of the thesis focused on the most frequent diet plans and supplements in fitness practitioners. The research findings indicate that the most common diet is high in protein and carbohydrates and low in fat,...

Food supplements in strength sports
KLEČKA, Jan
In this bachelor's thesis on Dietary Supplements in Strength Sports, I investigated whether elite athletes are able to consume sufficient nutrients without dietary supplements and what types of dietary supplements are used by strength athletes. I chose the respondents from three branches of strength sports, those sports are power triathlon, strongman sport and weightlifting. These are the leading athletes in these sectors in the Czech Republic and they are able to outline to me the topic of taking dietary supplements. The theoretical part is focused on the nutrition of athletes. In each section I have discussed a description of strength sports, including the history of strength sports, then I have discussed macronutrients, micronutrients and also the issue of dietary supplements, where I have described the history of dietary supplements and also their distribution. In the theoretical part I drew from books and professional journals. For the practical part of the thesis I set three objectives. The first objective was to map what types of dietary supplements are used by strength athletes, the second objective was to map what amounts of dietary supplements are used by strength athletes, and the third objective was to determine if a regular and complete diet provides the necessary amount of energy and individual nutrients. Ten athletes participated in my research, 9 men and 1 woman. I obtained data from them through a semi-structured interview and from their dietary records. The results show that the respondents are taking 10 types of supplements and 6 out of 10 respondents are able to take sufficient energy from their regular diet. The dietary analysis shows that respondents prefer a diet higher in fat and protein at the expense of carbohydrates, where a higher proportion of fat in the diet reduces the amount of food needed to meet the respondents' energy needs. It can also be observed that respondents do not place much emphasis on fibre intake.

The effect of MCT on endurance performance
Holá, Kateřina ; Vilikus, Zdeněk (advisor) ; Brandejský, Petr (referee)
MCT oils are triglycerides whose fatty acids have an aliphatic tail of 6-12 carbon atoms. Within the gastrointestinal tract, MCT are digested to their respective fatty acids (MCFAs) and rapidly absorbed and transported into the portal vein which then takes them straight to the liver, therefore MCTs are not stored in fat deposits in the body as much as LCTs. In addition, MCTs can pass through the mitochondrial membrane of the liver and muscle not depending on the carnitine transporter, what makes them a very readily available source of energy. Endurance athletes try to maximize their ability to mantain glycogen stores during exercise, so that using these supplements as a quick source of energy should lead to improved endurance performance. The aim of the work is to provide a more objective view of the prevailing trends and different conclusions of particular scientific studies and to clarify the impact of MCT on sport endurance performance. The work includes meta-analysis based on data collection method from previously published scientific studies following the use of MCTs in relation to sport endurance performance. Medical database PubMed and multidisciplinary databases EBSCO and Google Scholar were used to search for these studies. The meta-analysis does not show any specific effect of MCTs...

Substance abuse among the top bodybuilders in the Czech Republic
Hoffmanová, Jana ; Harsa, Pavel (advisor) ; Šejvl, Jaroslav (referee)
In the last few years, the interest in bodybuilding has increased but unluckily it is often accompanied by taking doping substances. At this time, we have been already informed about anabolic steroids exclusively through the media spreading the news about the doping scandals of top athletes. Although many books were written about doping and bodybuilding, their first publishing was dated to 2000 and the literature today mainly focuses on nutrition and training. The goal of my thesis was to map the view of top bodybuilders on doping at the professional and hobby level and their knowledge of the effects of prohibited substances. The qualitative research was made by the series of dialogues that were semi-structured and with the agreement of respondents. The information was recorded on a dictaphone, transcribed and edited. The main research questions were based on the risks that are bodybuilders aware of, their motivation for the sports and possible use of the prohibited substances. They were also asked about their experience of the addiction to them. According to the research, the athletes are well-informed about all the risks. The majority of them are regular users of excessive amount. The motivation for the bodybuilding and taking doping is different, but they have something in common. It is the...
