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.

Informations and use of suplements in bodybuilding of young beginners and advanced bodybuilders.
PROCHÁZKA, Jakub
This bachelor thesis deals with dietary supplements and their use in practitioners on both amateur and semi-professional levels. The main goal is to map out the overall usability and awareness of fit center visitors. In the first part, the theoretical part of the thesis is devoted to food supplements, their forms and division. In the second part were selected substances that are used as supplements in exercisers and further analyzed in terms of their function and effects on the body of the athlete. The research itself was conducted in the form of an anonymous questionnaire survey, which was sent to respondents electronically. The questionnaire was created on google.com and distributed in both electronic and printed form. Respondents were searched in several ways. Personal sports contacts were used to fill in and distribute questionnaires and send questionnaires to various sports clubs. The survey itself was attended by 263 respondents. The main goal of mapping the use of food supplements has shown that respondents have some information gaps in the effects of different types of food supplements. In addition to the main goal, four hypotheses were also confirmed, which were subsequently confirmed after data collection.

Importance of nutrition, mainly proteins, in power sports.
Šesták, David ; Bláha, Pavel (advisor) ; Martinča, Jozef (referee)
Heavy athletics is a great stress for a human organism. This stress has to be compensated by proper nourishment and proper relaxation. Higher intake of all nutrients is always linked to heavy athletics. Some nutrients, such as omega-3 fatty acids, iron, zinc and proteins have a unique role in strength disciplines. Especially proteins are considered by both amateur and professional athletes as the most essential for muscle building. It is questionable how much protein is needed and how does its quality (directly linked to digestibility and absorbency) differ in animal and plant proteins, or even in supplementations proteins. The types of nourishment proteins that are combined together and what type of training is preferred matter significantly. Other agents of high significance are evidently, with direct or indirect influence, carbohydrates, dietary fiber, fats, vitamins, minerals and drinking habits.
