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.

Women in strength sports.
Světelská, Denisa ; Országhová, Kristína (advisor) ; Pergl, David (referee)
The bachelor thesis "Women in strength sports" deals with a qualitative analysis of self- concept of women participating in strength sports, weightlifting and CrossFit. Using semi- structured interviews and based on the accounts of these women's experiences, a self-image of women in strength sports was created. The aim was to explore the experiences of women in strength sports and how they perceive themselves. Through their personal experiences, the thesis seeks to identify factors that may influence their perceptions. The analysis also focuses on the normative perceptions of women in strength sports. Attention is also given to media representation and equality in strength sports competitions.

Change in bodyweight and body composition during the weightlifting training unit and nutrition in strength sports
Vašků, Karolína ; Matoulek, Martin (advisor) ; Petráková Doležalová, Radka (referee)
This bachelor thesis monitors changes in body weight and body composition during training in professional athletes, three women and four men, from the Czech weightlifting team. The theoretical part describes components of the body composition, basic methods and calculations for its assessment. In addition, energy substrates used in weightlifting and sport nutrition basics, including suitable supplements for power athletes, are mentioned. In the practical part, using the bioelectric impedance device, we evaluated the actual body composition and energy needs of individuals in a series of three defined measurements-before training, after training, and after meals. The results of our qualitative research confirm that the energy needs of power athletes are far higher than predicted. We compared the minimum caloric requirement values obtained with the In Body 230 device measurement to those obtained using the Harris-Benedicts predictive equations (HBE), and pointed to significant deviations in basal metabolism calculations and inaccuracy of the results obtained with this equation. In most cases, with HBE, we have experienced undervalue in comparison to the In Body measurement. We have also confirmed the fact that the BMI is not suitable for the weight loss evaluation in weightlifters because of the...

Analysis and comparasion of squat exercise due to surface EMG
Orava, Boris ; Kračmar, Bronislav (advisor) ; Jebavý, Radim (referee)
ABSTRACT Title of dissertation: Analysis and comparasion of squat exercise due to surface EMG Objectives of dissertation: To measure and describe the structure involving specific muscles durring back squat, front squat and smith machine squat exercise. Method: Surface EMG analysis and simple kinematic analysis. Results: Activation of m. gluteus maximus was highest after the start of excentric movement. Main muscle working on the chase between the concentric and excentric movement was m. rectus femoris. Very similar timing and synergy were between m. erector spinae and m. biceps femoris. In this study was not higher activation of m. quadriceps femoris during front squat exercise, activation of m. gluteus maximus were also higher. Key words: squat, strengthening, bar, front squat, back squat, Smith machine squat, bodybuilding, weightlifting, powerlifting, EMG analysis, kinematic analysis 6
