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.

Possibilities of physiotherapy of muscle disbalances among weightlifters
VLASÁK, Martin
The Bachelor's work deals with the topic of muscle disbalances among weightlifters from physiotherapeutic point of view. Due to influence of complex motion pattern's are muscles forced to work in perfect coactivation. As a result of this fact the muscles are much more inclinable to muscle disbalances. Muscle disbalances are created as a result of asymmetric, one-sided and inappropriate load of musculoskeletal system. This pathology can leads to lesion of structure or have a negative impact on the weghtlifters performance. We can include a compensation exercises as a prevention of musculoskeletal overload. The aim of this work is to present the problems of muscle disbalances among weghtlifters from the physiotherapeutic point of view and to offer possibilities of physiotherapeutic methods for prevntion of injuries. The theoretical part describes muscle disbalances. This work describes patomechanism of creation muscle disbalances, their relationship with pain and their sorting to most common clinical syndromes. Furthermore, the issues of weightlifting, the movements and basic exercises are described. The theoretical part also describes examination and physiotherapeutic methods. This fullfils the first aim os the bachelor's work regarding muscle disbalances among weghtlifters. The praction part of bachelor's work is processed by the quality research method. For analysis, the case interpretation of three weghtlifters who are in training proces for they firs weightlifting meet. Every case interpretation involves input and output kinesiological analysis that have eleven parts: complex anamnesis definition, static inspection of aspection and palpation, somatometric inspection, function muscle test, dynamic inspection for spine and lateral pelvis stabilizers, inspection of movements stereotypes, activity of deep stabilization system of the spine, hypermobility tests and shortening of muscle groups tests. Within this therapy, soft tissue techniques, method of dynamic neuromuscular stabilization, Dr. Brügger's concept, exercises wiht thera band, have been used. Based on analysis of obtained data, both, the short-term and long-term individual kinesiotherapeutical plan for all three weghtlifters, has been made. Due to this step the second aim of the bachelor's work was fulfilled, because work show the possibility of particular physiotherapeutic methods for prevention of injuries. The therapy results are positive and confirm selected physiotherapeutical methods as an effective tool against muscle disbalances not just for weightlifters. The deep stabilization systém of the spine has been improved with all three weightlifters also better muscle coactivation as well as reduction of limiting factors could be observed. He bachelor's work can be used by physiotherapists, coaches and even by athletes as a prevention of injuris and improvment of their performances.

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
