Kekrtová, Magdaléna ; Vilikus, Zdeněk (advisor) ; Větrovská, Renata (referee)
This bachelor thesis deals with the issue of eating disorders (ED) in gymnastics. Eating disorders are serious mental illnesses that occur especially in adolescent women. Gymnastics, as a sport with an emphasis on aesthetics, is risky in terms of ED, it affects the occurrence of a large number of risk factors that affect gymnasts. The theoretical part of the bachelor thesis generally summarizes the individual diagnoses of eating disorders, risk factors, incidence and prevalence, health complications, treatment and disease prevention. These general findings are supplemented by the current state of knowledge of eating disorders from the gymnastic enviroment. The second half of the theoretical part introduces the principles of energy metabolism and healthy nutrition. The practical part consists of quantitative research, carried out using a questionnaire, which was imaginarilly divided into two parts. The first half of the research examines gymnasts' attitudes to nutrition and diet, and the second half examines ED in gymnastics. Due to the absence of males, the research results can only be applied to women. Research confirms the frequent occureence of risky behavior among gymnasts, the popularity of reduction diets, low body weight or high ambient pressure, which is mainly caused by coaches. Research...
Fitness center clients nutrition focused on protein and magnesium intake
Pajič, Barbora ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
The diploma thesis deals with the importance of protein and magnesium in the diet of recreational visitors to fitness centers. Excessive protein intake at the expense of other macronutrients is a very common phenomenon in the fitness sector. Magnesium is an important element for muscle regeneration and its deficiency can have a negative effect on weight reduction and muscle gain, leading to fatigue and cramps, which many athletes encounter. As visits to the fitness center become more and more popular nowadays, it is important that athletes are not subject to misleading and confusing information from the internet and look for proven sources. The aim of the diploma thesis was to compare eating habits, especially protein and magnesium intake, in two groups of people divided according to the frequency of training in the fitness center. This work is divided into theoretical and practical part. The theoretical part deals with nutrition in the fitness industry in general, but more attention is focused on proteins and magnesium. Quantitative research using a questionnaire survey was chosen for the practical part of the work. A total of 30 respondents participated in the research, divided into two groups - athletes and non-athletes. Non-athletes were considered to be those who have two or fewer workouts per...
Nutritional specifics in OCR
Lišková, Lucie ; Vilikus, Zdeněk (advisor) ; Větrovská, Renata (referee)
This bachelor thesis deals with the nutrition of competitors in the obstacle sport known by the abbreviation OCR. The main task of this work is to describe the importance and significance of sports nutrition and its timing in this strength and endurance sport and consequently compare the diet of OCR competitors with nutritional recommendations for this sport. The aim of the work is to determine what awareness competitors in this sport have about sports nutrition and whether their energy intake is sufficient. The method of evaluation of the dietary record was used for the solution, to which a short questionnaire on the characteristics of the athlete and his training was attached. The research group consisted of 12 competitors (5 women and 7 men) in the age range of 19-33 years. Through research, I found that energy intake was not sufficient for both women and men. The average daily energy intake for women was 8,076 kJ, which corresponds to 83% of the recommended daily intake for this group of women, for men this average intake was 10,519 kJ, i.e. 82% of the recommended standard. In particular, carbohydrates played a key role in inadequate energy intake, their amount being significantly lower than recommended in both sexes. Based on quantitative research, I can say that OCR competitors do not have...

Kadlecová, Nikola ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
The theme of this thesis is sports diet. It is divided into two parts. A theoretical part explains balanced died. It describes the mechanics of energy generation during physical activity and the characteristics of rowing and Crossfit. The focus is on diet in those disciplines. Based on the theoretical foundation is build a practical part, where the statistical data are analyzed and evaluated. The goal of this thesis is to discover, whether there is a difference between rower's and Crossfit athlete's diets. To find out, specialized questionaries about eating habits have been used. Sixteen sportsmen/sportswomen have filled the questionaries. Based upon collected data about their intake of selected nutrients in the last month, there were no statistically significant differences in energy income, protein consumption (neither animal nor plant-based), amount of fruit and vegetables, fatty acid spectrum nor added sugar income. The data have nonetheless indicated differences, eg. Crossfitters tend to have higher animal protein consumption and lower intake of fruit. Key words: crossfit, eating habits, nutrition, rowing, sport diet

The effect of carbohydrate mouth rinse on endurance performance
Stuparič, Jan ; Vilikus, Zdeněk (advisor) ; Větrovská, Renata (referee)
This bachelor thesis is focused on the effect of carbohydrate mouth rinse (CMR) on endurance performance. CMR is considered to be one of the effective nutritional strategies that increases endurance performance in duration from 30-90 minutes. The aim of this thesis was to determine whether CMR can improve performance in a running 30-minute test with self-selected pace and set rate of perceived exertion. All of that without any prior significant influence on nutritional status. Two trials were realized - with and without CMR. Total distance covered during a stated time period was compared, as well as the rate of subjective feelings during the physical activity in the sense of pleasure-displeasure using the Feeling scale. The heart rate was compared as well. Under specified conditions the ergogenic effect of CMR was not confirmed, on the contrary 6 of 8 participants performed worst in the trial with CMR compared to one without CMR. Five participants mentioned enhanced feelings of pleasure to some extent, but the differences were minimal. Regarding heart rate little difference were indicated in the case of average heart rate, when higher values were detected in six participants. However, overall significant effect of CMR on heart rate was not shown. For the efficient implication of CMR into the...
Eating disorders at ski jumping athletes
Ptáčková, Veronika ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
In my bachelor's thesis I have been dealing with a risk behavior in the field of nutrition of Czech men and women ski jumpers. The goal of the bachelor's thesis was to find out whether Czech men and women ski jumpers maintain their physiological weight, whether they use inappropriate practices (for example, induction of vomiting) in the context of weight loss. I also investigated whether there is an effort of the International Ski Federation to reduce the risk of eating disorders among athletes engaged into this discipline. In the theoretical part of this bachelor's thesis, I focused on individual types of eating disorders, risk factors for their occurrence, health complications associated with eating disorders or the epidemiology of these disorders. Furthermore, I focused on the ski jumping itself, explained the rules, especially those concerned about the weight of jumpers. I found out how important is the weight of the jumper in the final length of his jump. I also focused on the development of body weight of professional ski jumpers. The practical part was realized in the form of own designed non-standardized questionnaire. The questionnaire was filled in by 49 respondents, 17 women and 32 men. According to the BMI, a third of respondents are underweight, more often women (55 % of women). A...

Ančincová, Kateřina ; Matoulek, Martin (advisor) ; Vilikus, Zdeněk (referee)
Thesis title: Evaluation of postural stability and postural strategy in obese people Objectives: The main objective was to evaluate postural stability using computer posturography in obese people and assess whether three-month exercise training with a focus on sensorimotor stimulation has an effect on postural stability. Methods: This is a cross-sectional experimental study. The research group consisted of 20 probands aged 30 to 62 years with BMI values of 31.1-53.5 kg / m2, from which the general posturography was evaluated. The effect of sensorimotor training was subsequently assessed of 13 probands, who were divided into two groups - interventional (n = 6) and control (n = 7). The measurement was performed using static computer posturography and computer goniometry processed by the freeStep software system. To compare the effect of sensorimotor training, measurements were performed twice in the intervention and control groups, over a period of approximately three months. Postural stability was evaluated based on the Sway test. Statistical analysis was performed using IBM SPSS Statistics 24 software. Statistical significance was determined at the level of α = 0.05, the result where p <0.05 was considered statistically significant. Results: General posturography in the research group showed a...
