Influence of cervical spinal cord lesion on cardiovascular fitness
Machač, Stanislav ; Kolář, Pavel (advisor) ; Vilikus, Zdeněk (referee) ; Nováková, Marie (referee)
Traumatic damage to the cervical spinal cord has a dramatic impact on determinants affecting cardiovascular fitness. In tetraplegia, in addition to diminished skeletal muscle function, impaired sympathetic cardiovascular innervation together with a dysfunction of catecholamine release is typically present. Individuals with tetraplegia are at a high risk of long-term inactivity, which increasingly contributes to the development of common civilization diseases. The aim of the current dissertation project is to investigate the cardiovascular fitness in males with cervical spinal cord injury (n=20) as compared to able- bodied males (n=27). Both groups completed exercise testing on an arm-crank ergometer. Arterial blood pressure response to exercise, peak oxygen consumption and peak heart rate were the primary outcome variables. In the first part of the study, a graded maximal arm- crank ergometer test to the subjective exhaustion was performed for the inter-group peak exercise comparison. The peak power dramatically differs between the groups and could be an important confounding factor limiting the evaluation of a physiologic response related to the equivalent physical loading. Therefore, in the second part of the study, individuals of the control group completed a second graded arm-crank ergometer...

Balušková, Denisa ; Vilikus, Zdeněk (advisor) ; Větrovská, Renata (referee)
The subject of the research and the research problem is the effort to evaluate the nutrition of extra-league hockey players and its comparison with the general population. The nutrition of an ice hockey player is usually not one of the most discussed topics in the field of sports, yet it has a great impact on sports performance. The goals were to compare the basic macronutrients, energy intake, number of meals or fluid intake. The theoretical part of the thesis is written about the characteristics of hockey and the nutrition of hockey players in the field of intake of carbohydrates, proteins, fats, drinking regime and supplements. In the practical part of the work is a quantitative research survey monitoring the diet of hockey players and its practical composition. A comparative method was used to compare the two groups, anthropometry for body analysis, online questionnaires for monitoring habits and recorded daily menus. It was important to note that most top players have limiting knowledge of nutrition issues. Education of elite athletes in the field of nutrition can ensure the development of their full sport potential.

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...
