The influence of 3-month exercise program on postural stability in individuals after bariatric surgery
Mašková, Kateřina ; Daďová, Klára (advisor) ; Vilikus, Zdeněk (referee)
Title: The effect of movement program on static postural stability in individuals after bariatric surgery Aims: The aim of this diploma thesis was to find out whether a three-month regular exercise program including strenght and aerobic training has an impact on static postural stability in obese individuals who underwent bariatric surgery. Methodology: The special part was written on the basis of data obtained from posturographic measurement of obese patients who underwent bariatric surgery. The static postural stability was measured using pressure plate a MobileMat from Tekscan. Participants were measured before surgery and approximately 4 months after surgery. A total of 30 subjects aged 31-65 years with BMI values between 35-55 kg/m2 (obesity class II and III) who underwent initial and exit examination including stabilometry, were included in this diploma thesis. They were divided into 2 groups, first group participating in a three-month exercise program (n = 10; age 51 ± 7.3 years; BMI 41.7 ± 6.4 kg/m2 ) and a group undergoing bariatric surgery only (n = 20; age 48 ± 9, 4 years; BMI 43.6 ± 6.5 kg/m2 ). The exercise program included exercise three times a week: once a week one-hour strength training and one-hour aerobic group training, and at least once a week home intervention. Results: In...
Influence of caffeine on strength performance
Jílková, Anna ; Vilikus, Zdeněk (advisor) ; Petráková Doležalová, Radka (referee)
This bachelor thesis is divided into theoretical and practical part. The theoretical part is divided into several chapters which deal with general properties of caffeine, its structure, metabolism, occurrence and effects on human organism. A special chapter deals with sports issues and the use of caffeine in sports. The practical part includes individual research into the influence of caffeine on the strenght performance and on the human organism. The aim of this work was to find out whether caffeine shows ergogenic effects at a strenght performance of 1 RM. For this, an experiment was used in which the participants underwent two tests, in one using caffeine 3 mg / kg body weight, in the other using placebo. The challenge was to lift as much weight as possible for one maximum repetition (1RM) in bench press and deadlift exercises. A total of 24 people, 17 women and 7 men with an average age of 27 years and an average BMI of 23.8 underwent the experiment. The test results showed an average improvement of 2.3 kg for deadlift and 0.3 kg for bench press. However, these values are not statistically significant (p = 0.253 and p = 0.775). Key words: caffeine, strenght performance, dietary suplements, deadlift, bench press
Problematics of mountaineers' nutrition
Honzejková, Kateřina ; Vilikus, Zdeněk (advisor) ; Vágnerová, Tereza (referee)
Nutrition of both professional and occasional climbers in high altitude is often discussed topic in sports nutrition. Specially with latest studies showing connection between poor nutrition and high altitude sickness development. Dehydration in particular has a huge effect on the body at these altitudes and can be responsible for many of the symptoms previously attributed to hypoxia. The research was focused on the theoretical part, in which basic issue of nutrition and hydration are shown, as well as the acute issues that climbers may have experience on their journey to high altitude. The practical part was evaluated by a quantitative approach with the help of a questionnaire survey and its evaluation. The questionnaire was anonymous, nonstandardized with open and closed questions. A total of 68 respondents participated in the research. The results of the investigation are evaluated and discussed in the final parts of the thesis. The main objective of the thesis was focused on the dietary habits of respondents during their stay in high altitude, their awareness of the risks resulting from poor nutrition and dehydration and assess how much care respondents take about nutrition and hydration during their travels. Four hypotheses were set for the thesis. Key words: Nutrition; hydratation; acute...
Diabetes mellitus in equestrian sport in Czech Republic
Mašková, Marie ; Vilikus, Zdeněk (advisor) ; Vařeková, Jitka (referee)
Title: Diabetes mellitus in Equistrian Sport in Czech Republic Objectives: The aim of the literature review part of the thesis was to give an introduction to the issue of diabetes mellitus as well as the effect of sport on the decompensation of the disease, to search for available sources on a narrowly focused topic - the impact of horse riding on diabetes mellitus, and to process the findings in a clear form into the first (literature review) part of the work. The goal of the second (research) part was to map, with the use of questionnaires and interviews, the situation of diabetes patients in the Czech Republic who do equestrian sport actively. In the case study their subjective feelings were reviewed. The main aim was to prove the positive impact of horse riding on diabetes mellitus, or more precisely to find out if it is stress or physical exertion that has a greater effect on the blood glucose (BG) level. Furthermore, the thesis focuses on the issue of public awareness of disease management as well as first aid. Methods: The first part of the thesis was carried out in the form of a literature review, for which research articles and other literature sources were found primarily on electronic information portals (mainly Web of Science, etc.) For the second (research) part a questionnaire (on the...
Issues of nutrition and doping in bodybuilding and fitness
Linhartová, Gabriela ; Chrástková, Martina (advisor) ; Vilikus, Zdeněk (referee)
Title: The problems of nutrition and doping in bodybuilding and fitness Purposes: The aim of the thesis was to find differences in the area of nutrition and doping in condition fitness exercisers, active amateur competitors and professional athletes in bodybuilding and fitness, in the area of macro nutrients intake, drinking regimen, dietary supplements and abuse of doping. Methods: For the research, the qualitative method was chosen as a survey. The survey is divided into questions identifying information about problems of nutrition and doping. It contains a combination of open, closed and semi- closed questions. The selected set of examinations was a random sample of condition fitness exercisers, amateur and professional bodybuilding and fitness athletes. Results: The survey shows that although condition fitness exercisers perceive the optimal macronutrient and micronutrient intake, drinking regimen and dietary supplements as part of success in bodybuilding and fitness, their awareness and discipline do not reach the same level as competing respondents (amateurs and professional athletes). The diet of the competitors corresponds more with the recommendations in the literary sources. Minimal differences were found between the nutrition of condition fitness exercisers and athletes (amateur and...
The effect of MCT on endurance performance
Holá, Kateřina ; Vilikus, Zdeněk (advisor) ; Brandejský, Petr (referee)
MCT oils are triglycerides whose fatty acids have an aliphatic tail of 6-12 carbon atoms. Within the gastrointestinal tract, MCT are digested to their respective fatty acids (MCFAs) and rapidly absorbed and transported into the portal vein which then takes them straight to the liver, therefore MCTs are not stored in fat deposits in the body as much as LCTs. In addition, MCTs can pass through the mitochondrial membrane of the liver and muscle not depending on the carnitine transporter, what makes them a very readily available source of energy. Endurance athletes try to maximize their ability to mantain glycogen stores during exercise, so that using these supplements as a quick source of energy should lead to improved endurance performance. The aim of the work is to provide a more objective view of the prevailing trends and different conclusions of particular scientific studies and to clarify the impact of MCT on sport endurance performance. The work includes meta-analysis based on data collection method from previously published scientific studies following the use of MCTs in relation to sport endurance performance. Medical database PubMed and multidisciplinary databases EBSCO and Google Scholar were used to search for these studies. The meta-analysis does not show any specific effect of MCTs...
Nutritional indicators of performance triathletes
Skuhrová, Tereza ; Vilikus, Zdeněk (advisor) ; Matoulek, Martin (referee)
This bachelor thesis is aimed to find out nutrition indicators of performance triathletes and to compare them with non-sportsmen. The next aim is to point out the importace of proper balanced diet in endurance sport and to evaluate the usage of food supplements. This thesis is divided into two parts, a theoretical part and a practical one. Main individual nutrients are described in the theoretical part in connection with energy metabolism and with emphasis on influence of nutrition in triathlon. The practical part summarizes results obtained from an analysis of a four-day nutritional intake of 8 performance triathletes and 8 non-sportsmen. A range of the respondents' age was between 26 and 37 years. The results point out that both groups have higher energy intake than recommended rate. Both groups' intakes of proteins and fats of animal origin are approximately twice higher than recommended as well as their results of micronutrient intake are not balanced. Furthermore, a brief questionnaire shows that 50 % of respondents were not satisfied how they can gain information about nutrition, at the same time 54 % use the internet as a main source of information and only 13 % read a scientific literature. Key words: triathlon, sports nutrition, endurance performance, food supplements, drinking regime
Caffeine and its influence on sports performance
Kadlecová, Nikola ; Vilikus, Zdeněk (advisor) ; Tuka, Vladimír (referee)
This bachelor thesis is composed of theoretical and practical part. The first section focuses on characteristics and history of caffeine, its effects on different parts of the body, description of sport activity, and matters of using caffeine as a form of doping in sports. On the basis of the theoretical foundation, I have composed practical part where research project is described. The project consisted of observation of the effects of caffeine during medium- term endurance activity. The aim of this thesis is to discover how consumption of caffeine before a sport activity can affect performance of an individual. For that purpose, I have used an experiment which should determine if caffeine improves performance in 1,500-metre run. The experiment involved 16 people 25.6 years old on average and with average BMI of 24. The testing included test run without the consumption of caffeine and run with caffeine when 1 hour before the run the participants got caffeine of total dosage of 3 mg/kilogram of their weight. After the comparison, the results showed that 10 people had better performance after consumption of caffeine, and overall there was 3,5-seconds improvement. Nevertheless, the results are not significant according to statistical assessment (p=0,306), and therefore caffeine did not support the...

Nutrition at sports with weight categories
Žabová, Anna ; Vilikus, Zdeněk (advisor) ; Tuka, Vladimír (referee)
This bachelor thesis is focused on diets in sports with weight categories. The main goal is to find out about the diets of the professional athletes before the official weighting, what methods of weight reduction these athletes use and whether they experience any negative effects of the diet on their health. Theoretical part focuses on the information about weight categories, nutrition recommendations for particular athletes, forms of weight reduction and human body composition analysis. The practical part is divided into two researches. The first research is carried out in the form of a quantitative questionnaire, in which the respondents provide information on dietary habits and their presence in the weight category. The second research focuses on five light-weight rowers, whose body composition information is compared in the non-competitive and competitive period. The questionnaire has been filled in by 103 competitors from 9 different sports with weight categories. Some outputs are quite worrying, or even alarming. Only less than one third of the respondents races in their category without major weight fluctuations or greater dietary restrictions. Comparing the data from both measurements of the body composition of the athlete (out of season and before the race) turned out as expected with only...
