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

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...

Nutrition value of "Protein" labeled food
Knížková, Šárka ; Dostálová, Jana (advisor) ; Kudlová, Eva (referee)
This bachelor thesis addresses the issue of increased demand for foods with a high protein content on their packaging. The theoretical part describes the role of proteins in the body, their biological value, and it also names suitable sources of protein for the human body, including the protein content of common foods. There is a particular chapter dedicated to sportspeople and protein supplements. The requirements of the Czech legislation on food with a statement concerning proteins or the name protein itself are given at the end of the theoretical part. The bachelor's thesis aimed to find out the exact offer of foods with the protein label or with a claim related to proteins, evaluate these foods, and determine the awareness of such labelled foods in the general population. The practical part first deals with foods labelled with protein or claims about proteins freely available in the most standard supermarkets. The survey was conducted by visiting the six closest supermarkets while listing all foods with some protein claims. A total of 363 pieces were recorded. Furthermore, the most visited supermarket was evaluated with the help of registered sales and foods with the protein label found in this particular supermarket were analysed. The amount of protein of each food was commented on, and the...

Differences in adherence to nutrition recommendations based on prior education in youth football players at football academies
Wolfová, Nikola ; Suchánek, Pavel (advisor) ; Starnovská, Tamara (referee)
The diploma thesis describes the importance of education of young athletes in the field of nutrition. The theoretical part describes nutrition for children. It explains which macronutrients and micronutrients exist and why they are important for the child's body. Furthermore, sports nutrition for children and adolescents is discussed. Last but not least, the basic concepts associated with education, motivation and the influence of food on the mental and physical development of children and adolescents are explained. To meet the main purpose of this work, four goals were set. The first three goals are to compare two groups of boys. The first group of boys has been included in regional football academies for a long time and has been educated about proper nutrition in the past when joining the regional football academy and then in the following years. In the second group, the boys who come to the regional football academy are new, have never been instructed in proper nutrition before and will be educated for the first time. The comparison outlines whether and what is the difference between the results of body composition and diet of previously educated boys compared to those who were newly informed. The fourth goal was to verify whether and what is the importance of education and educational materials...

Impact of adequate energy and nutrients intake on growth and body composition of youth football players
Iliopulu, Margarita ; Hubáček, Jaroslav (advisor) ; Tomešová, Jitka (referee)
The main topic of my diploma thesis was to compare the changes in anthropometric parameters in relation to the diet composition of young footballers (soccer players) of the category U14 and U15 in the year 2017, year 2018 respectively, three months before entering the all-day regime of the Regional Football Academy at home and three months after that. The theoretical part focuses on the specifcs of the age U14 and U15 category, maps the nutritional needs for youth footballers in terms of nutritional, hydration and other important requirements, such as the timing of food. Next there is described the history and basic information about the establishment of the Regional Football Academies. The practical part works with the measured results based on regular anthropometric checks, body composition analyses, monitoring of body growth and information about daily food intake records on daily basis, which the football players recorded before entering academies. These daily food intake records were evaluated in the software BeetFit Pro. From the results of the diploma thesis it can be found that, for the successful changes of the anthropometric parameters and to manage demanding regimes within the region, it is necessary not only suffcient diet composition including the food timing, but major long-term and...

Nutrition of Czech Elite Marathon Runners
Gräfová, Martina ; Červinka, Pavel (advisor) ; Kaplan, Aleš (referee)
Title: Nutrition of Czech Elite Marathon Runners Aims: Theoretical part of this bachelor thesis summarises information on nutrition of endurance athletes. Practical part analyses dietary habits of Czech elite marathon runners. Objectives of this bachelor thesis were to survey if athletes are aiming at healthy dietary habits, how they maintain in pre-competition diet and whether they follow any of pre-event nutrition strategies. Methods: Research was completed by sending an electronical questionnaire to a representative number of Czech marathon runners before the 2020 event season. Results: Questionaire was completed by twelve elite marathon runners, out of this number six men and six women. Outcome proved the athletes are interested in their diet, especially before events when hydration is increased, yet carbohydrates and other nutrients are kept unchanged. Almost all respondents use food supplements not only before the contest but also during the year, commonly it is BCAA. Only 30 % of respondents is on super carb diet before the event. Approximately a week before the race they reduce the carb income of 20-30 %, however three to four days before the race they increase the carb income of 20-30 % above the usual numbers. Key words: sports nutrition, marathon, pre-event diet, carbohydrate loading diet

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...

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...
