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

Teplá, Jana ; Kovářová, Lenka (advisor) ; Coufalová, Klára (referee)
Title: Dietary Habits during Long Triathlon Objectives: The main objective of this thesis is to prepare alternative diets from three selected manufacturers offering sports nutrition. Another objective was to ascertain the eating habits of triathletes during race in long triathlon, and their comparison. Methods: We carried out determination of the eating habits of triathletes via a survey. Eleven triathletes on various performance levels participated in the survey. We ascertained in particular the amount of kJ, carbohydrates and volume of liquids intake during a race, the average of kJ, carbohydrates and volume of liquids intake per 1 hour of the race, the average of carbohydrates intake per 1 kg of the racer weight and 1 hour of the race, and then we compared these data with the recommended values. According to the recommended values and products of selected manufacturers, we prepared three diets with a schedule so that they suited sportsmen of 80 kg in weight who can finish the race under 5 hours. Results: 2 racers complied with the recommended values of kJ intake, 5 racers exceeded these values and 4 racers did not reach the values. 4 racers complied with the recommended values of carbohydrates intake, whereas 2 racers exceeded these values and 5 racers did not reach the values. The two fastest...

Červenka, Lukáš ; Kovářová, Lenka (advisor) ; Horčic, Josef (referee)
Tittle: Comparison of methods for identification AT via lactate curve in cycling Objective: Comparison of two negative split lactate tests performed on the indoor cycling trainer that determine the anaerobic threshold based on the lactate curve. Methodology: We chose two specific lactate tests for the comparison. The first one has been used for very long time in Czech Republic and it is so called progressive OBLA test. The second test is performed rather abroad and it is Pro Endurance Test Cycling. We made the comparison in the group of three people each with different level of fitness. The order of the tests was chosen randomly with time difference of 10 days. We used the application called Winlactat as a software for processing our data. Results: We can state on the base of the data gained from our testing that there are differences between results in both tests. However, these differences are closely dependant on the fitness of sportsmen as well as on the concrete parameters that we were analyzing. The first hypothesis was not confirmed due to the difference between some values, e.g. the person number 2 had a significant difference in the value of lactate during the aerobic stress going up to 31,8%. If there is someone with lower level of fitness the difference in his heart rate at the level of...

Fisenko, Ondřej ; Kovářová, Lenka (advisor) ; Daďová, Klára (referee)
Title: Comparison of subjective and objective perception of the swimming and the running fatigue of the elite triathlete on the level of aerobic and anaerobic threshold. Objectives: The objective of this work is to compare subjective and objective perception of the swimming and the running fatigue of the elite triathlete on the level of aerobic and anaerobic threshold and to assess a suitability of application of the subjective evaluation as one of the possibilities of control of the physical strain of the elite triathlete. Methods: The experimental studied team was created by the group of professional triathletes classified within the national team as category K23. The heart frequency was measured with heart rate monitor. The value of aerobic and anaerobic threshold was found out by means of Free Freiburg (Simon) using lactate curve. The subjective evaluation was made according to the Borg Rating of Perceived Exertion Scale. In order to appraise a statistical significance of the differences the pair t-Text was used. Results: It was found out, that the values of the Borg Rating of Perceived Exertion Scale do not show any significant difference between swimming and running or aerobic threshold (p=0.16) either anaerobic threshold (p=0.63). Any significant statistical discrepancy does not exist...

Zikmund, Jan ; Kovářová, Lenka (advisor) ; Horčic, Josef (referee)
Tittle: Curve- fitting of the critical power in swimming for triathletes Objectives: Comparison of curve-fitting of the critical power at swimmers and triathletes in different performance categories. Methods: This thesis is based on a research. The research took place in laboratories FTVS UK and there was used the swimming simulator called Biokinetic for test measurements. Elite swimmers, triathletes and hobby triathletes participated in the tests. Sportsmen took part in 4 tests. The first test - 10 crawl strokes, the second test - 20 crawl strokes, the third test - 50 crawl strokes and the fourth test - 200 crawl strokes. The obtained data were worked out by using T-test and they were written into tables and charts in programs Excel and Word. There was used program PASW Statistics 18 for statistical processing. Results: It was discovered, that there were no differences in performances in tests by using Biokinetic between swimmers and triathletes. Hobby triathletes made the same performances as elite triathletes. The biggest difference in performances was at female hobby triathletes, who were worse than female elite triathletes and female swimmers. Keywords: Critical power, swimming, triathlon, Biokinetic, testing
