Comparison of results of spiroergometry on running and bicycle ergometer of elite regional triathletes
VÁŇA, Jan
The main aim of our work was to compare adolescent and adult elite triathletes from the South Bohemia region based on the results from the spiroergometry testing on the treadmill and bicyle. All of the tests were performed in the Lab of functional stress diagnosis at the KTVS PF JU. The testing parameters included the values of VO2max, tidal volume, minute ventilation, respiratory rate and the percentage of a body fat. Stress test were performed thanks to running ergomerer Cortex metacontrol 3 000 and a bicycle ergometer LODE Excalibrum Sport. The Tanita BC 481 MA is a bioimpendatory machine that was used to get informations about a body composition. One of the monitored values was the level of VO2max which was higher in adolescents than in adults. The values in the adults were 67,8 ? 6,3 ml.min-1.kg-1 on the bicycle and 69,2 ? 4,9 ml.min-1.kg-1 on the treadmill. In other monitored ventilation parameters, except a tidal volume on the bicycle, we measured higher values in the adults. The vaule of the VO2max was higher in the both categories and for this reason we suppose that triathletes are rather more runners than cyclists. The next thing we came up to is that the differences of the VO2max values are lower in the triathletes than in the runners and cyclists. The adolescent triathletes from the South Bohemia region have higher values of the VO2max than the adults despite their incomplete physical development.

Title: An observation of varying performances of triathletes based upon gender and age in the sport of Iron Distance Triathlons. Objectives: The goal of the thesis is to compare the results of the swim leg in the Ironman World Championship. We will be working with thirteen age groups compiling of 18 - 80 plus year old participants as well as both genders, male and female to gather our results. Our plan is to process results from the years 2005-2014, which is exactly 10 years or one decade. Method: Our method for gathering the results was a multiple analysis that complied a breakdown of the swim portion of an Iron Distance Triathlon for all Age Groups during those specific years. Results: After extensive research analyzing data, comparing data and studying past performances, we found that the participants times in the swim portion of Ironman Triathlon World Championships showed small significant differences over the past ten years. With minor deteriorations or improvements, swimming performances were seen at a consistent level for male and female age group 25-40. Men in the age group 18-54 showed improved outcomes over the women's same age group by 6-15%. In age groups ranging from 55- 80+, swim times increased by 15%. Overall the age groups with the most significant fluctuations in swim times was...

Title: EFFECTING EXERCISE REGIMEN OF CHILDREN AT YOUNGER SCHOOL AGE An alternative form of triathlon contest as a possibility to build a positive relationship to physical activity in children Objectives: To compare motion and diet patterns and basic parameters of body constitution in selected children divided into two groups: a random population and a population of children devoted to a specific physical activity - triathlon. The aim was to focus on contests organization and management, identify its weak points and suggest a suitable alternative with the ambition to bring children closer to any of disciplines triathlon is consisting of or to triathlon itself in a longtime fashion. Methods: Body height and weight measurements, BMI calculations. Questionnaire survey. Arrangement of a triathlon contest in its new alternative way. Evaluation. Results: A group of children actively doing triathlon shows more balanced distribution of body weight in comparison with data obtained when measuring random children during PE lessons at schools where cases of obesity and underweight were found. Triathlon contest model based on adult category is not convenient for children at younger school age considering their development characteristics. Arrangement of a non-competitive triathlon contest confirmed its positive...

Comparison of nutrition of swimmers and triathletes in childhood
Schovalová, Tereza ; Vilikus, Zdeněk (advisor) ; Větrovská, Renata (referee)
1 Abstract This diploma thesis is aimed to find out and compare nutrition indicators of young swimmers and triathletes. This thesis is divided into two parts, a theoretical part and a practical one. Main nutrients of the children diet are described in the theoretical part. This first part contains the most important principles of the proper diet of the child during the given phases of a child development. Moreover, the correct timing of nutrition and drinking regime during the sport are mentioned in this second part. Based on those theoretical foundation is built the practical part. Results obtained from an analysis of the diet of 18 young swimmers and 18 triathletes at the similar age are interpreted in the practical part. A range of the respondents' age was between 10 and 15 years. The results show differences between those two groups in their diet. Both groups have problems to follow the nutritional recommendations. The differences were found in total energy, protein and iron intake. Both groups showed similar characteristics in vitamin C intake.

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

Follprecht, Daniel ; Kovářová, Lenka (advisor) ; Malá, Lucia (referee)
TITLE OF THESIS: Nutrition habits analysis in triathlon in elite youth categories. OBJECTIVES OF THESIS: The aim of this diploma thesis is to create a seven-day model nutrition plan for elite triathletes aged 15 - 18 based on an analysis of their current eating habits and anthropometric indicators together with verification of the effectiveness of nutritional recomendations after six months of compliance. METHODS USED: In our thesis we used qualitative and quantitative methods. Microsoft Excel was used for the graphical representation of anthropometric indicators and for the analysis of the current diet. Furthermore, the Sportvital-Nutrition program helped us in our work, especially in the analysis of meal plans of the monitored group. RESULTS: We found that the percentage of nutrients ingested by the monitored triathletes is on average 49 : 32 : 19 % (carbohydrates : fats : proteins), which does not correspond to the recomendations in the field of nutrition in endurance sports for youth categories. They do not even meet the correct ratio of fatty acids ingested fats according to the recommendations of the World Health Organization. Only three triathletes met the recommendations od PUFA intake, five triathletes met the recommendations for MUFA intake and no triathlete met the lower limit for SFA...
