BACKGROUND: Research has established the positive link between physical activity and its impact on health among adults. Generally, as people get older, they are less likely to be active. Black women comprise 13% of the women in the US but constitute 52% of women who are inactive. Existing articles on exercise motivation among Black women have generally assessed sedentary individuals. Little research has examined the motivations to exercise among physically active Black women. METHODS: Guided by the regulators of the Self Determination Theory, the 56 item Motivations of Marathoners Scales for Triathletes (MOMS-T) was used to assess the motives of (N =121) midlife to older Black women (36+) and then transformed into a semi structured guide to interview (n =12) women to further understand their motives for participating in triathlons. RESULTS: Univariate and two way analysis reveals age as a predictor for the four regulators (external, introjection, integration and intrinsic) but BMI and distance are not. Integration demonstrated the highest mean. Qualitative results indicated that construct of self competition and receiving medals are important aspects of participation but are not measured in the survey. A new scale, triathlete lifestyle, should be considered within the MOMS-T. CONCLUSION: Findings were representative of the study population and comparable to previous studies. The survey transformation of the MOMS-T into an interview guide provided additional qualitative explanations of the survey answers demonstrating a secondary method of gathering data as important to provide further understanding about constructs not measured in the survey form of the MOMS-T.

Title: Evaluation of force presumptions for swimming triathletes from Czech team in training cycle 2010-2011 Intention of work: Evaluation of specific force presumptions for swimming and ability maximal utilit force efficiency in long time stress, wide spektrum of triatlonist from beginners to elite czech competitors. For evaluation we used 3 indikators: 1. average Power Output - PO - [W] 2. average power output on kg body weight - PO.kg-1 - [W.kg-1 ] 3. complete work - W - [Nm] Method: Testing on swim trainer Biokinetic by tests which simulated free style strokes and butterfly strokes. 10 strokes by free style and butterfly styl, 50 and 100 strokes by butterfly style. Results: Some people lives in mistake about their directionality. Someone think, that he is better for long distance, and oposit eis true. Lot of people, in our test, made more work [Nm] in free style strokes, than butterfly strokes. More offen people made more work [Nm] in butterfly strokes. Our people swim butterfly just especialy and that's the reason, why they have more force in crowl. Keywords: Biokinetic, triathlon, swimming, testing, swim force.

NAME OF THE AUTHOR: Bc. Eva Babicová SUPERVISIOR: Mgr. Lenka Kovářová, Ph.D., MBA Title: Possibilities of using the Myotest for the evaluation of the running technique Objectives: The aim of this work is to do pilot study of Myotest device and on the basis of the results obtained and analyzed materials is used to determine the possibility of the practical uses of the Myotest for evaluating the running technique. Methods: This thesis is its character a pilot study. We used literature search literature dedicated to technique of run and device Myotest. These information were used to determine the parameters of technique, which can used to evaluate running technique. Subsequently, field measurements were performed, which confirmed and verified data obtained from the research literature. Results: The results were processed using MS Excel. Using an analysis of the measured results have determined the possibility of practical use of the device. With Myotest PRO instrument, it is possible to analyze the parameters of the running technique, such as speed, stride length and frequency, the vertical movement of the center of gravity, takeoff angle and impact, and reactivity or regularity of stride. Device results are evaluated using average values of the test section. On the basis of the analyzed parameters...

Triathlon is still a popular sport that is gaining more and morepopular. We distinguish two basic directions. Short, or if the Olympictriathlon and long, or if Ironman. In my work I examine the long triathlon. Its history, training cycle and its specifics. I myself an active rider, so this issue is very close to me. I work divided into a theoretical part, where I deal with theories and general laws of triathlon. Such as history, specifics of Ironman training and unit training cycle disciplines of triathlon course and other sub-themes, which veryclosely related to the topic. In the empirical part, I chose the method ofexperiment and research he firsthand, I attended a long distance triathlon race in the annualtraining cycle. Acquired knowledge, I capitalized on in the race and described in this thesis. This work may serve as a kind of guidance and example, and the direction of training, which can be applied when attempting to handle the challenge on behalf ofIronman. I deal with are also problems of nutrition during the race, which is out of a totaltrénovanosti organism one of the most important factors affecting performance. The workcontains several training and racing tips that I gained studying foreign literature and own racing experience.

Title: Body composition and dietary habits of triathletes Objectives: Assessment of differences in selected parameters of body composition between racing and non-racing season of triathletes and exploration of their dietary habits Methods: The bioelectric impedance Bodystat Quadscan 4000 was used for getting input and output data of body composition. Chosen anthropometric parameters were measured. Questionnaires generated by software SURVEY and FITLINIE were used to explore dietary habits. Results: Results of our study shows that different physical load in non racing and racing season in triathlon influences some parameters of body composition, but everything is influenced by individual variability. Dietary habits are influenced by individual variability too. Keywords: body composition, triathlon, bioelectrical impedance, nutrition in sport

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
