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

Achievement motivation in long distance triathlon
Buchar, Matouš ; Kovářová, Lenka (advisor) ; Horčic, Josef (referee)
Title: Achievement motivation in long distance triathlon. Objectives: Determine the level of achievement motivation among triathletes, what are the differences in achievement motivation in comparison with the general population and what are the main components of achievement motivation among triathletes focusing on long distance triathlons. Methods: To determine achievement motivation we will use LMI questionnaire. To determine the level of achievement motivation we will convert the results of averages using standardized table of standard nine values that will be drawn to test profile. For statistical comparison of triathletes and general population will be used the unpaired t-test and we will determine statistically significant differences. Results: Triathletes shown higher values in the various dimensions of achievement motivation in comparison with the general population. Statistically significant differences were demonstrated in the dimensions of: endurance (t = 2.08; p ≤ 0.05), engagement (t = 2.34; p ≤ 0.05), flow (t = 2.08; p ≤ 0.05), the preference of difficulty (t = 2.14; p ≤ 2.14) and competition (t = 2.37; p ≤ 0.05). Keywords: Triathlon, motivation, achievement motivation

Characterization of a synthetic leoligin derivative, with agonistic FXR and enhancing macrophage cholesterol efflux activity
Kovářová, Lenka ; Kovařík, Miroslav (advisor) ; Doleželová, Eva (referee)
Charles University, Faculty of Pharmacy in Hradec Králové, Department of Biological and Medical Sciences University of Vienna, Faculty of Life Sciences, Department of Pharmacognosy Candidate: Lenka Kovářová Supervisor: Pharmdr. Miroslav Kovařík, Ph.D. Consultant: Dr. Angela Ladurner Title of the diploma thesis: Characterization of a synthetic leoligin derivative, with agonistic FXR and enhancing macrophage cholesterol efflux activity Atherosclerosis is a pathologic multifactorial process triggering the development of cardiovascular diseases, which are the leading causes of death in the western world. The initial phase of atherosclerosis is characterized by the accumulation of lipid particles, mainly low-density lipoproteins (LDL) and macrophage-derived foam cells in large arteries, leading to the gradual thickening of the vessel wall. These progressive alterations elicit plaque formation, followed by rupture, thrombosis and finally can lead to a cardiovascular event. Reverse cholesterol transport is an important preventive mechanism, which ensures removal of excessive atherogenic lipoproteins from macrophages. This efflux is facilitated by ATP binding cassette transporters, mainly ABCA1 and ABCG1 and in part by scavenger receptor B1 (SR-B1). Several nuclear receptors, including PPARγ, LXRα and LXRβ...

Zapala, Michal ; Honsová, Šárka (advisor) ; Kovářová, Lenka (referee)
Title: Somatotype comparison of current UK FTVS students and UK FTVS students forty years ago. Objectives: Main aim of the theses is to compare the current level of student's somatic prerequisites to successful performance studies at UK FTVS in comparison with the somatic level of students studied forty years ago. Another aim of the theses is to illustrate method for measuring body fat by calliper. Subject and Methods: The total set consists of 901 somatotypes of students UK FTVS. Somatotypes were processed from protocols on the results of measurements, which contains the components values of somatotype and somatic parameters necessary for their determination. Processed values of somatotype were compared through statistical processes and through somatocharts. The illustration was created with a pencil simply in a lines with a minimal of shading. Results: Endomorphic components of somatotypes increased in a comparation with a set of students who studied fourty years ago. Higher values could have result in difficulties with fulfilment of practical credit requirements of endurance skills. Conversely mesomorphic components are lower against second set of students. It may result in difficulties with fulfilment of practical credit requirements of power skills. Keywords: somatotype, retrospective study,...
