Krenarová, Kateřina ; Heller, Jan (advisor) ; Novotná, Viléma (referee)
Title: Influence of sports load on the physical condition of trampoline gymnasts Objectives: The aim of this thesis is to assess the relationship between the sport load and functional and physical parameters of trampoline gymnasts. Methods: The thesis has the character of empirical research carried out in the form of observation. The research group consisted of 29 active trampoline gymnasts aged 9 to 17 (20 girls and 9 boys) participating in trampoline jumping competitions at national or international level. The body composition was analysed by Bioelectrical Impedance Analysis (BIA, Tanita MC - 980), functional parameters were tested via Bosco Vertical Jump test (BT) and kinesiological analysis of the athlete. Anamnestic data were collected as a part of kinesiological examination of the gymnasts. Results: Parameters of trampoline gymnasts were compared from the age point of view - probands were divided into age categories ZAC (10.7 ± 1.1 years) and JUN (14.9 ± 1.2 years) and from the gender point of view - parameters of girls and boys. The values of somatic parameters in JUN were higher than in ZAC; girls had a significantly higher proportion of body fat (d = 2.307) and a significantly lower proportion of Total Body Water (d = 2.222) than boys. JUN did significantly more work during BT (d = 2.059),...

Title Exercise programmes for individuals with ESRD treated with dialysis and their effect for quality of life. Objective: To evaluate an effect of regular 6 months intradialytic exercise programmes at functional state and quality of life in patients with ESRD. Methods: 15 patients with ESRD on haemodialysis participated in exercise programme during haemodialysis. Senior Fitness Test (SFT), dynamometry of hands and questionnaire tool SF-36 were used to evaluate physical function and quality of life of the research group before and after 6 month exercise period. Results: Results of output motoric tests and questionnaire tool after exercise intervention were conform with majority of cases or better than the results of input tests. Improvement was recorded for patients, that did exercises regularly. Only in one test we observed statisticaly significant change- in case of women, increased their test performance in 2-minute step test (p<0,04). In case of men there were no statistical significant difference. Statisticaly significance of changes between input and output tests, were evaluated by small number of patients in group. In majority of the results before and after exercise intervention were no statistical significant difference. Summary: Regular exercise programmes realized during hemodialysis can...

Formánková, Dita ; Vomáčko, Ladislav (advisor) ; Heller, Jan (referee)
Title: Comparison of universal and specific functional stress tests of ski-mountaineerers. Objectives: The aim of the thesis is to compare maximal functional parameters of ski-mountaineerers measured during three functional laboratory stress tests. The functional stress tests were set on a treadmill, bicycle ergometer, and on a ski-mountaineer trainer. Consecutively, there is evaluated the meaning of testing of the functional parameters on the ski-mountaineer trainer. Methods: Interindividual and intraindividual descriptive study of 10 ski-mountaineerers of middle and high level performance. Results: The respondents reached the average value of VO2max 63,3 ml.kg-1 .min-1 on the ski-mountaineer trainer, 67,5 ml.kg-1 .min-1 on a treadmill and 66,5 ml.kg-1 .min-1 on a bicycle ergometer. The average measured HR on the ski-mountaineer trainer was 179 heartbeats/min, on the treadmill 185 heartbeats/min and on the bycicle ergometer 183 heartbeats/min. The average value of R reached the value of 1,09 on the ski-mountaineer trainer, 1,18 on the treadmill and 1, 19 on the bycicle ergometer. The highest measured value of VO2max reached on the treadmill was 79,3 ml.kg-1 .min-1 , the bycicle ergometer enabled to reach maximum 76,5 ml.kg-1 .min-1 and the highest value reached on the ski-mountaineer trainer was...

Comparison of proportional biological age and theoretical skeletal age on the example of swimmers
Peřinka, Filip ; Musálek, Martin (advisor) ; Heller, Jan (referee)
and key words Problem definition: Assessment of the biological age is possible to obtain by several methods, both simple and more sophisticated. Results will surely not always comport. Currently radiography of distal epiphysis antebrachia and ossa manus (ossa carpi , ossa metacarpi, phalanges) is considered to be the most exact method, however for the reason of unavailability of X-ray pictures, we require for assessment of the bone age, this method is used exceptionally mainly for its invasiveness. Theoretical estimation of the bone age might be a kind of alternative method when assessed from derived coefficients of regression equations, made on a base of conventional radiographic method. In the contrast of that, age rating by biological proportionality is considered a substitution of the bone age criteria. So, the problem is the mutual diversity and difference of the two methods which are relatively most exact. The Aim: In the thesis, we deal with comparison of the biological proportional age and theoretical bone age within swimming youth, in age range 11-15 years altogether. The main goal is to learn the difference of the biological maturity by using two methods determining the biological age coming out from anthropological measurement of individuals. Methods of resolution: Assessment of the...

Buriánek, Adam ; Heller, Jan (advisor) ; Harsa, Pavel (referee)
Title: Monitoring of reaction abilities in different age categories of judo athletes Objectives: The aim of the thesis was to assess the influence of judo on the reaction abilities among different age groups of judo athletes. This finding should help to develop a view of necessity of focusing on reaction abilities during exercise unit. Methods: During the research a reactometer was used to capture simple and complex reaction time to visual stimulus and tactile response. Overall 166 individuals (100 men, 66 women) took part of the monitoring from which 3 were excluded. Every proband has undergone one test measurement (5 stimuls at least) and two evaluated ones (20 seconds each). The shorter - reaction time score was consider as a result for the particular test. The outcomes were utilized via Kruskal - Wallis test, Pearsons's and Spearman's correlation coefficient, Mann - Whitney's test and others. Results: The biggest difference between reaction period was observed between the age group of 8-10 and older groups. This category has also significantly differed in reaction period and the highest median. Statistically any notable difference was not confirmed among judo athletes and our control group in contrary with the situation between individual age categories. The hypothesis of judo athletes training...
