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...

Coufalová, Klára ; Heller, Jan (advisor) ; Harsa, Pavel (referee) ; Vomela, Jindřich (referee)
Title: Physical profile of judo athletes and its changes due to body weight reduction Aim of work: The aim of this study was to determine the effect of intensive pre-competitive body weight reduction on body composition, anthropometric parameters, postural stability, reaction time, maximal isometric muscle strength and biochemical parameters in the blood of elite judo athletes. Methods: The work compares the results of laboratory testing at the beginning and at the end of body weight reduction. Nine male judo athletes (age 22.3 ± 2.4 years) from the Czech national team participated in the research. For laboratory testing we used bioelectrical impedance analyser InBody 720, anthropometric equipment, pressure plate FootScan, dynamometer and apparatus for measuring reaction times of Biomedical laboratory UK FTVS and equipment for the collection of capillary and venous blood. We created a survey to gather more information about pre-competitive weight loss, attended by 53 competitors (37 men and 16 women, mean age 23.7 ± 3.2 years) who practise judo, wrestling Greco-Roman and freestyle, boxing, kickboxing, thaibox, taekwondo or karate. Results: We found a statistically significant (p<0.01) reduction of body weight, average weight loss was 4.6 % (on average 3.4 ± 1.6 kg). This reduction was reflected in...

Novák, Jaroslav ; Zeman, Václav (advisor) ; Votík, Jaromír (referee) ; Heller, Jan (referee)
Cardiorespiratory kapacity in sporting population J. Novák Summary VO2max and VO2max/kg values were directly obtained during 2777 measurements in competitive athletes and active but not competing subjects. The normatives of cardiorespiratory capacity for different age groups of male and female endurance athletes (Group A), team sport players (Group B) and other sports (group C) were established, and compared to normatives for Czech population based on the International Biological Program (IBP) results (Seliger a Bartůněk 1976). The most favorable values of cardiorespiratory capacity (both VO2max; VO2max/kg and W170;W170/kg) were found in the group A athletes (endurance trained) - both males and females. Their level highly exceeded the values of untrained CS IBP population and also those obtained in control group D in this study. The highest correlation was found between VO2max and Wmax and between VO2max/kg and Wmax/kg. This high correlation was very similarly high in the whole sample of 2777 examinations, in the sample of men (n=2015) and women (n=762) and also in all age-groups in different athletic groups A to D. It was proved that VO2max and VO2max/kg values could be calculated according to the maximal performance attained on bicycle ergometer. During spiroergometric examination the values of stroke...

Title: The energy cost of ski mountaineering. Aim: The aim of study was determine effect of speed and slope on energy expenditure during ski mountaineering. Methods: Twelve athletes (mean age 30 ± 8 years,) took part in the study. This was random intragroup experiment. The energy expenditure was determined by spiroergometry based on the ratio of O2 and CO2 exhaled. The anthropometric values and individual ventilation parameters was measured and followed individual warming up. The study was undertaken on the treadmill (Saturn HP Cosmos, Germany) allow to walking with specially adapted roller skis and poles modified for ski mountaineering. The test was initiated by a warm-up lasting for 4 minutes at speed at 3.5 km·h-1 and 16% slope. The next measurements consisted of 4 parts: walking at 24% gradient and speed 3.5 km·h-1 , 20% gradient and speed 4.2 km·h-1 , 16% gradient and speed 5.1 km·h-1 and 12% slope with a speed 6.8 km·h-1 . The load lasted for 8 minutes 30 seconds in order to achieve the elevation 200 m. The passive recovery for 20-25 minutes was administered between each measurement. Results: When the body was after the warm-up on load, the average energy expenditure nonlinearly increased with decreasing slope and increasing speed. The average energy expenditure at 24% slope and speed 3.5...

Transfigurations of the image of the Other in Czech travelogues of the long 19th century
Heller, Jan ; Putna, Martin (advisor) ; Havelka, Miloš (referee) ; Šima, Karel (referee)
Transfigurations of the image of the Other in Czech travelogues of the long 19th Century Abstract of the dissertation thesis Mgr. et Mgr. Jan Heller The thesis focuses on constructions of the image of the Other in Czech travelogues of the 19th century. The travelogue is a peripheral literary genre, both an artistic text and a historical source, and thus enables the viewer to combine perspectives of literary criticism and historical anthropology. Special attention is paid to religious motifs owing mainly to the fact that this theme has been left out of focus in the present research thanks to the emphasis on the linguistic and historic character of the Czech national emancipation movement. The intention of the thesis is to describe literary techniques in the individual travelogues (direct representations, narrative strategies, topics, attributes of characters) and the function they serve in the building of the image of the Other and thus of the image of oneself at the same time. The goal ...

Brychta, Petr ; Heller, Jan (advisor) ; Havel, Zdeněk (referee) ; Harsa, Pavel (referee)
Title: The influence of age, gender and movement activity on the reaction abilities of lower limbs. Objectives: The main objective of this dissertation was to find the reaction abilities of pubescent's (aged 10 - 15years) lower limbs on the basis of age, gender and movement activity. The further aim was to determine the pubescence period (age) when the most noticeable decrease of the visual disjunctive motor response time of lower limbs occurs. Methods: 214 boys and girls aged 10-15 years (157.8 ± 10.8 cm; 47.2 ± 10.7 kg) participated in this research. Simple, choice and disjunctive reaction time of lower limbs was measured through the Fitro Agility Check test. The results processing, including statistical procedures, was carried out using the Matlab (MathWorks, Inc.) programming environment, an IBM SPSS Statistics 22. Three-way ANOVA and Tukey post-hoc tests (α=0.05) were used to determine the individual parameters connection. Results: With increasing age, year over year, we found important differences and reaction time decreases of all types of reaction speeds. Testing brings to light the fact that the most noticeable decrease of both selection and disjunctive reaction time of lower limbs are between groups of 11 year olds (11.00-11.99) and 12 year olds (12.00-12.99). The most noticeable decrease...
