Jindra, Matouš ; Heller, Jan (advisor) ; Bunc, Václav (referee) ; Louka, Oto (referee)
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 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...

Novák, Jan ; Nováková, Tereza (advisor) ; Heller, Jan (referee)
Title: Power output and selected cardiorespiratory parameters in elite athletes during the third to fourth week after COVID-19 infection Objectives: The aim of this thesis is to compare power output and selected cardiorespiratory parameters in elite athletes before and three to four weeks after COVID- 19 infection. Since the elite athletes undergo these health checks on a yearly basis, it is possible to compare the data before and immediately after the infection without difficulty. Methods: This thesis has a character of a quantitative research based on testing the outcomes with confirming or denying hypotheses. Out of the total of 64 elite athletes with the CPET data after the infection 17 athletes, fulfilling other criteria, were selected. I was provided with the data by Centrum sportovní medicíny z. s.. These values became the foundation for statistical hypotheses testing. Analysis of the data was done by means of a pair t-test in R software. Results: There were no significant differences in the majority of the spirometry parameters. Only the inspiration vital capacity was significantly higher (p = 0,004) after the COVID-19 infection in 14 athletes with 0,21±0,18 l improvement. There were significant differences in five of CPET parameters. Load in RCP was significantly lower (p = 0,011) in 13...

Chaloupková, Eva ; Heller, Jan (advisor) ; Bartůňková, Staša (referee) ; Kálal, Jan (referee)
Title: Basal metabolism and nutritional intervention for people with spinal cord injuries Objectives: The main objective of this work was empirical research of case evaluation studies (n = 3), where we analyzed: the relationship between energy expenditure (basal metabolism) and energy intake for people diagnosed with spinal cord injury (SCI). The secondary objective was to determine whether the changes in macronutrient distribution and daily energy intake would result in a decrease in body weight and body fat for individual probands. The pilot study in our work was focused on the overview of variable basal metabolism (BM) values for people with SCI. Methods: In our work, we used the method of indirect calorimetry to measure BM and together with the value of working metabolism we determined in the nutritional intervention (n. i.) the ideal energy intake for our probands. We observed primarily measurable changes in the amount of fat and muscle tissue. Results: We have found that, in keeping with the prescribed n. i. rules, all probands achieved to reduce their body weight. The average body weight loss for probands was 0.29 ± 0.02 kg per week. BM values in our pilot study were 15 to 61% lower for our probands (n = 15) and did not correlate with the height of SCI. Key words: spinal cord injury (SCI),...

Title: The analysis of competitors' physical preparation OCR (Obstacle Course Racing). Objectives: The aim of this thesis was to provide the analysis of physical preparation used by the competitors of the obstacle course races. The analysis was completed for all major competitor ability-based classes and then compared among the categories. Methods: For data collection quantitative research was used, provided by the survey method. Its form was an online questionnaire. Results: The research has shown that the competitors of the enthusiast class - recreational athletes mostly value the experience and the adrenalin the obstacle course races bring them, overcoming own maximum, looking for new challenges etc. Those are the type of athletes who do not have high performance expectations, they are not oriented to perform at their highest of abilities. Although, they are still capable of winning. They win over themselves, happy when they manage to overcome own fears. They consider as winning not only expanding own physical and mental capacities, but also just the actual finishing of the race. Performance athletes, compared to the recreational ones, are able to plan their training sessions much more effectively and with better training goals. The performance oriented athletes are much more performance...

Thesis title: Kinesiophobia in patients on renal dialysis therapy - questionnaire study. The aims of the thesis: To characterise the term kinesiophobia and to evaluate the dependence of the measure of fear of movement on sociodemographic and clinical variables with the use of the Tampa Scale for Kinesiophobia questionnaire (TSK-CZ) in a group of respondents on renal dialysis therapy and a group of healthy respondents. Methods: To determine the dependence of the measure of kinesiophobia on selected variables, the TSK-CZ questionnaire was used in Fresenius Medical Care dialysis centres across towns in the Czech Republic. The reference group of individuals with no renal disease - healthy respondents - was addressed by means of the Survio.cz website. The research comprised a group of respondents on renal dialysis therapy (n = 135) and a group of healthy respondents (n = 135). The collected data was processed using statistical methods - descriptive statistics and data analysis (t-test, Chi-squared test, ANOVA, Spearman's correlation coefficient). After that, the data was transferred to tables and charts and was evaluated. Results: On the basis of the TSK-CZ questionnaire, a significant difference in the measure of fear of movement was found between the respondents on renal dialysis and the healthy ones...
