Analysis of three several-month training sessions of the endurance runner at higher altitudes
VONDRÁŠKOVÁ, Aneta
The aim of this diploma thesis is to analyze three several-month concentration of a long-distance runner at higher altitude. Specifically, we compared the results of the measured values before staying in zones of high altitude and after arrival from high altitude. The tested individual was housed in Kenya in the town of Iten, located at 2,400 meters above sea level. To elaborate this thesis, we used the method of content analysis and the comparative method. To obtain the results, we used laboratory tests spiroergometry, spirometry, body composition and Wingate test. Then, the data was processed using material significance. The material significance was defined using Cohen's d. Our results showed an increase in red blood cells, an increase in VO2max, a reduction in heart rate, a reduction in morning heart rate. From these results, it is clear that alpine training has a positive effect on the performance of the athlete.

Analysis of the influence of ski training in the first year of the study program PE and Sport at high altitude on the selected students' fitness requirements
KŘÍŽENECKÝ, Daniel
This thesis analyzes the physical predispositions of students from the first grade of the physical education who attended a ski course. This course took place in France. This fact is quite important for the thesis because the course took place in a higher altitude. The main aim of the thesis is to compare results of tested probands before and after the course. At first, there was an information meeting where we provided more information about the aim of this thesis and about the testing. After this meeting we went to KTVS laboratory where the first measuring happened. After that all probands and other students left for the ski course to France for a week. The accommodation was in an Alpe d´Huez center which is situated 1860 meters and the highest point of it which is 3330 meters above the sea level. Probands were practicing in very high altitude all week. In this thesis we also look at how hard it is to work in this altitude, what kind of advantages and disadvantages it might have and which danger might come up. It is also necessary to think about the process of how probands should prepare themselves not to underestimate anything. The second measuring happened after the return to the Czech Republic. It also took place in KTVS laboratory. After the measuring we started analyzing all measured data of probands. We compared this data. After that we realised what this course brought to the students. We wanted to know what happens in following parts: body composition, Wingate test, spiroergometry and spirometry. In each part we were interested in some specific parameters that are related to this topic. We included specific parameters like: body fat, muscle mass, body water, maximum performance, average performance, maximum 5 seconds performance, fatigue index, VO2max, oxygen pulse, minute respiratory volume and vigorous vital capacity.

Sukovič, Richard ; Jindra, Matouš (advisor) ; Brtník, Tomáš (referee)
EFFECT OF DIFFERENT SIZES OF WHEELS OF IN-LINE SKATES ON ENERGY EXPENDITURE Objectives: The aim of this bachelor thesis is to determine the difference in energy expenditure when using different sizes of wheels of in-line skates. Methods: The research group consisted of 5 people in age 26,4 ± 2,2 years. This was an experiment. The calculation of energy expediture was based on the amount of oxygen consumption (VO2) and exhaled carbon dioxide (VCO2), i.e. indirect calorimetry. For the analysis of respiratory gases MetaMax 3B measuring device was used. Three sizes of wheels of the same hardness were tested. The rides were carried out on a 1,5 km section of a cycle path with the effect of the height difference of 2 mm/m. Probands completed one test ride (with a cadence of 70 rpm) on each size set of wheels. Test ride lasted for 5 minutes. For results were processed values of 3 minutes steady state VO2. Results: We found out a noticeable difference in energy output between 72 mm and 90 mm large wheels. The difference between driving on 72 mm and 80 mm large wheels and driving on 80 mm and 90 mm large wheels was, due to the standard error of measurement, insignificatnt. Conclusion: The energy expenditure reached a noticeable increase in driving with a larger diameter of wheels compared to driving on...

Kopecká, Anežka ; Radvanský, Jiří (advisor) ; Tetřevová, Lenka (referee)
The aim of the study was to compose and realize physiotherapeutic program for children with congenital heart disease to improve their postural-respirational function and to assess the influence of this program on cardiopulmonary functions of the patients. Our group had five patients with mean age of 15,6 years. Each of them underwent initial examination of the motor system, spirometry and spiroergometric exercise test. Physiotherapeutic program consisted of 8 individual therapies and home-based exercise. Therapy was composed from manual techniques, exercise according to Dynamic neuromuscular stabilisation concept and exercise with inspiratory trainer and improvised PEP system. The final examination was performed in the same manner as the initial one. We compared the results of both examinations, but we found no significant improvement after the physiotherapeutic program.

VONDRUŠKOVÁ, Jana
In this Bachelor Thesis, the author is focused on the observation of top athletes in 800 m, 1,500 m and 3,000 m runs. The thesis was based on the comparison of racing performance with the results of laboratory tests. The purpose of the work was to predict the performance in certain disciplines based on predetermined tests. We used the content analysis, content synthesis, and measurement method to select the data. We used the measurement method to determine the results from the laboratory. The laboratory tests we used were spiroergometry, spirometry, body composition test, and Wingate test. Then we processed the data using material significance. For significance, we used the Sperman's correlation coefficient. We have defined materiality by Cohen´s d. In the end of the work, we determined the connection between the performance of athletes in 800 and their results from Wingate test, as well as some connection of performances at athletes in 1 500 m, 3 000 m and their results from the spiroergometry test.
