Štěrba, Jan ; Bílý, Milan (advisor) ; Doktor, Martin (referee)
- 6 - Abstract Title: Comparison of performance tests results determined during kayak spiroergometry with achieved kayak paddling performance. Objectives: The aim of the study was to determine relationships between functional parameters values found during kayak spiroergometry and sport performance at 1000 meters distance, and how are these relationships going to change based on training period. Methods: To determine statistical dependence between sport performance at 1000 meters distance and choosen factors of sport performance, the correlation research was used - as a variable-dependent value the final result of sport performance at 1000 meters distance was used, as a variable-independent amounts functional parameters values found during kayak spiroergometry were used. To discover the statistical dependence methods of Pearson's correlation coefficient and regression analysis were used. Results: General level of kayak-athletes from testing file indicated by functional parameters values and demonstrated by kayak spiroergometry performance depends on kayak- athlete's level of sport performance at 1000 meters distance in prepared-training period only, when importance for general condition is emphasized. We did not discover the same phenomenon based on pre-racing period testing results. Sport performance at...

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...

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...

VLIV VZTAHU DÉLKY DOLNÍ KONČETINY A VELIKOSTI RÁFKU NA PSYCHOFZIOLOGICKOU ODEZVU ORGANISMU Cíle: Cílem této práce je posoudit vliv délky dolní končetiny (DK) na psychofyziologickou odezvu organismu při jízdě na horském kole s odlišnými velikostmi ráfků. Metody: Soubor probandů tvořilo 20 mužů ve věku 26,4 ± 4,2 let. Jednalo se o experiment. Psychofyziologická odezva byla stanovena na základě výkonu (zajetého času), tepové frekvence a subjektivním hodnocení jízdních vlastností horského kola a vlastního vynaloženého úsilí hodnoceného na Borgově škále. Ke kontrolní analýze při testování byl použit přístroj MetaMax 3B. Testovány byly tři velikosti ráfků o stejné šíři plášťů. Jízdy byly realizovány na 800 m dlouhém okruhu. Testované osoby absolvovali každou jízdu s individuálně zvoleným fixním převodem v poloze v sedle s maximálním možným úsilím. Výsledky: Při jízdě na různě velkých ráfcích jsme u skupiny č. 2 (85 -90 cm DK) shledali velký rozdíl (P = 0,016) v dosažených časech při jízdě na různě velkých ráfcích. U skupiny č. 1 jsme shledali významné rozdíly v průměrné tepové frekvenci (P = 0,010), který činil 3 tepy a u subjektivního hodnocení vlastního vynaloženého úsilí pomocí Borgovy škály jsme se pohybovali na hranici významnosti (P = 0,060). Skupina č. 3 (97 - 101 cm DK) se pohybovala na hranici...

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.

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.
