Comparison of physiological parameter data generated by the Metalyzer 3B in the laboratory and the Metamax 3B for use in field research
Kříž, Tomáš ; Nohel, Michal (referee) ; Chlíbková, Daniela (advisor)
Increasing quality of the sport performance creates demands related to sports data acquisition which occurs in the natural environment. Such demands are then placed on the equipment manufacturers which need to adapt and adjust equipment for artificial as well as the outdoor environment. Furthermore, required equipment must be substantially reduced in terms of its weight as well as the size to minimize possible interference with the outdoor conditions. The remaining question is to which extent such adjustments influence the validity of the data inquiry and whether laboratory testing should be prioritized before outdoor testing. This thesis aims to provide a comparison between two oxygen consumption analysers across the unified evidence-based testing protocol. The first half of the testing is made with Metalyzer 3B (laboratory-based equipment), and the second part of the testing is made with Metamax 3B (outdoor-oriented equipment). Both analysers are produced by the Cortex company. The theoretical part of this project introduces the underlying theory of the oxygen consumption analysers and presents various methods used for the establishment of the VO2max. The practical part includes the measurements of set parameters on both devices with an identical test protocol. The t-test was used to prove statistical significance between Metamax 3B and Metalyzer 3B. Results of statistical analysis (V'O2 p = 0,54; V'CO2 p = 0,087; SF p = 0,49; V'E p = 0,2; DF p = 0,28; time p = 0,59) within the range of 95% confidence intervals.

Change in breathing economics during exercise due to previous application of breathing exercises based on the Wim Hof method to warm up
MARKO, David
The Wim Hof method is a worldwide phenomenon nowadays. The aim of our work is to determine whether the application of breathing exercises based on WHM will affect the breathing economy in subsequent spiroergometry in adolescent runners (14 boys and 14 girls). Runners underwent two identical graded exercise tests within 3 days, while before one of the tests was performed breathing exercise containing three rounds of controlled hyperventilation and subsequent breath holds. The spiroergometric test consisted of 4 two-minute load phases 1, 2, 3, and 4 W-kg-1. After the application of breathing exercises, there was a significant effect on the kinetics of VO2 (5.09%, 3.11%, 1.55% and 3.39% increase in individual phases of the test). There was also a significant increase of VO2-HR-1 (7.89%, 5.02%, 6.78% and 6.9%). On the other hand, smaller values were measured for the RER, where significance was demonstrated in the first three phases (7.53%, 2.94%, 2.7% and 0.85%). The parameters VE, VT and BF were not significantly affected. No significant differences were measured in the change in the involvement of the breathing sectors. The results of our work show that due to breathing exercises, including controlled hyperventilation and breath holding, the kinetics of oxygen consumption can be accelerated, which can lead to facilitated endurance performance.

The impact of intervention breathing programme on breathing economy during increasing load
POUL, Daniel
Breathing is essential part of our life. Breathing exercise can help acquirement of proper breathing. Thanks to this process, sports performance can be improved. The aim of our work is to determine differences in values and compare results of spiroergometric parameters from testing on a bicycle ergometer in the laboratory of functional load diagnostics. We obtained the results by an entrance test and a final test tested after eight weeks. Between testing, selected individuals performed a respiratory intervention program. Nine performance university athletes, especially focused on football, got involved in our research. Data at the rest position and load were crucial. We focused on dynamic ventilation parameters such as tidal volume, respiratory rate, minute ventilation or oxygen consumption. In the output test, we also recorded changes in values in the respiratory segments, abdominal, thoracic and subclavian areas. We verified the results from the point of view of material and statistical significances. Both of these significances were evaluated in this thesis. The materially and statistically significant differences in the results of measurement were improved in the oxygen consumption by our probands. The studied probands were able to improve in various phases of load, for example, the material significance was detected at the respiratory rate during the load of three watts per kilogram. Ascertained results were not improved in all monitored parameters. The most significant changes were discovered in the three-watt load during the respiratory rate from 32,8 +- 7,2 to 30,9 +- 5,1 breaths per minute. Probands reduced oxygen consumption by 14.8 percent.

Muniová, Zuzana ; Jebavý, Radim (advisor) ; Blažek, Dušan (referee)
Title: Energy expenditure of exercise on stable and unstable surfaces Objectives: The aim of this study was to investigate the difference between energy expenditure of exercise on stable and unstable surfaces. Methods: Ten athletes (aged 27.4 ± 2.67), current students or graduates from Faculty of physical education and sport at Charles University, took part in this study. The study was an intragroup randomized experiment. Energy expenditure was determined by spiroergometry based on inhaled O2 and exhaled CO2. The metabolic analyzer MetaMax 3B was used to determine respiratory parameters. The measured data were analyzed through basic statistical operations. Results: The highest average energy expenditure of 252,6 kJ was measured for dynamic exercises on unstable surfaces. The value for the average energy expenditure on stable surfaces was 225,7 kJ. This was followed by energy expenditure of static exercise on unstable surfaces, where the average value was 205,4 kJ. Probands showed the lowest energy expenditure during static exercise on stable surfaces, where the average value was 177,5 kJ. The average difference between static exercise on unstable surfaces and static exercise on stable surfaces was 15,9 %. The difference between dynamic exercise on unstable surfaces and dynamic exercise on stable...
