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.
