Effect of artefacts on determination of aerobic threshold
Jaroš, Oliver ; Korvas, Pavel (referee) ; Janoušek, Oto (advisor)
The bachelor's thesis deals with the identification of artifacts occurring during running and swimming and the influence of these artifacts in determining the aerobic threshold from RR intervals using the analysis of detrended fluctuation and its 1 index during a stress test. First, the theoretical part is discussed, where all information related to the definition of training zones, HRV, detrended fluctuation analysis and the method of determining the aerobic threshold from DFA are described. The second part of the work is practical and deals with specific measurements, their processing and subsequent statistical analysis of the results. It was found that for artifacts occurring during running, the mean absolute error in determining the aerobic threshold was only 1.58 beats/min. and after applying the correction method only 0.33 beats/min. When analyzed with artifacts occurring during swimming, this error was up to 9.89 beats/min, and after applying the correction method it was only 0.67 beats/min.
