Correlations
Figure Graphical presentation of the agreement between the measured median values of humidity (Selected data from the Comfort Score were positively correlated with physiological parameters (e.g. heart frequency (HF), lactate) during ergometry (Fig. Heatmap of the correlation between physiological parameters (heart frequency (HF), percent from maximum HF, lactate) and perceived physical exertion (Borg scale) with selected items and the sum of the Comfort Score questionnaire. Data of 40 subjects across all levels of ergometry were considered.
