RPE, rate of perceived exertion; MeanRR, average R-R interval duration in a measurement, SDNN, standard deviation of all NN intervals; RMSSD, root mean square of successive; RR, intervals differences; TINN, baseline width of the RR intervals histogram; TP, total spectrum power; VLF, very low frequency power; LF, low frequency power, HF, high frequency power, DLpreHRV, daily load i.e., mechanical work of the Pulka expressed in Kilojoules during the day before the HRV measurement.
