Columns defined by measurement times, rows defined by selected variables of RPE, HRV and brain activity. Brain activity divided by cerebral lobes and subdivided by frequency bands, mean power spectrum of total spectrum (4-70 Hz), theta (4-8 Hz), alpha (8-13 Hz), beta (13-30 Hz) and gamma (30-70 Hz) frequency. Exhaustion values normalized to first stage of GXT (%50W), Post5-15 values normalized to pre-rest (%Pre). Median (IQR) values,
1 only including 14 subjects and
2 only including 13 subjects according to failed iAPF detection.
