Values are means ± SE. HRV, heart rate variability; RMS, root mean square residuals of linearly detrended RR intervals; rMSSD, root mean square of successive differences of RR intervals; sqrtLF, square root of low-frequency power (LF); sqrtHF, square root of high-frequency power (HF); sqrtTOTAL, square root of total power (TOTAL).
