Notes: *P < 0.05, **P < 0.01. ΔHR is calculated by subtracting HR during baseline measures from HR during recovery period (see values in Table 1). HR increases due to a stress response; therefore, positive values of ΔHR indicate poorer recovery of HR (less approach towards baseline). ΔSDNN is calculated by subtracting SDNN during baseline measures from SDNN during recovery period. SDNN decreases due to a stress response; therefore, positive values of ΔSDNN indicate more efficient recovery of SDNN (more approach towards baseline).
