Figure 3. Mean R-R (panel A), ln rMSSD (panel B), ln SD1 (panel C) and SD2 (panel D) at rest (REST), during exercise (EXE), during post-exercise water immersion (WI), during post-water immersion (POST-WI), and during post-recovery period (POST-REC) for no immersion (CTRL, ο), cold water immersion (CWI, ▪), temperate water immersion (TWI, Δ) and hot water immersion (HWI, ▾).

^a p<0.05 vs REST for all recovery strategies; * p<0.05 vs rest in CTRL; ^δ p<0.05 vs rest in TWI; ^Ω p<0.05 vs rest in HWI; ^# p<0.05 CWI vs CTRL; ^$ p<0.05 HWI vs CTRL. Data are shown as mean and SEM.
