HFpre = High frequency (HF) HRV before exercise, HFpost1 = HF HRV 0 to 5 minutes post-exercise, HFpost2 = HF HRV 25 to 30 minutes post-exercise, LF:HFpre = Low frequency to HF power HRV before exercise, LF:HFpost1 = LF:HF HRV 0 to 5 minutes post-exercise, LF:HFpost2 = LF:HF HRV 25 to 30 minutes post-exercise. *Significantly different compared to the post1 and post2 values. †Significantly different compared to Group 1 (p < 0.05). ‡Significantly different compared to post1 values (p < 0.05).
