From: Relationship between post-exercise heart rate variability and skinfold thickness

  VO2max BMI SF
HRR1 (beats.min-1) −0.02 −0.02 −0.16
HRR2 (beats.min-1) 0.15 −0.15 −0.35*

  1. VO2max = maximal oxygen consumption; BMI = body mass index; SF = sum of skinfold thickness; HRR1 = heart rate recovery 1-minute post-exercise; HRR2 = heart rate recovery 2-minutes post-exercise; HFP-E = high-frequency power (HF) heart rate variability (HRV) 25 to 30 minutes post-exercise minus HF HRV 0 to 5 minutes post-exercise (i.e., HFpost2 – HFpost 1); LF:HFP-E = HF to low frequency power (LF) HRV ratio 25 to 30 minutes post-exercise minus HF to LF ratio 0 to 5 minutes post-exercise. *Significantly related, p < 0.05.
