Heart rate variability during night sleep and after awakening in overtrained athletes
Article Abstract:
A study is conducted to test the hypothesis of autonomic imbalance in overtrained athletes during sleep and after awakening with analyses of heart rate variability (HRV) and nocturnal urine stress hormones. The present findings suggest that in overtrained, cardiac autonomic modulation is at the level of control athletes during sleep, but the parasympathetic cardiac modulation is slightly diminished after awakening.
