How do time and frequency domain measures of heart rate and blood pressure variability reflect sympathovagal balance in endurance athletes?
Time and frequency domain measures of heart rate variability, specifically SD of RRI, RRI RMSSD, HF, and total power, are effective non-invasive methods for evaluating parasympathetically modulated sympathovagal balance in athletes.
Uusitalo et al. (1996) studied this question.
