Does resting heart rate variability correlate with hydration status and aerobic capacity in military recruit-age men and women?
Resting heart rate variability metrics correlate with aerobic capacity and hydration status, suggesting potential utility for field-based assessment of combat readiness and physical exhaustion.
Fogt et al. (2009) studied this question.
