VHP may better index parasympathetic tone than resting HR in healthy adults; leaves open whether training raises VO2max via enhanced vagal control.
Is aerobic power associated with parasympathetic control of resting heart rate in healthy subjects?
Higher aerobic power is closely associated with increased parasympathetic tone, which is the primary mechanism for maintaining lower resting heart rates in fit individuals.
W. L. Kenney (1985) studied this question.
