Heart rate variability high frequency normalized units

1. Aerobic exercise is associated with heart rate variability high frequency normalized units in humans (β = 0.503).

   “heart rate monitor high frequency normalized units (β = 0.503, R2 = .225; F = 3.200, P = .003) after adjustment for basic characteristics.”
