Three Surprising Uses for Heart Rate Variability
Many racehorses are high-earning elite athletes. Like human pro athletes, they have an entourage of trainers, coaches, and therapists. Unlike human athletes, they can't tell their coach when they feel pain or fatigue. Horse trainers rely on body language and any objective information they can get.
Over the years, some use baseline heart rate variability (HRV) measurements to track the horse's recovery time and scheduled rest or active recovery days accordingly. Scientific research indicates that horses' HRV readings vary day to day in response to illness, workouts, and emotional stress.
