Document Summary
Horses and humans have a similar maximum heart rate, but a horse"s is 6x its resting rate, whereas a human"s is 3x its resting rate. A human"s heart becomes more efficient with training. In humans, increased stroke volume and increased heart rate result in increased cardiac effectiveness. In humans, training leads to increased stroke volume. The best way to assess a horse"s resting heart rate is to outfit the horse with a heart rate monitor and capture a reading remotely, while the horse is in its normal environment. The velocity at which heart rate plateaus is a meaningful number. Heart rate is not a great way to measure fitness. However, one can use the velocity at which maximum heart rate is attained to measure fitness. Cardiovascular drift is related to thermoregulation and prevents fatigue from heat buildup. Phases of heart rate recovery: rapid, gradual.
