Heart rate recovery (HRR) is defined as the rate at which heart rate declines after exercise.

• A. The rate at which heart rate declines after exercise
• B. The peak heart rate during exercise
• C. The resting heart rate
• D. The rate at which heart rate rises after exercise

Answer: (A)

Heart rate recovery describes how quickly the heart rate drops once you finish exercising. After you stop, the body shifts from sympathetic to parasympathetic dominance, so the heart rate rapidly declines toward resting levels. The faster this decline, the better the autonomic balance and cardiovascular fitness are considered. By definition, HRR is about that post-exercise decline, often measured as how many beats per minute the heart rate falls within a short recovery period after peak exercise.

The peak heart rate during exercise is simply the highest rate reached during effort, not how quickly it returns to baseline. Resting heart rate is the rate when you’re at rest, not after exercise. The rate at which heart rate rises after exercise describes the increase during the workout or the initial recovery not the decline after stopping.
