What is the correct definition for recovery heart rate? a. an ideal range to aim for when exercising, calculated using the maximum heart rate formula. b. a measure of heartbeats per minute when the body is completely at rest. c. number of beats per minute the heart drops after exercise. d. number of heartbeats per unit of time, usually expressed as beats per minute.

The answer is Number of beats per minute the heart drops after exercise.    Your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. This “recovery heart rate” is measured as part of an exercise stress test.
