B. A higher intensity physical activity will allow for a faster return to your recovery heart rate.
C. A lower-intensity physical activity will allow for a slower return to your recovery heart rate.
D. Intensity level has no effect on the rate of return to your recovery heart rate.

A. A lower-intensity physical activity will allow for a faster return to your recovery heart rate.

Explanation:

Physical activity is associated with an increase in heart rate and myocardial contractility, since the heart helps to supply the muscles with extra oxygen during exercise. Thus, the rate of cardiodeceleration and the length of recovery time after physical exercise can be used as measures of cardiovascular fitness. It is important to highlight that more time is needed for the heart rate to return to its resting rate after more intense physical activities. For a healthy person doing low to moderate exercise, the heart rate will return to normal resting levels within 10-20 minutes.
