Engaging in more physically demanding exercise displays a positive correlation with pulse rate. High-intensity exercise causes the cardiopulmonary system to work harder, which increases the number of beats per minute.
The resting heart rate is the baseline of measurement for when the body is at rest. It is found by counting the number of beats in a minute. The body's maximum heart rate is found by subtracting an individual's age from 220. For optimal health, it is recommended to engage in cardiovascular exercise within the target heart range, which is 50 to 85 percent of the maximum heart rate.
