What is the difference between maximal heart rate and resting heart rate known as?

The difference between maximal heart rate and resting heart rate is known as Heart Rate Reserve (HRR). Heart Rate Reserve represents the range of heart rates available for exercise intensity calculation. It is determined by subtracting the resting heart rate from the maximal heart rate, providing a clear understanding of how much cardiovascular capacity an individual has available for physical activity.

This value is crucial for developing personalized training programs, as it helps determine appropriate exercise intensities based on the individual’s fitness level and lung capacity. Heart Rate Reserve is often used in conjunction with Karvonen’s formula to establish target heart rates for aerobic training.

In contrast, other terms such as Target Heart Rate refer to specific heart rates targeted during exercise, while Maximum Heart Rate and Resting Heart Rate are static values and don’t represent the difference between the two. Only Heart Rate Reserve encapsulates the entire range of heart activity available for exercise.
