Heart rate recovery (HRR) refers specifically to the decrease in heart rate from its peak value back down to a lower level after the cessation of physical activity. To clarify, HRR is measured by determining how much the heart rate decreases during a defined recovery period, typically the first minute after exercise.

The correct choice highlights the relationship between resting heart rate (HRrest) and peak heart rate (HRmax). In this context, the difference between HRrest and HRmax provides valuable insights into cardiovascular fitness and the efficiency of the heart's response to exercise. A more significant drop in heart rate after exercise indicates better cardiovascular fitness, as a well-conditioned heart tends to recover more quickly.

Increased HRR tends to correlate with improved heart health and aerobic capacity, making it an important metric in assessing an individual’s recovery process after intense exercise.
