Which of the following is an indication of better cardiovascular fitness according to the Harvard Step Test?

A quicker heart rate recovery is recognized as an indication of better cardiovascular fitness in the context of the Harvard Step Test. This test evaluates an individual's cardiovascular endurance by measuring how quickly their heart rate returns to baseline levels following exercise.

When a person engages in physical activity, their heart rate increases to supply more oxygen to the muscles. An efficient cardiovascular system, typically associated with regular aerobic exercise, allows for a faster return to resting heart rate after the cessation of activity. Therefore, a quicker recovery time signifies that the heart and overall cardiovascular system are functioning efficiently and are fit.

In contrast, other options indicate less favorable cardiovascular fitness. A slower heart rate recovery suggests poorer fitness levels, as it reflects a lack of conditioning in the cardiovascular system. A higher resting heart rate is generally associated with less cardiovascular efficiency and increased workload on the heart. Lastly, a consistent heart rate during exercise may indicate a lack of intensity in the workout, which would not be an optimal sign of cardiovascular fitness.
