Which factor will decrease in response to increased cardiorespiratory fitness?
a) physical fitness
b) cardiorespiratory endurance

D) Resting heart rate.

Explanation:

For example, exercise, associated with lower resting heart rate and control metabolic syndrome, is uniformly critical as a method to lower the risk of acquiring the atherosclerotic cardiovascular disorder. From these conclusions, it can be hypothesized that great cardiorespiratory fitness is essential for reducing the resting heart rate.

the answer would be
