Question

which indicates the hearts efficiency at rest and provides a baseline for determining exercise intensity?
o blood pressure (bp)
o target heart rate (thr)
o resting heart rate (rhr)
o maximum heart rate (mhr)

Explanation:

Resting heart rate (RHR) measures how many times the heart beats per minute while at rest. A lower RHR often indicates a more efficient heart. It also serves as a starting - point for calculating target heart rates during exercise. Blood pressure measures the force of blood against artery walls, target heart rate is for exercise intensity, and maximum heart rate is the highest rate during intense exertion.

Answer:

C. resting heart rate (RHR)
