Question

question 3 of 5 why is it best to have a resting heart rate below 70 beats per minute? a. people with resting heart rates above 70 bpm cannot reap the same benefits of exercise. b. people with resting heart rates above 70 bpm are at higher risk for heart disease. c. people with resting heart rates below 70 bpm can pump more blood per minute. d. people with resting heart rates below 70 bpm have higher metabolism rates.

Explanation:

A lower resting heart rate is often associated with better heart - health. Higher resting heart rates are linked to an increased risk of heart disease. Option A is incorrect as people with higher resting heart rates can still benefit from exercise. Option C is wrong because the ability to pump more blood per minute isn't directly related to resting heart rate being below 70 bpm. Option D is incorrect as resting heart rate below 70 bpm doesn't necessarily mean higher metabolism rates.

Answer:

B. People with resting heart rates above 70 bpm are at higher risk for heart disease.
