<span>a. 40% to 50%
b. 50% to 70%
c. 70% to 85%
d. 85% to 100%
The correct answer is 50% to 70%. Moderate-intensity activity is noted when a person reaches 50% to 70% of his or her maximum heart rate in exercise. The maximum heart rate is determined by subtracting the age to 220.
<em>For example, a 54-year-old male with type 2 diabetes needs to have moderate intensity activity. His maximum heart rate is (220-54) which is 166 bpm. 50% to 70% of 166 is 83-116 bpm. Therefore he should exercise and raise his heart rate at 83-116 bpm. </em>
