Question

During physical activity of moderate intensity, your heart will beat at a percentage of its maximum rate. What is the target heart rate for moderate-intensity activity? 40% to 50%

Answer 1

There are choices for this question namely: 

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. 

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.
