Question

Answer 1

70% to 85%

Step-by-step explanation:

During exercise, our heart tends to beat faster so that more oxygen could be supplied to the cells. The level of the intensity of the physical activity interprets how faster the heart shall work to meet up the supply.

The American Heart Association suggests that the heart rate shall increase by 50% to about 70% for moderate type physical activities. The American Heart Association also suggests that the heart rate shall increase by 70% to about 85% of the normal heart rate for high intensity exercises.
