At rest, my heart rate is 60 BPM. With exercise, it goes up to 90 BPM. What percent increase is this?
|
|
30/60 = 50%
|
|
|
90-60 = 30%

60/90 = 67%
|
|
|
30/90 = 33%

Explanation:
Detailed explanation-1: -To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100.
Detailed explanation-2: -The more intense the exercise is the longer it will take for heart rate to return to its resting rate. With low-moderate intensity aerobic fitness training (as indicated in the graph) heart rates return to normal within 10-20 minutes.
