Question

How do you calculate % HR reserve? and then target HR?

a) HR Reserve = Max HR - Resting HR; Target HR = HR Reserve * Desired Percentage + Resting HR
b) HR Reserve = Resting HR - Max HR; Target HR = HR Reserve * Desired Percentage + Max HR
c) HR Reserve = Max HR + Resting HR; Target HR = HR Reserve * Desired Percentage - Resting HR
d) HR Reserve = Max HR * Resting HR; Target HR = HR Reserve * Desired Percentage / Resting HR

Answer 1

To calculate % HR reserve, subtract the resting heart rate from the maximum heart rate, and to calculate the target heart rate, multiply the HR reserve by the desired percentage and add the resting heart rate.

Step-by-step explanation:

The correct formula to calculate % HR reserve is:

HR Reserve = Max HR - Resting HR;

Target HR = HR Reserve * Desired Percentage + Resting HR

For example, let's say an individual has a maximum heart rate (Max HR) of 200 bpm and a resting heart rate (Resting HR) of 60 bpm. To calculate the HR Reserve, you would subtract the Resting HR from the Max HR: HR Reserve = 200 - 60 = 140 bpm.

To calculate the Target HR, you would multiply the HR Reserve by the desired percentage (e.g., 70%) and add the Resting HR: Target HR = 140 * 0.70 + 60 = 158 bpm.
