What is the equation for target HR using the HRR method?
Target HR = (Max HR + resting HR) x percentage
Target HR = resting HR x HRmax
Target HR = [(HRmax − resting HR) x percentage] + resting HR
Target HR = Max HR / Resting HR x percentage
The correct answer is: Target HR = [(HRmax − resting HR) x percentage] + resting HR
The other options are incorrect because they do not take into account the resting heart rate. Option A adds the resting heart rate to the maximum heart rate before multiplying by the percentage, while option B only uses the resting heart rate and not the maximum heart rate. Option D multiplies the maximum heart rate by the percentage and then divides by the resting heart rate, which does not follow the formula for HRR. Only option C correctly follows the formula by subtracting the resting heart rate from the maximum heart rate and then adding back the resting heart rate after multiplying by the percentage.
