1.Define heart rate reserve.

Jun 10th, 2015

Heart rate reserve (HRR) is the difference between resting heart rate (HRrest) and maximum heart rate (HRmax).

HRR = HRmax - HRrest

Heart rate reserve is used when determining exercise heart rates. 

The Karvonen formula is used to calculate exercise heart rate at a given percentage training intensity. Add the given percentage of heart rate reserve to the resting heart rate.

Exercise HR = % of target intensity (HRmax – HRrest) + HRrest

For example: Target intensity 70 % HRR for a person with HRmax 201 bpm and 
HRrest 50 bpm

Exercise HR= 70% (201-50=151) + 50
