Heart Rate Reserve (HRR) is the difference between your Maximum Heart Rate (HRmax) and Resting Heart Rate (HRrest). Exercise intensity can be evaluated by comparing your heart rate as a percentage of HRR.
Contents
1 Calculating Heart Rate Reserve
The calculation to work out %HRR is (HRex – HRrest)/(HRmax – HRrest), where HRex is the exercise Heart Rate. For example a HRmax of 180, a HRrest of 40 and HRex of 140 would be (140 – 40)/(180 – 40), which is 71%.
2 Why %HRR rather than %HRmax
Using %HRR is better than a percentage of HRmax. as it reflects the relative intensity more accurately. For example, if two athletes both have a HRmax of 180, but one has a HRrest of 40 and the other 70, at HRex of 140would be same %HRmax, but one is at 64 %HRR and the other is at 71 %HRR.
3 Estimating percent V̇O2max
It is possible to estimate the percent of V̇O2max from the percent of HRR using the formula
%V̇O2max = (%MHR - 37) / 0.64
