How close is heart rate to the percent of VO2max? Turns out it’s pretty close. Here’s my VO2max testing data.
The R^2 of 0.9676 indicates a very good fit. The formula is:
%VO2max = (0.0101 * HR) – 0.6486
Or the other way around
HR = (%VO2max+.6486)/0.0101
Now I have an easy way to convert between the two numbers. I would not know this without the VO2max testing.
VO2max in the equations is in the range of 0.0 to 1.00 (0 to 100%).
