VO2max Calculator
Estimate your aerobic fitness two ways.
For the Cooper test, run as far as you can in 12 minutes on a flat track. The heart rate method (Uth et al.) needs a real max heart rate, not 220 minus age, to be useful.
Formula: Cooper: (metres − 504.9) ÷ 44.73. Heart rate: 15.3 × HRmax ÷ HRrest
