About this calculator
VO₂ Max (maximum oxygen uptake) is the gold standard physiological metric of cardiovascular fitness and aerobic endurance. It measures the maximum volume of oxygen your body can utilize per kilogram of body weight per minute during intense exercise.
This calculator computes estimated VO₂ Max from your performance on the standardized 12-Minute Cooper Run/Walk Test or resting heart rate, classifying your score against age- and sex-matched normative athletic standards.
How It Works & Formula
Cooper 12-Minute Test formula: VO₂ Max (mL/kg/min) = (Distance in meters - 504.9) / 44.73, or (Distance in miles × 35.97) - 11.29. Resting Heart Rate method: VO₂ Max ≈ 15.3 × (MHR / RHR).
