Frequently Asked Questions
What is VO2 max?
VO2 max is the maximum volume of oxygen your body can use per minute during intense exercise. It is often expressed in ml/kg/min and is a common measure of aerobic fitness. Higher values generally mean better cardiovascular fitness.
How is VO2 max calculated?
Lab testing is most accurate. Estimates can come from run tests (e.g. Cooper 12-minute run distance, or time for 1.5 miles). This calculator uses distance covered in 12 minutes (Cooper test) to estimate VO2 max in ml/kg/min.
Is the VO2 max calculator accurate?
It gives an estimate from the Cooper formula. Actual VO2 max varies with pacing, terrain and fitness. For a precise value, use lab or gas analysis.
What is a good VO2 max?
Depends on age and sex. For adults, rough ranges: men 35–45+ ml/kg/min, women 30–40+ ml/kg/min for average to good. Elite endurance athletes often exceed 50–60+. Charts by age/sex are available online.
