How the VO2 Max Calculator works

VO₂ max is the most oxygen your body can use during hard exercise, per kilogram of body weight per minute — a key measure of aerobic fitness. Kenneth Cooper's 1968 test estimates it from one run: after a warm-up, cover as much distance as you can in 12 minutes on a flat track, then enter the distance.

Formula

VO₂ max = (distance in metres − 504.9) ÷ 44.73

In ml of oxygen per kg per minute.

Examples

2,400 metres

(2,400 − 504.9) ÷ 44.73 ≈ 42.4 ml/kg/min.

3,000 metres

(3,000 − 504.9) ÷ 44.73 ≈ 55.8 ml/kg/min.

Frequently asked questions

How accurate is the Cooper test?

It tracks lab results well for trained runners who pace the 12 minutes well, and less well for beginners. A lab treadmill test measures VO₂ max directly.

Can I use a treadmill?

Yes, at a 1% incline to make up for the lack of air resistance, but results can differ from a track.

Is the test safe for everyone?

It's an all-out effort. If you have a heart or lung condition or are new to exercise, check with a doctor first. This is general information, not medical advice.
