VO2 Max Calculator

This tool estimates VO2 max, the amount of oxygen your body can use at full effort, from four field tests that need no lab equipment. Pick the test you did: a Cooper 12 minute run, a timed 1.5 mile run, the Rockport 1 mile walk with your finishing heart rate, or the ratio of your maximum to your resting heart rate. Each option uses the published regression for that test, so the answer is an estimate fitted to a group of people rather than a measurement of you. Results are shown in ml/kg/min with the equivalent in METs beside them.

Calculator Type
Distance In
Cooper fitted this regression on metres, so a distance in yards or miles is converted to metres before it goes in. A 400 metre track is a 400 metre track everywhere; four laps is 1,600 metres, not a mile.

The 1.5 miles is the test, not a unit: it is 2,414 metres, or six laps of a 400 metre track plus 14 metres.

Weight In
Kline and colleagues fitted this equation on pounds, so a weight in kilograms is converted before it goes in. The answer is in ml per kilogram per minute either way.
The mile is the test, not a unit: it is 1,609 metres, or four laps of a 400 metre track plus 9 metres.

Measured if you have it; otherwise roughly 220 minus your age.
