VO₂ Max Calculator (Cooper Test)
Estimate VO₂ max from the distance run in a 12-minute Cooper test.
Result
VO₂ max (ml/kg/min)
42.4
How it works
VO₂max = (distance − 504.9) ÷ 44.73
The Cooper test estimates aerobic fitness: run as far as you can in 12 minutes, then convert the distance to VO₂ max — the body’s maximum oxygen use.
