Estimate VO₂ max from a 12-minute run
The Cooper Test is a simple field test: run or cover as much distance as possible in 12 minutes. ATHLOMETRY converts the final distance into an estimated VO₂ max and also shows the average speed and pace of the effort.

Cooper Test VO₂ max formula
VO₂ max ≈ (distance in metres − 504.9) ÷ 44.73
The result is expressed in ml·kg⁻¹·min⁻¹. It is an indirect estimate based on running performance, not a laboratory measurement of oxygen uptake.
How to perform the test consistently
- Use a measured track or reliably measured flat route.
- Warm up before starting.
- Cover the greatest sustainable distance you can in exactly 12 minutes.
- Record the final distance accurately.
- For progress tracking, repeat the test under similar surface, weather and pacing conditions.
How accurate is the Cooper Test?
Research supports the Cooper Test as a practical and generally reliable field assessment, but agreement with laboratory VO₂ max varies between populations and fitness levels. Use it for practical monitoring rather than treating the predicted value as identical to respiratory-gas analysis.
Does the Cooper Test directly measure VO₂ max?
No. It predicts VO₂ max from distance covered. Direct measurement requires respiratory-gas analysis during a maximal exercise test.
Can I do it on a treadmill?
You can perform a 12-minute effort on a treadmill, but results may not be directly comparable with outdoor track testing because pacing, mechanics and environment differ.
What should I compare over time?
Distance is the most direct field-test outcome. You can also monitor the estimated VO₂ max, but keep the testing protocol consistent.
Is a higher result always better?
A greater distance and estimated VO₂ max generally indicate better aerobic performance, but sport demands, age, training phase and test conditions matter.
