What this calculator tells you

The Cooper test uses distance covered in 12 minutes as a field estimate of aerobic capacity. It is accessible, demanding, and best repeated under similar conditions.

How to use the VO₂ Max Calculator

  1. 1

    Use a measured flat course after an appropriate warm-up.

  2. 2

    Cover as much distance as safely possible in exactly 12 minutes.

  3. 3

    Enter distance and compare only with similarly conducted tests.

Formula and interpretation

Method

Estimated VO₂ max (mL/kg/min) = (distance in metres − 504.9) ÷ 44.73.

How to read the result

Compare repeated tests on the same surface and under similar weather. The trend is more useful than treating one number as a lab measurement.

Important limitations

This is a maximal running test and may be unsuitable without medical clearance or running preparation. Motivation, pacing, weather, and surface affect the result.

VO₂ Max Calculator questions

Is this the same as a lab VO₂ max test?

No. It is a field estimate; a metabolic-cart test directly measures respiratory gases.

Can I walk the Cooper test?

You can mix running and walking, but the equation and interpretation are most useful when the test reflects a maximal safe effort.
