Frequently Asked Questions

What is the Cooper 12-Minute Run Test?

Created by Dr. Kenneth Cooper in 1968 for the US Air Force, the 12-minute test measures how far a person can run or jog in exactly 12 minutes, serving as a reliable non-laboratory field estimate of maximal oxygen uptake (VO2max).

What is the mathematical formula used to calculate VO2max from the Cooper test?

The standard formula is: VO2max (ml/kg/min) = (Distance in meters - 504.9) / 44.73 (or in miles: [35.97 x miles] - 11.29).

What distance represents excellent aerobic fitness?

For men under 40, running over 2,700 meters (~1.68 miles or 6.75 track laps) is considered excellent. For women under 40, running over 2,500 meters (~1.55 miles) is excellent.

How should the Cooper test be performed?

Perform a 10-minute warm-up, run at a steady maximum sustainable pace on a flat 400-meter running track or calibrated GPS course for exactly 12:00 minutes, and measure total distance covered to the nearest 10 meters.
