Cooper 12-Minute Run

Estimate maximal aerobic capacity (VO2max) from a maximal-effort running test.

Equipment

Flat track or measured route, stopwatch, cones or markers.

The protocol
  1. 01Warm up for 5-10 minutes with light jogging and dynamic stretches.
  2. 02Mark a flat course (ideally a running track).
  3. 03On "Go", the client runs as far as possible in exactly 12 minutes.
  4. 04Pace should be as even as possible — starting too fast leads to early fatigue.
  5. 05At 12 minutes, stop and measure total distance covered in metres.
  6. 06Cool down with 5 minutes of walking.
What to watch for
  • Client starting too fast and fading significantly.
  • Not warming up adequately.
  • Running on uneven or hilly terrain (should be flat).
  • Signs of distress — stop if the client shows chest pain, dizziness, or extreme breathlessness.
Normative scoring

VO2max = (distance in metres - 504.9) / 44.73. Men (age 20-29): >2800 m excellent. Women (age 20-29): >2700 m excellent. Declines with age. Used to classify aerobic fitness.
