Cooper Test VO₂max Calculator
Estimate VO₂max from the 12-minute Cooper running test using Cooper's 1968 formula.
How to Use the Cooper Test VO₂max Calculator
- Warm up thoroughly.
- Run as far as possible in exactly 12 minutes on a flat surface (track works best).
- Enter the distance in metres.
- Click Calculate to see VO₂max and rating.
Use Cases
- •Field fitness assessment in schools and military units.
- •Baseline testing before starting a training program.
- •Tracking aerobic progress over time.
Formula
VO₂max (ml/kg/min) = (distance in metres − 504.9) / 44.73. Run as far as possible in exactly 12 minutes on a flat surface.
Frequently Asked Questions
What is VO₂max?
VO₂max is the maximum rate at which your body can use oxygen during exercise. It is a strong predictor of aerobic fitness and endurance performance.
How accurate is the Cooper test?
The Cooper test correlates reasonably well (r ≈ 0.8) with laboratory-measured VO₂max in healthy adults who pace the 12-minute effort well. Lab treadmill tests remain the gold standard.
Any contraindications?
Maximal effort testing is not appropriate for untrained beginners, people with cardiovascular risk factors, or anyone with injuries. Get medical clearance first.
