How to Use the VO₂max Calculator
- Select a test – Choose either Rockport 1-Mile Walk or Cooper 12-Minute Run from the dropdown.
- Fill in the required fields:
- For Rockport: gender, age (18–99 years), weight (in pounds), walk time (minutes and seconds), and heart rate at the end (bpm).
- For Cooper: distance covered in 12 minutes (in meters).
- Click “Calculate VO₂max” – Your estimated maximal oxygen uptake (in ml/kg/min) and fitness category will appear instantly.
- Interpret the result – A higher value indicates better aerobic fitness. Categories range from Very Poor to Superior.
Note: All inputs use imperial units (lbs) for weight and metric (meters) for distance. Ensure times are entered in minutes and seconds.

Frequently Asked Questions
VO2max is the maximum rate of oxygen consumption measured during incremental exercise. It is an indicator of aerobic endurance and cardiovascular fitness.
This calculator uses validated formulas from the Rockport and Cooper tests, which are well-established field tests. However, actual VO2max measured in a lab may vary.
The Rockport test is suitable for those who can walk briskly for 1 mile, while the Cooper test is for those who can run for 12 minutes. Choose based on your fitness level.
