Introduction
VO2 Max Calculator — Estimate VO2 max from the Cooper 12-minute run test. Enter 12-minute run distance (meters) to get an instant, accurate result.
Formula
Cooper 12-minute run test (Cooper, 1968): VO2max (mL/kg/min) = (distance covered in 12 minutes, in meters − 504.9) / 44.73.
Step-by-step
- Enter the 12-minute run distance (meters).
- Click Calculate to see your result instantly.
Real-world example
Example: With 12-minute run distance (meters) = 2400 m, the VO2 Max Calculator gives a result of 42.3675.
Frequently Asked Questions
How do I measure the distance for this test?
Run or walk as far as you can in exactly 12 minutes on a track or measured route, then enter the total distance covered.
How accurate is the Cooper test compared to a lab VO2max test?
It's a well-validated field estimate correlated with lab-measured VO2max, but it's still an estimate — a treadmill gas-exchange test in a lab remains the gold standard.
What is VO2max used for?
It's a standard measure of aerobic fitness — the maximum rate your body can use oxygen during intense exercise — and is commonly used to track cardiovascular fitness over time.
What inputs does the VO2 Max Calculator need?
You'll need to provide: 12-minute run distance (meters). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the VO2 Max Calculator?
The VO2 Max Calculator applies the formula exactly as calculated — Cooper 12-minute run test (Cooper, 1968): VO2max (mL/kg/min) = (distance covered in 12 minutes, in meters − 504.9) / 44.73. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the VO2 Max Calculator free to use?
Yes, the VO2 Max Calculator is completely free, requires no signup, and runs instantly in your browser.
About the VO2 Max Calculator
The VO2 Max Calculator uses a real, verifiable formula — Cooper 12-minute run test (Cooper, 1968): VO2max (mL/kg/min) = (distance covered in 12 minutes, in meters − 504.9) / 44.73. — so results are accurate every time, not an approximation.
