  1. Enter the distance covered in a 12-minute Cooper test run.
  2. VO2 max estimates using the formula (distance in meters − 504.9) ÷ 44.73.

Limitations

  • This is a field-test approximation, not a lab-measured VO2 max — useful for tracking your own progress over time rather than an exact clinical number.
