Field estimates of VO2max
Cooper: distance covered in 12 minutes. Rockport: a fast 1-mile walk (1609.344 m), elapsed time and finishing heart rate; originally tested in healthy adults aged 30–69. Uth: 15.3 × HRmax / HRrest; tested in well-trained men aged 21–51.

Calculation
This calculation is for reference only and is not medical advice, a diagnosis or a prescription. If you have a medical condition, are pregnant, take medication or have any doubts, discuss the result with a physician or a qualified nutrition professional.
Result
- VO2 Max
- 44.6 mL/kg/min
These are indirect estimates, not gas-exchange measurements. Uth is not extrapolated here to women, or Rockport outside its stated age range. An age-predicted maximum heart rate adds uncertainty. Negative estimates, fitness categories and 5/10 km pace predictions are not provided.

How it is calculated
Cooper: distance covered in 12 minutes. Rockport: a fast 1-mile walk (1609.344 m), elapsed time and finishing heart rate; originally tested in healthy adults aged 30–69. Uth: 15.3 × HRmax / HRrest; tested in well-trained men aged 21–51.
Formula
Cooper: distance covered in 12 minutes. Rockport: a fast 1-mile walk (1609.344 m), elapsed time and finishing heart rate; originally tested in healthy adults aged 30–69. Uth: 15.3 × HRmax / HRrest; tested in well-trained men aged 21–51.
Limits of the method
These are indirect estimates, not gas-exchange measurements. Uth is not extrapolated here to women, or Rockport outside its stated age range. An age-predicted maximum heart rate adds uncertainty. Negative estimates, fitness categories and 5/10 km pace predictions are not provided.
