What is VO2 Max Calculator?
VO2 Max Calculator estimates aerobic capacity from the ratio of maximum to resting heart rate. VO2 max is a common indicator of cardiovascular fitness.
How It Works
The Uth-Sorensen-Overgaard-Pedersen formula estimates VO2 max as 15 multiplied by the maximum heart rate divided by the resting heart rate. Results are shown in ml/kg/min.
Common Use Cases
- Tracking aerobic fitness over time
- Comparing training progress
- Estimating cardio capacity without a lab test
- Setting endurance training targets
Technical Details
Performs the published heart-rate-ratio formula locally. The estimate is less precise than a laboratory gas-exchange test.
