VO2 Max Calculator
Estimate VO2 max from resting and maximum heart rate using the heart-rate ratio method.
| Heart Rate | bpm |
|---|---|
| Resting heart rate | |
| Maximum heart rate |
How to Use the VO2 Max Calculator
Enter the requested test values, such as time, distance or heart-rate information, and calculate an estimated VO2 max. The result provides a general indication of aerobic fitness rather than a laboratory measurement.
Practical Example
If a runner completes the selected field test with a performance associated with a VO2 max near 45 mL/kg/min, the calculator reports that estimate for comparison and training context.
Factors That Affect the Result
Test protocol, pacing, environmental conditions, fatigue, heart-rate accuracy, age and training status can all influence the estimate.
Frequently Asked Questions
What does VO2 max measure?
It estimates the maximum amount of oxygen your body can use during intense exercise.
Is a field-test VO2 max exact?
No. Laboratory testing with respiratory equipment is more precise.
Can VO2 max improve with training?
Yes. Aerobic training can improve VO2 max, especially in previously untrained individuals.
