VO2 Max Formula
Estimate maximum oxygen uptake during exercise.
The gold standard measure of cardiovascular fitness.
The Formula
VO2 max = 15.3 × (HR_max / HR_rest)
VO2 max measures the maximum volume of oxygen your body can use during intense exercise. Higher values indicate better cardiovascular fitness. This simplified formula provides an estimate.
Variables
| Symbol | Meaning |
|---|---|
| VO2 max | Maximum oxygen consumption (mL/kg/min) |
| HR_max | Maximum heart rate (usually estimated as 220 - age) |
| HR_rest | Resting heart rate (beats per minute) |
Example 1
A 30-year-old with a resting heart rate of 65 bpm
HR_max = 220 - 30 = 190 bpm
VO2 max = 15.3 × (190 / 65)
VO2 max ≈ 44.7 mL/kg/min (good fitness level)
Example 2
A 50-year-old with a resting heart rate of 75 bpm
HR_max = 220 - 50 = 170 bpm
VO2 max = 15.3 × (170 / 75)
VO2 max ≈ 34.7 mL/kg/min (average fitness level)
When to Use It
Use the VO2 max formula when:
- Assessing cardiovascular fitness without lab equipment
- Tracking fitness improvements over time
- Setting training intensity based on fitness level
- Comparing fitness across different age groups
