How to Convert Oven Recipes to Air Fryer
This calculator estimates your VO2 max (maximal oxygen uptake) using validated exercise test formulas. VO2 max is the gold standard measure of cardiovascular fitness and a strong predictor of longevity.
The basic rule:
- Cooper test: VO2max = (distance_meters − 504.9) / 44.73
- Rockport 1-mile walk: uses body weight, walk time, and ending heart rate in a regression formula
- 3-min step test: uses recovery heart rate after 3 minutes of stepping at a set cadence
- Resting estimate: uses age and gender norms (least accurate but requires no test)
VO2 max is one of the strongest predictors of all-cause mortality. Research shows that moving from the bottom 25th percentile to above the 50th percentile reduces mortality risk by 50%. Elite endurance athletes typically have VO2 max values of 60-85 ml/kg/min.

Frequently Asked Questions
What is a good VO2 max?
For men: poor is below 35, fair is 35-40, good is 40-48, excellent is 48-55, and superior is above 55 ml/kg/min. For women: poor is below 28, fair is 28-34, good is 34-41, excellent is 41-48, and superior is above 48. These ranges shift downward with age.
How is the Cooper test performed?
Run as far as possible in exactly 12 minutes on a flat surface (track is ideal). Record your total distance in meters. Walk if needed but try to maintain the highest sustainable pace. Warm up for 5-10 minutes before starting. The test works best for people already doing regular cardio.
Why does VO2 max matter for longevity?
A landmark 2022 study of 750,000+ people found that low VO2 max is as dangerous as smoking for mortality risk. Moving from the bottom 25% to above-average fitness reduced death risk by 50%. Peter Attia considers VO2 max the single most powerful marker of longevity.
Can I improve my VO2 max?
Yes. Untrained individuals can improve VO2 max by 15-20% with consistent training. The most effective methods are Zone 2 training (3-4 hours/week) combined with high-intensity intervals (1-2 sessions/week of 4x4 minute intervals at 90-95% max HR). Improvements are seen within 6-8 weeks.
How accurate are these estimates?
The Cooper test is most accurate (correlation of 0.90 with lab testing). The Rockport walk test is good for less fit individuals. Step tests are moderate accuracy. Resting estimates are the least accurate. For precise measurement, a lab-based graded exercise test with gas analysis is the gold standard.
What does the Apple Watch VO2 max mean?
Apple Watch estimates VO2 max using heart rate data during outdoor walks/runs. It tends to underestimate for fit individuals and has moderate accuracy (within 5-10 ml/kg/min). Use it for tracking trends over time rather than absolute values. A proper field test like the Cooper test is more reliable.
