VO2 Max Calculator by Age and Sex

Key takeaways

A good VO2 max depends on your age and sex. In the U.S. FRIEND registry, the median for adults in their 40s is about 27 ml/kg/min for women and 38 for men, with roughly 32 and 45 marking the top quarter. Values fall about 10% per decade, yet aerobic fitness stays trainable at every age.

How this calculator works

Percentiles come from the FRIEND registry: 7,783 maximal treadmill breath tests from U.S. adults without cardiovascular disease. We interpolate between the published 5th–95th percentile points for your age decade and sex. Cycle tests usually read a little lower than treadmill tests. The resting-heart-rate option uses the Uth–Sørensen–Overgaard–Pedersen formula with an age-predicted maximum heart rate.
