VO2 max \u2014 the maximum volume of oxygen your body can use per minute \u2014 is one of the strongest single predictors of how long you will live. A 2018 JAMA study of 122,007 patients found that people in the lowest cardiorespiratory fitness quintile had a 5x higher risk of all-cause mortality than those in the elite quintile. The number is not just an athlete metric; it is a health metric that changes predictably with age.<\/p>\n

If you want to see how your own age interacts with fitness benchmarks, you can run the numbers through our life expectancy calculator<\/a> and compare your chronological age against the physiological profile typical for your cohort.<\/p>\n

What VO2 Max Actually Measures<\/h2>\n

VO2 max is expressed in milliliters of oxygen per kilogram of body weight per minute (mL\/kg\/min). It reflects three linked systems: how much blood your heart pumps per beat, how efficiently your muscles extract oxygen, and how well your lungs load oxygen into the bloodstream. Because all three decline with age, VO2 max falls on a fairly predictable curve.<\/p>\n

Average VO2 Max by Age and Sex<\/h2>\n

The table below shows typical values for moderately active adults. “Moderately active” means 150+ minutes of moderate exercise per week \u2014 not a trained athlete, not sedentary.<\/p>\n

The 10% Rule \u2014 and Why It Is Not Fate<\/h2>\n

Untrained adults lose roughly 10% of VO2 max per decade after age 30. Two mechanisms drive it: a decline in maximum heart rate (about 1 beat per year, so 220 minus age is the classic estimate) and a loss of muscle mitochondrial density.<\/p>\n

But longitudinal studies of masters athletes show the decline can be cut to 5% per decade with consistent training. A 70-year-old who has trained for 40 years can post a VO2 max matching an untrained 40-year-old. The curve is a default, not a ceiling.<\/p>\n

How to Estimate Your Own Number<\/h2>\n

You do not need a lab. The Cooper 1.5-mile test and the 12-minute run test both give estimates within 10-15% of a true lab value. A rough field formula for the 12-minute test:<\/p>\n

VO2 max \u2248 (distance in meters \u2212 504.9) \u00f7 44.73<\/strong><\/p>\n

For example, running 2,400 meters in 12 minutes gives approximately (2400 \u2212 504.9) \u00f7 44.73 \u2248 42.4 mL\/kg\/min \u2014 solidly in the “good” band for a 35-year-old man.<\/p>\n
