VO2 Max Chart by Age and Gender
VO2 max (maximal oxygen consumption) is the gold standard measure of cardiorespiratory fitness, expressed in mL/kg/min. It represents the maximum rate at which your body can use oxygen during intense exercise. Higher VO2 max values are strongly associated with reduced cardiovascular mortality and all-cause mortality. This chart classifies VO2 max by age, gender, and fitness level based on ACSM normative data.

How to Interpret This Data
VO2 max is measured directly through a cardiopulmonary exercise test (CPET), where expired gas analysis determines oxygen consumption during graded exercise to exhaustion. However, many wearable devices and fitness tests estimate VO2 max from submaximal exercise data using heart rate response, pace, and age — these estimates typically have an error margin of 3–5 mL/kg/min compared to direct measurement.
VO2 max declines approximately 5–10% per decade after age 25–30, even in individuals who maintain regular exercise. However, this rate of decline is substantially slower in physically active individuals compared to sedentary ones. A landmark JAMA study by Mandsager et al. (2018) found that cardiorespiratory fitness was inversely associated with all-cause mortality with no upper limit of benefit — meaning higher fitness was always associated with lower death risk. Individuals in the lowest 25th percentile of fitness had a mortality risk comparable to or exceeding smoking, diabetes, and coronary artery disease.
Women have lower average VO2 max values than men across all age groups, primarily due to lower hemoglobin concentrations, smaller heart size, lower muscle mass, and higher essential body fat percentage. This sex difference is approximately 15–25% and narrows when VO2 max is expressed relative to lean body mass rather than total body weight. For health benefits, achieving at least a "Good" fitness classification for your age and gender is associated with significantly reduced cardiovascular risk. Moving from "Very Poor" to "Poor" or from "Poor" to "Fair" provides the greatest relative mortality reduction.
Frequently Asked Questions
How accurate are wearable VO2 max estimates?
Wearable devices (Apple Watch, Garmin, Fitbit) estimate VO2 max using heart rate, pace, and demographic data with typical errors of 3–5 mL/kg/min compared to direct lab measurement. These estimates are most accurate during outdoor runs on flat terrain and less accurate during walking, cycling, or indoor exercise. They are useful for tracking trends over time but should not be used for clinical decision-making.
Can you improve VO2 max at any age?
Yes. Research shows VO2 max can be improved by 10–30% with structured aerobic training regardless of starting age. High-intensity interval training (HIIT) produces the fastest VO2 max improvements (5–8% in 6–12 weeks), while consistent moderate-intensity exercise produces more gradual but sustained gains. Even individuals in their 70s and 80s can meaningfully improve VO2 max with appropriate training.
What is a good VO2 max for longevity?
A VO2 max above the 50th percentile for your age and gender is associated with significantly reduced cardiovascular and all-cause mortality. However, the greatest longevity benefit comes from avoiding the bottom 25th percentile. For a 50-year-old male, a VO2 max above 37 mL/kg/min places you in the 'Good' category. Each 1 MET (3.5 mL/kg/min) increase in fitness is associated with approximately 12–15% reduction in mortality risk.
