Overview
What Is VO2 Max?
VO2 max measures the maximum rate of oxygen your body can use during intense exercise, a key indicator of aerobic fitness.
Estimate your VO2 max from run time.
VO2 max measures the maximum rate of oxygen your body can use during intense exercise, a key indicator of aerobic fitness.
Useful for tracking cardiovascular fitness progress and comparing to general fitness benchmarks.

The maximum amount of oxygen your body can utilize during intense exercise, measured in mL/kg/min - a key aerobic fitness indicator.
It provides a reasonable estimate for many people, though laboratory testing with metabolic gas analysis is the gold standard for precision.
This varies significantly by age, sex, and fitness level - elite endurance athletes often have much higher values than sedentary individuals.
Yes, consistent aerobic training (particularly higher-intensity interval training) is generally effective for improving VO2 max over time.

A standard field-test formula that estimates VO2 max from 1.5-mile run time performance.
Yes, VO2 max typically peaks in young adulthood and gradually declines with age, though training can offset some decline.
VO2 max benchmarks are often presented separately by sex due to average physiological differences, though this basic calculator provides one general estimate.
No, this is a general fitness estimation tool - consult a healthcare provider before starting intense exercise testing.
