Formula

VO2max = 132.853 − 0.0769W − 0.3877A + 6.315G − 3.2649T − 0.1565HR

= 42.438

Frequently asked questions

What does the Rockport Walk Test estimate?+

It estimates your VO2max, the maximum rate at which your body can consume oxygen during intense exercise, which is considered one of the best overall indicators of cardiovascular fitness. The test is designed as an accessible alternative to lab-based VO2max testing, using a timed one-mile walk instead of a treadmill or lab equipment.

How does the test convert my walk time and heart rate into VO2max?+

The Rockport formula uses your time to walk one mile as fast as possible, your heart rate immediately at the end of the walk, along with your age, sex, and weight, plugging them into a regression equation developed from research correlating these factors with lab-measured VO2max. The result is an estimate, not a direct physiological measurement.

Why must I walk, not run, for this test to be accurate?+

The formula was specifically calibrated using walking data, so running the mile would produce a heart rate and pace relationship that doesn't match the equation's assumptions, making the resulting VO2max estimate inaccurate. The test requires walking as fast as possible without breaking into a run.

How accurate is this estimate compared to a lab VO2max test?+

It's generally considered a reasonably good field estimate for the general population, though it tends to be less precise for very fit individuals or those with atypical heart rate responses. Lab-based testing with metabolic gas analysis remains the gold standard for a precise measurement.

What does my VO2max number tell me about my fitness level?+

Higher VO2max values indicate a greater capacity for sustained aerobic exercise and are generally associated with better cardiovascular health and endurance performance, with typical values compared against age and sex norms. Tracking VO2max over time is often more useful than a single reading for monitoring fitness improvements.
