Rockport VO2 max test (1-mile walk)
The Rockport test estimates VO2 max from a one-mile (~1,609 m) walk. You cover the distance as fast as you can, but you keep a walking gait the whole way. No running. Here is the formula: VO2max = 132.853 − 0.0769·weight(lb) − 0.3877·age + 6.315·(sex: 1=M / 0=F) − 3.2649·time(min) − 0.1565·HRfinal. It was built for adults and validated for ages 30 and up. Example: a 30-year-old man, 70 kg (≈154 lb), 14 minutes, final HR 140 → VO2max ≈ 132.853 − 0.0769·154 − 0.3877·30 + 6.315·1 − 3.2649·14 − 0.1565·140 ≈ 43 mL/kg/min. It works well for older adults and beginners who can't safely run a Cooper test.
Applications: clinical and population
The American College of Sports Medicine (ACSM) recommends it for clinical assessment of older adults and cardiopulmonary rehabilitation, as well as for people who face mobility or cardiovascular limitations. You'll also see it in occupational screening, in fitness baselines for sedentary adults, and as a way to track progress over time when ergospirometry isn't available. It puts far less stress on the body than a running test, and you can repeat it reliably on any 400 m track or a measured walking path.
FAQ
Can I run during the test? No. The validation assumes you're walking, so running throws the equation off.
How do I measure final HR? Take it the moment you finish the mile, using a chest strap or wrist monitor. Counting your pulse by hand works too, though it's less precise.
Is it accurate for young people? The formula was validated in adults 30 and older, and it tends to come in low for younger, fitter people.
How often should I repeat it? Every 6-12 weeks is about right. That spacing lets real training gains show up before random measurement noise drowns them out.
