Rockport Walk Test Calculator (VO₂max)
Estimated aerobic fitness (VO₂max) from the Rockport one-mile walk test: walk 1609 m as fast as you can and note the time and your heart rate at the finish.

What this tool does
The Rockport test was developed for people for whom a running test is too hard: you walk one mile (1609 m) briskly on a flat course, then take your pulse immediately. The regression of Kline and colleagues (1987) turns weight, age, sex, time and heart rate into an estimate of VO₂max, the most oxygen the body can use. Like all field tests it has an error of several units for an individual, so it is best for tracking your own progress over time. Check with a doctor before exercise testing if you have heart problems or have been inactive.
Formula
VO₂max = 132.853 − 0.0769 W(lb) − 0.3877 age + 6.315 sex − 3.2649 t(min) − 0.1565 HR (Kline et al., 1987)
