Estimate VO2 max with Cooper, Rockport, 1.5-mile, or target-Cooper workflows while keeping each field-test protocol separate.
VO2 Max Field-Test Methods
VO2 max expresses peak aerobic oxygen use relative to body mass. Field tests estimate it from distance, time, heart rate, and demographic inputs; they do not directly measure expired gases. Use the mode that matches the test you actually performed.
Formula and Method
Cooper: VO2 max = (12-minute distance in meters – 504.9) / 44.73. Rockport: VO2 max = 132.853 – 0.0769(weight lb) – 0.3877(age) + 6.315(sex coefficient) – 3.2649(time min) – 0.1565(finish HR). The 1.5-mile mode uses VO2 max = 3.5 + 483 / time in minutes.
Field-test inputs must not be mixed
| Reference | Range or value | Use or interpretation |
|---|---|---|
| Cooper 12-minute run | Distance completed in 12 minutes | Running effort and pacing |
| Rockport one-mile walk | Weight, age, sex coefficient, time, finish HR | Brisk one-mile walk |
| 1.5-mile run | Completion time | Timed 1.5-mile run |
| Target Cooper | Desired VO2 max | Required 12-minute distance |
How to Use the Result
Use a measured course, record time precisely, and follow the named protocol. Repeat tests on comparable terrain, weather, equipment, and recovery status. Optional weight converts relative VO2 to an absolute oxygen-uptake estimate.
Assumptions and Limitations
Regression equations carry prediction error and may not fit every age, ability, disability, training status, or environmental condition. Stop a test for concerning symptoms and use supervised testing when appropriate.
