Two maximal-effort distance-running field tests — run 1.5 miles as fast as possible, or cover as much ground as possible in 12 minutes — converted to estimated VO2max by regression equations.
Detail
Both are maximal field tests: motivated, apparently healthy participants give a near-all-out effort over a measured course (track or flat path). They correlate well with directly measured VO2max in fit people (Cooper reported r ≈ 0.90 vs. lab VO2max in Air Force personnel) but require near-maximal exertion — screen first (Pre-Participation Health Screening (Overview)) and not for the unfit/high-risk.
1.5-mile (2.4-km) run test — record the time to complete 1.5 miles (6 laps of a 400-m track).
- VO2max (mL·kg⁻¹·min⁻¹) ≈ 483 / time(min) + 3.5.
Cooper 12-minute run test — record the distance covered in 12 minutes.
- Miles: VO2max ≈ (35.97 × miles) − 11.29
- Kilometres: VO2max ≈ (22.351 × km) − 11.288
- Metres: VO2max ≈ (distance_m − 504.9) / 44.73
Administration tips: warm up; pace evenly (beginners tend to start too fast); allow walking only if necessary; record to the nearest second/measured distance. The 1.5-mile run is favored by military/law-enforcement; the 12-min run is convenient when timing one fixed period.
Key facts
- 1.5-mile run: VO2max = 483 / time(min) + 3.5 (time = minutes to finish).
- Cooper 12-min run: VO2max = (35.97 × miles) − 11.29 (or 22.351×km − 11.288; or (m − 504.9)/44.73).
- Both require maximal effort; correlate ~r 0.90 with lab VO2max in fit subjects.
- Screen out unfit/high-risk individuals; pace evenly.
