1.5-Mile Run & Cooper 12-Minute Run Tests

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 (preparticipation-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.

• 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.

• vo2max-overview — where field tests sit among estimation methods.
• rockport-walk-test — lower-intensity alternative for the less fit.
• multistage-shuttle-test — incremental field alternative.
• cardiorespiratory-norms — interpret the resulting VO2max.
• running — modality counterpart.
