Cooper's 12-minute run test assesses which aspects of fitness?

• A. Tests muscular strength in the hand
• B. Tests cardiovascular fitness and muscular endurance in legs
• C. Tests flexibility of the hamstrings
• D. Tests speed and agility

Answer: (B)

Cooper's 12-minute run is all about sustaining activity for a period of time, so it mainly tests aerobic endurance and the ability of the leg muscles to keep working over an extended effort. While you’re running, the heart and lungs must supply enough oxygen to the working leg muscles, reflecting cardiovascular fitness. Because the test requires continuous running for 12 minutes, the leg muscles’ endurance to repeat contractions without tiring is also being assessed. It doesn’t measure hand strength, flexibility, or speed and agility, which require different tests.
