Evaluating a 12-Minute Performance

A 28-year-old female runner completes a distance of 2,400 meters in her 12-minute Cooper run test.

  1. Step 1: Set Distance = 2,400 meters.
  2. Step 2: Apply the Cooper formula: VO2 Max = (2400 - 504.9) / 44.73.
  3. Step 3: Subtract: 2400 - 504.9 = 1895.1.
  4. Step 4: Divide: 1895.1 / 44.73 ≈ 42.37 mL/kg/min.
  5. Step 5: For a 28-year-old female, 42.4 mL/kg/min is classified as an "Excellent" fitness rating.
