What Is VO2 Max and Why Does It Matter?
VO2 max measures the maximum rate of oxygen consumption (in milliliters of oxygen per kilogram of body weight per minute, mL/kg/min) achievable during maximal cardiovascular exertion. It reflects the integrated efficiency of your lungs, heart, vascular network, and skeletal muscle mitochondria.
George et al. 1.5-Mile Clinical Run Formula
VO₂ Max=88.02−(0.1656 × Wkg)−(2.76 × Timemin)+(3.716 × Sex(M:1, F:0))
Step-by-Step Calculation Breakdown (35yo Male, 170 lbs, 11:30 1.5-Mile)Step 1: Convert Units to Metric Weights and Decimal MinutesWeight = 170 lbs ÷ 2.20462 = 77.11 kg
11 minutes 30 seconds = 11 + (30 ÷ 60) = 11.50 minutes
Step 2: Calculate Formula Regression CoefficientsWeight Deduction = 0.1656 × 77.11 kg = 12.77
Time Deduction = 2.76 × 11.50 min = 31.74
Sex Factor (Male) = +3.716
Step 3: Combine Factors for Final Aerobic CapacityVO₂ Max=47.2 mL/kg/min (Good / Top 25% Category)
