How oxygen support can elevate your aerobic performance
🧬 What Is VO2 Max?
VO2 max is the maximum volume of oxygen your body can use during exercise, measured in millilitres per minute per kilogram of body weight (ml/kg/min). The higher the number, the more oxygen your body can deliver to working muscles — and the better your endurance potential.
🧮 How to Estimate VO2 Max: Online Calculator or Field Test
✅ Simple VO2 Max Formula (Using Run Time):
VO2 Max = (Distance in metres – 504.9) ÷ 44.73
Example: If you run 1.5 miles (2,414m) in 12 minutes:
(2414 – 504.9) ÷ 44.73 ≈ 42.7 ml/kg/min
✅ Using Resting Heart Rate:
VO2 Max ≈ 15 × (HRmax ÷ HRrest)
This is less precise, but gives a general estimate.
