sci.running-economy-oxygen-cost Calculator
Calculates running economy (oxygen cost mL/kg/min at a given speed) and estimates VO₂max from race times using the Daniels-Gilbert formula. Running economy 200 mL/kg/km is world-class; 230–250 is recreational — elite marathon runners combine high VO₂max with exceptional running economy.
Inputs
Vo2 Ml Kg Min
Reference formula or conversion factor shown for context.
Speed Km Hr
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Body Mass Kg
Total mass of the body. Used with height to calculate BMI and estimate lean mass.
Results
running economy RE (mL O₂/kg/m)
Sample size or count used in the calculation.
O₂ cost per km (mL O₂/kg/km)
The total monetary cost computed for the given inputs.
absolute VO₂ (L/min)
Sample size or count used in the calculation.
energy cost (kcal/km)
The total monetary cost computed for the given inputs.
RE interpretation
Qualitative summary of what the computed numbers mean in practical terms.
