Mathematical Formula & Scientific Methodology

Formula: Locomotor Walking Energy Equation

Calories = Body Weight (kg) × Distance (km) × 0.72 kcal/kg/km

Walking is biomechanically more energy-efficient than running due to inverted pendulum kinetic-to-potential energy transfer, burning ~30% fewer calories per kilometer than running.

Model Assumptions

  • Flat walking surface
