Increasing the step length and decreasing the step frequency at a given speed of walking requires a greater power to lift and accelerate the centre of mass of the body (Ẇ(ext)), whereas decreasing the step length and increasing the step frequency requires a greater power to accelerate the limbs relative to the centre of mass (Ẇ(int)). The sum Ẇ(tot) = Ẇ(ext) + Ẇ(int) reaches a minimum at a step frequency which is 20%-30% less than that freely chosen during walking at that speed. The step frequency at which Ẇ(tot) is minimum increases with speed similarly to the natural step frequency during normal walking.

Abstract

Increasing the step length and decreasing the step frequency at a given speed of walking requires a greater power to lift and accelerate the centre of mass of the body (Ẇ(ext)), whereas decreasing the step length and increasing the step frequency requires a greater power to accelerate the limbs relative to the centre of mass (Ẇ(int)). The sum Ẇ(tot) = Ẇ(ext) + Ẇ(int) reaches a minimum at a step frequency which is 20%-30% less than that freely chosen during walking at that speed. The step frequency at which Ẇ(tot) is minimum increases with speed similarly to the natural step frequency during normal walking.
