Quantifying mechanical and metabolic interdependence between speed and propulsive force during walking.

ABSTRACT: Walking speed is a useful surrogate for health status across the population. Walking speed appears to be governed in part by interlimb coordination between propulsive (F_P) and braking (F_B) forces generated during step-to-step transitions and is simultaneously optimized to minimize metabolic cost. Of those forces, F_P generated during push-off has received significantly more attention as a contributor to walking performance. Our goal was to first establish empirical relations between F_P and walking speed and then to quantify their effects on metabolic cost in young adults. To specifically address any link between F_P and walking speed, we used a self-paced treadmill controller and real-time biofeedback to independently prescribe walking s
