THE EFFECT OF COMPLIANT RUNNING ON KINETICS AND JOINT KINEMATICS

Abstract

This study examined the differences in joint kinematics and kinetics between normal and compliant running, to determine the potential injury prevention benefits and running technique of the latter. Twelve subjects were familiarized with compliant running and completed a full motion analysis while running at a pre-determined, self-selected pace. Distinct differences in both joint kinematics and kinetics were recorded. This was represented by an increase in knee and hip flexion of 52% and 19%, respectively, as well as a decrease in knee and ankle peak extensor/plantar flexor moments of 49% and 43%. Hip flexor moments increased by 54%.
