During running, the mechanical energy of the centre of mass of the body (COM) oscillates throughout the step like a spring-mass system , where part of its mechanical energy is stored during negative phases to be released during the following positive phases. This storage-release of energy improves muscle-tendon efficiency, which is related to lower...
