The energetic cost of locomotion does not appear to be tightly linked to the mechanical energy output. The energetic cost of locomotion is more closely linked to the amount and cost of force production. The amount of forced produced during terrestrial locomotion is a function of body weight. Alterations in body weight are expected to alter the amount of force produced and the kinematics of locomotion. If stride frequency or contact time with the ground are reduced, then the cost of locomotion may increase. If the amount of force produced decreases, then the energetic cost of locomotion will be decreased.
