Running in a mammal, such as a human, is augmented by adaptively modulating anticipation of maximum leg extension of a mammal when running, and actuating an exoskeletal clutch linked in series to at least one elastic element, wherein the clutch and elastic element form an exoskeleton and are attached in parallel to at least one muscle-tendon unit of a leg of the mammal and span at least one joint of the mammal fitted with the exoskeleton. The exoskeletal clutch is actuated in advance of a predicted maximum extension of the exoskeletal clutch to thereby cause the exoskeletal clutch to lock essentially simultaneously with ground strike by the leg of the mammal. The elastic element is thereby engaged during stance phase of the gait of the mammal while running, and subsequently is disengaged prior to or during the swing phase of the gait of the mammal, thereby augmenting running of the mammal.
