the increased liberation of heat in a stimulated muscle when it is allowed to do mechanical work; the amount of heat liberated is increased in proportion to the distance the muscle is allowed to shorten and in proportion to the tension it must develop (for example, the weight it lifts) during shortening; thus increased chemical energy is consumed both to liberate increased heat and to do increased mechanical work.
