Abstract
WHEN muscular force is exerted, power is expended and fatigue is produced, even when the muscle remains stationary. Again, when no external force opposes the contraction of the muscle, physiological causes set a limit to the speed at which contraction can take place. In both cases the whole power expended is lost in so far as the production of useful work is concerned. When there is no velocity the power is used in maintaining the stress, and when there is no resistance, in maintaining a constant velocity.1
