The mechanical action of the levers employed determines the power which the muscle must exert to perform the work. Two factors influence the amount of power which a muscle can supply to its lever: variation in the strength of the pull resulting from different degrees of stretch of the working muscles and the mechanical advantage of the lever. The position of a muscle at contraction affects the strength of the pull of the muscle. The position of greatest pull is one in which the muscle is slightly stretched.
