The basics of how a muscle generates power are this: Filaments of myosin tugging on filaments of actin shorten, or contract, the muscle. Since the 1950s physiologists have had a formula – the length-tension curve – that accurately describes the force a muscle exerts at all points from fully outstretched, when every weight lifter knows there is little strength, to the middle points that display the greatest force, to the completely shortened muscle when, again, strength is minimized. The assumption for 50 years has been that the power comes primarily from what's happening straight up and down the length of the muscle. read more
