Document Summary
Strength: the application of max. force against an external object. The max. force that can be generated at a given velocity of exercise or movement. Muscle actions where speed is constant throughout are known as isokinetic. Muscle actions where force produced is constant throughout are known as isotonic. I- band: just contains actin (the thin band) Need atp to un-cock this head away from actin a. Need atp to un-cock this head away from actin. Cocking of the myosin head (myosin in high energy form) It takes time to develop max. force for a given motion (dynamic or static) The time to peak force varies with each person and with different movements. Takeoff in spring, actual peak force cannot be achieved because the time to complete these motions is less than the time to reach peak force. It takes about 0. 3-0. 4 seconds to achieve peak force (measured isometrically)
