|To gain the best response from a muscle or muscle group, the muscle should be put on stretch. For example, throwing a ball at high velocity requires the pitcher to reach back with the throwing arm while stepping forward with his leading leg to put the muscles into full stretch. The elasticity of the muscle when positioned near full stretch helps initiate movement. This is known as the "stretch reflex."|
I bring it to our attention to add to the discussion on Inside Leg Extension, Independent Leg Steering, and so on. The passage goes on to say,
|Muscles can develop more force in a concentric motion (forward) if they are first worked eccentrically (away). For example, a person is given two trials to make a maximum jump vertically. In the first trial, the person squats 90 degrees at the knee joint and leaps into the air. On trial two, the same person stands vertically, then drops to the same 90 degree knee position, then rebounds vertically to jump even higher. The eccentric stretch caused by trying to halt the downward movement makes the upward movement even stronger. This is another example of the stretch reflex..."|
Any thoughts on this?
