He told my wife that he is aware of your program, and has your videos as one of his patients gave to him to look at, but has not watched them all completely. She informed him that I am doing your 724-day program, and that she is doing your pronated swings. He asked her what she was doing to strengthen her shoulder so she can be ready to play ball in the spring. I have her doing your pronated swings like you suggested. I am writing to you in regards to my wife's shoulder.
As a result, the 'traditional' baseball pitching motion violates Newton's law of reaction.Ġ03. Therefore, before they even start applying force to the baseball toward home plate, they completely stop the forward movement of the center of mass of their body from moving toward home plate. Therefore, to continue to move the center of mass of their body forward, their glove leg applies the third force toward home plate.īecause 'traditional' baseball pitchers stride seventy to ninety percent of their standing height, when their glove foot lands, they apply force toward home plate with their glove leg.
During the second part of the acceleration phase, in the same manner as when they are power walking, my baseball pitchers pull back against the ground with their glove foot toward second base. Therefore, to continue to move the center of mass of their body forward, their pitching leg applies the second force toward home plate.Ġ3. During the first part of the acceleration phase, my baseball pitchers push off the pitching rubber with their pitching foot and start to drive the entire pitching arm side of their body toward home plate. Therefore, to start to move the center of mass of their body forward, their glove leg applies the first force toward second base.Ġ2. During the pendulum swing of their pitching arm, my baseball pitchers push off ground behind the pitching rubber with their glove foot and step straight forward toward home plate. In my Drop Out Wind-Up competitive baseball pitching motion, my baseball pitchers stand with their pitching foot on the pitching rubber and their glove foot one step behind the pitching rubber.Ġ1. The reason for this request is that too many coaches misrepresent you on these 2 mechanics.Įven though, in compliance with Newton's law of reaction, the glove arm also applies force toward second base, in this discussion, I will explain only how the legs provide force toward second base. To avoid any more confusion and to set the record straight, please explain the force toward 2nd base for the glove leg and pitching leg. Well, you certainly explained the difference between Newton's third law and force-coupling, that was well received on my end. If readers watch the side view high-speed film of my baseball pitchers, then they will see that, as they extend their pitching elbow through release, the tip of their pitching elbow comes to a complete stop.īecause my baseball pitchers apply force toward straight toward second base with their glove arm, pitching leg and glove leg, they maximize Newton's Law of Reaction. That means that their pitching upper arm applies force toward second base concurrent with their pitching forearm applying force toward home plate. In the drive through release second part of the Acceleration Phase of my baseball pitching motion, my baseball pitchers apply oppositely-directed forces on either side of their pitching elbow. Sir Isaac Newton's third law of motion, the Law of Reaction, says For every action force, there is an equal and oppositely-directed reaction force.įorce-coupling occurs when athletes apply oppositely-directed forces on both sides of a fulcrum. You are confusing Newton's Law of Reaction and force-coupling. Does not the rest of the body have to be covered by Newton 3rd law also? In others words, every movement by the body forward has to have a opposite movement backward, front arm and stride foot included. With the pitching arm fully covered by your explanations, I want to wrap up this subject with this question. On Sunday, January 03, 2010, I posted the following questions and answers.
