Yes, that would be nice to have, Jack. But you're talking about the subject of a master's thesis, if not a Ph.D. What you're asking for would fill the pages of this website several times, if done thoroughly. The original question was in regards to the definition of the kinetic chain. My posting was a response to that.

I do beleive that the kinetic chain is a what passes the energy through the stationary axis of rotation, and with the proper manipulation of the bat (top/ bottom hand torque) results in batspeed. The bottom line is that the kinetic chain helps a hitter understand how energy moves through the body, but it must be understood that the kinetic chain only works when the hitter is relaxed and not paying attention to it. I feel that the kinetic chain also explains why after the initiation of rotation that the swing is basically on autopilot. ( the hips rotate hard and then the swing is on its own. ) The idea of the kinetic chain provided me with peace of mind and some explanation of the movement of energy but serves little or no practical purpose in learning the proper motor functions to master the swing. People should be more focused on mastering top hand torque,focus , and reaching their top batspeed... then worrying about things they cant control. : james, i think that for the most part you are right ...you don't step up to the plate with science on your mind...but i still yhink that it's fun, interesting and not at all unproductive to search for the PERFECT SWING.....grc....
