>>> Without arguing for any particular side here and only in an attempt to keep the definitions straight in the interests of clarity, I don't think you guys know what bow arch refers to. And scap loading is about as far away as you can get from linear teaching. Polar opposite actually. If you don't think MLB hitters display scapular adduction and abduction that's fine, but at least know what you are disagreeing with. :) <<<

Hi

I agree, it is important “to keep the definitions straight in the interests of clarity.” In fact, without a clear definition of a mechanic, it is impossible to have a constructive debate regarding its contribution to the swing. I think a discussion of “scap loading” and “bow arch” could be enlightening to all if we are given a clear definition of (1) What is its purpose – Is it a cue or a mechanic? – Is it to prepare a good launch position, or is it a transfer mechanic? (2) How does it impact the development of bat speed? (3) What forces does it apply to the bat that generates bat-head acceleration?

Once we have these points defined, we can then have a constructive debate. However, I have read pages explaining all the muscles, fibers and bones involved in “scap loading” without once mentioning the bat - much less the forces it applies to it. Remember that the ultimate purpose of all swing mechanics is to accelerate the bat-head around to contact. Until we understand how a mechanic accelerates shoulder or bat-head rotation, it is useless to discuss the muscles involved..

I look forward to your definitions of “scap loading” and “bow arch.”
