>>> a lot of people assume that since the lower body muscles (e.g., hips)are the larger & stronger muscles, these muscles contribute the most towards the hitter's power.....i have heard some speculate that the ratio of contribution is as much as 90-10 (lower being the 90)......

> taking an outside pitch as an example(and PLEASE, let's forget about lineare vs. rotation for a moment), a major league hitter can, with perhaps 45 degrees or so of hip & shoulder rotation hit the ball to the opposite field about 370+ feet.....and this is fact, evidenced by what i have seen).....but a major leaguer, with full hip & shoulder rotation (90 degrees+)can pull an inside pitch 425+ feet....extrapolating from this one could conclude that 90 degree hip & shoulder rotation adds aprox. 15 percent to the distance of the ball that is hit with only 45 degree hip & shoulder rotation.....
> my point?....yes, i know the shoulders will not be glued to the wall, and i know there are other factors, BUT......the point is that there seems like a lot more potential power in the upper body (INCLUDING THE ARMS)than some people realize.....
> and could it be that major leaguers themselves realize this?....certainly in their conditioning programs they do lower body work but they do plenty of upper body work as well (e.g., biceps, triceps, forearms).....
> respectfully, grc.....

I can't tell you exactly how much power the arms produce, thats beyond my knowledge. But you also have to consider that not all major leaguers are experts on the swing. This question is really making me think i'll write back on this tomorrow
