I have a gap in my understanding of the swing, and would appreciate some education.

> I am aware that many of the greatest power hitters of all time were not large of stature. The facts (as I understand them) are that 200lbs was an abberation, and that bat weight was mid-to-high 30s, w/ Ruth and others being in the 40s.
>
> Today's players are much stronger, pursuing weight training and nutritional programs undreamed of in the past. It seems pretty clear some of them are pursuing shortcuts to gaining the muscle mass as well, but whatever - the fact is, today's power hitters have 30-50 lbs more muscle than in the past.

> Depending on which old timer's apochraphal story you listen to, guys like Mantle hit balls 600' or 800' or 3000'. Silly, probably, but the point is they did hit some tape measure shots, and if they could have stood 6" off the plate w/ impugnity like Bonds, 73 might not have set the record.

> 2) If there is a correlation between strength and bat speed, which muscles are most important to strengthen? (I assume predominantly lower body, with upper body development being more of a "look good on the trading card" phenomenon. But, I know I could well be wrong on this.)
>
> 3) If there is no direct correlation between strength and bat speed, is it possible that enhanced strength helps just in the sense of being able to swing w/ minimal fatigue and near maximal energy each day and each at-bat?
>
> 4) How did batters of previous eras do what they did? Was the extra weight in the bat a bigger factor than perhaps is commonly allowed? (I'm sure the answer to this is in Adair's book, and I intend to read it, but I wouldn't mind a shortcut in the meantime).

>.........We just battled this issue indirectly on another site. I believe some players can transfer momentum through the chain very efficiently and maintain bat acceleration. Acceleration is more important than speed. It reduces timing error too. The ability to coordinate the transfer of energy from hips to torso to shoulders to arms to wrist/hands is paramount. It probably separates good from great. It is also hard to see and measure. Ever seen a big muscular guy shoot a fade away jumper from the 3 pt. line...... or consistently out drive Tiger Woods........you won't. Quickness and fast twitch muscle fibers are probably more common in moderate size guys and might facilitate this transfer???
