F. Griffey,
> I disagree with you entirely regarding your statement that for a batter to apply energy built up through torque and transferr of rotational energy, that he [batter] can only do so if he 'KNOWINGLY' applies these forces. Athlete's take direction first and foremost. They are shown a technique, and their talent to train their muscles to execute repetitive form accomplishes them to execute ANY motion offered to them. So, if you are correct, EVERY good batter would have to know (as used in baseball):'force is a result of Kinetic Energy built up either with Linear Momentum or Rotational (Angular)Momentum and torque.' They would have to grasp the concept '(Kinetic)Energy=1/2mv. I don't think so. What makes every athlete good is his bodies ability to retain muscle memory. In combination with muscle memory, it is his knowledge of action reaction that makes him a legend.
Being that the majority of Great Coaches come from outside the academic world, it would then be expected that they use terms like 'staying inside'(which is CHP!)'cracking the whip'(which is 'Torque' around the axis of the wrists. etc. I can see Yogi Berra now....Instead of saying 'get your hips around' -'angularly displace your cartilaginous union of both side of your pelvis anteriority....' C'MON F. Griffy!!!! Unless you are massively built, you can use Linear Mechanics or Rotational, it would'nt matter...if you connect, the ball will travel....futher than UPS or FedEx.... for us 'normally' built guys, Rotational Mechanics are the ONLY solution to increase bat speed. Which is the only variable. The mass(bat) never changes. The only thing you can do is increase the velocity of the bat for a greater POP. What Giambi accomplishes with his arm only, I accomplish with my entire body using Torque and Rotational Mechanics. >

I feel that if torque and rotation were to be used, the batter would need to KNOWINGLY apply these forces... they are not natural movements.

> >
> > So if I am correct in stating that a person must KNOW that they are applying torque and rotation to correctly and most effectively do so, does this mean that the games best hitters (who say that they develop batspeed through different ways) could be much better if they knew that they were applying torque and rotation and tried to apply more over a greater portion of the swing?

I feel that if torque and rotation were to be used, the batter would need to KNOWINGLY apply these forces... they are not natural movements."
> >
> > Your statement seems to imply that torque and rotational energy are just a couple of additional forces a batter can choose to apply to develop bat speed. That is not the case. All bat speed generated, whether from a great or weak hitter, will be derived from the amount of torque and rotational energy applied to the bat. Other than gravity, friction and other more minor factors, "torque" and the "transfer of rotational energy" (via a circular hand-path) are the ONLY forces acting on the bat that causes the bat-head to undergo angular displacement (develop bat speed).
> >
> > I can tell you with absolute certainty that the reason great hitters develop greater bat speed are because their mechanics deliver a greater amount of torque and rotational energy over a greater portion of the swing than do the mechanics of an average hitter. But Mr. Giffrey, I would agree with you, I too, have never heard a single professional hitter say they use torque or rotational energy in their swing.
> >
> > I would also seriously doubt that hitters like Barry Bonds or Gary Sheffield would say they are consciously pulling the bat-head back toward the catcher before they initiate their swing. They would probably discount the importance of applying top-hand-torque and say they are just bringing the hands back to the launch position. But I can assure you that if they stopped the bat-head at the launch position and initiated the swing by pushing the top-hand forward (instead of continuing to pull back), their production would (and has) immediately drop.
> > Would these great hitters be better off if they better understood the mechanics they are using? I would say the answer is a definite yes. First of all, there are few batting coaches who can help them when they're in a slump. Very, very few coaches truly understand the mechanics of a great hitter's swing. They will probably tell the hitter he needs to go back to the basics - which usually means some form of linear mechanics.
