>>> He(Adair) states in his book that the body moves forward about 18 inches at 7 mph during the swing. (not before rotation, but during the swing).

In a paper I sent him, I stated that batters might stride forward as they prepare to swing. However, their forward motion ceased before rotation and they rotated around a stationary axis. He stated that was impossible. For a batter to develop the needed kinetic energy for the swing there must be forward movement of body mass during the swing. He then went on to state in a letter to me that any batter who rotated around stationary axis could not generate enough energy to hit a ball past second base.

You can agrue if this translation move provides more energy, but you can't deny it works. It does work, but you must stay coiled during the translation move (not swinging) and then uncoil at the end of the stride (swing).

You are not swinging during weight shift or the translation movement, you swing at the end of the movement (become rotational). You can lump the weight and translation movement into the loading portion of the swing (some might call it coiling). Just like someone might load without a translation movement. the translation movement becomes part of the loading and unloading cycle. It's just a different way of creating energy for the swing.

When in reality it works just as well, just fewer hitters have a pronounced weight shift (mass moving forward), and even fewer right handers have such a move. You see it in lefty's moreso then righties.

> > > > > > > > > > > Your not a linear hitter because of your weight shift or translation move, which can be called a linear move, you are linear because of your transfer mechanics (not being rotational at the end of the stride). I think this site has debated this issue many times about the definition of linear and rotational. What is being overlooked is the fact the real swing doesn't begin until toe touch (heel drop). You can still be a rotational hitter, however we want to define rotation. But' by the definitions used at this site rotational vs linear has to so with transfer mechanics.

If you think the swing starts at heel drop you'll be late against top fastballs. Or, you'll be starting early and subject to poor results against offspeed pitches. The hips push the heel down. The heel drop does not initiate the swing.

I guess you don't like Epstein's teaching on the subject. I don't agree with the heel drop initiating the swing either, it's just a reference point to the unloading of the swing.

Any slower launch and you're late. Any unnecessary movements of the arms and you're in trouble. If you have to drop your heel to launch the hip you're late. Plain and simiple.

Ideally we to understand both sides of the story. They both apply to swinging a bat and hitting. Ted also said everybody lunges somewhat, this applies to being early. You can't shoot a canon from a canoe, if the that front foot doesn't get down your in trouble (and this can happens for varies reasons, e.g. striding and swinging).

Hi Barry,

It seems as this post has illicited a vast array of responses, all which might seem, upon a primary glance, to hold validity. For instance, is it de facto to shift weight onto the front foot as a means of developing power for bat-speed?

When phrased in this manner, the only a yes / no response can satisfy the equation. If the question pertains to whether or not a person must shift his or her weight towards the anterior or posterior foot in the stance, one must affirm that weight shift is necessary, since it helps bring the batter to a balanced posture. However, if the question asks whether weight shift continues once the batter sets up the proper axis, the question, affirmed in the former instance, must be repudiated in the latter instance. Hence, Jack Mankin is correct in his argument that weight shift and rotation are not concomitant with each other.

Mike Epstein argues that, once the front heel drops, and the front shoulder tucks, rotation begins. Put bluntly, the body, once lunging ahead with the bat, now must follow a path around the rotating body. In fact, JJA, in one post, argued that, no matter how hard a person tries to push the hands linearly, they will always wind up gyrating in a circular pattern, providing the lower body rotates around a stationary axis. This is why the front heel drop is essential, for, without it, no hip rotation would be initiated, and the resulting swing would be all upper body.

Epstein and Mankin also recognize that "kinetic energy works from the ground up," which is why I believe that Epstein's torque position is instrumental in accumulating bat speed. In short, here's what occurs:

1) A person lands with his / her front toe opened 45-90 degrees.
2) That individual must drop the front heel.
3) At the same time, that person must bring the back heel off the ground, turn the back knee down and in, and bring the back hip around its axis.

As for as upper body mechanics are concerned, I believe that all good hitters have a CHP, but have yet to decide whether torque is a factor, or just a cue. I say this, not because I find Paul Nyman's arguments persuasive, but because I wonder how a person can torque a bat if centrifugal force will cause the bat to become light at contact anyway. My alternative theory is that the bat either traverses a greater degree of rotation, or has sweeps through a wider circumference.

Lastly, I have not knowledge of kinesiology, since my bailiwick is in English and Euclidean Geometry. To find that out, I would ask Tom Guerry.

I hope I "covered all the bases."

Take care,
BHL
