Base of the Neck vs. Through the Head "centers"

[brianmanzella]

Another great answer, Lynn!

But, in case anyone else would like to answer, here is a couple of points to consider about my answer:

If you use the "through the head" pivot center, your swing center—the left shoulder—travels—in a shorter arc on the backstroke.

Also, if you use the "through the head" pivot center, the possiblity for a circle delivery path, becomes far greater than the "base of the neck center."

But, the "through the head" picot center nearly assures the better player that the shoulder turn won't be too flat.

As far as the angles on the pin, I choose to only comment on the thesis of this thread: Is one PERFECTLY still pivot center, TECHNICALLY superior to the other...

...and why?

Inexorably, the adroit betwixt our midst, shall endeavor to formulate a response.

Not being the roundest ball in the golf bag, I will add the following...

If the base of the neck is the stationary point, why would you want or allow a 20 lb plus object (the head) above that center point to have movement?

From the base of the neck (cv7?) is about 4 to 5 inches away from the center point of the head (cv1/2).

Rotation of the head around the spine (you stationary base neck point) does not cause the either center point to move.

Swaying and bobbing would appear to be acceptable product of base of the neck stationary center point UNLESS it is said to be otherwise.

The definition of swaying would be head movement to either side (toward the target or away). I will admit I am having some difficulty with swaying and a stationary neck base center point becuase of the short distance apart, it is more that head leans over with the ear touching the shoulder.

The definition of bobbing would be the up and down motion of the head.

It seems that either of these movements will be disruptive to the golf stroke, be it just impacting balance or causing unnecessary movements to compensate for the location of this 20 plus lb object that is now dancing around.

So is it really acceptable to having the head swaying and bobbing with the base of the neck being the stationary center?

It seems to me that the if the head is only allowed to rotate and is identified as the stationary point, the base of the neck would remain stationary as well. It would just not be the end or top of the rotational axis.

This all assumes the understanding is that if the base of the neck is choosen as the stationary point, then it can not move per-se. But if it can move then in that case it would not comply with 1-L-1/2.

Good points, Marty!

Try this experiment:

Have a pal hold your head dead still.

Have another hold a finger BARELY above the base of the 'neck bone.'

Make a backstroke.

What happens?

The 'neck bone' moves WAY forward.

What is that, reverse swaying?

I don't know what it is exactly, but it is NOT rotation about a fixed point...

'cause the point is MOVING.

Guess I don't know where the neck bone is, cause yes I can feel the outside move, but it is rotating around. At issue is where is the center point and does it move. Is it the 'thoracic spine rotation center'? Now I did your test sitting down, I was attempting to minimize any movement other than the shoulders, don't know if that will make a difference.

The more I read what you write, I guess I am of the opinion that you don't subscribe to 1-L-1/2 cause you keep introducing movements and seem to be supporting your position that even the base of the neck movement is not only permitted but desired.

Oh yeah...

...also notice I cleaned up your work , (much clearer...lol)

Hmmmmm No.....

Your yellow line goes right through Sam's Shoulder Blade...lol

Now, I knew there would be no picture with lines on it that would prove/convince you to you what im about to show you - so I took extreme measures ....lol



Now I don't believe you can argue with this line right ?....

Ok, lets look at the backstroke...



Notice how at address the spine is tilted towards the target and how the spine leans away from the target....

Now look at the photo of snead again beside me....



Is this supposed to be cleaning up my work, or you just not doing your homework ?
