Can the right wrist be bent and cocked?
 
Can the right wrist be bent and cocked? Or bent and uncocked? I never see these terms being used.

On some more thinking, with a slightly bent right wrist its actually pretty easy.

But when I bend my wrist to the maximum I feel like it isn't possible to cock and uncock with that maximum amount of bend, is this true?

It is true that if one bends the wrist excessively (either palmar flexion or dorsiflexion) that it will markedly limit the amount of cocking simultaneously possible, and the reason is that the two movements both involve the radio-carpal joint, and ulnar/radial directional movements at that joint will be limited when the radio-carpal joint is not in a neutral position (especially if the joint is dorsiflexed - bent backwards).

I wonder .. what is a cock .. and what is a bend?... A wrist can be rotated 360 degrees...

can it be bent and cocked at the same time and be called a bent?...

I always wanted to ask this question as well.

Hmm?

The Right Wrist should not be Cocked. The Right Forearm and Clubshaft should maintain the same relationship throughout the swing. The amount of Right Wrist Bend at impact is determined by Right Elbow Location at impact (all other things being equal). The Right Elbow Cocks the Left Wrist.

The fingers of the Right Hand should grip the Clubshaft. If the Right Hand Grip mirrors the Left Hand Grip (Palm type Grip), then the Right Wrist will cock. If you use the fingers of the Right Hand to Grip the Club, the the Right Wrist can be independent of the Left Wrist Cocking motion and the Right Wrist can remain Level throughout the Swing.
However if you prefer to cock the Right Wrist, it can be done in a number of ways. One of my personal favorites goes like this: Get into impact fix position with a Bent Right Wrist. Now, rotate your Right Forearm counterclockwise. Now you have a Bent and Cocked Right Wrist.

If you could sit on the Clubshaft during a swing (if you were 1" high and I Duct Taped you to the grip) and looked only at the Left Arm, you would Think that Uncocking is a pretty significant motion. But if you only looked at the Right Wrist, you wouldn't see or feel any other motion at all except that during release you would move farther away from the Right Shoulder. Put the Right Hand and Wrist and Forearm in a cast.

99.99% of all Golfers think that the Uncocking Left Wrist increases the Velocity of the Clubhead. Hmm? :)

Thumbkin
 
when you say that the club is gripped in the fingers of the right hand you are not referring to the left hand thumb fitting into the right palm, right? My main focus is to make sure that thumbkin and the palm are one, as in # 1 pressure point, as if the left thumb was a trusty dowel! Hogan focused on the middle fingers of the right hand...but it seems as if the thumb/palm relationship is where it is at. I swing on most shots...but I still like to feel # 1 when I take my grip...would that send a switting signal? :(

Right Palm covers Left Thumb. Right Fingers Grip Clubshaft. Look in the Hogan Book.

the wrist bends and cocks invariably to some degree

-----------------------------------------

I cannot really understand your question. Surely, the term "cocking" refers to either ulnar deviation (downcocking) or radial deviation (upcocking) of the wrist, while "bending" refers to dorsiflexion (back-hinging) of the wrist. It is obviously possible to first either radially deviate, or ulnarly deviate, the wrist prior to bending the wrist back. In both situations, the wrist will be bent backwards, but it will also be either radially deviated or ulnarly deviated in its bent position.

I personally do not believe the wrist can rotate 360 degrees due to movements within the wrist joint. I believe that the hand can rotate 360 degrees, and that the hand rotational movement is due to a forearm rotational movement and not a wrist rotational movement.

Jeff.

Maybe we can look at this another way. What if Left Wrist Cocking was any Vertical (in-line with the left arm) motion of the left wrist produced by bending of the right elbow? So, as long as the Cocking is a vertical motion, then it doesn't matter what the wrist looks like.

I think so.

Ok .... how does this work then? You seem to know Something !

Where is the Machine in the flesh?..

Thanks

It doesn't?....its after all an accumulator.

tbyeaton0627 05-21-2008 09:11 AM

The feeling is to not cock the right wrist and one should never attempt to purposely cock the right wrist, however we as human beings are not machines and 3-D machines show that even the the best of players may have wrist deviations of at least 10 degrees...which is almost impossible to see with the human eye especially in 3 dimensions

If the Right Wrist remains Level and Bent from Top to both arms Straight, then the Right Hand moves at the same RPM and Speed as the Clubshaft. Clubhead Velocity is greater due to Right Hand Roll and Lever Extension.

How much bend is the question, the degree to which of right wrist bend is constantly changing, losing the bend creates speed, bend hits it with a longer radius

Bend has nothing to do with it. Level is the relationship of the Longitudinal Angle between the Clubshaft and Right Forearm. Bent is the Radial Relationship (Flying Wedge).

Does change? Should Change? Must Change?

tbyeaton0627 05-21-2008 10:23 AM

All of the above

losing the bend changes the center, losing the bend faster creates greater speed but changes the length, hitting it with a smaller radius

Thanks,,,so whats is the average ? deviation and how much you think Tiger Wood deviates?.. You got this from TPI, iclub ? very interesting..
