This seems really hard for me to believe:

What movement exactly are we talking about here?

The use of the wrist as a free hinge.

But we like to meddle don't we?

wrist action

April 4 2012, 5:33 PM 

I didn't read the whole thread but I think I can offer something that might help. Dan Shaguer a Mike Austin student describes the wrist action like this:

Hold your right hand up fingers pointing to the sky. Flap your hand back and forth as fast as you can.

Now take your left hand and grab your right wrist. Make your right wrist go completely limp. Now use your left hand to "shake" your right wrist back and forth.

See how much fast it goes. by being relaxed and letting gravity from the swing release the wrist you will increase your swing speed not inhibit it.

Does this make sense?

Don't see it...

Looking at high speed video I just don't see the trail wrist moving all that fast from 6/100s through impact...

Also depending on your grip and swing mechanics the trail wrist can move in a lot of different ways during that time.

Experiment

April 5 2012, 10:08 PM 

Here is a look at me moving my wrist using muscle power vs. Tiger's wrist movement on a full swing.
[linked image]
It looks to me that my wrist is moving farther in the same amount of time meaning that somebody who is not very fast (me) can flex the wrist using muscle power faster then the wrist flexes in Tiger's swing. What do you think?

Put a club in your hand and then do the check.

The question is whether the muscles can move as fast which they can. This means that activating the muscles can speed the club up.

Activating muscles...

April 6 2012, 2:42 PM 

can only speed the club up if:

o They provide a positive torque and

o If that torque is provided at the proper time

It is impossible to consistently cause a muscle contraction at the right time and, per Jorgensen, the advantage to be gained at the cost of consistency is minimal (because of the mass of the club so it's not just how fast the muscles can move).

bogus experiment

April 6 2012, 12:42 PM 

Tiger's arm is moving and accelerating and
his wrist is releasing relative to a speeding arm.
You are just flapping your wrist. There are other
factors too. Try again.

Bogus comments....

April 6 2012, 2:51 PM 

LOL, my disagreement is with this statement by Peter:
That is an indication that anyone that uses their muscles to move the club in release would be necessarily producing a motion that is slower than it would be with correct (pro) technique.

My experiment shows that the muscles can move plenty fast enough which means that if they were fired at the precisely correct moment then clubhead speed would be increased...

your experiment is interesting my statement comes from a published study. When your work can pass peer review there will be something to discuss.

What the heck are you laughing about?

I guess that my incredibly sophisticated science is probably to difficult for you to understand? That's okay I still consider you my friend anyway!

"HRUMPH...take that, it's settled..." answer to you, so typical and a perfect one liner from him that summarizes his "approach". wink.gif I guess it just struck me as funny in my over tired but yet can't sleep state.

Thats right you do have a new baby in the house. Sleep is hard to come by with a new baby, if I remember correctly?


Good luck with the new baby.
