Bio Mechanics

Hold on though . . . Y'all may not have said it . . . but I'm saying it . . . I'M SAYING HE'S EFFICIENT FOR THE TASK AT HAND . . . Hit it really far. So that came out of my world not y'all's . . . to me anyway the question then becomes . . . if these cats hit the ball far and we can just discount what they are doing whacky with their arms (which is a piece of it for them) . . . what are they doing with their pivot?

If there was a way to look at Hogan's pivot and JS's pivot . . . you'd see some definite similarities . . .

I see the similarities between JS and a young John Daly (JD).
JD should have had a lot more victories if he was able to control his lifestyle.

Driver pivot ain't necessarily just about physics . . . also about pivoting in fashion to achieve the required launch conditions to hit far via angle of attack, angle of approach and how fast you "get it outta the ground".

David, Brian Gay has worked with these guys and been measured many times I believe(?). Bio said earlier in the thread that Brian worked with them for many years before LB, he has both helped and been helped by biomechanics it would seem. Don't know about Huff and Fort. I'm sure Yoda would be into the ideas found in at least Bio's approach to biomechanics (as has been stated there are many suspect approaches out there). It doesn't go against any of his (excellent) teachings, only adds to them. Worth reading Bio's recent post on the swing-pattern thread.
You are right about the longevity of some too, so many injuries from movement patterns, you still can play great golf like that but the cost is in pain.

Bucket,

Why be such a tight ass?

The TPI web site has lots of information on the evaluation and recommended exercises. Using this as a base and googling some of the terms I came up with most of what I wanted. I have worked with PT's for cervical stenosis with neuropathy, lumbar stenosis with neuropathy and with proper exercises avoided surgery. These were were not related to any of my golfing endeavors. Doing fitness exercises, practicing and playing is diffcult for my body and my associated arthritis. However i have resumed working with a fitness trainer and she is tuned in already to many of these. I would add that Bio mentions evaluation to determine one's specific needs. I would add that I think everyone should have a diagnostic PT exam. A good PT can pin point areas of weakness even in those that work out a lot. Most folks have some assymetrical issues going on. I had compensatory muscles doing things my hip knee and abs should have been doing. So I think biomechanics is very valid. I would like to see it integrated into TGM so that more intelligent choices can be made about certain patterns. So far my experience with Lynn has not conflicted with my PT's advise about avoidance of further injury and so far I have no recurrence
How about a straight line delivery exercise, a catch the dog by the tail exercise, left forearm takeaway exercise perhaps with a medicine ball, stretch bands. I could see perhaps a startdown, sit down drill with a belt around the waist(hips) attached to exercise bands and another one attached from the hands to the ceiling etc. How about a Wi Fit program that measures the weight shift during the backswing and integrating it into the Wi golf game to show length of drives etc.

Nice one! That was for Mikey!

Bioengine,

Question:

I'm really curious and you probably know the answer.

Lets say a Golfer weighs 180 lbs.

1. What is the typical MAXIMUM ground pressure he creates during the swing?
   
2. Approximately when in the Downstroke does this occur?

Daryl,
Here is the mis conception about pressure plates. Weight has nothing to do with pressure plates.
Allow me to explain.
You have two forces normal force , which is your force going into the ground,This is your centre of mass (weight).

Then you have shear forces working along the surface of the ground. Left foot forces, one is away from your left towards the target.the second is away from your toes.
Right foot one force is away from the right foot,away from the target and the second is from your right heal.

It's all about how your press into your left side to create ground reaction forces.The ability to press into your left side and foot and how well you do this is what creates an equal and opposite force reaction. The equal and opposite force reaction creates lower body stabilization and creates hip rotation cause your hips to turn left. The continuation of pressing in to your left side and also create stabilizing at impact and create hip deceleration. This allows your upper body to close.

Predominately during the back swing good players with good lower body mechanics,centre of mass starts to press into their left side during their backswing.

It's not about transfering weight this is a myth. It's your centre of mass moving into your left side and the ability to press into your left side.
When people see pressure plate data and see pressure is moving to the left side they mistake this these forces being their weight.
Not weight it's forces.
So what happens every tries to transfer the weight. Not good.

To achieve this your have to train your body how to create ground forces. We have done researching trying to physically trying to do it and we can't make it happen.

[O.B.Left]

Left , Right, Left, Right. Im going to ground force my way into the kitchen and get me another Molson.

Dont take this the wrong way though Bio. I do agree, basic though it is, it is the basis of golf motion. You cant pivot around a non loaded leg. Gotta get off the back foot. Dont hang back. Post up. Hit against a Firm left side etc etc.

Left, right, left , right , left , right

Good stuff here . . . . Very nice . . . . now the question is how and how much . . . Does the shoulder tilt have anything to do with how much you press forward?

Good post . . . comentary on the pics is welcome.





Check the left knee in this sequence . . .



He didn't do it anything like he demonstrated . . . check the tilt in the shoulders . . . if he actually did this you'da never heard of him . . . course maybe that's what he did before the secret? Compare the shoulders in the pics above this . . . WAY DIFFERENT.



Maybe one of the best Hogan pics I've seen . . . AWESOME. Check out the #3 angle and the clubface . . . BEAUTIFUL!!!!
