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.

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!!!!
