Bioengine,
I cannot speak for V.J. Trolio, but I do not think that
he ever insinuated that he descovered Rooting. Hd did
mention that Rooting was a martial art tecnique. Martial
Arts was in play long before Golf was invented.
I sence that the disagreement is when the center of mass
moves to the left. Your posts appear to indicated that
there is a gradual move to the left from the top of the
backswing. In Hogan's case the complete move was completed
prior to starting the downswing. Trlio did not say that
this was the way that it should or has to be done, but
the way that Hogan did it. A gradual shift of the center
of mass in the downswing followed by a hip turn is very difficult to execute.
Dkerby,
I hadn't elaborated when people start pressing forward occurs.
I didn't agree how he described the shear forces created hip rotational speed. Ground reaction forces create hip rotational torque and supper stiffen. This information wasn't quite right by trolio, he's on the right track although it's important if people are to learn about ground forces the information has to be accurate.
Trolio is selling videos and making money off someone else's research and hard work, this is true. Maybe he's not saying it's his work although they way he promotes his video comes across that way.
This is why I said I hope he has the common decency to give a kick back to the person he got his information from. Sorry if I offended anyone by saying this, although I feel it's just the right thing to do. If someone took one of Yoda's ideas and put it on video and sold it I would say the same thing.
I do agree with Trolio that hogan started pressing forward prior to completing his back swing.Although the move wasn't completed before the downswing started.
Super stiffen or rooting occurs just prior to impact and sustains until impact occurs. This happen so fast you can't see it nor on video can pick this up.
The hips actually counter torque and turn back away from the target a few degrees when you super stiffen . On video you won't see this occur. When the upper body catches up with the hips and impact occurs, the hips and upper body turn through to a full finish together.
People who have good ground forces and lower body mechanics they all start pressing forward prior completion of the backswing.
This is why I have said all along, you can't physically apply ground forces or this move on the practice fairway.
You need to train your body how to create this movement pattern.

Daryl,
In the first photo, the white is normal forces.
Yellow arrows are shear forces.
Orange is the ground reaction forces.
The black line is the direction of pressure or force.
From the photo's take notice all the way into impact how stable hogans left side is, barely moves. Hogan has an internal hip rotation.
Notice through out the swing hogans hips and shoulders are perpendicular to his spine.
In the last photo notice his hips and shoulders are square to each others. Hogan's hips and shoulder are perpendicular to his spine.
Hogan's knew how to create ground forces and super stiffen at impact (stabilize). This allowed hogan to fire his upper body and square up with his hips at impact.
Poetry in motion.

I have two slow motion videos; of Brian Gay and Greg Norman where the hips actually counter torque and turn back away from the target a few degrees before Impact. So, it's possible to witness this event on Video. I'll find them and put them up for everyone's review.

This would be great to see if you have these videos, looking forward to seeing them, with stock standard cameras you can't pick this up when you slow them down. If your breaking down a golf swing frame by frame in slow motion, supper stiffen is something you miss. Super stiffen and impact can occur between frames.
Depends on what people class as impact. I'm talking about when the ball and clubs very first contact when to ball and impact initially come in contact, or exactly moment super stiffen occurs.
Do you know what frames per second between 5000 to 10000 frames per second? Must have been captured by some very high tech gear. Or extremely lucky it occurred in sequence to frames. A very rear occasion.

Bioengine,
Early 90's to 96 your crew worked with Greg Norman?
Sources say your crew was responsible for dramatic changes to Norman's swing in the early 90's?
In 1995 there is a article about Brian Gay working with your crew.According to sources Brian work with you crew for years.
Does Brian still get tested ?

MPS1,
You have reliable sources for providing accurate information is all I can say, I'm not able to comment much further due to client privacy agreements.
Again even thought the team has worked with Brian in the past. Again I can't comment on Brian any further.
