Brian Gay Leg Straightening and Newton's Third Law

I posted in the Tour forum: "Why does Brian straighten his legs through impact? I do find this useful in my own swing, but, don't really understand what it is doing for him or me."

Yoda asked me to put this in another thread with the tantalizing statement that the answer is: "Equal and opposite' reaction and its resulting athletic sense."

I am very interested in knowing more about what this means. Such as, what is the force(s)/action(s) it is a reaction to? What does it indicate he has accomplished? What are the feels?

Thank you for any insights that may lift the fog.

seems to happen real early in brians swing

Lots of dudes will straighten their legs AND disrupted the motion of their Right Shoulder. The right shoulder location is HUGE in staying on Plane and being able to trace the Plane Line (or selected Visual Equivalent to the original Plane Line). You can see lots of people who do this early AND goat hump it (hips go toward the plane line and spine gets vertical). . . . this disrupts everything and shoots the arms out to the right and lays the shaft down under plane.

If you'll watch Brian you'll note how well he "keeps his angles" as far as his spine and shoulders go. This is a huge piece of controlling the Angle of Approach (Path) . . . Combine that with excellent controll of the face . . . . You post stats like he did . . . .

Marinate on this a lil' bit . . .

2-H SHOULDER MOTIONS The point may be made that it is impossible to inscribe perfect circles while the center is in motion – that is the turning Shoulder. The straight line requirements of the Compression Point are satisfied as long as both the Vertical and Horizontal Centers move precisely in unison. Direction control remains stable because both Centers are also moving in a circle – that is, the circumference of the Shoulder Turn.

The spine, between the shoulders, is the center of the Shoulder Turn only, not of the Left Arm, except by specific extension of the Swing Radius. Because, Swinging from the Wrists, the Left Shoulder, the Right Elbow, the Waist or the Feet, show it to have just to many exceptions. Though the “Head” Pivot Center is recommended, it is not at all mandatory.

But the Shoulders do have crucial On Plane functions – synchronizing and aligning the Pivot Mtion and Thrust with those of the Power Package (Chapter 6). “On Plane” Right Shoulder Motion is possible only by titling its axis – the spine. See 7-14. In this area the Left Shoulder is helpless. The geometry of Shoulder Control deals only with Right Shoulder, for there are no guide lines for Left Shoulder control of the Right Shoulder. Therefore, variations in Right Shoulder location will vary the Left Shoulder location at Impact and, consequently, the Low Point location as well as the Angle of Approach (2-N).

Being a part of the Pivot and the Power Package, the Right Shoulder must reconcile them by moving with the greatest precision for thrust, speed, direction and distance. (7-3) So the Right Shoulder does not flap around haphazardly – it has many responsibilities. And variations in its Impact location will vary the Right Elbow’s Impact Bend and so may alter the Impact alignment of the Clubface. See 6-E and 7-23. The long Backstroke Shoulder Turn produces CIRCLE Path (10-23-E) and ARC of Approach procedures. The short Shoulder Turn produces “LINE” types of Delivery Path (10-23) and “ANGLE” of Approach procedures (2-J-3). So – if the Shoulder Turn is too great and takes the Hands inside the proper Angle of Approach (2-J-3), then you must shift to an Arc of Approach Delivery Line to “clear the Right Hip” (2-J-3). Or get an unwanted Pull. OR A SHANK. Otherwise, the Three Dimensions will become un-correlated including Compression Leakage (2-C-0) and an obvious struggle. As it goes back, so it tends to come down – because of the differences in Loading Characteristics (Components 11, 19, and 22).

Yah dont stop, Brian. Straighten those things and wear green pants on Sunday at Augusta, they'll work nicely with a green jacket.

Still stewin in your juices 12PB...agree with the bits I understand so far - but what do you reckon to the green stuff I added above...do many angle of approachers really shorten their shoulder turn...or do they use top arc bit....something like that post Yoda did on KJ CHoi about a year ago??

Some of this has to do with Plane Angle as well and the depth of the hands/whether there is a bunch of lifting going on e.g. Furyk . . . . in addition to all that the rate that #4 must release to stay on the selected plane too . . . . and there are probably some assumptions with regards to the "inscribing perfect circles" as mentioned in the first part of 2-H.

Pretty sophistocated subject . . . . probably beyond my level of sophistocation.

"O" no you didn't

Mike O called me and asked if I would post a reply to your above quote (seeing he is retired and all). But I told him that this is a G Rated Forum and we couldn't go there anymore :eyes: .

Yeah . . . . figures that Mikey would get excited about a thread referencing "Gay Leg Straightening" . . . . he's like shotokan 7th degree blackbelt ninja master on that subject.

When there's a full moon up that way holler at Mike for me . . .
