Does the Spine Angle stay the same throughout the entire motion of a Full Stroke ?

[annikan skywalker]

Great effort Yipped....We'll go through it slowly

The Pelvis is rotated forward at address...with flexion at both hips and a very slight extension of the tailbone and lower portion of the lumbar....With minimal to no lateral flexion and rotation due to a squared away body alignment at address...

In the backstroke..the pelvis rotates clockwise with internal rotation at the right hip and external rotation at the left hip depending on the pivot style (slide versus shiftless) would determine the amount of lateral flexion at each hip joint thus affecting greatly the hip slant...Note: also the amount of backstoke hip slide and/or change in leg action would also cause a slight abduction at the left hip with perhaps a very slight increase in flexion ans a slight adduction and slight movement toward extension in the right hip joint

Downstroke the pelvis is rotating counter-clockwise and the opposite motions and rotation at each hip joint will take place and also moving with some degree of translation due to hip slide thus causing an overall Axis Tilt...to set in..

During the Follow Through and Finsh there is both the continual rotation counter-clockwise of the pelvis and internal rotation at the left hip and some internal rotation at the right hip at and extension of the pelvis and both of the hip joints resulting from the degree of hip slide caused by translation all causing the Torso to move up and back toward a neutral alignment for the Finish....

woah...that's just a very basic description of the pelvis....

Thanks, I think I can imagine what an in depth description looks like!.

Following up to <<Now take all 4 sections and move in these here directions?>>

How is that done or is it a result?

Appreciate your efforts on this challenging subject.

EDIT:

OK. Missed your last post.

OK... Maybe we can break these items down one at a time. The neutral position of the pelvis is about 30 degrees. "The Pelvis is rotated forward at address." (1)Is the pelvis still neutral at address? (2) Does the pelvis vary from this neutral position throughout the stroke, and if so when and how much?

Great question Lagster......depends on factors such as body build and ball flight preference


Tip du Jour...More pelvic angle for a cut shot that start to the left of the stance line than that of a draw that starts to the right of the stance line!!!

.................................................. ..

Some some Pelvic Angle factors--

1. Height of player
2. Length of legs, arms, torso of player
3. Genetics-- flexibility, muscle development, etc.
4. Gender
5. Age
6. Ball flight preference
7.
8.

Should I direct any attention to the knees?

The Foot and Knee action influence the Hip Action so have a huge effect on how not only the Sacral and Lumbar spine moves, but the whole Spine.

Yoda I believe did mention on another thread how the driving knee action of his past swing pattern and other contemporaries of that time put considerable stress on the back. What should the action of the feet and knees be to influence proper hip motion and be kinder to the back and spine?

[yippedagain]

Yoda is not alone. Leg driving in the Downswing was THE WAY back in the seventies.
Dr Jim Suttie maintains 80% of all golfers incur back problems at some time in their career, and that hospital beds are full of leg drivers!.
I think it depends on how much you want to protect your back.
"Good golfer = Bad Back" - Roberto De Vicenzo. Seems to go with the territory.
A stress free back during the Golf Swing would mean standing more erect and turning the Pivot Components back and through together. Lagless.
Would have obvious disadvantages.
