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

[yippedagain]

Hitting as many shots left handed as right handed, or vice versa, would also prevent injury. If you have a lot of time of course.

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....

OK... there's the very BASIC DESCRIPTION of the Sacral Motion during a golf motion. How about moving UP to the Lumbar Spine?

//////////////////////////////////////////////////////////////

How about the LOWER BACK? How much Lordonic Curve should one have at Address? Does it stay the same throughout the Stroke?

[annikan skywalker]

How much Lordodic Curve one should have varies from individual to individual...That's like saying everyone in the world fits into a 34 waist and 32 inseam....

The Lumbar Spine is flexed forward as a result of the flexion at the hips...some extension at the lumbar produces the lordodic curve you speak of...again this varies individual to individual...

Throughout the swing the changes in the lumbar spine are very slight with the major changes occurring during the rise through Impact, Follow-Through and Finsih..moving from Flexion to Extension....





The Thoracic Spine changes are subject to individual posture differences...Some have a flatter upper spine due to the cervical spine remaining closer to neutral...while others who have more flexion at the neck this causes more protrusion of the thoracic spine..making it more of a rounded look....These players experience more changes throuhgout the stroke.....

[Homerson]

Annikan,

Sounds like the sacral section has more potential for change than the lumber section?
Does having the sacral section set up with more extension prevent or promote movement in that direction during the swing?

Also would like to hear Vicki's opinion on this subject!

Stricker's posture looks much more natural to me.

Sorry that's Badds and Grant Waite..


Natural doesn't mean neutral.....or does it?


The Thoracic Spine with a Rotated Shoulder Turn has more changes to the spine than that of the Flat Shoulder Turn....

Dunno..ask Vicki..

Vicki?

[Homerson]

Vicki Lake...Maybe that's out of her realm of expertise!

"The Thoracic Spine with a Rotated Shoulder Turn has more changes to the spine than that of the Flat Shoulder Turn...."

How so?
Backswing? Downswing?

[annikan skywalker]

I showed you in the Creek!!!!

RE-MEMBER!!!!!!!

[Homerson]

Still incubating but words help!
Understand the effects on head centre, hip tilt, and waist bend. Just haven't transferred that knowledge to ball flight changes.
There's a lot to it you know

When, where, and why do these spine angle changes occur in the Throacic Area? Why are there more changes in the Rotated than the Flat Shoulder Turn?
