Looks like the 4 sections of the spine experiencing changes to maintain a steady pivot center is kickin arse...Wonder why?
annikan- can you please explain how the 4 sections of the spine precisely change in relation to the 3 planes throughout the swing (for eg: by the halfway point in the backswing the cervical has ------ relative to the lateral plane, -------- relative to the sagittal and ------- with respect to the transvere, while the thoracic has ... etc.) to maintain the steady pivot center. thanks.
[quote=annikan skywalker]Really... At first glance...perhaps....maybe looking at it from a different perspective might help to reevaluate....
In reality the spine is never in a perfect straight line condition. What I was meaning to convey (and others have subsequently) that the lowest point of the spine and the uppermost point remain in the same place and if a line was drawn through those two points, that would represent the spine angle (someone mentioned torso angle that better represents the idea IMO).
First of all ...we are all built differently than each other....But I fel we should work from the bottom...let's just study the Pelvis and the sacrum first...
Notice the Neutral Postion of the pelvis is approximatley 30 degrees..
Let's first discusst the motion of the pelvic girdle with Anterior Rotation and Posterior Rotation of a NON Golfer...
then let's applly this to a golfer...throughout the next few weeks we will begin to discuss each segment in each plane and it's axis of rotation through each section as suggested by djd...so we will move slowly....so noone gets lost....
Question #1. Anterior Rotation(Forward) of the Pelvis affects the Lumbar Spine Motion and the left and right hip in what manner?
Anterior Rotation Extension of the Lumbar spine....Flexion at the right and left hip respectively.....Anyone know what that looks like..Pick A, B, C, D, or E

Rule #1
We will use markers on each of the major joints and draw plane and axis of rotation.(As indicated by the red dots and yellow lines) Rule #2
We will use a "qualitative approach which describes the motion as opposed to a quantitative approach which is measured to the degree of motion. ( for instance slight amount of flexion rather than 10 degrees of flexion)
Rule #3
Different types of stroke patterns have similar but in some cases different movements Rule #4
We will work through this one segment and section at a time Rule #5
I do not have All the answers...So if there are any experts in the field of Kinesiology or similar field...feel free to contribute insight...
