In Part 4, the discussion will continue with some concluding thoughts as well as a description of a performance based activity example.

In The Golfing Machine, Mr. Kelley discusses the importance of Structure, in section 1-D when he states:

If the biomechanical system has any alignment distortions in Quiet Upright Standing, then these mis-alignment distortions may be magnified further when moving to GBP™.  The goal for aspiring student golfers is to strategically pose the biomechanical system to as much of a “plumb, square, and level” state of alignment as is possible in Quiet Upright Standing first, prior to forming GBP.

In Part 3, the discussion will continue with a focus on performance based concepts with respect to the avoidance of over-activation of the QL. Increased muscular tension of the QL poses the potential for a Pivot Blocking effect. One such example of a mechanism permitting increased muscular tension of the QL was discussed in the previous article with a brief description of Lower Cross Syndrome.

To review, using the reference, Management of Common Musculoskeletal Disorders, Fourth Edition, by Darlene Hertling BS, RPT and Randolph M. Kessler, MD, With Contributors (Lippincott Williams & Wilkins, A Wolters Kluwer Company), on page 150, Lower Cross Syndrome’s QL effect was described:

In Part 2, the discussion will focus on more clinically related pertinent elements associated with the QL.  Part 1 provided information about the QL’s origin, insertion, resultant joint action, as well as its powerful assistance (for lateral flexion of the lumbar spine) with ipsilateral (same side) contribution provided by the internal and external oblique muscles.

The activities of daily living of each golfer outside that of golf participation along with inherent biomechanical related vertebral column functional and structural alignment characteristics are key foundation based factors that will “calibrate” how the QL will “behave” upon comporting the biomechanical system to the alignments and pose arrangements of GBP™.
