Joe Norwood is perhaps one of only a few golf instructors specifically mentioning the role of the trail shoulder in his book 'Golf-O-Metrics'.
''Stead steady, toss the hand/wrist/forearm to the right shoulder, then use the right shoulder to power the downward thrust. Using the right shoulder means coming out of the shoulder – thrusting out of the shoulder, not turning the shoulder/torso in a twisting action.''
He refers on several occasions to cranking into the right shoulder, the shoulder blade area, activating the booster muscles in that area, etc..
Let's look next at an article published by Kibler and McMullen in the Journal of the American Academy of Orthopaedic Surgeons
Scapular Dyskinesis and Its Relation to Shoulder Pain
W. Ben Kibler, MD, and John McMullen, ATC
''The final role that the scapula plays in shoulder function is as a link in proximal-to-distal sequencing of velocity, energy, and forces of shoulder function. For most activities, sequencing begins at the ground, and individual body segments (links) are coordinated by muscle activation and body position to generate, summate, and transfer force through these segments to the terminal link. This sequence is termed the kinetic chain. These serial muscle activation patterns stabilize the scapula and increase the control of its motion and position as the arm is moved. The scapula is thus pivotal in transferring large forces and high energy from the legs, back, and trunk to the delivery point, the arm and the hand, thereby allowing more force to be generated in activities such as throwing than could be done by the arm musculature alone. The scapula, serving as a link, also stabilizes the arm to more effectively absorb loads that may be generated through the long lever of the extended or elevated arm.''
Old timer Joe Norwood, perhaps entirely intuitive, with his emphasis on role of the right shoulder, seemed to have been right on the money.
