Thinking
"Outside Of The Box" |

To
further condition the deep stabilizing muscles of the trunk
everything outside “the box” (arms, legs, neck
and head) must be lengthened away from the trunk. This occurs
while the trunk muscles are engaging in toward the center
of gravity ( your core).
Lengthening the arms away from a stabilized shoulder girdle promotes strength
in the muscles of the shoulders and upper back.
The joint capsules of the limbs are opened up, and the limbs are lengthening
both eccentrically and concentrically, further enhancing the strength they need
to stabilize for the centrifugal force of the golf swing. |

The
Rotator Cuff (musculotendinous cuff) of the shoulder is a
set of four functional muscles: supraspinatus, infraspinatus,
teres minor, and subscapularis. Their function is to prevent
the humerus from dislocating at the glenohumeral joint (shoulder
socket or glenoid cavity) by forming a cuff around the humeral
head and holding it into the socket. These four muscles originate
from differing points of the scapula and insert on the humerus
and also assist in abduction, internal rotation, external
rotation, and adduction of the upper arm.
When the arm is lengthened away from the shoulder the proprioceptors sense the
potential for dislocation of the humerus from the glenoid cavity and cause the
stretch reflex to shorten the muscles as a protective mechanism. The shoulder
stabilizers do not lengthen toward the directional reach of the arm but rather
engage working to pull the humerus in, preventing dislocation from the centrifugal
force generated by the swing. |
