Power Accumulation and Swing Patterns

Power Accumulation and Swing Patterns

These terms coined by Homer Kelly serve us well to explain how out of line conditions seeking a straight line can release stored energy to enable us to vary power out put, what we have to understand also is that as individuals it becomes apparent that we all swing the club differently and thus some people tap into one particular power accumulator more readily that others (finding one more natural), thus giving us different looking patterns to our golf swings.

So how does this work, well first of all there are 4 accumulators:

#1(Muscle Power) is a bending right arm, which is always striving for a straight line condition, this is controlled via the right triceps muscle always pushing away from the glenohumeral joint of the right shoulder, the left arm prevents the right arm from achieving this in the backswing, thus the right arm folds during backswing right arm external rotation and abduction (away from the midline).
#2 (Velocity power) is the cocking and unlocking of the left wrist, remember that radial and ulnar deviation is a small motion, controlled by the forearms.
#3 (Transfer Power) is the turning and rolling of the forearms, pronation and supination.
#4 (Radius Power) this is the angle of the left arm and left shoulder, at address the angle would be close to 80/90 degree angle, that angle decreasing during the backswing and vice versa on the downswing.

So a flat shaft plane in the backswing at P3 would be an over utilisation of the #3 Power Accumulator thus overriding the #2 power Accumulator which creates the up in the backswing, so simply reverse engineer this applying a anti clockwise rolling action in the backswing, this will cause the #3 accumulator to become less active thus stimulating the use of the #2 accumulator allowing a steeper more on plane backswing.
