Golf is difficult because the club leaves the visual field and everything from the shoulder to clubhead disappears into this dark space behind you. When you play well, it is automatic and in the groove.
To put you in the picture:
Golf relies heavily on the Visual-spatial system- “where you are in relation to the ball and the club.”
Usually, the Visual-Spatial System input relies on:
Visual counts for 80%
Inner ear counts for 15%
Proprioception counts for 5%- (this is the ability to know where your hand is behind your back)

So once the arm and club leave the visual field, the brain has to rely almost entirely on PPC to know where the right shoulder, elbow, wrist, hand, and clubhead are in this dark space behind you. With little help from the visual system
When the brain misfires, the golfer’s swing leaves the groove, and the golfer “lost his swing.”
Power Therapy deals with this issue.

Jordan has been incredibly open with the public via his media appearances. This study argues that there are reasons beyond anxiety, choking, and psych—mind that can play havoc with athlete performance. I wish to thank Jordan for discussing his own reflections on which this case study expands. With special thanks to No Lay Up podcast 206—Jordan Spieth.
