On Monday, Chris Welch of Welch-e Technologies gave us a brief overview of the X-Factor and Triple X-Factor concepts that have caused much debate recently.
He talked about how the body utilizes a movement pattern referred to as the “stretch-shorten cycle” during the golf swing to create muscular potential and produce more work or power output.
Muscles in the golf swing are pre-stretched prior to contraction. The pre-stretch begins in the back swing but finishes in the down swing and results in more force or work output by the muscles as the golfer creates club head speed. The pre-stretch process is referred to as the "stretch-shorten cycle."
It occurs during the down swing, NOT the back swing and is most dependant on the rate of stretch and the rate of transition from stretch to shorten, NOT the amount of stretch.
Tonight, in this video, Chris explores the “stretch-shorten cycle” in the golf swing and sheds some light on the myths and misconceptions while at the same time providing valuable information about golf swing technique and training.
