This is nothing more than a TGM Pivot for a Straight Line Delivery Path.

Golf biomechanics applies the principles and technique of mechanics (Alignments and Physics) to the structure and function of the golfer in an effort to improve golf technique and performance. A common recommendation for technical correction is maintaining a single fixed center hub of rotation (Stationary Head) with a two-lever one-hinge moment arm (Primary and Secondary Levers with a Cocked Left Wrist) to impart force on the ball. The primary and secondary spinal angles (Waist bend and Tilt) are important for conservation of angular momentum using the kinetic link principle (Pivot controlled Hands) to generate high club-head velocity. When the golfer wants to maximize the distance of their drives, relatively large ground reaction forces (GRF) need to be produced (Swing from the Feet). However, during the backswing, a greater proportion of the GRF will be observed on the back foot (the Back Right Foot), with transfer of the GRF on to the front foot (front right foot) during the downswing/acceleration phase (Hey, what about the left Foot, it has important functions too). Rapidly stretching hip, trunk and upper limb muscles during the backswing, maximizing the X-factor early in the downswing, and uncocking the wrists when the lead arm is about 30 degrees below the horizontal (Please, hackers only. Better Golfers Hands will pass the line of sight to the ball at Release) will take advantage of the summation of force principle. This will help generate large angular velocity of the club head, and ultimately ball displacement (Faster Clubhead speeds make the ball go farther). Physical conditioning will help to recruit the muscles in the correct sequence and to optimum effect (Physical connditioning may help you swing faster). To maximize the accuracy of chipping and putting shots, the golfer should produce a lower grip on the club and a slower/shorter backswing. Consistent patterns of shoulder and wrist movements and temporal patterning result in successful chip shots (practice makes perfect). Qualitative and quantitative methods are used to biomechanically assess golf techniques (the guy with the longest drive has better technique). Two- and three-dimensional videography, force plate analysis and electromyography techniques have been employed (because they have no clue whats happening when they observe a Golfer). The common golf biomechanics principles necessary to understand golf technique are stability, Newton's laws of motion (inertia, acceleration, action reaction), lever arms, conservation of angular momentum, projectiles, the kinetic link principle and the stretch-shorten cycle. Biomechanics has a role in maximizing the distance and accuracy of all golf shots (swing and putting) by providing both qualitative and quantitative evidence of body angles, joint forces and muscle activity patterns (10% pay raise per year if BioMechanists Unionize). The quantitative biomechanical data needs to be interpreted by the biomechanist and translated into coaching points for golf professionals and coaches (not enough money teaching kids). An understanding of correct technique will help the sports medicine practitioner provide sound technical advice and should help reduce the risk of golfing injury. (Golfer says: “It hurts when I do this”, the Doctor replies: “then stop doing it”.)
