Golf is a sport of complexity, for that there is no doubt; and with so many factors determining the final resting place for that little white ball, it is essential to eliminate as many of these factors that are with-in your control as much as possible. One of these factors is your intrinsic biomechanics:
There are two types of biomechanics:
Extrinsic Biomechanics looks at the actual mechanics of the swing. How the player addresses the ball, their take-away, backswing, downswing, impact and finish. (I’ll leave this part to Simon Tillson!). Although this is without a doubt the make of any good player, it is how the body achieves this intrinsically that will determine how consistent they will be and how much at risk they are to injury.
Intrinsic Biomechanics is how the body functions during the golf swing; looking at what compensations maybe happening intrinsically in order to perform the extrinsic movement of the golf swing.
Let me give you an example:
Leg length discrepancy is defined as a difference in leg length. This could be genuine, i.e.
A longer femur in one leg, or it could be biomechanical, i.e. pelvic rotation.
How this affects the golfer
A difference in leg length will inevitably open the player up to potential injury, while hampering their golf. This will reduce the golfer’s ability to rotate, and therefore the golfer will have to side bend (which relieves the load on the facet joints) to allow rotation. This could lead to many swing faults and create inconsistency during the swing and may cause back injuries on and off the course.
To create the desired movement extrinsically -by making the body biomechanically sound, the golfer can work on their fitness and strengthen the body (in particular the core). In a better position, and then by practising and working on their swing, they know that their body is not compensating intrinsically.
The result, better and safer golf!
