Here is bit of info on how golf will be integrated in to the Olympics in the US. The US Olympic Committee has all the Olympic Sports divided up into groups that teams of "performance specialists" work with; Technology, Biomechanics, Nutrition, Psych, Physiology etc. We call them Sportfolios. I am one of the sport technologists/biomechanists. Golf is in my sportfolio (along … [Read more...]
Analyzing the Golf Swing in 6 Degrees of Freedom with AMM 6DOF Systems
What is 6DOF? Six-degrees-of-freedom (6DOF) means you can move six ways; forward/backward, left/right, up/down; these movements are linear, determine your position and are measured in feet, inches, meters etc. You can also turn, plus bend forward/backward or side to side; these movements are angular, determine your orientation and are measured in degrees. When you measure … [Read more...]
The Importance of Stretching the X-Factor in the Downswing of Golf: The X-Factor Stretch
Back in 2000 my colleagues and I wrote a paper where we showed that an increase in the X-Factor at the beginning of the downswing seemed to be more important that the X-Factor itself. We called this the “X-Factor Stretch”. Jim McLean is well known for his teaching of the X-Factor and has also mentioned in several articles that the hips should turn into the downswing before … [Read more...]
When does the Pelvis Begin to Decelerate in the Downswing of Golf?
In order to create maximum speed of a distal segment or implement, the principle of the kinematic sequence (a.k.a kinetic link) shows that each body part, should accelerate then decelerate in a sequential manner. For the golf swing, to achieve maximum club speed, the sequence is pelvis, thorax (ribcage), lead arm, club shaft. This means that during the downswing the pelvis … [Read more...]
