Presented at the LPGA National Teaching and Coaching Summit October 7, 2015 This is part one in a series that I will be producing on the basics of biomechanics specifically applicable to golf. It is biomechanics that every golf instructor should know. My personal background is included as an introduction and then, definitions of biomechanics, kinematics and kinetics are … [Read more...]
Basic Biomechanics for Golf: Selected Golf Topics
Recently, in the Facebook golf groups there has been a lot of interest in basic biomechanics principles, so I thought I would post this document. I originally wrote it last year for the LPGA to be incorporated as part of their Integrated Performance System. It presents selected topics on basic biomechanics principles for the golf swing. The topic covered … [Read more...]
My PhD Dissertation
I am finally able to publish my PhD dissertation on my website. I have included the abstract, a pdf of the full dissertation and a pdf of the presentation that I made to my committee on June 26 2014, in defense of my dissertation. I actually started my PhD at Arizona State in 1992! I did one year and then started Skill Technologies and then AMM. So life got in the way and … [Read more...]
Two Spine Models: Rigid and Two-Segment
There are several ways to biomechanically represent the spine during the golf swing using motion capture technology, here are two examples, the rigid spine method and the two-segment spine method. Rigid Spine Method The rigid spine method uses markers or sensors to define the left and right shoulders plus the right and left hips. A point mid-way between them is calculated and … [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...]
