In order to analyze a skill such as the golf swing, we have to measure it. To do that we need one or more reference frames, also known as coordinate systems. Reference frames consist of a zero point and three perpendicular axes, usually called, the X, Y and Z axes, which originate from this origin. There is always one global reference frame from which everything else is … [Read more...]
Biomechanics Every Golf Instructor Should Know – Part 1
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...]
Linear and Angular Speed in the Golf Swing
What is the difference between linear and angular speed or velocity and how can something moving in a circle have a linear velocity? I know this is a point of confusion in some golf instructors minds, and I teach basic biomechanics to track and field coaches and this one stumps them too. If you have a rock on a string and you are swinging it in a circle then the string has an … [Read more...]
