In this deep-dive panel from Open Forum 3, world-renowned biomechanist Dr. Young-Hoo Kwon is joined by Dr. Mike Duffy (Penn State), Dr. David McGhie (Swing Catalyst), and elite coach Rob Holding to answer critical questions about Ground Reaction Forces (GRF). The panel explores the nuances of how golfers interact with the ground to create speed and stability.
Topics include the difference between pressure and force, the importance of the "moment arm," why restricting your pressure shift limits your dynamic potential, and the biomechanical reality of "right-sided" hitting.
Whether you are a golf coach or a serious player looking to understand the physics of the swing, this discussion provides elite-level insights into the mechanics of the modern golf swing.
