3D Swing Systems

Analyzing a golfer's swing using 3D technology has come of age. Professional players have had access to the methodology for years and just about everyone on the modern tours has benefited from it. Biomechanics analysis of a swing on a regular basis can track changes, both good and bad, during the tournament season. Coaches, instructors, and trainers use the data to fine tune player performance.

The most comprehensive approach to 3D swing analysis has been undertaken by the professionals at TPI. Greg Rose and Dave Phillips together with several experts including Phil Cheatham have done the hard work of analyzing large number of swings and applying professional biomechanics knowledge to interpreting the data and selecting the most effective equipment for the measurements. The understanding comes from integrating golf instruction, fitness professionals, biomechanics, medical professionals, and golf technology into the most extensive system anywhere.

An important key to using 3D swing analysis systems is having a meaningful database to use in understanding what a player does to generate an efficient repeatable swing -- a swing that allows full power to be developed without excessive movement. The models and conclusions drawn from the analysis should be based on what works in the real world of golf not a theory or an opinion.

Cost of the 3D analytical equipment dropped, and understanding of the limitations of conventional video increased. This combination stimulated the development of portable systems that can be set up quickly. The first practical system that has kept pace with technology is the K-Vest. It uses 3 motion capture sensors to measure the rotational speed around three axes and communicate wirelessly to a computer. A sensor on the pelvis, thoracic spine, and lead hand provides the most important data needed to understand the kinematics of a golf swing.

The K-Vest system incorporates the TPI analytical approach and uses reference data from the extensive database developed at TPI for thousands of pro and amateur swings. The database is an essential component for developing models and comparing your swing to what actually works with the best and most effective players in golf. This system provides access to the best professional analysis and expertise in golf that we have not seen to this extent in any other competing system.
