  • Patent number: 5823878
    Abstract: A golf analysis apparatus and method which uses videotaping equipment to capture golf swing motions from at least two different angles, and video processing equipment to isolate video frames for global, three-dimensional orientation of chosen points on the test subject. The points are compiled and used to calculate such parameters as clubhead lag and resultant clubhead velocity, body segment rotations, joint range of motion, spine angle, and center of mass versus center of pressure. Velocity data is used to calculate acceleration data. Such velocity and parameter data is then plotted simultaneously as part of an analysis method to determine and optimize the kinetic link between various body parts. For example, by locating the peaks of simultaneously plotted hip, shoulder, arm, and club release speed data, it can be determined if such peaks occur in the proper sequence for translating maximum power through the swing.
