Summation of segmental velocities in the golf swing.

Abstract:

:The downswing phase in golf was represented as a double pendulum pivoted at the shoulder joint and hinged at the wrist. The motion of such a pendulum was used to derive a series of equations which were used to describe the instantaneous values of several of the component features of the downswing. Results of this analysis showed that an initial delay in the uncocking of the wrist would allow (a) acceleration of the arm to reach a greater value and (b) the acceleration of the club to be summed with the existing maximum angular acceleration of the proximal segment.
