Beyond the Kinetic Chain Process in a Stroke using a Triple Pendulum Model

Abstract

The efficient way to transfer input potential energy to the kinetic energy of a racket or bat was analyzed by two coupled harmonic triple pendulums. We find the most efficient way to transfer energy based on the kinetic chain process. Using control parameters, such as the release times, lengths and masses of the triple pendulum, we optimize the kinetic chain process. We also introduce a new method to get an efficient way to transfer initial energy to the kinetic energy of the third rod in the triple pendulum without time delay, which is considered an essential part of a kinetic chain process.
