Abstract

The present disclosure is directed to systems and methods for analyzing the motion of a sporting equipment, such as a golf club, a baseball bat, a hockey stick, a football or a tennis racquet, for example. The systems comprises a motion sensing system in communications with the sporting equipment to measure motion parameters, wherein the motion sensing system has at least one at least one accelerometer or at least one gyroscope, and a command station having a data acquisition system to process the measured motion parameters and produce data. The motion sensing system may be located on the sporting equipment or, optionally, within the sporting equipment. The systems and methods described herein can be used to determine the impact location of the sporting equipment with another object, the force of the sporting equipment, the velocity of the sporting equipment and/or the angular orientation of the sporting equipment during a motion.
