Abstract

A tennis swing analyzing apparatus of the present invention is an analyzing apparatus configured to analyze a tennis swing in a groundstroke, a volley, or a serve. The analyzing apparatus includes a triaxial acceleration sensor attached to a tennis racket including a grip and a head, and configured to measure acceleration in each directions of three axes when a swing for hitting a tennis ball is performed with the tennis racket; a triaxial gyroscope attached to the tennis racket and configured to measure angular velocity about each of three axes when the swing for hitting a tennis ball is performed; and an analyzing device. The analyzing device has a reception function for receiving data related to the acceleration and the angular velocity from the triaxial acceleration sensor and the triaxial gyroscope; a coordinate axis conversion function for converting a relative coordinate axis of the acceleration into an absolute coordinate axis based on the angular velocity; and a calculation function for calculating a swing indicator based on acceleration resulting from the coordinate axis conversion.
