Abstract
A swing analyzing device comprising swing practice equipment such as a golf club, wherein acceleration sensors are arranged on the shaft or on an axis of the swing practice equipment, or near the axis, and a dynamic quantity representing a movement of the shaft, such as an angular velocity, angular acceleration, and angle of the shaft, is calculated from an output of the acceleration sensors. The acceleration sensors are preferably arranged on the shaft in a spaced apart relationship so that directions of detecting acceleration substantially coincide with an axis of the shaft. A further acceleration sensor can be arranged on the shaft so that a direction of detecting acceleration forms a certain angle with an axis of said shaft.
