PROBLEM TO BE SOLVED: To provide a motion analysis device, a motion analysis system, and a motion analysis method and program, which can evaluate a swing simply and objectively.SOLUTION: A motion analysis device is characterized by comprising: an angle detection part for determining a change in a rotation angle to occur around the axis of a shaft part of a motion tool in a swing by using the output of an inertial sensor; and an evaluation part for performing the evaluation of at least a portion from the start to the end of the swing, on the basis of the change of the rotation angle.SELECTED DRAWING: Figure 10 |
