<p>PROBLEM TO BE SOLVED: To provide a motion analysis method, a motion analysis device and a motion analysis program for specifying a ball hitting direction from a swing motion without being influenced by a direction of a body.SOLUTION: In a motion analysis method, an impact time analysis unit 48 specifies a posture of a ball hitting surface of a sports implement at the time of an impact by using output of an inertial sensor 12. A determination unit 55 determines a trajectory type of ball hitting by using information of the posture of the specified ball hitting surface. The trajectory of the ball hitting is estimated by the posture of the ball hitting surface at the time of the impact. The trajectory type is determined according to the posture of the ball hitting surface.</p> |
