In this study, we conducted the 3-axis acceleration analysis of figure skating jump using inertial sensors. In the motion measurement of figure skating jump, the measurement area is wide, and the figure skater conducts high speed rotational motion. Therefore, we used the inertial sensor system as simply motion measurement device. We conducted the measurement experiment of the figure skating jump by a high-level figure skater, we obtained the 3-axis measurement information of inertial sensors in the triple flip jumps and the quadruple salchow jumps. The results of combining angular velocity and acceleration indicated the high repeatability. Furthermore, we conducted the 3-axis acceleration analysis in quadruple salchow jumps using the sensor outputs and the self-assessment. The result of high point in self-assessment indicated the high acceleration, and the effect by composite axis component in centrifugal acceleration was indicated. These results indicated the importance of body inclination during the jump motion.
