PROBLEM TO BE SOLVED: To provide a motion analysis device and a motion analysis system in which motion analysis can be performed with high accuracy.SOLUTION: A motion analysis device 20 includes a processing unit 200 for performing a motion analysis of a subject by using an output of a sensor unit 10. The sensor unit 10 includes an angular velocity sensor 110 capable of measuring an angular velocity of at least 2500 dps, a second acceleration sensor 102 capable of measuring an acceleration of at least 50 G, and a first acceleration sensor 100 capable of measuring an acceleration of at least 24 G. The sensor unit is mounted in at least one of a golf club and a subject. The processing unit 200 calculates a posture of the sensor unit 10 in the motion by using the angular velocity measured by the angular velocity sensor 110, and selects the output of the second acceleration sensor 102 and the first acceleration sensor 100 according to the acceleration applied during motion, and thereby calculates a position of the sensor unit 10 during the motion by using the acceleration of the selected sensor. |
