<p><P>PROBLEM TO BE SOLVED: To provide a swing analysis device easy to handle with a comparatively simple configuration, objectively deciding a state of an impact. <P>SOLUTION: This swing analysis device 1 includes at least an angular velocity sensor 100, an impact detection part 202, an angular velocity information calculation part 203, and an impact state decision part 204. The impact detection part 202 detects timing of the impact in a swing of a sports implement. The angular velocity information calculation part 203 calculates at least one of a change amount of angular velocity to a prescribed axis within a prescribed time from the timing of the impact and the maximum value of the angular velocity based on output data of the angular velocity sensor 100. The impact state decision part 204 decides the state of the impact based on the calculation result of the angular velocity information calculation part 203. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
