<P>PROBLEM TO BE SOLVED: To provide an evaluation method having excellent evaluation accuracy for hit feeling of a sport implement. <P>SOLUTION: The evaluation method for hit feeling of a sport implement includes: an acceleration measurement step of measuring acceleration of a sport hitting tool 4 for hitting and a data analysis step of analyzing data obtained in the measurement. In the data analysis step, the amount of change in acceleration in a first cycle of vibration after hitting is calculated. The evaluation method evaluates hit feeling to be felt by a person, using the amount of change in the acceleration. Preferably, in the data analysis step, the amount of change in acceleration in the first cycle of predetermined time is calculated. The predetermined time is within 1.5 msec from the time of hitting. Preferably, the sport hitting tool 4 has a hitting section detachably attached to a shaft section. <P>COPYRIGHT: (C)2013,JPO&INPIT |
