Abstract

An aspect of the invention relates to a golf swing analyzing apparatus, comprising: an arithmetic section operating to use the output of an inertial sensor to calculate bending moment acting on the golf club, the inertial sensor being attached to the golf club.

Claims

1. A golf swing analyzing apparatus comprising an arithmetic section operating to use an output of an inertial sensor to calculate bending moment acting on a golf club, the inertial sensor being attached to the golf club.

2. The golf swing analyzing apparatus according to claim 1, wherein the arithmetic section operates to calculate a maximum value of the bending moment.

3. The golf swing analyzing apparatus according to claim 1, including an image data generating section generating an image data for displaying a change of the bending moment.

4. The golf swing analyzing apparatus according to claim 1, wherein the arithmetic section operates to calculate an elapsed time from a beginning of a downswing to an establishment of a maximum value of the bending moment and an elapsed time from the establishment of the maximum value to an establishment of a minimum value of the bending moment.

5. The golf swing analyzing apparatus according to claim 4, wherein the apparatus operates to calculate a time point of the establishment of the maximum value of the bending moment in a period from the beginning of the downswing to an impact to present a hardness of a shaft of the golf club.

6. The golf swing analyzing apparatus according to claim 1, wherein the inertial sensor includes an acceleration sensor and a gyro sensor.

7. A method of analyzing golf swings, comprising:

processing an output of an inertial sensor to calculate bending moment acting on a golf club, the inertial sensor being attached to the golf club.
