1. A golf swing analysis apparatus for analyzing a swing action of a golf club, comprising:
- a communication device;
a storage;
an acquisition unit of a processor configured to acquire a measurement value obtained by measuring the swing action using a measurement device from the measurement device via the communication device and store the measurement value in the storage;
a grip behavior derivation unit of the processor configured to derive a behavior of a grip of the golf club that occurs during the swing action, based on the measurement value stored in the storage; and
a shoulder behavior derivation unit of the processor configured to derive a behavior of a pseudo shoulder of a golfer that occurs during the swing action, based on the behavior of the grip, the behavior of the pseudo shoulder including a rotary motion of the pseudo shoulder,wherein the grip behavior derivation unit is configured to derive the behavior of the grip in a global coordinate system, and transform the derived behavior of the grip into a behavior in a swing plane, andwherein the shoulder behavior derivation unit is configured to derive the behavior of the pseudo shoulder in the swing plane, based on the behavior of the grip in the swing plane.
