GOLF SWING ANALYZING APPARATUS AND METHOD OF ANALYZING GOLF SWING
First Claim
1. A golf swing analyzing apparatus, comprising:
- a first arithmetic section operating to use an output from a first inertial sensor and an output from a second inertial sensor to calculate a first energy amount, the first inertial sensor being attached to a portion of an upper body of a golfer, the second inertial sensor being attached to a golf club, the first energy amount being generated at the upper body of the golfer;
a second arithmetic section operating to use the output from the first inertial sensor and the output from the second inertial sensor to calculate a second energy amount transferred to the golf club from the upper body of the golfer; and
a processing section calculating an energy transferring ratio of energy transferred from the upper body of the golfer to the golf club based on a ratio of the second energy amount to the first energy amount.
