GOLF CLUB FITTING METHOD, DEVICE THEREOF, AND ANALYSIS METHOD
First Claim
1. A golf club fitting method, comprising steps of:
- preparing a relation C1 in which a face angle before or at ball impact and a hitting result are considered, wherein the face angle and the hitting result are measured when a plurality of golf players makes swings using a plurality of golf clubs with different values of shaft physical properties;
obtaining a measurement result of the face angle by a subject (golf player) hitting a ball with a test club; and
determining a shaft physical property which fits the subject on the basis of the relation C1 and the measurement result of the face angle.

Abstract
The analysis method includes steps of acquiring measurement data obtained from swings and values of hitting results (flight distance or the like) (STEP 3); calculating a characteristic value (face angle or the like) from the measurement data (STEP 4); and determining an indicator for selecting a shaft of a golf club from the characteristic value and the values of hitting results (STEP 5). In the step of determining an indicator, when a hitting result of a golf club is an objective variable, and the characteristic value is an explanatory variable together with a predetermined shaft physical property (flex point or the like), and has a statistically significant relation with the hitting result, the characteristic value is determined as the indicator. A relational expression of the indicator and the hitting result is calculated for each value of the physical properties.
