METHOD AND COMPUTER-READABLE STORAGE MEDIUM FOR FITTING TENNIS RACKET AND ANALYSIS DEVICE
First Claim
1. A tennis racket fitting method comprising:
- a first step of preparing a plurality of test tennis rackets, at least one type of racket property that influences swing for hitting a ball being defined for each of the test tennis rackets;
a second step of causing a reference tennis racket to be swung at least one time by a user in order to hit a tennis ball, and acquiring a measured value by measuring transition in at least one of the position, the velocity, the acceleration, and the angular velocity of the reference tennis racket in at least a portion of an interval from when the swing starts until when the swing ends;
a third step of calculating at least one evaluation indicator to be an evaluation of the swing of the reference tennis racket based on the measured value; and
a fourth step of, based on the racket property, selecting a tennis racket that can improve at least one evaluation indicator from among the test tennis rackets.

9. A non-transitory computer-readable recording medium storing a tennis racket fitting program for causing a computer to perform:
-
a first step of storing information regarding a plurality of test tennis rackets, at least one type of racket property that influences swing for hitting a ball being defined for each of the test tennis rackets; a second step of, when a reference tennis racket is swung at least one time by a user in order to hit a tennis ball, receiving, as a measured value, transition in at least one of the position, the velocity, the acceleration, and the angular velocity of the reference tennis racket measured in at least a portion of an interval from when the swing starts until when the swing ends; a third step of calculating at least one evaluation indicator to be an evaluation of the swing of the reference tennis racket based on the measured value; and a fourth step of, based on the racket property, selecting a tennis racket that can improve at least one evaluation indicator from among the test tennis rackets. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An analyzing apparatus for tennis racket fitting comprising:
-
a first storage unit storing information regarding a plurality of test tennis rackets, at least one type of racket property that influences swing for hitting a ball being defined for each of the test tennis rackets; a second storage unit storing, when a reference tennis racket is swung at least one time by a user in order to hit a tennis ball, as a measured value, transition in at least one of the position, the velocity, the acceleration, and the angular velocity of the reference tennis racket measured in at least a portion of an interval from when the swing starts until when the swing ends; a calculation unit that calculates at least one evaluation indicator to be an evaluation of the swing of the reference tennis racket based on the measured value; and a racket selection unit that, based on the racket property, selects a tennis racket that can improve at least one evaluation indicator from among the test tennis rackets.
