Method and computer-readable storage medium for fitting tennis racket and analysis device

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.

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.
