Abstract: A measurement device outputs first and second swing measurement data values respectively dependent on operability of a hitting tool (bat) and momentum at the time of impact with a swing behavior when hitting an object (ball) with the hitting tool being employed as an input. A data analysis device generates diagnosis information for selection of a hitting tool in response to input of the first and second swing measurement data values obtained when each of three or more of hitting tools is swung. The diagnosis information is generated using a total score value calculated by integrating, using a BS value that is a weighting coefficient, a score value that is an indicator value of operability of the hitting tool calculated from the first swing measurement data value and a score value that is an indicator value of a hit-object speed calculated from the second swing measurement data value.

The through hole includes a base opening, a side wall, and a non-circular tip opening. Assuming an imaginary dividing plane that is perpendicular to a face of the racket and that divides the non-circular tip opening into a first opening portion and a second opening portion shorter than the first opening portion in a direction parallel to the face, an inside dimension of the first opening portion in the direction perpendicular to the face increases gradually from one end of the non-circular tip opening in the direction parallel to the face to the dividing plane. In the tubular part, the string passes through the first opening portion and is in contact with the side wall from the base opening to the tip opening.
