Abstract

本研究は,テニスサーバーの動作とレシーバーの予測の定量的関係性について,ラケット動作パラメータを説明変数,レシーバーのコース予測判断を従属変数とする重回帰分析によって明らかにすることを目的とした.12名のテニス熟練者および12名の非熟練者は,時間遮蔽で編集されたビデオ映像を観察し,テニスサービスのボール方向をvisual analog scale(VAS)により判断した.ラケットとボールのコンタクト直前の遮蔽において,熟練者群の正答率はチャンスレベルを超えているものの,非熟練者群の正答率はチャンスレベルを超えなかった.さらに,熟練者群のVASスコアを対象とした重回帰分析の結果では,ラケット動作パラメータは熟練者のボール方向の予測スコアを10.3%で説明した.この結果は,ラケット動作情報と熟練者の予測との関係があることを示している.

The aim of this study was to clarify the quantitative relationship between tennis server's motion and receiver's anticipation with a multiple regression analysis by using the racket's kinematic parameters as explanatory variables and anticipatory judgment of ball direction as a dependent variable. Twelve expert tennis players and 12 novice players scored their anticipatory judgment of the ball direction on a visual analog scale (VAS) of tennis serves after observing video images edited in a temporal occlusion paradigm. At occlusion onset before the moment of racket-ball contact, the correct responses of expert players were above chance level but not those of novice players. Furthermore, the result of the regression analysis on the expert players' VAS score showed that the racket's kinematic parameters explained 10.3% of the anticipated score of ball direction for expert players. This result indicates that there is a linkage between the server's racket kinematics and the expert's anticipation.
