本文之目的為研究臺灣職業網球選手詹家姊妹在發球局及接發球局的女子雙打最佳贏球策略,提供網球教練及選手作為參考,以提升成績表現。研究對象為詹家姊妹2015~2018年的12場比賽,共計24名選手,由具有國家級教練之專家,透過觀賽影片將各場每一球的比賽過程,根據設計的因子及水準進行模式記錄,採用田口理論中具有望大特性的訊號雜訊比進行最佳化分析。研究結果指出:詹家姊妹在發球局的最佳贏球模式為詹詠然發球,第一發球進並落點朝接發球者身體,網前搭檔詹皓晴搶打截擊朝對方空檔得分;在接發球局時為詹詠然接發球,接進第二發球並落點朝斜線,網前搭檔詹皓晴搶打截擊朝對方身體得分。本文所得結論:詹家姊妹的比賽站位為一前一後之方式,在發球局或接發球時的最佳得分陣型,皆為詹詠然位於底線對峙,詹皓晴位於網前伺機搶打截擊,由詹詠然主導戰力,製造詹皓晴攻擊得分的機會。
This study analyzed the winning strategies of professional Taiwanese women's doubles tennis players Yung-Jan Chan and Hao-Ching Chan (the Chan sisters) on server or receiver games. In order to identify and promote the integral elements of optimal performance, the information is provided for reference to tennis coaches and players. The research objects were 12 tournaments participated by the Chan sisters from 2015 to 2018. Totally, there were 24 players in these matches. Video recordings of the matches were analyzed with expert input from national coaches. Each hit was labeled by design factors and levels using the "larger-the-better" (LTB) signal-to-noise ratio (S/N), as described in the Taguchi method of optimizing processes. Results indicated that the best winning strategy for the service game is for Yung-Jan Chan to be the server. The first serve lands in and close to the opposite receiver's location. Her partner in front of the net, Hao-Ching Chan, quickly finds the chance to poach towards the opponents' no-man's-land and score. Their best winning strategy for the receiver game is for Yung-Jan Chan to be the receiver who returns second service diagonally. Hao-Ching Chan then finds an opportunity to poach towards the opponent's body and score. This study concludes that the Chan sisters' position of competition model is for Yung-Jan Chan to stand on the baseline and Hao-Ching Chan to find the chance to poach. Yung-Jan Chan is mainly attacking, creating chances for Hao-Ching Chan to score points.
