摘要

目的：本文探討臺灣好手曾俊欣在2018年三大賽的各技術因子影響比賽勝負之關聯程度。方法：研究對象為曾俊欣及其17位對戰選手，共計18場39盤及9個變項，資料採用LabView程式語言軟體進行灰色關聯度分析。結果：在澳網各技術因子之關聯度前三高依序為：第一發贏球率、接發球點勝率及第二發贏球率，最低為非受迫性失誤；在法網前三高為：接發球點勝率，第一發贏球率及第一發進球率，最低為ACE球數；在溫網前三高則為：第一發進球率、第一發贏球率及接發球點勝率，最低為ACE球數。結論：曾俊欣在草地與硬地場地比賽時，第一發球時的表現對最後勝負影響最大；而在較慢球速的紅土球場比賽時，接發球的表現是影響勝負的重要因素，另外在ACE球方面，在三大賽事皆對勝負影響較小。最後建議，教練應加強選手發球後的第二拍擊球質量，另將接發球列為重要訓練課程。

Purpose: This study is aimed to discover the facts which affected Chun Hsin Tseng's performances in three different Grand Slam tournaments in 2018. Methods: This case study is focussed on Chun Hsin Tseng and his seventeen opponents, including eighteen matches, thirty-nine sets and nine variables. The analysis and statistics are based on a programming language software based on Grey Relational Analysis. Results: The top three correlated technical factors at the Australian Open are listed below in sequence: Rating of winning first serves, service returns and rating of winning second serves. The lowest rated factor is unforced errors. The top three correlated technical factors in the French Open are service returns, first serve winners and first serves in, the lowest rate is for the ACE. The top three correlated technical factors in Wimbledon are first serves in, first serve winners and service return winners, the lowest rate is for the ACE. Conclusion: The results indicate that Chun Hsin Tseng's first serve is the key factor to win on grass or hard courts. However, the performance of service returns can be the key factor to win on clay courts where the ball travels slower. Moreover, the least effective factor for overall games is the rate of ACE. In conclusion, the coach should strengthen the player's ability to follow up the serve and priorities the return of serve as an important part of the training program.
