摘要

目的：探討納達爾在法、美網之各項技術因子對勝負的影響，並分析發球及接發球與各項技術因子之間的關聯性。方法：研究對象為納達爾及其對戰選手，統計方法採用獨立樣本t檢定及皮爾森積差相關分析法，顯著水準設定為α＝.05。結果：納達爾在法網，第一發進球率、第一發贏球率、接發球點勝率、破發成功率、網前得分率、非受迫性失誤、雙發失誤比落敗選手表現較佳；而第一發贏球率與非受迫性失誤為負相關、第一發進球率與第二發贏球率為負相關、雙發失誤與致勝球為正相關、接發球點勝率與網前得分率為正相關；在美網，第一發進球率、第一發贏球率、第二發贏球率、接發球點勝率、破發成功率、網前得分率、非受迫性失誤、雙發失誤、致勝球比落敗選手表現較佳，而第一發進球率對ACE球、致勝球為正相關、ACE球與致勝球為正相關、第一發贏球率與網前得分率為正相關、接發球點勝率與致勝球為負相關，也與非受迫性失誤為負相關、致勝球與非受迫性失誤為正相關；另外，在美網的網前表現優於法網。結論：納達爾的發球以落點為主，並多以閃身正手拍採取攻擊，接發球站位離底線後方較深區域以求擊球的準確度，其第一發球的表現對其他各技術層面最具關聯性。

Purpose: The study was to examine the effects of the technique factors that Rafael Nadal used in 2013 France Open and US Open and to analyze the connection among serve, service return, and other technique factors. Methods: Research subjects were Nadal and his competitors. Independent t-test and Pearson product-moment correlation were utilized as the statistical method. The remarkable standard established as (α = .05). Result: In French Open, Nadal's performance was better than other losers’ on first-serve percentage, first-serve points won, receiving points won, break point conversions, net point, unforced errors, and double faults. However, a negative correlation was found between first-serve points won and unforced errors and between first-serve percentage and second-serve points won. On the other hand, a positive correlation existed between double faults and winners and between receiving points won and net points won. In US Open, Nadal showed excellent performances on the percentage of first-serve points won, first-serve points won, second-serve points won, receiving points won, break point conversions, net point, unforced errors, double faults, and winners. There was a positive connection between following techniques: first-serve percentage and ace and winners; ace and winners; first-serve points won and net points won; winners and unforced errors. However, negative correlation was also found between receiving points won and winners and between receiving points and unforced errors. In general, Nadal's performance on net play in US Open was better than in French Open. Conclusion: Nadal's serve emphasizes on the placement point. He used dodge and forehand as attacks. To pursue higher accuracy of stroke, he stood at the area behind the base line. Finally, the study showed strong connection between his performance on the first serve and other aspects of techniques.
