中文摘要 | 目的:探討國際青少年男子選手在網球四大公開賽之各攻守技術因子對比賽勝負的影響,並分析勝方選手在四大公開賽各項技術因子的比較。方法:本研究對象為晉級2012年網球四大公開賽青少年組男單16強選手共41名。統計方法採用獨立樣本t檢定及單因子變異數分析,顯著水準設定為α = .05。結果:一、在2012澳網中,ACE球數、第二發球贏球率及致勝球等因子,獲勝選手比落敗選手表現較佳(2顆,15.5%,5.8個;p < .05);在2012法網中,雙發失誤、非受迫性失誤及接發球點勝率等因子,獲勝選手比落敗選手表現較佳(-1.3個,-3.2次,13.2%;p < .05);在2012溫網中,第二發球贏球率因子,獲勝選手比落敗選手表現較佳(15.3%;p < .05);在2012美網中,第一發進球率、ACE球數、第二發球贏球率及致勝球等因子,獲勝選手比落敗選手表現較佳(12.5%,1.7顆,16.8%,5.8個;p < .05)。二、獲勝選手之三種技術因子在四大公開賽有差異,在非受迫性失誤每場次數依序為溫網、法網及澳網;在致勝球在每場表現依序為溫網、美網及澳網;而在第二發球贏球率(%)的表現依序為溫網、美網、法網及澳網。結論:經分析四大公開賽之各攻守技術因子對比賽勝負的影響發現,青少年選手在(美、澳網)硬地及(溫網)草地球場比賽時,在第二發球的發揮成為獲勝的關鍵,而在(法網)紅土球場雙發失誤及非受迫性失誤明顯影響比賽勝負,因此,減少發球失誤與提升擊球的穩定性是贏球的重點。 |

The study adopted Independent t test and one-way ANOVA as the statistical method. The remarkable standard established (α = .05). Result: First, Australian Open, the factors were Aces, the percentage of second-serve points won and winners. The winner's performance was better than the loser's (2, 15.5%, 5.8; p < .05); France Open, the factors were double faults, unforced errors and total return points won. The winner's performance was better than the loser's (-1.3, -3.2, 13.2%; p < .05); Wimbledon Championship, the factor is the percentage of second-serve points won. The winner's performance was better than the loser's (15.3%; p < .05); US Open, the factors were the percentage of first-serve points won, Aces, the percentage of second-serve points won and winners. The winner's performance was better than the loser's (12.5%, 1.7, 16.8%, 5.8; p < .05). Second, the winners' three technique factors in Four Tennis Opens have differences. The unforced errors per game are in the order as Wimbledon Championship, France Open, and Australian Open. The performances of winners in each game are in the order as Wimbledon Championship, US Open, and Australian Open. The performances of the second serve winning percentage are in the order as Wimbledon Championship, US Open, France Open, and Australian Open. Conclusion: Though the analysis of the effect of the offence and defense technique factors on Four Tennis Opens outcomes, the study discovered that the development of the second-serve was the key to victory when junior tennis players match in hard court (US Open, Australian Open) and grass court (Wimbledon Championship). Double faults and unforced errors in clay court (France Open) obviously affected the success and the failure of the competition.
