網球反手拍不同持拍法對擊著地球技能之分析

本研究係以本校興趣選項網球組男女學生為受試者，設計了對牆擊球與對發球機擊球兩種練習方法，對受試者的反手拍擊球做測驗，以擊球能力表現及進球率來代表反手拍測驗結果。研究動機與目的在瞭解初學者重視正確的握拍法與認清較好的握拍法來學習反手拍擊球技能，做為日後教學、訓練上之參考。依據統計分析結果加以討論後，茲摘錄具體結論如下：一、單、雙手反拍對牆擊球成績方面：女生組以雙手反拍表現最佳，男生組則以單手反拍表現最佳。在長距離擊球表現上，男女組無顯著差異，但在短距離擊球表現上，女生組在雙手反拍表現優於男生組，具顯著差異(p＜.05)。顯示女性初學者較適合雙手持反拍擊球。二、單、雙手反拍對發球機擊球進球率方面：單手反拍長距離擊球表現上，男生組優於女生組無顯著差異。雙手反拍長距離擊球上，男生組優於女生組，具顯著差異(p＜.05)。在短距離擊球上，女生組優於男生組，則無顯著差異。三、單、雙手反拍學習效果方面：男女組在不同長、短距離位置經過練習後，其末測的成績表現均具顯著差異(p＜.05)，顯示各組經練習後有明顯學習效果。在整體表現上男生組以單手反拍較易控球，其學習效果較雙手反拍為優，女生組以雙手反拍較有力道控球，其學習效果則較單手反拍為佳。四、單、雙手反拍在不同距離位置擊球能力方面：單、雙手反拍於相同距離擊球能力上，男子組 F=0.16，女子組 F=2.52，無統計上的顯著差異。但在不同長、短距離位置擊球能力，男子組 F=1.61，女子組 F=2.50，整體表現上短距離擊球優於長距離，具顯著差異(p＜.05)，顯示初學者應先從短距離位置學習擊球後，再從長距離位置練習，其學習效果可更佳。

The study aimes to examine if certain grips are able to provide an easier access to a better backhand stroke skill for tennis beginners. The subjects are students who have chosen tennis for their weekly Physical Education classes. Their performance is asessed and record when practicing backhand ground stroke with a serving maching and against the wall. The following are results and conclusions: 1.Practicing against the wall --- (1)Female students with two-hand backhand performs better, and male students with one-hand back hand performs better. (2) For long distance stroke, there is no significant difference between male and female students. For short distance two-hand backhand stroke, female students are better (P＜.05). the final Female students with two-hand backhand ground stroke performs better。 2.Practicing with a searving maching--- (1) For long distance one-hand backhand stroke, male students are better, but with no significant difference.(2) For long distance two-hand backhand stroke , male students are better with significant difference(P＜0.5).(3) For short distance stroke, female students are better with no significant difference. 3.Learning effectiveness--- For both male and female students, the final tests show significant difference in their performance: male students one-hand better two-hand in their performance students two-hand better one-hand in their performance。 4.Backhand stroke from different positions--- (1)There is no significant difference between one-hand and two-hand stroke from different positions ( F=0.16 for female, F=2.52 for male). (2)Short distance stroke is better than long distance stroke with significant difference (P＜.05, F=49.36 for male, F=53.14 for female).
