本研究係以本校男子網球隊員九名為受試者，平均年齡為22.8歲，所有的受議者均為志願參加。設計了左右各5個發球測驗位置，對球員的第一、第二發球做測驗，以成功率來代表球員發球測驗結果。研究動機與目的在瞭解本校男子網球員在各個發球位置的發球成功率差異，做為日後比賽訓練之參考。 本研究以成功率為衡量發球能力之依據，經相依樣本平均數理論檢驗，依據統計結果存在顯著差異時，再採取事後比較加分析比較後，茲摘錄具體結論如下： (一)受試群在離中央標誌右側2M處的第一發之發球成功率最高，該位置和離中央標誌1M及3M處的發球位置達明顯差異，其它各測驗位置相較，不具顯著差異。 (二)本校球員在左右側發球時以離中央標誌2M處的成功率最高，也是球員最佳的慣常第一發球位置。 (三)離中央標誌右側3M處是受試者第二發球益成功率較差的位置外，其他位置都沒有明顯差別。 (四)除了離中央標誌2M及3M處的發球總成功率達到顯著差異外，其它測驗位直的成功率並沒有明顯的差異。 (五)離中央標誌左側1M及2M處總發球成功率的平均成績達顯著差異，其他各位置都沒有明顯的差異。

This study is based on this School Men’s Representative Team in Total of 9 Players who have received testing, The mean age of the subjects was 22.8 years; there are 5 left/right various testing position designed for the Pective are Presentives as for the player’s ball serving for the volleys tested with the successive rate representing the player’s ball serving test result. As the study motive and purpose are to understand this school’s men’s tennis players in the various ball serving successive rate to be used at the future training reference. This study is based on the measurement of the ball serving ability of this successive rate through the average numeric evaluating analysis in aclcor dance with the analytic result for the discussion basis; here with is abstracted with the practical result as follows: (1) The part the group tested on the right side 2 meters away from the central mark that the first time ball serving successive rate is the highest. As for the positions 1 meter or 3 meters away from the central mark are apparently with the difference and as in comparing with other testing positions without the significant difference. (2) As this school players are serving on the left side those who are 2 meters away from the central mark with the highest successive rate this result is similar the those who are tested serving on the right side. (3) Except those who are tested on the right side 3 meters away from the central mark the second time of ball serving as for the other positions are with the successive rate without any significant difference. (4) Except those who are tested As for the positions 2 meter or 3 meter a way for the central mark the Total of serving as for the successive rate are apparently with the difference and in comparing with other testing positions with out the significant difference. (5) On the left side those who are 1 meter or 2 meters the Total of serving as for the successive rate the final test6s show significant difference the other tests positions without the significant difference.
