國內優秀男子網球選手單打發球對比賽勝負關係之研究

The Effects of Serves on Elite Single Male Tennis Game Results in Taiwan

本研究目的在探討國內優秀男子網球選手單打發球對比賽勝負關係之情形。本研究係針對2002年六月在台北市立網球場所舉辦之第一屆中油盃全國網球排名賽，以大會男子網球選手前十六強為對象。觀察工具是以攝影機全程拍攝選手比賽之結果，所使用之資料分析方法包括：採用描述性統計、t檢定及皮爾森積差相關分析法等，各種顯著水準的認定，均以α值＝.05才達顯著水準。研究所獲結論如下：獲勝選手在第一發球贏球率、第二發球贏球率、發球局成功率、ACE球、破發球點扳回率及總得分數之間達顯著水準（p＜.05）獲勝選手明顯優於落敗選手，因此，網球發球的成功是需要仰賴多方的技術支援與發揮下才能實現，而能保住發球局，才是奠定勝利成功的不二法門，同時現今唯有全面的技術才能克服不同的比賽情境與贏得比賽的勝利。選手在網球發球技術因子對總得分關係上，第一發球贏球數、第二發球贏球數、發球局成功率及ACE球因子對總得分數達顯著水準（p＜.05），兩者關係成正相關，因此，比賽能保住發球局不但佔有優勢的地位也會主導比賽的勝利，而比賽中若能適時的發揮ACE球的數量，不但可直接保住發球局對比賽的勝利也會有正向的作用。The purpose of this research is to examine and discuss the characteristics of the serves of elite male tennis players during singles competition. The top sixteen single players of the CPC Tennis Competition in the Taipei were observed using cameras and examined their serving performance.

Nowadays tennis player who excels at every aspect of playing tennis could face any games situation and achieve a complete triumph. Next, as for the relationship between the first serve point, second serve point, percentage of valid serve, and ACE , the four causes are proportional.
