本研究旨在研究2009年世界女排大獎中，不同的發球方式、落點、位置對發球結果的影響。本研究對象為2009年世界女排大獎賽台灣苗栗站四隊，參賽隊伍分別為荷蘭、德國、美國、多明尼加等四隊，各採用發球方式均為跳躍發球跟固定站立發球（德國隊只有跳躍發球的方式並無固定站立發球），並由筆者親赴現場攝錄每場比賽之過程，攝錄之影帶經由投影機播放觀看後，將四隊發球方式、落點、位置之數據，經由統計分析後，發現四隊的發球方式、落點、位置並未達顯著性差異，這個結果顯現出，世界級的球隊在發球技術上，已有著一定程度的高水準表現，可見能擠身在世界級比賽的球隊 ，不只是發球技術要好，在防守、攻擊、攔網等技術上也需要有良好的表現，方能使其水準更上一層樓。

　　This thesis mainly studies how different serving styles, placements, and locations affect serving results. The targets of this thesis are four competitive volleyball teams of FIVB 2009 Women’s Volleyball Grand Prix Taiwan Miao-li- Netherlands, Germany, USA, and Dominican Republic. These volleyball teams all adopted both jumping and fixed stand servings except Germany. German Team used only jumping serving but not fixed stand serving. By analyzing the data of serving styles, placements, and locations from these four teams, we found that there is no obvious difference among them. The present results show that world-class teams have high standard performances in serving technologies. We can clearly know that the teams, which can be called world-class teams, own not only great serving technologies but also great defensive, denunciative and blocking technologies so that they can perform better and better.
