摘要

前言：在2011年表現最突出的表現人物Novak Djokovic（喬柯維奇）在硬地球場上連續獲勝Roger Federer四次的選手，並在2011年登上世界第一的選手。目的：主要探討Djokovic在2011年與2010年在發球局、接發球局、保發球局、破發球局及關鍵分表現比較各階段得分比較研究。方法：觀看統計2010年與2011年兩年Djokovic對戰Federer在硬地的比賽，以分析兩年對戰在發球局與接發球局各階段得分比較研究。結果：（一）、在發球直接得分率從2010年22%增加到2011年29%有很明顯的提升：Federer在前三拍失分從26%增加到24%。（二）、在接發球局Djokovic回擊帶入對抽由2010年16%增加到了2011年24%：Federer接發失誤從29%增加到34%。（三）、Djokovic保發球局平均發球直接得分1分到2011年提升到1.3分，Federer保發球局平均發球直接得分2010年1.2分到2011年下滑到1.3分。（四）、Djokovic發球面臨破發點時發球直接得分在2010年2到2011年增加到9，Djokovic接發球面臨破發點時降低回擊失誤的方式來增加回擊成功率。結論：（一）、頂尖選手對戰中發球直接得分占了很大勝負關鍵，贏球要有更強勢更精準的發球，讓發球後減少接拍次數與增加成功率。（二）、接發球要有能持續回擊對方發球的能力，不僅是提升回擊成功率還要增加回擊時候的效果，讓對手無發在發球後容易搶到優勢。（三）、Djokovic在面對Federer時每局的發球直接得分有1分才能保住發球局， Federer在面對Djokovic時每局的發球直接得分有1.2分才能保住發球局。
