本研究目的為分析參加2011年台北青少年桌球公開賽優秀青年選手三段技術表現，以桌球比賽綜合技術記錄表格為研究工具，記錄單打前八強比賽中選手每一回合球的最後擊球技術得、失分，並將各項資料以描述統計進行得分率及使用率統計，運用三段技術評估法對選手做技術表現情形分析診斷與評估，並探討青年選手單打具得分預測力的技術。所得結論如下：一、接發球搶攻段在三段技術中得分率都達良好以上、使用率也都有較高的表現，顯示接發球搶攻段是現階段優秀青年選手主要的得分技術，也是最具得分預測力的技術。二、八位選手相持段得分率皆不及格、使用率也偏低，是共通較弱的技術。三、所有選手相持段得分率皆不及格情況下，東勇渡選手得分率仍高居其他選手，顯示相持段技術的表現將是影響比賽勝負重要關鍵因素之一。
