目的：本論文在比較9~12歲優秀桌球兒童與一般兒童在運動協調能力之特性。方法：本研究對象為優秀桌球兒童101名，為本研究實驗組，一般兒童1365名，為本研究對照組；兩組兒童皆為9~12歲兒童。兩組兒童皆須接受Movement ABC test與TMA test兩項測驗工具。結果：研究結果顯示，接受Movement ABC test與TMA test兩項測驗工具測試的兩組兒童，在運動能力總分都是達顯著差異的；優秀桌球兒童的運動協調能力確實比一般兒童還要好，尤其在球類技巧、平衡能力、動作能力總分以及視覺能力皆達顯著差異。結論：優秀桌球兒童在受過桌球運動訓練後，在球類技巧、視覺動作整合以及整體動作協調能力皆比一般兒童佳；在優秀桌球男、女童方面，則因年齡越大以及運動訓練越長的關係，而有較佳的動作能力。

　　Purpose: Compare the differences of the motor ability between elite young table tennis players and typically developing children. Method: Participants comprised of 101 elite table tennis players in the table tennis（TT）group, and 1365 typically developing children in the control group who were 9~12 years old. Result: The result showed that the typically developing children and the elite table tennis players had significant differences of their coordination ability in the Movement ABC test and TMA test. The elite table tennis players demonstrated better abilities than typically developing children, especially in ball skills, vision-motor ability and physical skills score. Conclusion: The elite table tennis players were considerably more coordination than the typically developing children. This was because of the age and the table tennis training the elite table tennis players undertook. They excelled in ball skills and visual-motor integrity.
