Thirteen elite collegiate male table tennis players were recruited in this study. All the movements were recorded during the backhand fast loop drive. The data were analyzed by Vicon Motion Analysis System to gather the information on the kinematic parameters from the movements of the trunk and upper limb. By using Pearson’s correlations to investigate the relationship between ball velocity and kinematic parameters. The results found the order of the highest angular velocity of the body segments during acceleration phase were consistent to the principle of kinetic chain. Moreover, results also indicated that higher ball velocity can be achieved by decreasing the range of motion of shoulder internal-external rotation during backhand drive, also by increasing range of motion of shoulder flexion during the acceleration phase, and followed by decreasing the angle of shoulder abduction at impact. By adjusting the proper body movement and getting a faster swing, may help the player to reach his/her highest ball velocity during backhand drive.目　次 第壹章　緒論………………………………………………………1 　第一節　研究背景………………………………………………1 　第二節　研究目的………………………………………………4 　第三節　研究範圍………………………………………………5 　第四節　研究限制………………………………………………5 　第五節　名詞解釋與操作性定義………………………………6 第貳章　文獻探討…………………………………………………13 　第一節　反手拉球動作技術……………………………………13 　第二節　桌球擊球動作之相關研究……………………………17 　第三節　影響擊球球速之關鍵動作……………………………20 　第四節　總結……………………………………………………24 第參章　研究方法與步驟…………………………………………26 　第一節　研究對象………………………………………………26 　第二節　實驗時間與地點………………………………………28 　第三節　實驗儀器與設備………………………………………28 　第四節　實驗場地佈置…………………………………………30 　第五節　實驗步驟與流程………………………………………32 　第六節　資料處理與分析………………………………………37 第肆章　結果………………………………………………………39 　第一節　桌球球速與動作時間參數……………………………39 　第二節　關節動作之角度………………………………………41 　第三節　關節動作之活動範圍…………………………………57 　第四節　關節動作之角速度……………………………………61 　第五節　關節動作之最大角速度………………………………76 　第六節　影響球速之關鍵運動學參數…………………………79 第伍章　討論………………………………………………………83 　第一節　反手拉球的動作時間…………………………………83 　第二節　軀幹與上肢各關節動作特徵…………………………85 　第三節　關節最大角速度出現時機……………………………92 　第四節　影響球速之關鍵運動學參數…………………………94 第陸章　結論與建議………………………………………………98 　第一節　結論……………………………………………………98 　第二節　建議……………………………………………………991025875 bytesapplication/pdf前衝弧圈球;動力鏈;球速fast loop drive;kinetic chain;ball velocitythesis
