柔道基本動作練習方式目前尚未有切確量化研究，因此本研究將就柔道「立姿摔法」的技術，透過運動學三度空間分析其發動至結束，包括不同位置「破勢」(Kuzushi)、「取位」(Tsukuri)和「施術」(Kake)的施技過程。受試者之取者(Toli Mono)與受者(Uke Mono)皆為國家代表隊選手（身高165 VS.172公分、63 VS.72公斤及30 VS.21歲），實驗時分別以10及20公分之距離，開始進行立姿摔法，其實驗採用3D影片分析法(Cinematography)，全程使用Panasonic (5100HS)攝影機二部，接續再以Peak Performance動作分析系統，分析動作流程參數等。研究結果得到20公分距離的取位期和施術期及全程動作所花費的時間都短於10公分距離，且20公分破勢距離的破勢起始到取位期結束及取位期結束到施術期結束的過程中，能使受者產生較多的位移變化，同時20公分多於10公分破勢起始到取位期結束及取位期結束到施術期結束受者重心速度的最高值。建議基本動作學習時，應採與對方保有20公分之距離，進行立姿摔法動作練習。
No quantitative studies were found in Judo basic skills. This studies investigated the skills of "Tachiwaza", through three-dimensional space kinematics, to analyze its whole changes from starting to ending, including the processes of Kuzushi, Tsukuri, and Kake. In this experiment, both the Tolimono and the Ukemono were national players (their respective height 165 & 172 cm, weight 63 & 72 kg, and age 30 &21). Take two distances (20-cm and 10-cm) to start the Tachiwaza. The experiment used Cinematography and two cameras Panasonic (5100 HS), and then analyzed the process parameter with the Peak performance motion analytic systems. The studied result is that 20-cm took less time in the ending time of Tsukuri and Kake period, and that 20-cm could make Ukemono produce greater displacement and changes in velocity than 10-cm from the Kuzushi's start to Tsukuri's finish and from the Tsukuri's finish to Kake's finish. At the same time, 20-cm distance that Kuzushi adopted would show greater changes in displacement. Suggest that when practicing basic skills, one should stay 20-cm distance far from the Ukemono to start Tachiwaza skills.
