The motions of elite female setters in the world who are setting in official games were recorded on video by three VTR cameras, and three-dimensional motion analysis was conducted. In this study, the setting technique to set to the accurate position that was easy for attackers to spike was focused on. The movement to the level point of the received ball and the ball-handling motion which were important to succeed the set were analyzed. That is because carrying on these motional processes in success becomes the accurately set to the accurate position. In order to arrange and investigate quantitatively the set position and direction which are played at various positions on the court, the operation programs of the various measurement items made by myself were created, and the data was analyzed. By extracting the motion which is inherent in common or overall pattern from motions of analyzed elite setters and explaining it biomechanically, the technique characteristics to set to the accurate position was clarified. The results were as follows. The analysis attempts were the setting motions to set to the accurate position and direction. In movement to the level point of the received ball, the center of gravity became the lowest from the time of the highest value of the received ball at an average of 24±6％ of the time, and it was jumped toward the position which caught the ball. In ball-handling motion, the posture was prepared before impact, right and left hand were mostly drawn for both hands in front of forehead. Both arms were extended to the set direction symmetrically, and the ball was released. These knowledge is the motional processes (technique) which may be generalized to the others and which can be metastasized, and these are considered to contribute valuable scientific data at the time of mastering setting technique in sports instruction.
