碩士 === 中國文化大學 === 體育學系運動教練碩博士班 === 99 === This study aimed to explore the traditional method of horizontal table tennis grip (the R1 grip) and the new method of horizontal grip (the R2 grip) for eight national outstanding female table tennis players: which aimed for comparing the loop kinematic approaches of the ball-hitting speed for the angles of these two forehand- pull loop, and compared the stages of their kinematic parameters of the joints and limb segments. These eight contestants were averagely18.25 years and 160.5 cm and weighted 55.4kg. In this research, the EVA software adopted the trajectory phenomenon from the VAC software, used the SPSS for 6 Windows 11.0 software for statistical processing, and compared the differences between the above two kinematics parameters by the sample T-examination. The result showed that holding the R1 grip of batting swing distance from 0.36 ± 0.03 m was shorter than holding R2 grip sideways from 0.50 ± 0.03 m and reached the remarkable difference (P<.05), and that the R2 grip was faster than the R1 grip; secondly, holding the R1 grip when the bat hit the ball in an angle of 76.98 ± 3.00 was larger than holding the R2 grip when the bat hit the ball in an angle of 68.77 ± 0.92, had significant differences (P <.05), and revealed that the angle of holding the R2 grip on the ball loop pull was smaller than that of holding the R1 grip, increased the privacy of the ball, let the opponents feel it difficult to distinguish the direction and placement, and made the contestants more easily hit the ball; and thirdly, the ball of falling onto the other opponent’s table from the player holding the R1 grip : 0.252 ± 0.02 seconds and that from the player holding the R2 grip: 0.236 ± 0.02 seconds had significant differences (P <.05) and showed that the speed of the player by holding the R2 grip was faster and better than his holding the R1 grip. The above study of holding the faster and shorter R2 grip and its smaller angle, more privacy, and more power were very crucial to the technical performance of the table tennis and worth the promotion and the application.
