| Summary: | 碩士 === 臺北巿立體育學院 === 運動技術研究所 === 97 === This paper is to probe into the kinematics parameters of Ta I O To Shi, directions (pushing outward and pulling inward) of two different Hike te and Kake, such as joint angle of limb, angular velocity and change of body barycenter curve in motion.
Research objects of this experiment are male players who were members of national team and specialize in Ta I O To Shi. Toli Mono is from three weight levels: light level (-66kg), mid-level (-81kg) and heavy level (+100kg) and other individuals (lighter weight, same weight and heavier weight) are as Uke Mono. Ten eagle digital video cameras (200HZ) are adopted to shoot and video is digitized by eagle digital system. Basic on all information got, we come to the following conclusions:
1. In the action of Hike te, the elbow joint angle and shoulder joint angle of inward pulling are smaller than those of outward pushing. For the angular velocities of elbow joint and shoulder joint at the weight of -66kg and -81kg, the angular velocity of heavier Uke Mono is smaller and imposed force may be greater.
2. In the action of Hike te, for the horizontal displacement of elbow joint
and shoulder joint at -66kg and -81kg, outward pushing, lighter wrestlers have smaller displacement; in the case of inward pulling, at the weight of -66kg, -88kg and +100kg, heavier wrestlers have larger displacement. Two different directions of Hike te largely vary with each other.
3. For the horizontal displacement of body barycenter in the case of different directions of Hike te, lighter wrestlers have smaller displacement and heavier wrestlers have larger displacement for outward pushing; wrestlers of same weight have smaller displacement and lighter wrestlers have larger displacement for inward pulling. The larger deviation of barycenter, the greater possibility of being thrown to the ground may be.
