The purpose of this study was to investigate the characteristics of techniques used by Korean, Chinese, japanese elite male long jumpers in takeoff and flight phase and to provide the data for improving jumper's techniques and developing abilities. The subjects of this study were four finalists who participated in the Asian Games held in Pusan in 2002. Resulting kinematic data were obtained from seven jumps using three digital video cameras filmed at 60Hz. The conclusions were as follows; 1. At touchdown of the board it was efficient that the body angle was so small as -21° and the trunk was stood nearly upright. Because such movement made to minimize the loss in horizontal velocity during takeoff phase, and made to maximize the gain in vertical velocity at launch. 2. At the top of flight phase the trunk was leaned backward a little(about -12°) and was in balance by using the lower limbs. Therefore such movement made necessary preparations for landing even though jumpers used the hang style. 3. At touchdown of the board when jumpers made the trunk stand upright, the angle of inclination in trunk was smaller in flight phase. Hence for the stable landing jumpers should make the trunk stand nearly upright at touchdown of the board.
