The purpose of this study was to determine the selected biomechanical characteristics of the techniques used by elite male and female long jumpers during the transition from approach to takeoff in the long jump. The subjects were the 18 finalists in the men`s long jump and women`s long jump at the 73rd national sports games in daegu. The last two strides from long jumps on an outdoor track were filmed with two 16mm him speed cameras (Photosonics Co.) operating at a nominal rate of 100 frams per second. The means of the horizontal touchdown distance for the jump were greater than for the preceding stride for the males and females. The elite male and female long jumpers made a small increase in the horizontal touchdown distance for the last stride, and a large increase in that for the jump. Significant of differences between the males and females were found for the horizontal takeoff distance of the last stride and the jump. Analysis of the data comparing the long jumping techniques of the elite male and female long jumpers revealed significant differences in all aspects of the horizontal velocity. The height differences between the males and females of the center of gravity of touchdown, mid-support and takeoff for the support phase of the last stride were narrowed to those for the preceding support phase. The height differences between the males and females of the center of gravity of touchdown and mid-support for the support phase of the jump were more narrowed than those for the preceding support phase, The stride frequency of the elite long jumpers were increased during the last stride of the approach.
