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.

The purpose of this study was to quantify the contribution of body joints for take off of two-foot vertical jump performances with the increase of approach distance. Eight male taekwondo players volunteered to participate as subjects in two-foot vertical jump experiment with one-step, three-steps and five-steps approach distance. The take off phase of vertical jumps were filmed by using 16㎜ high speed camera and measured the ground reaction force by using the force platform simultaneously. At take off, a elapsed time of downward phase was shorter than that of push off, and also decreased the elapsed time of take off with the increase of approach distance. For the downward and push off phase at take off, the contribution of knee joint muscle group was increased significantly with the increase of the approach distance. However, the contribution of hip joint muscle group was decreased significantly with the increase of the approach distance relatively. The legs were the greatest contributors for two-foot vertical jump of each approach distance. The summation of the contributions derived from legs were about 90% for downward and push off phase, respectively. And the contribution of the hip joint was about 50%. The results of this study indicate that while the legs contribution with the increase of approach distance were similar among one-step, three-steps and five-steps, the contributions of each joints of the legs employed to achieve these results were notably different.

This study aims to establish a study model based on preceding studies about relationship quality and customer buying behavior according to Taekwondo gym relationship marketing execution and examining relations between relationship quality and buying purpose decision of Taekwondo gym executing relationship marketing to provide actual data required in managing Taekwondo gym. The target of study is a population of trainees' parents of Taekwondo gym in Daegu and Busan. Convenience sampling was used, and total of 351(87.8%) people's surveys were used as valid samples. As the result of reliability test of measurement tool, Cronbach's α was located between .633 and .821, which is appropriate for the purpose of study, and multiple regression was used for data analysis. The following results were obtained from this method. First, in the effect of relationship marketing execution factor on relationship quality, there was significant effect of customer orientation, response and flexibility on reliability and immersion. Second, in the effect of relationship marketing execution factor on buying purpose decision, there was significant effect of customer orientation, response and flexibility on buying intention and customer reliability. Third, in the effect of relationship quality on buying purpose decision, there was significant effect of reliability and immersion on buying intention and customer reliability. In generalization, relationship marketing execution of Taekwondo gym affects reliability and immersion of relationship quality of the gym and helps buying purpose decision of buyers. Therefore, relationship marketing execution of Taekwondo gym will help increasing the level of reliability and immersion of preexisting trainees and their parents, which will lead to buying purpose decision and Taekwondo gym will be under efficient management.
