バドミントンのスマッシュ動作におけるラケットの影響

抄録

The purpose of this study was to analyze the influence of racket on human motion in badminton smash motion. To analyze it, we made an experiment using three badminton rackets. The smashes of 14 males were selected for the analysis, and were digitized. Performances were recorded by twelve motion capture cameras. In this study, we analyzed a position in the vertical direction of each marker and angle of joints and considered a characteristic of the smash motion at the time of using each rackets. The results showed that there were characteristics of the smash motion, such as opening the elbow at the time of take-back, turning the wrist and a difference in timing of raising up the badminton rackets. Moreover, it proved that their characteristics differed by the motion experience and skill. And we calculated a standard deviation to analyze a difference in the motion between using the rackets. As a result of this analysis, a difference in dispersion of the smash motion was observed depending on using the rackets by the standard deviation. In addition, some inexperience persons could be close to motions of experience by changing the rackets. Therefore, the result showed that it was very important to select a racket suitable for them.
