| Summary: | 碩士 === 國立臺灣師範大學 === 體育學系 === 103 === The purpose of this study was to investigate the grip force of the badminton players when they were performed forehand net kill technique. Eight college elite badminton players served as the participants in this study. The palm pressure sensors (Tekscan Grip 4255N) were pasted on the fingers and the palm, Tekscan software was used to collect finger grip force. A Wilcoxon matched-pairs signed-rank nonparametric statistical test was conducted to compare the differences between every two spots in the hands. The results showed there were significant differences in the duration time of the movements with each other. The shortest duration time was the swing phase in the movement (0.07sec), followed by the lift the racket, third for the preparation period, the longest period to follow. The max force of middle finger, index finger, little finger, the second to fourth metacarpal, ring finger and the first metacarpal were generated in the swing phase before impact. In the whole action process, the middle finger, index finger, ring finger and little finger played an important role in controlling force and stabilizing racket. Since the racket compression during the movement, the maximum force was generated after the impact in the fifth metacarpal. Also at the following phase, each knuckle generated the second peak force in order to stabilize the racket.
