Keywords: mode, archery, kinematic feature, training, digital filtering, technical level
AbstractINTRODUCTION: Archery is an ancient sport. In recent years, the development of archery in China has been quite rapid. The performence of this sport in Shan Dong has also rapidly increased, but it is rare for archers` techniques to be quantitatively analyzed. Therefore the movement strcture, kinematic features and influence on the performence of 6 archers on the Shan Dong team were comprehensively compared and analyzed in order to raise their technical level .The best movement techniques were found and combined in the most suitable mode of these six archers. According to this mode, their techniques were improved individually in training .The more rational movement techniques were performed, followed by an exploration of new ways of scientific training in archery. METHODS: Thirty-six arrow shots of these six archers of the Shan Dong team were analyzed, and the data were processed by the more advanced video analysis system - Bewegungs Analysis System: Pentium 586 computer; 21inch SAMSUNG advanced color monitor (1024%1024); Panasonic Video Cassette Recorder (AG- 7355); the video tape was recorded with time code; the software program to be provided by Germany. The interval between the frames was 0.02 second. The digital filtering method was used for data smothing and a cutoff frequenty of 3 hz was adopted. In measuring, x axis: the direction perpendicular to the target; y axis: the direction perpendicular to the horizontal plane; z axis: the direction of paralleling the target. RESULTS: 1. A comparison and analysis of six archers in each phase period 1.1 The average time for an arrow to be shot by each varies greatly (from 4.812s to 10.956s). The average time for an arrow to be shot by the same archer is relatively stable. The movement rhythm of the six archers is not the same. 1.2 The shooting time of arrows hitting the ten-point ring is ordinarily from 4.78s to 7.84s, and the aiming time is from 2.46s to 5.60s.The shooting time of arrows hitting the eight-point ring is under 4.32s, and the aiming time is under 2.24s. 2. A comparison and analysis of the kinematic features of these six archers was made. CONCLUSION AND SUGGESTION: 1.The movement rhythm of Li Changjun, Tang Huan and Zhu Maodong is relatively fast, The movement rhythm of Xin Lei and Li Ming is relatively slow. The movement techniques of Li Meng and Zhu Maodong in forcing to release period are a bit similar. The movement techniques of Xin Lei and Sun Wei in forcing to release period are a bit similar. 2. The best movement techniques of each can be combined in the most suitable mode to train the archers. 3. In training, the movement technique of some of the archers should be improved with rational technique features. REFERENCES: Jiang Qian et al. (1993). A Study of Elite Chinese Archers’ Aiming Skills.
