英文摘要 | This paper studied the relation between the aiming trajectory, which was within the 1.5 second aiming time interval counted before the releasing instance, and the corresponding target location. In this study, a world-class archer, with the height 170 cm, and weight 68kg. who won the silver medal of 2004 Olympic Athens, participated in this research. Four rounds with three arrows for each round are conducted in the range of 70 meters, with a total shot of twelve arrows. To record the aiming trajectory, a laser pen was mounted on the bow. Meanwhile, two JVC digital video cameras were located in front of the archer and the target for capturing the archer's aiming trajectory and the target coordinates respectively. Based on the captured data, the APAS (Ariel Performance Analysis System) motion analysis system was used to obtain the vertical and horizontal target coordinates, which were further used to analyze the correlations between the aiming trajectory and the target location along the horizontal (X) and vertical (Y) respectively. The mean of the aiming trajectories of the total twelve shots was analyzed along the vertical and horizontal directions for discussing his aiming stability. Results of this research are as follows. First, the subject's his aiming trajectory tends to be stable during the last second before the releasing. Moreover, the closer the time to the releasing instance, the more stable the aiming trajectory. Second, his aiming trajectory is approached from the upper right to the releasing point. Third, the correlation between the releasing point along the vertical and horizontal directions is negative, and it has reached the significant level (p<0.05). The correlation between his releasing point and the shooting points on the target along the vertical direction is positive, but it is negative along the horizontal direction. However, these two correlations have not reached the significant level (p>0.05). |
