摘　　要：北京奥运会首次使用新型游泳出发台,对其开展游泳出发技术分析可以帮助我国运动员尽快适应该设备。采用高速摄影和图像解析法对16名男子大学生游泳运动员在2种台板上完成蹲踞式出发技术进行运动学研究。结果表明:新型出发台后摆蹲踞式预备姿势的稳定性高,利于腿部发力;2种台面后摆蹲踞式出发技术的离台角、入水角、离台和入水重心均无明显差异;新型出发台离台水平速度较大,同传统台面比较新型出发台出发后水下滑行至10m段的时间有绝对优势,能够更加充分发挥蹲踞式出发技术的优越性。The new starting platform was used for the first time in Beijing Olympic Games, and the devel- opment of swimming starting technical analysis can help our athletes to suit equipment as soon as possi- ble. By using the high--speed photography and image analysis method, 16 male college student--swim- mers complete the crouch start technique from two different starting platforms and kinematic research is made. The result shows that the backward crouch start from new starting platform has higher stability and shorter departing time, which is in favor of quick start. There is no significant difference among the angles of departing platform, entering water and gravity center when departing platform and entering wa- ter. The horizontal speed from new starting platform is high. Considering the time spent in 10 meters gli- ding underwater, backward crouch start on new starting platform has absolute superiority. These results suggest that new starting platform can give a full play to the superiority of starting technique of crouch start.
