采用运动生物力学手段对我国高水平游泳运动员的出发技术进行诊断,通过分析研究,找出了运动员在出发过程中所存在的技术问题。为帮助运动员提高出发技术,研究者发明了一种可以显示出运动员从发令枪响到脚离台所用时间的电子台上时间测试仪。通过采用该仪器帮助运动员训练出发技术,所有运动员的出发10米段时间都减少了:减少的平均时间男子为0.48秒,女子为0.62秒(P<0.01),最大值为0.83秒。 By means of sports biomechanics, the starting technique of our country ’s top level swimmers is diagnosed. Through the analysis and research, the technical problems existing in the starting process of the athletes are found out. To help athletes improve their starting skills, the researchers invented an electronic time-of-flight tester that showed how long it took for an athlete to fire a gun to his feet. By using this instrument to help athletes train their starting technique, all athletes reduced their 10-meter starting time by a factor of 0.48 seconds for men and 0.62 seconds for women (P <0.01), with a maximum of 0.83 seconds.
