一九八一年七月二十一日,在科罗拉多斯普林斯,我们曾对八名男短跑选手的技术影片进行了分析。我们摄录了各受测人的两次起跑动作,片速为100格/秒。途中跑是在受测人跑至50——60码间,用160格/秒的片速摄录的.本文中各空间/时间的原始数据,全由实录影片求出。起跑中的距离、时间参数是选用两次摄影记录中的较优者。为精确反映较好的一次起跑和50——60码间的途中跑中各动作的实际情况,我们复印了有关影片,并注上了标记和数值,如图1——8。
On July 21, 1981, in Colorado Springs, we analyzed the technical films of eight male sprinters. We recorded each tested person’s two start-up action, film speed of 100 cells / second. Run on the way in the test run to 50 - 60 yards, with 160 grid / second film speed recording in this article, the space / time of the original data, all obtained by the recorded video. Starting distance, the time parameter is the best selection of two photographic records. In order to accurately reflect the better first run and 50 - 60 yards on the way running the actual situation, we photocopied the film, and marked on the mark and value, as shown in Figure 1--8.
