文献中介绍的女子400米全程跑“按比例分配”的方法是不完全的。这里起决定作用的是:全程栏间的总步数或者怎样运用每个栏间的节奏。从获得的材料看,应当是这样的: (1)改变节奏的女运动员,以15步节奏极快地跑完前半程。然而,在改变节奏以后的第一个栏间,速度急剧下降。这时栏间节奏由15步过渡到16步,最后过渡到17步。这样能够更从容不迫地调整速度和栏间技术。显然,在改变节奏时如何保持速度,对变换节奏的女运动员是至关重要的。
Women’s 400 meters described in the literature throughout the “proportional distribution” method is not complete. Here is the decisive role: the total number of steps across the column or how to use the rhythm of each bar. From the material obtained, it should look like this: (1) Changing the rhythm of a female athlete, running the first half of the pace extremely fast in 15-steps. However, the speed dropped sharply during the first period after changing the rhythm. At this moment, the tempo of the bar transitions from 15 steps to 16 steps and finally to 17 steps. This will make it easier to adjust speed and bar technology. Obviously, how to keep pace while changing the tempo is crucial to changing the rhythm of a female athlete.
