有的跳远运动员在倒数4～8步内设一个第二标志,以检验前半程助跑的准确性。 实践中跑到第二标志处一般有以下四种情况: 一、误差较大,运动员试图骤然停住重新助跑。但有经验的人都知道,跳远不像跳高,它的助跑速度在最后10米内达到了个人最高速度的95％～98％,在如此高速的情况下想几步内刹住脚不超过踏跳板及其延长线几乎是不可能的。这就意味着试跳将失败。第二标志本身难以挽救前程助跑的不准确。即使有的运动员最后5、6步停住了,还得顶住心理压力与时间限制重设步点,重新试跳。
Some long jump athletes in the countdown 4 to 8 steps to set a second mark to test the accuracy of the first half run. Run to the second sign in practice generally have the following four conditions: First, the error is larger, the athlete trying to suddenly stop run again. But experienced people know that long jump does not like high jump, and its run speed in the last 10 meters to reach 95% to 98% of the personal maximum speed, in such a case of high speed to brake the foot does not exceed the pedal And its extension is almost impossible. This means that the test jump will fail. The second sign itself is difficult to save the inaugural run inaccurate. Even if some athletes stopped at the last 5,6 steps, have to withstand the psychological pressure and time limit to reset the pace, try again.
