跳远起跳阶段水平速度的损失率，直接影响跳远成绩，也是评价跳远起跳技术质量的重要指标。
In the broad jump takeoff stage, the expenditure rate of level speed is important index on assessing takeoff skill quality, and influenced broad jump achievement.
水平速度总损失率偏大，运动员在第二跳、第三跳起跳时没有获得较大的垂直速度，这直接影响了二、三跳的远度和比例。
The total loss ratio of horizontal speed was rather great. The jumpers could not get great vertical speed during the second and the third jump.
