摘要
采用文献综述法，对影响跳远起跳速度的有关因素进行分析。结果表明：提高助跑速度和助跑最后二步节奏，有利于加快起跳速度；适宜的着地角是加大上极速度、获得较大冲击力的前提；较早的蹬伸能获得较长的重心工作距离，缩短起跳时间，提高起跳效果。
By the literature summary, the paper analyzes the related factors affecting the takeoff velocity of long jump. The results show that to increase the approach speed and the rhythm of the final two steps in the approach is beneficial to the increase of takeoff velocity; the proper landing angle is the prerequisite to the increase of up - board speed and obtainment of larger impulsive force; the earlier drive - stretch can obtain longer gravity working distance,decrease the time of takeoff, and increase the effect of long jump.
