摘要
从运动学、动力学的角度对跳远起跳的生物力学研究加以归纳、总结。运动学指标包括着板角、着板前三四步的步长、起跳时间等；动力学指标以测力台获得的垂直方向的力为主，较详细地总结了踏跳过程的缓冲阶段、蹬伸阶段等不同阶段的力学特征。并用压力中心这个指标分析了不同的起跳技术的特点。
Biomechanical researches on take off of long jump were classified and summarized in the light of kinematics and dynamics. The indexes of kinematics included angle stamping the board, stride length of the three or four steps before stamping the board, time of take-off; the indexes of dynamics mainly included the vertical force obtained on platform dynamometer. The kinetical characteristics in buffering, driving and other phases in the process of take-off were summed up in detail. The indicator of the center of pressure was used in examining different take-off skills.
