摘要：
之前剖析短跑测试图线发现增力现象，只给出平均增力系数。该文通过类机械能守恒的情景，导出竖直方向理论冲量更合理地解析式，为构建轻弹簧模型给出理论依据，为竖直方向增力现象给出二维度关系式。仔细分析竖直位移图线，明确式中各量的关系。最后构建增力现象的力学模型--缓冲垫，从逻辑上将理论冲量与实测冲量联系起来。使人地相互作用有腾空时，人体质心竖直方向运动的力学解析成为可能。

Abstract：
The energizing phenomenon is discovered from previous analysis of figure line of sprint testing, which is only to provide average energizing efficiency. This text pushes out more reasonable analysis formula of theoretical impulse of vertical direction, and provides theoretical foundation for the establishment of light spring model and two-dimension relational expression for energizing phenomenon of vertical direction through the circumstances of conservation of similar mechanical energy. The figure lime of vertical displacement is carefully analyzed and the relationship between quantities is definite. Finally, mechanical model of energizing phenomenon is established-crash pad. The theoretical impulse is logically combined with measured impulse, which is to make mechanical analysis of vertical direction of center of mass of human body become possible when the human-earth interaction is vacant.
