The purpose of this study is to investigate the relationship between the parameters of human running model and a cushioning efficiency in a vertical ground reaction force in human running with three different sports surfaces. Seven experimental running data were used for searching an each set of parameters for mathematical model of human running without sports surface. The mathematical running model with each parameter set was dropped on the mathematical sports surface model proposed by Kobayashi and Yukawa. In order to investigate the influence of parameters to the ground reaction force absorption, a sensitive test was adopted with ±3% range of parameter value with an analysis of runner-sports surface coupled system. In this paper, the relationship and the sensitiveness of each parameter and the cushioning characteristics in vertical ground reaction force was discussed.
