摘要

According to the papers, humans do adjust their leg stiffness to accommodate changes in stride frequency or surface stiffness, while hopping in places or running forward. The purpose of this study was to determine the mechanism by which humans adjust leg stiffness during drop landing on surfaces of different stiffness. Kinematic and kinetic data were acquired simultaneously, and then the Inverse Dynamics method was used to acquire the horizontal forces, vertical forces, and the net muscle joint moments in the three lower extremity joints. The quantitative results of the present study might generate more knowledge about the motor performance and the importance of landing to be considered while teaching, coaching and training children.
