摘要: A modified mass-spring-damper model was used to simulate the vertical ground reaction forces of a human runner as stride length altered. Spring stiffness values were selected by an optimizing routine that altered parameters match force curve runner’s actual curve. mass in series with spring behavior body structures produce active portion force. second spring-damper system those components cause impact The showed 51% decrease subjects increased their length. value trend opposite spring, increasing 20% strides lengthened. It appears plays role preventing support leg from collapsing response contact velocities ...
