Abstract
This paper studies on running movement. In order to prevent injuries during running, we focused on the initial peak of the ground reaction force as well as the leg stiffness, and experimentally studied if visual feedback can be used to adjust these values. In detail, the ground reaction force was measured from the subject while running on an instrumented treadmill with force sensors. The initial peak of the ground reaction force was calculated from the measured data, and the leg stiffness was estimated with a spring-mass model. Then the information was visually fed back to the subject in real time. As the result, it was clarifi ed that both the absolute value and the standard deviation of the initial peak of the ground reaction force and leg stiffness were reduced with visual feedback. These results suggest that visual feedback affect running movement, and we expect visual feedback to prevent running injuries in the future.
