A system for changing the stiffness of a ski, said system comprising: a support member having a fixed end portion attached to an upper surface of the ski and a free end portion movable longitudinally along the upper surface of the ski as the ski bends; and impedance means operatively engageable with said free end portion as inertial forces are applied to the ski, said impedance means includes a control member mounted for pivotable movement about a fixed axis disposed transversely to said upper surface, an end portion of said control member having an inertial mass for producing lateral pivotable movement of said control member in response to inertial forces acting on said control member, said control member being biased to a longitudinally aligned position in the absence of said inertial forces, said free end portion being configured to provide free longitudinal movement of said support member relative to said control member when said control member is in said longitudinally aligned position for permitting free bending of the ski and to engage said control member when said control member is in a laterally displaced position in response to said inertial forces for limiting bending of the ski.
