Abstract: An apparatus for the balance training of athletes, such as downhill skiers, is disclosed, and which comprises a base adapted to rest upon the floor, and a foot plate mounted in spaced relation above the base. The foot plate and base are interconnected by a plurality of springs disposed in a circular arrangement around the center of the foot plate so as to permit tilting of the foot plate relative to the base in all directions. Drive means is also provided for imparting a continuous irregular tilting movement to the foot plate, and which includes an electric motor, a vertical centerpost connected to the output of the motor, an undulating cam plate fixed to the underside of the foot plate, and a follower fixed to the centerpost. Thus upon operation of the motor, the centerpost is rotated and a continuous irregular tilting movement is imparted to the foot plate.

Abstract: Apparatus for simulated skiing having a pair of assemblies each comprising a frame, at least two rollers rotatably mounted in parallel for rotation in said frame, an endless flexible element mounted on said rollers for movement around said rollers, a foot plate, means for transmitting a skier's leg movements to said element, an adjustable brake to provide adjustable resistance to said movement of said element and one way drive means between said brake and said element to permit movement of said element free from said adjustable resistance in one direction, said frame having stop means restricting movement of said foot plate, said one way drive means comprising complimentary teeth on said element and a said roller, the teeth being shaped and oriented so as to overide one another in said one direction and drivingly to engage one another in the opposite direction, said brake acting upon said roller having teeth; and a pair of stave assemblies each comprising a frame, at least two rollers mounted in parallel for
