Rate of deceleration is an important factor in determining the severity of injuries possibly sustained when participants collide with a wall assembly while playing, for example, ice hockey. Decreasing the rate of deceleration of the participant during such a collision with a wall assembly, by extending the distance over which a participant decelerates, is a key factor in reducing head and spinal injuries. The present disclosure provides apparatuses for decreasing the rate of deceleration by providing a wall assembly having a moveable piece that includes a first position and a plurality of second positions with a bias of the moveable piece to the first position. The movable wall assembly can move independently of a support frame, thereby further decreasing the rate of deceleration of a participant in a collision. The movable wall assembly can be supported on a base and slidable with respect to the base.
