Abstract
A gymnastics balance beam includes a rigid elongate member of specific cross-section covered with a covering, the elongate member of specific cross-section including a planar upper surface on which is provided an elastic multilayer composite including at least two layers, namely an upper layer, and a lower layer in contact with the planar surface of the elongate member of specific cross-section. The upper layer is a layer of rubbery material and the lower layer is a layer of an elastic material of stiffness less than the stiffness of the rubbery material of the upper layer. Such a balance beam limits the risks of injury by reducing impact forces, while maintaining bearing security for gymnasts.
