Abstract
A damping mechanism for implements such as tennis rackets, baseball bats and the like, comprising an elongated vibratable member formed of an elastomeric, energy-absorbing material. One of the ends of the vibratable member is attached rigidly to the implement at a point near an anti-node, with the longitudinal axis of the member concentric with or generally parallel to the longitudinal axis of the implement. The dimensions of the member are adjusted such that the natural frequency of vibration of the member corresponds generally to the vibration induced in the implement in use as a result of striking a game ball or the like.
