ABSTRACT:
A ball game racket, especially a tennis racket, has a racket head formed by a tension frame with stringing, and a handle unit formed by a handle shaft or a racket neck joining the tension frame for example via a heart piece. Between a frame profile and the support profile a hose or cushion-type element is filled with an attenuating or damping liquid.
