摘要

Sports equipment for ball games comprising a stroke portion and a shaft portion including a grip, in particular a tennis racket or a golf club, wherein mass particles (3), in particular lead shot or a liquid, are integrated into the equipment structure which are freely displaceable or freely movable thereto and which are provided in one or a plurality of chamber(s) (2) the volume of each of said chambers being small relative to the interior volume of the stroke and/or the shaft portion. The stroke characteristics of the sports equipment can be varied depending from the distribution of the chambers within the structure and/or from the amount of the mass particles (3) used. Stroke shocks are attenuated with the result that occurence of "tennis elbow" is diminished. Indicated is also a method for the manufacture of a tennis racket having high shock absorption and good oscillation attenuation properties and being manufactured in fiber-plastics-structure techniques.
