Abstract
There is disclosed a shock absorber for reducing the physiological effects on the arm and shoulder as normally experienced in tennis, racquetball or the like. The absorber includes a hollow housing in which is disposed a predetermined amount of liquid of predetermined density and means for securing the liquid filled housing to the player's arm. The preferred embodiment calls for liquid mercury disposed in the hollow portion of the housing, the mercury absorbing the vibrational effects resulting from the contacting of the ball with the racquet to thus reduce or eliminate the possible adverse effects on portions of the arm, such as the elbow or the shoulder.
