Braggemann and his co workers, Germany has presented papers on “Decoupling of the tennis racket frame decreases grip vibrations”. They discussed that tennis elbow problem is often associated with vibrations initiated by the racket. To decrease the risk of this, racket design is focused on damping the vibration of the grip. They made design which will transmit vibration to the player's arm rather than restricting to the grip only. The purpose of their study was to investigate the effect of a damping element in a racket on the transition of vibrations from the frame to the grip.
