<p>A tennis racquet 1 having advantageous shock absorbency characteristics consists of a frame 2 which supports an open network of strings 3, the frame 2 comprising a substantially stiff support member 11 and an inflatable member 12 which is variably inflatable by means of a valve 18. The network of strings 3 is supported from the frame so as to define two outwardly-facing playing surfaces which are each generally concave, the network 3 comprising a substantially planar central portion 13 and surrounding peripheral portions 14 inclined thereto. The string elements 4 of the network have nodular portions 15 and are preferably multifilamentary. <IMAGE></p> |
