A tennis racket comprising a frame having two spaced apart peripheral rows of threading openings for two spaced apart string cord layers, and an intermediate flexible layer in at least the central interspace area between said two string cord layers to interconnect said two string cord layers.

An energy-absorbing game racket designed as a pair of planar surfaces extending from a handle constructed as a sandwich design within a frame, with a set of coil springs compressed within the space defined between opposing surfaces. One of the surfaces is mounted to move within the frame against the springs such that it has a springy characteristic, while the other surface is stiff. In a racket ball game volley, either surface may be directed so that the ball impacts it. When the springy surface is directed toward the ball, it partially absorbs the impact force thereof, while the stiff surface does not. This design enhances the player's ball control options in delivering the return volley. An additional feature of the inventive game racket is the provision of an audio indication associated with impact of the ball on a particular area of the racket surface. A lamp and counter may also be provided for this purpose. By designating a particular area of the racket surface as the target, a player's expertise in achieving ball control accuracy can be measured. The inventive racket affords an additional level of competitiveness to the existing racket ball sport, enabling development of new games with new play strategies and point scoring schemes. For example, if a targeted area of the racket has been designated, this may be used to provide a ball control accuracy measurement, with a player scoring extra points for each target hit recorded by the counter and/or the audio-visual signal.

A perforated bat for playing games such as paddle tennis, tether ball and others, has a monolithic unstressed striking head which comprises a pair of outer lattices which form the striking surfaces; and these lattices are joined by a third internal core lattice which has at least one longitudinal and one lateral web spanning the two outer lattices.

A disk is provided with two diametrically opposed handles. A resilient ball is tethered to the center of the disk by a flexible, but substantially inelastic line, said line being slightly shorter than the radius of the disk. Weights may be attached to the device. Proper flexions and extensions of the arms or of other parts of the user's body set the ball in a periodic bouncing motion. The rhythm thus established regulates the various exercises of the user.

A game racket having an elastic net and a frame molded in unison, the net comprising non-linear elements which work primarily in bending and whose cross sectional area increases toward the center of the net.
