Abstract (en)
A racket has a hand grip (13) joined to a frame having a shank region (11) and flaring outwards in a throat region (12) and extending around a generally oval ball-hitting region stand by transverse strings (17) and longitudinal strings (15). A central plurality of the strings (15) have a strung length at least 30% longer than all other strings in the network and that this central plurality includes at least one third (1/3) of all the longitudinal strings in the network. The longer longitudinal strings are strung with at least 30% more tension than all other strings in the network so that the longer strung length and the greater tension causes the longer longitudinal strings to provide a greater share in the transverse strangs of the string force that decelerates a ball penetrating the string network in the central region occupied by the longer longitudinal strings.
