Abstract

The tennis racket (30) has strings in a frame (32) of profiled rod (33), a heart zone adjacent to the frame and flanked by rod sections, a frame member (34) joining its sections, and a handle (16) on the longitudinal axis (M). The maximum height (n1) of the profiled rod at right angles to the string plane (Q) is greater than the thickness of the handle in the same direction. The profile height (h) of the frame member can be less than this max. height.
