A tennis racquet extending along a longitudinal axis and capable of being tested under a lateral bending test and a forward/rearward bending test, includes a frame having a head portion, a handle portion, and a throat portion positioned between the head and handle portions. The head portion forms a hoop that defines a string bed plane. At least the head portion and the throat portion of the racquet are formed at least in part of a fiber composite material. The throat portion includes a pair of throat elements. When the racquet is tested under the lateral bending test, the racquet has a lateral deflection of at least 6.0 mm when measured in a direction parallel to the string bed plane and perpendicular to the longitudinal axis.
A tennis racquet extending along a longitudinal axis and capable of being tested under a racquet lateral bending test and a racquet forward/rearward bending test, wherein the racquet lateral bending test includes mounting the racquet in a first orientation to a first test fixture at a first longitudinal location, attaching a clamp to the racquet at a second location, operably engaging a deflection indicator to the clamp, applying a first predetermined weight to the racquet at a third location, and removing the first weight to obtain a lateral deflection measurement of the racquet with respect to the longitudinal axis, and wherein the racquet forward/rearward bending test includes mounting the racquet in a second orientation to the first test fixture at the first longitudinal location, applying a second predetermined weight to the racquet at a fourth location, operably engaging the deflection indicator to the racquet at a fifth location, and removing the second weight to obtain a forward/rearward deflection measurement with respect to the longitudinal axis, wherein the racquet is rotated 90 degrees about the longitudinal axis from the first orientation to the second orientation, the racquet comprising:
