A racket 2 includes a frame 4, a grip 6, a grommet 10, and a string 12. In the racket 2, an in-plane stiffness index Gi, which is a ratio of a top pressure stiffness value Git (kgf/cm) to a side pressure stiffness value Gis (kgf/cm), is 1.40 or greater; an out-of-plane stiffness index Go, which is a product of a throat stiffness value Gos (kgf/cm) and a ball-hitting face stiffness value Goh (kgf/cm), is from 60000 to 85000; a moment of inertia Mi about an axis of the racket 2 is from 13500 g.Math.cm.sup.2 to 15000 g.Math.cm.sup.2; and an index of inertia Ii is 0.150 or greater, which is calculated by the following mathematical formula: Ii=Mi/(Wr.Math.Lc) (where Wr is a mass (g) of the racket, and Lc is a distance (mm) from a grip end to a center of gravity of the racket).

A racket includes a frame 4. The frame 4 includes a head 14. The head 14 includes a first high-elasticity layer 37a and a second high-elasticity layer 37b. Each of these high-elasticity layers 37 is positioned on an inner side in the head 14 in a thickness direction of the head 14. Each high-elasticity layer 37 includes straight-type reinforcement fibers. In the frame 4, a ratio (G2/G1) of a ball-hitting face stiffness value G2 to a side pressure stiffness value G1 is greater than or equal to 3.20. In the frame 4, a ratio (Tf/Wf) of a thickness Tf of the frame 4 to a width Wf of the frame 4 is preferably greater than or equal to 2.0.

A pickleball racket with shock-absorption rings comprises: a racket potion; and a handle portion connected with the racket portion; wherein, the racket portion comprises a facing and a main panel, the main panel comprises a main panel frame, a first shock-absorption ring, a first honeycomb panel and a second honeycomb panel, the first shock-absorption ring is arranged in an inner ring region of the main panel, the first honeycomb panel is inlaid in a region between the main panel and the first shock-absorption ring, and the second honeycomb panel is inlaid in an inner ring region of the first shock-absorption ring. The first shock-absorption ring arranged around the second honeycomb panel can effectively isolate vibrations when a hitting point is located in the region of the second honeycomb panel, to greatly reduce vibrations transmitted to the handle portion, thus guaranteeing good hitting comfort of the pickleball racket.

A racquet including a frame including a head portion, a handle portion, and a throat portion. The head portion forms a hoop that defines a string bed plane. The head portion of the racquet being formed of a fiber composite material. When the racquet is tested under the racquet lateral bending test, the racquet has a lateral deflection of at least 6.5 mm when measured in a first direction that is parallel to the string bed plane and perpendicular to the longitudinal axis. When the racquet is tested under a racquet forward/rearward bending test, the racquet has a forward/rearward deflection with respect to the longitudinal axis of less than 7.3 mm when measured in a direction that is perpendicular to the string bed plane and perpendicular to the longitudinal axis.
