A sports paddle including a head portion coupled to a handle portion. The head portion includes at least one core layer positioned between first and second face plates. The first and second face plates have first and second outer surfaces, respectively. The head portion defines a plurality of through-head portion holes extending from the first outer surface to the second outer surface and a plurality of grooves extending into the first and second face plates. The head portion can include first and second face plates having first and second outer surfaces, respectively, and the handle portion can include a grip. Each of the first and second outer surfaces can include a roughened region and a generally smooth region. The smooth region of the first outer surface can space apart the grip from the roughened region of the first outer surface.

A hitting extension for a body-positioning trainer is disclosed. The hitting extension has an elongate, generally flat body with first and second ends spaced from one another. The second end terminates in a rounded distal edge. A first opening formed in the body proximate to the first end allows the hitting extension to be connected to the body-positioning trainer. The body-positioning trainer restricts the movement of the arms in order to allow the user to focus on torso movement, and the hitting extension allows the user to hit a ball, or another such projectile, using the trainer. Methods for training a user in torso movement using the hitting extension are also disclosed.

A ball game racket frame includes a head portion, a grip portion and a shaft portion which connects the grip portion and the head portion. The ball game racket frame is at least partially made of at least one layer of a plurality of fibers which are randomly orientated and intertwined within the layer. According to further aspects, a ball game racket includes the ball game racket frame according to any of the embodiments described herein and a string bed plane comprising a plurality of strings which are attached to at least a portion of the head portion of the ball game racket frame. The string bed plane provides at least one striking surface for striking a game ball. According to yet further aspects, a method for manufacturing a ball game racket frame is disclosed.

Systems and methods for selectively enhancing the weight and aerodynamics of sporting equipment are provided. A system may include a piece of sporting equipment having openings extending through the sporting equipment. The system may include a plug operable to be secured within one of the openings extending through the sporting equipment. The plug may include a first end portion, a second end portion, and an attachment mechanism. The first end portion may include a first outer flange and a first body.

The plastics bat for playing ball games comprises a handle and a ball-striking head for striking resilient balls. The ball-striking head comprises a rigid outer ring frame integrally formed with the handle, a first discrete lattice structure comprising a semi-rigid single planar lattice element and an identical second discrete lattice structure comprising a semi rigid single planar lattice element. The lattice structures are securely connected to opposite sides of the frame so as to define ball-striking faces, respectively. The lattice structures define an unobstructed internal space between them. The ball-striking head has a lightweight monocoque construction wherein the lattice structures and the frame form a load-carrying outer skin surrounding the hollow internal space.
