A golf Swing training device comprises a club member and at least one weight member. The weight member includes a mating Structure for Securing the weight member to a complementary mating Structure in the Shaft portion of the club member. The weight member can be secured to the shaft in at least three positions including a first position at the top of the Shaft adjacent the handle, a Second position at or near the midpoint of the Shaft and a third position at or near the distal end of the shaft.

An apparatus for racket sports practice (such as tennis, pickle ball, padel, squash, racquet ball, table tennis and the like) is disclosed. The apparatus being comprised of a tubular frame, lightweight cloth, a swivel bounce board and unique side shields that prevent balls from straying. The curved area of the rebound sheet allows users to hit balls into the apparatus and have them returned at various speeds and angles. The apparatus being of such a size that, when broken down after practice, can be easily transported by a single person. An object of the invention is to provide an affordable means for racket sports enthusiasts to practice independently.

A system is disclosed that includes a ball-throwing machine included within a first housing, a controller communicatively coupled to the ball-throwing machine and included within a second housing different than the first housing, a camera, and a non-transitory storage medium having stored thereon logic, the logic being executable by one or more processors to perform operations including: receiving information associated with a selection of a first training drill from the controller, responsive to receiving the information associated with the selection of the first training drill, causing the ball-throwing machine to impart motion to one or more balls in accordance with the first training drill, receiving multimedia data of a player captured by the camera, and performing a player recognition procedure to locate the player within the multimedia data.

A bag includes a main compartment configured to accommodate equipment, and a foldable chair compartment disposed adjacent to the main compartment. The foldable chair compartment is configured to accommodate a foldable chair in a folded configuration.

The present invention relates to a ball game racket frame with a head portion and a handle portion, wherein the ball game racket frame comprises a fiber composite with at least one multi-fiber roving that is at least partially twisted.

Described herein are devices and systems relating to sports training equipment, for example, for baseball. These devices and systems can comprise a mat with markers identifying a plurality of positions on the mat. In some embodiments, the system can comprise removably attachable footpads to identify ideal foot positions for an athletic performance. In some embodiments, the footpads comprise one or more pressure sensors. The system can comprise one or more position sensors on a ball, and one or more position sensors removably attachable to a hand-held sports instrument. In some embodiments, the system can comprise a memory, communicatively coupled to a processor and a camera, with executable instructions to implement a set-up component, a user recognition component, a practice component, and instructional component, and a play component.

An endcap system for a sporting implement includes a base portion and a transverse extension projecting from the base portion. The base portion has a bottom surface with a central axis normal thereto. A receptacle opposite the bottom surface is configured to receive a portion of the sporting implement. The extension is configured such that, during swinging of the sporting implement with a hand of a user gripping around the sporting implement portion, the extension contacts an exterior lateral portion and upper portion of a fifth metacarpal of the hand and the hand is constrained in both the transverse and longitudinal aspects while being allowed rotation of a first metacarpal of the hand away from the central axis.

The present invention relates to a ball game racket with strings that comprise at least one string comprising a superelastic material.

Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.
