A shock-absorbing handle structure for a sports racquet includes a main core body. An outer surface of the main core body is partially or completely covered with a shock absorbing structure. The shock absorbing structure is made of an ETPU (expanded thermoplastic polyurethane) material. The ETPU material is used as the shock absorbing structure. The shock absorbing structure is attached to the outer surface of the main core body, which has a simple structure. The ETPU material has a better elastic and rebound effect and improves the shock absorbing effect of the whole handle effectively. It is light in weight, and can improve the hand feeling and enhance the anti-slip effect and prevent sports injuries.

Various embodiments for a swing mechanics shoulder harness and barrel ax are described. The swing mechanics shoulder harness and barrel ax may be used to train an operator the proper biomechanical sequence of a swing. The swing mechanics shoulder harness and barrel ax includes a shoulder harness, a shoulder portion, a chest portion, a first coupling section, a second coupling section, and at least one wrist attachment.

A ball bat includes a barrel wall with perforations positioned within a ball striking area of the bat. Perforations may extend through all or part of the barrel wall. In some embodiments, a filler material may be positioned in the perforations, or a cover element may be positioned over the perforations, to form a generally flush surface between the filler material and a surface of the barrel wall. Filler material may be less dense than material forming the remainder of the barrel wall. In some embodiments, a barrel wall may include a plurality of layers of composite laminate material. One or more of the layers may have perforations positioned radially between the other layers. In some embodiments, the perforations in the composite laminate material may be generally aligned to form a larger perforation extending through all or part of the barrel wall.

The present disclosure generally relates to virtual reality simulation, and more specifically, in some implementations, to devices, systems, and methods for use in a virtual reality sports simulation. A system for virtual reality simulation may include an accessory (e.g., one or more of a bat, a glove, or a helmet) for interacting with a virtual reality environment. The accessory may provide the user with haptic feedback that emulates sensations that the user would experience when playing a live-action sport to provide the user with a more meaningful and realistic experience when playing a virtual reality game. Further, virtual reality simulations disclosed herein may include incorporating data from a live-action event (e.g., a live-action sporting event) into a virtual reality environment to provide a user with a realistic experience.

Described is a sports training system that can be used to assist pitchers in identifying foot placement and mechanics during a pitching motion. The sports training system includes a mat and plurality of foot pads. The mat is designed to have at least a pitching plate and a plurality of grid zones, while the foot pads are used for placement in one or more of the plurality of grid zones to assist the pitcher with foot placement.

A handle for sport equipment comprises a tubular body (7) which extends along a longitudinal axis (L) and has an outer peripheral surface (8) adapted to be grasped by a user and shaped with a plurality of longitudinal faces (9) placed side by side in correspondence of edges (10) adapted to facilitate the positioning of the finger joints of the gripping hand by the user. The edges (10) are arranged along at least one pair of helical or spiral paths that develop around said longitudinal axis (L) with mutually opposite sign to subdivide each of said longitudinal faces (9) into a plurality of areas or flat surfaces (11) sized to accommodate a corresponding phalanx of the gripping hand of the user, each of said areas or flat surfaces (11) being perimetrically delimited by at least one pair of edges (10, 10) of each of the helical or spiral paths.

A ball bat extending about a longitudinal axis and configured for testing under an accelerated break-in test. The bat includes a barrel portion that includes an inner surface and is formed of a fiber composite material having wall thickness of at least 0.100 inch. The fiber composite material includes at least first and second plies. The first ply includes a first plurality of fibers aligned adjacent to one another and a first resin, and the second ply includes a second plurality of fibers aligned adjacent to one another and a second resin. The inner surface of the barrel portion defines at least one annular groove. The at least one annular groove creates an ABI fuse region of the barrel portion. The ABI fuse region forms a crack initiation location when the bat is subjected to the accelerated break-in test.
