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

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 solo practice sport training tool providing a true return flight trajectory of a sports ball. The tool comprises a tether anchored at a proximal end and attached to a sports ball at the distal end, wherein the tether has an clastic first length and an inelastic second length.

A goal apparatus comprising a cross bar, a first side post and a second side post is described. The first side post and the second side post are connected to the cross bar such that the first side post, the second side post and the cross bar form a plane (a goal plane). Further, one or more sensor pairs are coupled to the first side post and the second side post, wherein a first sensor pair of the one or more sensor pairs includes a first sensor and a second sensor. The first sensor is coupled to the first side post and the second sensor is coupled to the second side post and is also aligned horizontal to the first sensor. In addition, the first sensor pair is located in a first zone, wherein the first zone is a first portion of the goal plane.

The disclosure discloses a thermal expansion compound for handles, a preparation method, and applications thereof. The thermal expansion compound for handles is prepared by 20-80 wt of thermosetting resin, 5-50 wt of foaming agent, 5-50 wt of stuffing, and 0-60 wt of diluent. The thermal expansion compound for handles applies to the preparation of various sports instruments such as tennis rackets, badminton rackets, squash rackets, PK rackets, beach rackets, flexible rackets, ball bats and clubs. Handles prepared from the thermal expansion compound have an elegant appearance and a good hand feel, avoid secondary expansion during 100-160 C. post-heating treatment, and have a hardness of SHORE D 60-95.

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.

The present application is direction to a computing device having a memory and a processor. The processor is configured to receive data generated in response to a motion of a sporting apparatus, where the data includes a first data relating to a first characteristic of the motion of the sporting apparatus. The first data is based on a comparison between at least two different directional segments of a path created by a first location on the sporting apparatus during the motion of the sporting apparatus. The processor is further configured to analyze the data to determine a skill value, determine a recommended sporting apparatus from a group of at least two sporting apparatuses based on the skill value; and transmit information relating to the recommended sporting apparatus.

A play device for a rebound sport with a play area is provided, on which a ball can be played by a player to rebound from an impact position in accordance with a predetermined set of rules of the rebound sport, which includes a sensor system configured to detect two-dimensional first coordinates of the impact position and to transfer the two-dimensional first coordinates to a computing unit configured to determine two-dimensional second coordinates, a size and/or a shape of a target field depending on the first coordinates in accordance with a predetermined specification and to control a projector to project the target field to be optically perceptible by the player on a projection area, wherein the ball can be played by the player on the target field to rebound from the target field in accordance with the set of rules of the rebound sport.

A weight apparatus suitable for attaching to athletic equipment includes a flexible main body of a weight material, wherein the flexible main body is formed into a flattened strip that has a length along its y direction that is significantly greater than its width along its x direction, wherein the flexible main body is configured to be malleable to conform in a curved manner to wrap along a head of a sporting racket and around a handle of a hockey stick.

An exercise training system is provided having a system controller and a plurality of stimulant target units connected via a wireless network to the system controller. Each stimulant target unit has a light source providing light to stimulate a user, a proximity sensor providing an output of a distance between the proximity sensor and an object external to the unit, and means for providing feedback to the user to signal that the unit has been actuated by the user. The system controller includes a program for activating the stimulant target units in a sequence. The reaction by the user to the illumination is registered when the user brings a body part or other object to within a selected distance of the proximity sensor, this distance being programmable by the user.
