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.

A composite material body (10) includes a first material layer (20) and a second material layer (30) overlapping the first material layer (20). The first material layer (20) and the second material layer (30) are wound to form a flexible and circular rod. Impact absorption is effectively improved and impact resisting strength is enhanced because energy-absorber or damping material or its composition is attached into the composite material body (10). Technical characteristics, effects and objects of this invention are achieved thereby.

An improved racquet handle, such as for a tennis or racquetball racquet, comprised of a flex control device that enables a user to adjust the flexibility of the racquet handle. The increased flexibility of the racquet handle enables a user to impart greater force on a ball, such as a tennis ball, and also dampens or reduces the amount of vibration and/or shock otherwise imparted to the racquet user when the racquet strikes the ball. The flex control device of the present invention is comprised of a fixed insert portion and an interchangeable, removable insert that enables a user to control the amount of the flexibility of the racquet.

Methods, apparatus and kits for modifying natural feathers that are used in sporting goods that result in long lasting feathers with increased mechanical stability, reliability and durability as well as improved flight consistency are disclosed. Some of the sporting goods that use natural feathers are badminton shuttlecocks, arrow fletchings, and darts. The disclosed methods consist of controlled treatment of feather shuttlecocks with crosslinking agents to crosslink the keratin protein present on the natural feathers of the shuttlecock.

A sports training/exercise apparatus attached to a swinging sports apparatus, typically a racquet and most specifically a tennis racquet. The apparatus includes a drag chute with a rigid member disposed therearound and a clamp secured to each side of the drag chute. A transverse support rod is positioned between the clamps and includes an aperture therein, The apparatus further includes brackets at the top and bottom of the racquet head. A longitudinal support rod is positioned between the brackets and extends through the aperture in the transverse support rod. Thus, the transverse support rod, the side clamps, and the drag chute are slidable along the longitudinal support rod to adjust resistance. A locking mechanism can be used to lock the transverse support rod in a position along the longitudinal support rod.

A special 21-point electronic score device for games like Corn Hole. It is a portable, easy-to-see electronic scoreboard designed specifically for the popular backyard game of cornhole. It is made of durable materials with a fold-in base and includes 42 LEDs (21 on each side) stacked in the traditional score tower style that allows it to be used any time of day or night. It stands approximately fifty (50) inches high when in use and then can fold down to approximately thirty-six (36) inches for easy storage and portability. It has a handle for convenient carrying, a drink holder, and a compartment on top to hold a phone in place for video recording competitive games. The scoreboard can be used for any game played to 21 points.

A sports product may include a support member and an impact region configured to impact an object. The impact region may be coupled to the support member. The sports product may also include a shear thickening material in at least one of the support member or the impact region. The shear thickening material may be configured to exhibit shear thickening behavior when an impact occurs between the impact region and the object.

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

A tactile reference attachment for releasable attachment to a sports equipment handle providing a user with tactile biofeedback. The attachment includes a tactile reference feature that extends longitudinally along an exterior body surface and is formed with dimensions specifically tailored to harness the user's natural attributes of sensibility, proprioception, and neuromuscular memory to improve a user's accuracy. The tactile reference attachment includes a flexible primary substrate having a plurality of attachment perimeter edges, an exterior surface, an interior surface having an adhesive, a thickness, and at least a first tactile reference projection having a plurality of perimeter edges, a projection width of no greater than 5.0 millimeters, a projection height of at least 0.5 millimeters, and an indentation length.

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.
