A ball throwing device including a lower handle portion, a middle lever portion, and a head portion. The middle lever portion may include a plurality of latitudinal bends positioned between the lower handle portion and the head portion. Additionally and/or alternatively, the head portion may include a half-spherical cup configured to releasably retain a ball, the half-spherical cup having a plurality of edge lobes configured to flex over an outside diameter of the ball.

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.

In an example embodiment, a golf club shaft is disclosed that comprises: a grip portion and a central shaft. The central shaft comprises a plurality of holes capable of being removably filled by one or more weighted plugs. In various example embodiments, the weighted plugs may be any weight desirable to the golfer, and may be positioned at any location on the shaft where there is a hole to customize the weighting of the golf club. In such embodiments, the weighted plugs may be made of a high density material and may weigh above about 14 grams.

A preferred embodiment of a novel paddle for use in racquet sports, and particularly table tennis, is disclosed. The paddle features a handle which is designed to comfortably conform to the players grip, while both enhancing total backhand play and allowing for ease of rotation to forehand play at any time on either side of the body; Thus, a paddle which eliminates ever being caught out of position. The alignment for the attachment of the handle to the blade is what is specifically unique.

An ergonomic grip for strength conditioning has a grip body composed of three adjoined, progressively larger oblate spheroids. The major and minor diameters of the spheroids and their spacings combine to form invected surfaces at the junctions of first and second and second and third spheroids. These invected surfaces admit curved fingers of a grasping hand to provide a secure grip while eliminating a common problem of the little finger (4th finger) of the hand being crushed or discomforted. A central shaft passes through the grip body and includes an attachment affordance at one protruding end, and is coupled to a washer at the other end. A central cavity in the grip body allows the spheroids to compliantly conform to the inner concavities of an individual user's palm for increased comfort and positive grip. They eyebolt may also swivel to align itself to a connected cable during use.

A hand grip support device is provided which includes a shaft having a tapered leading edge portion formed on a first side of the shaft and a curved edge portion formed on a second side of the hand aid device where the first side is opposite to the second side. A user may grasp the hand grip aid device so that the tapered leading edge portion is supported by the fingers in a closed first position while the curved edge portion is configured to receive a round or cylindrically shaped object, allowing the user to properly grasp round or cylindrical objects resulting in greater grip strength and less hand fatigue.

Devices systems and methods are disclosed. Among other things, the devices systems and methods can facilitate ergonomic gripping of a handle; conform to the shape of a wrist; enhance golf techniques or performance; enhance racket sport technique or performance; protect a head of a user engaged in contact sports or other hazardous activities; identify concussions, in some cases in substantially real time; provide sterilization of garments; control surgical robots; allow for medical treatment of multiple subjects without disrobing; provide biometric or other data; and/or be used to train muscles or body parts for, for example, performing specified tasks using a body part.
