A twist-inhibiting collar for sports is disclosed. The twist-inhibiting collar includes a first surface configured to engage with an ulnar edge of a first hand of a player, and a second surface configured to engage with a radial edge of a second hand of the player, the second surface opposite the first surface. The collar also includes an aperture passing through the first surface and the second surface and defined by an interface surface that is coupled to a sport implement held by the player. The twist-inhibiting collar includes an elastomeric material. The sport implement may be a bat having a handle, and the aperture may be sized to fit the handle. The sport implement may be a golf club having a grip, and the aperture may be sized to fit the grip.

The present disclosure provides for various objects (weights, playing apparatuses, balls, clothing, etc.) that have liquid disposed in them to assist in building and strengthening small muscle fibers and/or nerves. The various objects can include weights, playing apparatuses such as objects that can be swung in sports, balls, and clothing or other objects that can be worn by humans or other animals. The objects include fluid paths and re-directions walls disposed within the fluid paths to direct fluid flow to particular areas within the objects. The designated areas to where fluid flow is directed aid in development of small muscle fibers and/or nerves due to the fluid sloshing around at those particular locations. Methods of making and using the various objects disclosed are also provided.

A piece of tubular sports equipment includes: a first layer of composite material including fibers oriented in a first direction; a second layer of composite material that directly contacts the first layer of composite material, that is arranged radially outwardly of the first layer of composite material, and that includes fibers oriented in a second direction that is different than the first direction; and a third layer of composite material that directly contacts the second layer of composite material, that is arranged radially outwardly of the second layer of composite material, that includes fibers oriented in a third direction that is different than the second direction, and that includes an aperture formed through the third layer such that a portion of the second layer is visible through the aperture.

A ball bat includes at least one disc member in the bat barrel. The at least one disc member may include at least one solid disc member or at least one non-solid disc member with an opening, or both. The outer perimeters of the disc members may optionally be separated from the inner wall of the ball bat by a buffer layer, such as a layer of open-cell foam or adhesive. In some embodiments, the ball bat may further include at least one positioning member, such as an insulation foam member. The at least one positioning member may be located between two disc members, and multiple positioning members may optionally be arranged in alternating fashion with disc members within the bat. The at least one positioning member may be an insulation foam member having a hollow center portion.

Hand positioning accessories for bats and other sporting goods are described. The hand positioning accessory may include an exterior surface that is at least partially concave in shape and comprises a base comprising an apex and an interior surface that is at least partially convex in shape and faces the handle of the sporting good. The exterior surface may also include a plurality of longitudinal ribs/protrusions. The hand positioning accessory may create an ovular-shaped handle region for better performance.

A sports ball for use in baseball-type games includes a hollow, substantially spherical plastic ball that has a plurality of substantially planar, intersecting regions covering an outer surface thereof. Preferably the ball also has a weight that is substantially less than a weight of a regulation baseball, for enhancing safety in use. The sports system further includes a bat for use with the ball, or with any similar ball, preferably a plastic ball. The bat is a hollow, elongated member that has a handle portion adjacent a bottom end and a barrel portion between the handle portion and a top end. The bat further has a sheath surrounding at least a portion of the barrel portion. The sheath has a coefficient of friction higher than a coefficient of friction of a surface of the barrel portion, for imparting “traction” to a struck ball.
