A multilayer anti-slip compact structure for individual/joint application on a forehand and/or a backhand side of a hockey stick blade, which contains a backing carrier (A) and an anti-slip layer (B) applied on said backing carrier (A), wherein the backing carrier (A) contains a first layer with thickness max. 0.3 mm and tensile strength min. 400 N and weight max. 130 g/m.sup.2; on the first layer, a second resin or glue layer (3) with thickness max. 0.1 mm containing polyurethane, polyacrylate, organic resin or suitable polymer, or their combination; and the anti-slip layer (B) is formed by a third resin layer (5) with content of epoxide and/or phenol or polymer with thickness max. 0.1 mm and weight max. 250 g/m.sup.2. The first layer of the backing carrier (A) is formed by a plastic film (1) from a polymer or a fibre/net structure (2) from fibres containing cotton, viscose, glass fibres, plastic fibres, polyester fibres, or their combination.

A sporting good implement, such as a hockey stick or ball bat, includes a main body. The main body may be formed from multiple layers of a structural material, such as a fiber-reinforced composite material. One or more microlattice structures may be positioned between layers of the structural material. One or more microlattice structures may additionally or alternatively be used to form the core of a sporting good implement, such as a hockey-stick blade. The microlattice structures improve the performance, strength, or feel of the sporting good implement.

An apparatus and a method that provides a helmet cap with an embedded visor on the inside of said helmet cap to train a wearer of a football helmet to correctly position the head in an up position when tacking and blocking during sports play. The cap can be detachably but securely attached to a football helmet and upper facemask in a position where it does not obstruct the view of the helmet wearer to a position where it does obstruct the helmet wearer's view and thus forces the helmet wearer to look up.

A method of assembling a portable fenced-in ball playing area that includes a plurality of panels that have an upward slot on one end of the panel and a downward slot at the other end of the panel. The panels are assembled into a polygon shaped pit, such as for a Ga-ga pit, by fitment of upward and downward slots on adjacent panels. No tools are necessary for assembly. The panels can include hand holes for easy carrying. Some panels may have a top indentation or recess to assist children in entering or leaving the fenced-in ball playing area, such as a Ga-ga pit. These panels can be reversed so that the recess is facing downward to form a goal opening for a game using a ball, puck or the like.

A wrist strengthening device includes a first handle, a second handle coupled to the first handle, and a tightening component coupled to the first handle and the second handle. The tightening component is configured to provide resistance to movement of the first handle and the second handle as the first handle is moved in a first direction and the second handle is moved in a second direction, opposite the first direction. The tightening component includes an outer piece, an inner piece, and a male and a female portion. Movement of the male portion toward the female portion causes space between the inner piece and the outer piece to decrease and friction therebetween to concurrently increase.

Systems and methods for selectively enhancing the weight and aerodynamics of sporting equipment are provided. A system may include a piece of sporting equipment having openings extending through the sporting equipment. The system may include a plug operable to be secured within one of the openings extending through the sporting equipment. The plug may include a first end portion, a second end portion, and an attachment mechanism. The first end portion may include a first outer flange and a first body. The first outer flange may have a larger diameter than the first body. The second end portion may include a second outer flange and a second body. The second outer flange may have a larger diameter than the second body. The attachment mechanism may be configured to connect the first end portion to the second end portion to secure the plug within the one of the openings.

Hockey goalkeeper leg pads wearable on legs of a hockey goalkeeper to protect the legs, in which the hockey goalkeeper leg pads may be configured to enhance performance, comfort and/or other aspects of goalkeeping of the hockey goalkeeper, including when the hockey goalkeeper leg pads drop onto a playing surface (e.g., ice) to lie substantially horizontally on the playing surface with their front facing play (e.g., as in a butterfly position or otherwise).

A hockey stick apparatus may include a molded blade structure coupled to the proximal end of a hollow shaft structure. The molded blade structure can include: a top edge spaced apart from a bottom edge by a blade height, a heel spaced apart from a toe by a blade length, a front face spaced apart from a back face, and an optional slot defining an aperture extending through front face and the back face. A stiffness of the blade may vary along the blade height by changing the shape of the blade and changing a quadratic momentum of the cross-section along the blade height.
