Training apparatuses are provided that include a substantially spherical, hollow shell formed from a pair of hemispherical portions. The hemispherical portions may each include an annular peripheral edge having a fastening mechanism, which may be adapted to provide rigidity and structure to the training apparatus. At least one hemispherical portion may further include a number of protrusions extending along an inner surface from the peripheral edge, the protrusions configured to provide structural support and durability to the training apparatus.

Golf ball comprising layer(s) consisting of a mixture consisting of: i) ethylene acid copolymer(s) and/or ionomer(s); ii) polyethylene(s); iii) polymeric epoxy crosslinker(s); and iv) compatibilizing polymer(s). The ethylene acid copolymer(s)/ionomer(s) and the polyethylene(s) may be included in a blend in a wt % ratio of from about 85:15 to 55:45; the at least one polymeric epoxy crosslinker and compatibilizing polymer may be included in amounts, based on 100 parts of the blend, of from about 2.0 to about 10.0 parts; and from about 1.0 to about 10.0 parts, respectively. The polyethylene may be polyethylene butene; polyethylene hexene; polyethylene octene; and combinations thereof. Each ethylene acid copolymer, polyethylene, polymeric epoxy crosslinker, and compatibilizing polymer has a density less than 1.0 g/cm.sup.3. The mixture is moldable and meanwhile possesses similar desirable CoR, DCM compression, Shore D hardness, and Shore C hardness as a mixture consisting of ingredients i), ii) and iv).

In an aspect, an apparatus is provided and includes an air-tight object having an outer layer, an inner layer, and a cover, and a light module. The opacity of the outer layer is greater than the opacity of the inner layer. The outer layer defines a first aperture and a second aperture. The inner layer and the cover define a first interior region. The inner layer defines a second interior region. The light module is encapsulated within the first interior region and is configured to send light through the inner layer, through the second interior region of the air-tight object, and through the second aperture of the outer layer, wherein the cover is disposed between the light module and the outer layer.

A luminous ball with remote activation capability includes a sphere, a cover and a light-emitting device. The cover wraps an external circumferential surface of the sphere and is made of a light-transmissive material. At least one seam is formed on the cover, and a plurality of seam apertures are disposed in pairs along two sides of the at least one seam. The light-emitting device is disposed in the sphere and includes a light-emitting unit, a power unit, a wireless transmitter-receiver unit and a main control unit. The main control unit is operably configured to provide an electrical connection between the light-emitting unit and the power unit after obtaining an activation signal received by the wireless transmitter-receiver unit such that light emitted by the light-emitting unit penetrates the sphere and the cover and is visible through the at least one seam and the plurality of seam apertures.

Disclosed herein is a sporting ball with a specific image printed on the sporting ball. The image is generated, selected, or captured by a user, which triggers a process for printing the image onto the ball. Further disclosed are systems and methods for printing and delivering the sporting ball with the image. The image may be an image of the user, a favorite sports athlete, or a celebrity. Certain preferred embodiments utilize a basketball, a soccer ball, or a football. However, alternative embodiments may include any type of sporting ball. The image may be captured by numerous means recognizable by those skilled in the art, including but not limited to a computing device, a cellular phone, a tablet, a web cam, a digital cam, and other traditional non-digital cameras.

A sports ball, such as a lacrosse ball, comprising, an outer shell layer defining an enclosure having an interior volume for housing a filler material, the outer shell layer comprising a plurality of sections (pads or panels) connected along a plurality of seams, the sections having an outer surface comprising one or more layers of a substantially smooth non-woven synthetic leather, such as a synthetic suede, microfiber, or micro-velour, with an optional surface coating, which produce a frictional resistance (coefficient of friction) which decreases ball slippage against a surface or when released from the strings of a lacrosse stick.
