A pronation supination wrist deviator exercise device includes a handle having a proximal portion and a distal portion; a shaft defining a longitudinal axis extending from a proximal end to a distal end; and a head portion having a predetermined weight. The head portion or the handle are mounted for relative movement on the shaft between a first position and a second position. The head portion and the handle define a first distance. The predetermined weight of the head portion represents a first weight. The first weight multiplied by the first distance represents a first effective torque of the device. When the distance between the head portion and the distal portion of the handle is changed to at least a second distance, the first weight multiplied by the second distance represents at least a second effective torque of the device.

A device has a lightweight inner bladder and an outer layer that covers the inner bladder. The inner bladder bunches up, crunches, becomes pleated, folded or the like against the inner surface of the outer layer. The bunched up surface of the inner bladder may be flattened and/or reconfigured upon impact, thereby absorbing energy. The bunched up inner bladder may create an uneven surface on the outer layer thereby altering the manner through which the device travels through the air. The device may be configured for any of a variety of sports or games such as, for example, a simulated soccer ball, football, rugby ball, baseball and/or softball, a tennis ball, a beachball or other oversized ball, a golf ball, a flying disc, a weighted punching bag, or any of a wide variety of devices for play and/or training.

The present invention is a glow in the dark volleyball set with two illuminated volleyball poles, and an illuminated net stretched between the two volleyball poles. The glow in the dark volleyball set where the volleyball poles may be illuminated by LED lights or reflective material. The glow in the dark volleyball set with poles that may have integrated solar panels to sustain illumination. The glow in the dark volleyball set where the net is illuminated by LED lights or by reflective material.

An impact resistant ball and process of forming an impact resistant ball are provided. The impact resistant ball has an increased resistance to damage caused to a ball by repeated impact with objects such as a game board and game pins thereby decreasing the frequency with which the ball must be replaced. The impact resistant ball also has utility to afford a larger segment of the population the ability to properly grip and throw the impact resistant ball by providing an increased length gripper able to accommodate a greater range of hand sizes. In impact resistant ball has further utility to automatically identify and transmit data including the impact of the ball with the game pins and ball metrics including speed, pressure and weight.

The invention is a portable and customizable Skelzies-like game that includes multiple customizable mats and game pieces, which are each adapted to allow the game pieces to slide upon the mats

Provided are a golf ball which has a surface that sparkles when exposed to ultraviolet rays even if a naturally derived substance is used as a fluorescent material, and it is environmentally and human friendly, and a resin composition for a cover or a topcoat therefor. A resin composition for a cover or a topcoat of a golf ball of the present invention includes: a resin for a cover or a topcoat; and a plant-derived or alga-derived extract which emits light using an absorbed light as an energy source, as a fluorescent material. In the golf ball of the present invention, the cover or the topcoat is formed by using such a resin composition.

Embodiments of the present invention provide a toy deformable to several structural configurations. The toy includes two endcaps connected by a plurality of pliable ribs. The toy may be deformed into a low-profile configuration by pressing the endcaps together, the ribs bending outward to accommodate the deformation. The toy may be deformed into a high-profile configuration by squeezing the ribs together, the endcaps being pushed apart to accommodate the deformation. While pressure is not applied to the toy, the toy may enter a non-deformed configuration wherein the ribs and the toy as a whole take on a substantially spherical form. A retention device may also be utilized to confine the toy to a specific configuration.

A kind of glow ball comprises a ball shell made of flexible and transparent material, and an empty cavity is formed in the said ball shell. The said empty cavity contains chemiluminescent reagents (2-A, 2-B), and the said chemiluminescent reagents solid or liquid or solid-liquid mixture, and the said chemiluminescent reagents are two kinds of reagent sealed separately and can generate chemiluminescent reaction when they are combined. At least one kind chemiluminescent reagent is contained in one or more breakable containers. The application adopts that the inner wall of the ball shell is with protrusions or polyhedral or many pits or grooves and/or protrusive ribs and is placed with dispersed particles, such as scraps of paper, plastic film, or small plastic particles, etc.

A pronation supination wrist deviator exercise device includes a handle having a proximal portion and a distal portion; a shaft defining a longitudinal axis extending from a proximal end to a distal end; and a head portion having a predetermined weight. The head portion or the handle are mounted for relative movement on the shaft between a first position and a second position. The head portion and the handle define a first distance. The predetermined weight of the head portion represents a first weight. The first weight multiplied by the first distance represents a first effective torque of the device. When the distance between the head portion and the distal portion of the handle is changed to at least a second distance, the first weight multiplied by the second distance represents at least a second effective torque of the device.

A height adjustable combat training assembly and method of operation enables a practitioner to strike with a fist, kick, hurtle over, and reenact combat with a real person through use of a height adjustable series of shafts, target accessories, and elongated barriers that are manipulated into myriad configurations. A base portion is filled with a weighted substance to stabilize the assembly. A base shaft attached perpendicularly into the base portion. A height adjustable shaft extends from the base shaft in a sliding relationship that is measured with a height gauging instrument. Padded sleeves encapsulate both shafts for cushioning. A flexible member extends form the terminus of the height adjustable shaft. A terminal target rests on the terminus of the second sleeve. A label attaches to the sleeves. At least one target accessory detachably attaches to the shafts or sleeves, and includes linear arm, blocking arm, laser device, and fist.
