An exercise mat includes a fabric layer defining opposing first surface and second surface, an anti-slip strip of a predetermined width and in a predetermined pattern covered over a part of the first surface of the fabric layer so that the first surface of the fabric layer defines one or multiple exposed portions beyond the anti-slip strip, and an elastic cushion layer covered over the second surface of the fabric layer. The anti-slip strip is a continuous one-piece member defining two opposite lateral portions and a middle portion at different elevations. The fabric layer defines a plurality of local areas in the first surface. At least one exposed portion and a part of the anti-slip strip exist in each local area within a surface area approximately equal to the surface area of the palm of an adult.

A variable-color region (106) of an information-presentation structure extends to an exposed surface (102) at a surface zone (112), normally appears along it as a principal color, and includes pressure-sensitive color-change structure (132) and pressure-spreading structure (242) having an internal pressure-spreading surface (244). An object (104) impacts the zone at an object-contact area (116). The pressure-spreading structure spreads pressure of the impact along a distributed-pressure area (256) of the pressure-spreading surface. A segment (142) of the pressure-sensitive color-change structure responds to the excess internal pressure along the distributed-pressure area by causing an impact-dependent portion (138) of the variable-color region to temporarily appear along a print area (118) of the zone as changed color materially different from the principal color if the excess internal pressure meets excess internal pressure criteria. The print area thereby closely matches the object-contact area in size, shape, and location.

An adjustable club for exercise and art that has an elongate handle, at least one weight and a stud. The elongate handle acts as a counterweight to the removable weights. The elements of the adjustable club may be held together by two different types of frictional fits. The adjustable club may include only the elongate handle and the stud.

A fitness structure includes a bar having a first end portion and a second end portion, a pair of bar support portions provided at each side of the bar and having a plurality of bar support members to place the bar at a plurality of heights, a first load portion and a second load portion spaced apart from the bar to a certain degree and facing each other, a first cable coupled between the first end portion of the bar and the first load portion, a second cable coupled between the second end portion of the bar and the second load portion. Heights of the first load portion and the second load portion vary depending on a height of one of the plurality of bar support members at which the bar is detachably placed.

A head guard is provided. The head guard includes one or more sensors as part of an sensory input and communications system. The head guard wirelessly communicates data to remote computing devices for intelligent data collection.

An apparatus for testing and exercising pelvic floor musculature, the apparatus comprising an elongate housing adapted for a pelvic floor aperture. The housing accommodates an oscillator and an accelerometer connected to a signal processor configured for communicating signals representative of values read from the accelerometer. A result is calculated from an applied oscillation and a response measured, and used for characterizing the musculature. In one embodiment the frequency resulting in the greatest response from the musculature is measured, and this frequency is applied during exercise.

A system has footwear and a striking device. The striking device has a shaft connected to a striking surface for contacting an object. A sensor affixed to the shaft changes electrical resistance when the striking surface is swung to contact the object to in turn generate a signal reflective of the deflection of the shaft. The footwear is configured with an array of sensors that change at least one electrical characteristic upon deflection when the player is operating the striking device. The footwear is to send signals reflective of the deflection of the feet as the shaft is swung. The signals reflective of the deflection of the shaft and the footwear are sent to a cell phone, notebook, PC or the like suitably programmed to present audio and visual images of the feet positions and movement and movement of the striking device (e.g., golf club, racket).

Principal and secondary regions (106 and 108) of an information-presentation structure extend to an exposed surface (102) respectively at principal and secondary surface zones (112 and 114) variously impacted by a spherical object (104) that rebounds from the surface. The principal region normally appears along the principal zone as a principal color. An impact-dependent portion (138) of the principal region responds to the object impacting the principal zone at an object-contact area (116) by temporarily appearing along a print area (118) of the principal zone as changed color materially different from the principal color. The print area closely matches the object-contact area in size, shape, and location. The secondary region fixedly appears along the secondary zone as a secondary color. Restitution matching is provided across the two zones so that the rebound characteristics of the object are largely independent of whether it contacts the principal or secondary zone.

A sport combat training machine including a base assembly; a post; a shaft assembly having a spring adaptor; a mounting frame that mounts onto the post; a lower striking assembly having a first motor with a respective first adaptor having a first spring attached to a respective first lower striking arm; an intermediate striking assembly; an upper striking assembly including a second motor, with a second adaptor having a second spring attached to a respective first upper striking arm; and an electrical system having at least one computer configured with software to operate the first and second motors and a pedal for controlling the at least one computer. The intermediate striking assembly includes a body having a target area and at least one sensor. The sport combat training machine further includes a top plate assembly having at least one sensor.

A sporting device designed to help improve and teach a person as well as a trainer the correct wrist snap motion for playing many sports. This device is comprised of an adjustable wrist band that will adjust to the person's lower ulna and radius bones. with a resistance, adjustable strap around the finger/knuckle that connects from the finger/knuckle to the wrist strap. This device has an audible unit and can also have a vibration attachment as well as a counting attachment added to the wrist strap for different uses in sports or physical therapy. When the trainee is training they will make the same motion they would when they are playing said sport. This device can be set at a desired level of resistance and distance for desired wrist snapping motion. The trainee or trainer can set the desired wrist snapping motion for the device objective. When the objective is achieved the unit will respond with either a sound and or a vibration to indelicate that the desired motion was reached.
