A high-speed skatemill with a movable skatemill belt that includes a movable skatemill belt mounted on the rotating drums and where the working area of the movable skatemill belt is supported by stationary rigid sliding pads with integrated distribution channels for distributing a compressed gas or gas mixtures into the injection openings or slits. The compressed gas or the compressed gas mixture optionally enriched with an anti-friction medium in the form of a vapor or aerosol or dispersion containing solid dust particles or solid microparticles is injected through the inlet openings. By means of the anti-friction applicator, the anti-friction medium is applied to the movable skatemill belt, which then transports the medium to the points of contact with the fixed rigid sliding pads. Stationary solid sliding pads can be cooled down by liquid and/or gaseous cooling medium circulating by default in the hollow support beams of the stationary solid sliding pads.

A powered spinning training/therapy apparatus for rotating a body of a person comprises a spinning apparatus. The spinning apparatus includes a chassis and a rotatable platform supported by the chassis for rotation about a vertical platform axis. The rotatable platform is configured to support the body of the person in an upright orientation with the vertical platform axis passing through the body of the person. A drive unit is operatively connected to the rotatable platform for rotating the rotatable platform about the vertical platform axis and has sufficient power to rotate the rotatable platform and the body of the person disposed thereon at a rotational speed of at least 0.1 RPM. A controller is provided for controlling the drive unit and thereby controlling the rotation of the rotatable platform.

A physical training system includes a belt having a belt attachment member and a first band attachment loop for an elastomeric belt. The belt attachment member is moveably positioned on the belt and at least partially encircles the belt. The belt attachment member comprises a first portion and a second portion, the first portion extending completely across a width of the belt on the outer side of the belt, and the second portion extending at least partially across the width of the belt on the inner side of the belt. The first band attachment loop is moveably connected to the belt attachment member. The elastomeric band extends through the first band attachment loop. A foot coupling includes at least one flexible strap and a second band attachment loop. The elastomeric band extends between the foot coupling and the belt attachment member.

An apparatus for receiving one or more activity attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a circular aperture for receiving an accessory of a set of accessories. Each accessory of the set of accessories providing an activity for a user of the activity. Each accessory having an attachment platform configured to attach the accessory to the board. The attachment platform having a locking mechanism to engaging with a complementary locking mechanism of the board.

A balance board system and associated components incorporating a standard skateboard deck or any other shaped board that allows the user to balance in more than one rotational degree of freedom and can be used on a wide variety of surfaces. The balance board system includes a roller with flexible outer layer, one or more removable stops, and employs the use of a skateboard deck or similar structure as the balance board.

A skating training device comprising; a base adapted to be secured to a surface; said base comprising a shaft located at a center point on the base and extending perpendicularly therefrom; at least one rod having a cross-section and a first and a second opposite extremities, said rod being rotatably connected to the shaft and extending radially outwardly from said shaft and adapted to rotate around said shaft; and a movable rod support comprising a top section and a bottom section, said top section adapted to be secured along the length of the rod, when the device is in use, said bottom section of the movable rod support is in contact with the surface, wherein the placement of the movable rod support along the length of the rod determines the height of the second extremity of the rod where a user will grasp the rod.

A physical training system includes a belt having a back attachment member and a first band attachment loop for an elastomeric belt. The back attachment member is moveably positioned on the belt and at least partially encircles the belt. The back attachment member comprises a first portion and a second portion, the first portion extending completely across a width of the belt on the outer side of the belt, and the second portion extending at least partially across the width of the belt on the inner side of the belt. The first band attachment loop is moveably connected to the back attachment member. The elastomeric band extends through the first band attachment loop. A foot coupling includes at least one flexible strap and a second band attachment loop. The elastomeric band extends between the foot coupling and the back attachment member.

This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

A digital video ramp assembly incorporates process-formed structural LED tiles with modular components that join in a system of scalable structural LED tiles forming a complete LED display structure with integrated LED embedded tiles with interlocking and inter-trans-positioning features sometimes requiring additional structural framing.

A skate spinner comprises a platform configured for a user's foot to be placed thereon, and a support unit forming a lower part of the platform contacting a ground surface and having a curved protruded surface starting from a front end to a rear end thereof. The support unit includes plates each having a thickness equal to at least a thickness of an ice-skate blade and being aligned in a lateral direction of the skate spinner at a predetermined distance. An overall bottom surface of the plates contacting the ground surface has a spherical surface outline.
