The invention relates to sports apparatuses with unstable surface intended for improving and maintaining ones physical condition. The sports apparatus according to a first embodiment comprises a flexible shell formed as a hermetic chamber with a valve and having an inner space for filling with a filler material and/or air. The hermetic chamber is accommodated within a case with handles. Once the chamber inner space is filled with a filler material and/or air, the sports apparatus in fact forms a rectangular parallelepiped with rounded corners. Side faces of the apparatus form a closed surface. The side face has a height not exceeding a half of the apparatus length. A supporting portion of the apparatus and a portion that the user interacts with are arranged to be identical and outwardly convex. The sports apparatus in operating condition has an elliptical cross-section. Said sports apparatus portions are unstable surfaces.

A wearable massage and/or compression device for applying controllable scrolling or intermittent sequential forces, such as compression forces, to the body and limbs of a user comprises an elongated fabric body sized to encircle a limb of a user, one or more shape-memory wires carried by the fabric body and configured to apply a compression pressure to the limb through the fabric body upon changing shape in response to a stimulus, and a micro-processor based controller for selectively actuating the one or more shape-changing elements to reduce the effective diameter of the device encircling the limb, to thereby apply pressure to the limb.

An immersive upper limb rehabilitation training system includes a dual-arm rehabilitation robot, a base, a position tracker, a VR headset, a force-feedback glove, a host computer control center and passive compliant end-effectors. The dual-arm rehabilitation robot is mounted on the base, and drives an arm of a patient to move through two passive compliant end effectors. The visual sensor is used for recording a motion of an upper limb of the patient and feedback-controlling a motion of the dual-arm rehabilitation robot. The position tracker is used for real-time collecting position and posture information of the arm and transmitting it to the upper computer control center. The two passive compliant end-effectors are respectively worn on a forearm and an upper arm of the patient. The upper computer control center is used to provide a quantitative index and control a display of a training screen.

A relief system for at least partially relieving the body weight of a person includes at least one first fastening device for fastening a first end of a first support device and at least one second fastening device for fastening a second end of the first support device which are formed on a cuff, such that an equally distributed tensile force is exerted on the cuff at the first fastening device and second fastening device when the first support device is guided through a guide device during a movement of the cuff when loaded by at least part of the body weight of the person. This advantageously permits a simple connection in particular of a bedridden patient to the relief system, without the patient first having to be moved, without other medical/therapeutic devices being disturbed, and without limiting the patient's stepping/walking movement.

A golf system comprising a reconfigurable golf green having a hole for receiving a golf ball, wherein the reconfigurable golf green includes a plurality of movable golf green sections (e.g. wherein the movable golf green sections are provided in a reconfigurable array).

A portable inflatable golf studio including an arcuate shaped roof panel, first and second side panels, a floor panel, a front panel, a back panel, a projector screen, a projector, and a tracking system. The first and second side panels are positioned parallel from one another and are attached to the arcuate shaped roof panel, wherein one of the first and second side panels defines a cavity configured to receive a television monitor. The floor panel configured to connect the first and second side panels to one another. The front panel removable attached to the arcuate shaped roof panel and the first and second side panels. The back panel positioned parallel to the front panel and attached to the arcuate shaped roof panel and the first and second side panels. Each panel includes one or more of inflatable sections.

An exercise and therapeutic device includes a treadmill comprising a running belt coupled to a treadmill frame and an offloading system coupled to the treadmill. The offloading system includes an air chamber surrounding the running belt adapted to be selectively inflated between a deflated condition and an inflated, operating condition, a user seal coupled to the air chamber, adapted to receive a user so that, in an operating condition, at least a portion of a user is received in the user seal and positioned within the air chamber and to seal the air chamber around the user, a pump operable to inflate the air chamber, at least one strap coupled to the treadmill frame and adapted to restrict the expansion of the air chamber and adjust a spacing of the user seal relative to a running surface of the running belt when the air chamber is inflated.

Protector for an American football player, including, as impact absorption device, an inflatable element defining an inner chamber adapted to receive an inflation fluid and adapted to assume an active inflated condition. Use of an inflatable element as a protector for an American football player and a method for protecting an American football player are also described.

(Problem)

The invention is object to provide a training belt, in which the loop band sold conventionally and generally can be used, and in which a plurality of loop bands are provided in a simple structure, and in which moreover, it can be connected easily in arbitrary length, and in which the cost and time can be reduced, and convenient also to carrying.

(Resolution Approach)

The invention is a training belt, comprising, a plurality of stretchable belt members 12 having loop shape, an intermediate engaging member 14, in which the plural of the belt members 12 are detachably coupled mutually, a first engaging member 20, which is detachably coupled to the one edge of the belt member 12 that is coupled by the intermediate engaging member 14, and a second engaging member 38, which is detachably coupled to the other edge of the belt member 12 that is coupled by the intermediate engaging member 14, wherein the training belt becomes a loop shape by engaging the first engaging member 20 and the second engaging member 38.

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.
