Provided herein is a multi-purpose exercise apparatus for improving sports coordination with which a user may sense stimuli from inside and outside one's body and at the same time operate one's body functions so as to adapt to the given circumstances using body muscles when playing a football, volleyball, handball, tennis, table tennis game and the like, thereby improving abilities of adjusting one's body parts such as the user's correct posture, balance, timing, flexibility, agility and the like, especially, significantly improving the ball control technique, body senses, and judgment ability of ball game players or sports participants.

Disclosed is system and method for measuring the tension of a tennis net, and, alternatively or in addition, for determining if a service let occurs via the measuring of the net tension. The disclosed embodiments measure a force exerted on the center-strap or the singles stick by the net. In these embodiments, the measured force provides an accurate reflection of the tension of the net.

An easily assembled and disassembled frame for a net game includes a rigid multi-part frame with a cross-member that is non-sagging. Sections of the multi-part frame have an elliptical profile. A net stabilizer includes a tensioning member coupled at one end to a retention member of the frame, and having the other end of the tensioning member inserted into a center sleeve of the net, and, a center sleeve with a securing member for fastening securely at one end to the cross-member.

The subject of the utility model is a multi-purpose sports apparatus particularly for improving footballers' technical skills, comprising a foundation body (10) containing a playing surface (11) and an obstacle element (20). The distinctive feature of the method is that the playing surface (11) of the foundation body (10) looking from the interior of the foundation body (10) has an at least partially convex top surface (15) and the foundation body (10) has a support structure (30) which separates the playing surface (11) from the base (2).

A tabletop volleyball system for playing tabletop volleyball for sport and entertainment; the tabletop volleyball system having a net having a perimeter, and a mesh, a first-bracket, and a second-bracket. The net is defined by the perimeter and has the mesh within and integral to/with the perimeter. The net is adjustable relative to an existing tabletop tennis table assembly and the net is located on a plane, when installed, above an existing-net for play.

An ultraviolet court-illumination system is used to light a playing court and any related equipment in a fluorescent manner. The system includes at least one playing court, a first plurality of ultraviolet (UV) court lights, a plurality of fluorescent game boundary-markers, and at least one fluorescent game fixture. The playing court is used for playing games or sports. The plurality of fluorescent game boundary-markers is superimposed onto the playing court and is used to delineate the boundaries of the playing court. The fluorescent game fixture is mounted onto the playing court and may be a net, a goal, or any other fixture used to play the sport. Each of the first plurality of UV court lights is peripherally positioned about the playing court and is used to illuminate the fluorescent game boundary-markers and the fluorescent game fixture. The first plurality of UV court lights is powered by a power source.

Provided herein is a multi-purpose exercise apparatus for improving sports coordination with which a user may sense stimuli from inside and outside one's body and at the same time operate one's body functions so as to adapt to the given circumstances using body muscles when playing a football, volleyball, handball, tennis, table tennis game and the like, thereby improving abilities of adjusting one's body parts such as the user's correct posture, balance, timing, flexibility, agility and the like, especially, significantly improving the ball control technique, body senses, and judgment ability of ball game players or sports participants.

A portable exercise apparatus intended for indoor use. A vertical spine is constructed and mounted to a plurality of wall braces. The spine has a series of pairs of hooks aligned vertically. The user can then place either a pulley plate or a body into a desired hook. Hooks are configured such that when the pulley plate or body is placed therein, force in a downward or straight direction would not remove the pulley plate or body. A bench can be attached to the pulley plate or body which then allows a user to set or lie on and perform exercises using a resistance cord which can be connected to the body, pulley plate, and or braces.

A method and apparatus for playing a court game for at least a first player and a second player is described. The court game may have at least a reinforced ball, at least two paddles, and at least one barrier. A centerline divides the playing court. The barrier is configured to allow the ball to pass below the barrier but prevent the ball from passing above the barrier. Using the paddles, players hit the ball back and forth under the barrier. If a player fails to hit or otherwise contact the ball, and the ball hits a wall behind the player, the opposing player scores.

A net boundary indicator can comprise a strap comprising an inside surface and an outside surface opposite the inside surface. A reinforcing member can comprise a top end and a bottom end, the reinforcing member being attached along a length of the inside surface of the strap. A top clip can be coupled to the strap adjacent the top end of the reinforcing member. A bottom clip can be coupled to the strap adjacent the bottom end of the reinforcing member. A first sleeve can be attached along a length of a surface of the strap. An aligning device can be coupled to the surface of the strap below the first sleeve and in-line with the first sleeve, and a bubble level can be coupled to the strap.
