The invention refers to the equipment of the training rink for floorball, manufacturing of exerciser structural element, applying concept of tennis racket stringing. Proposed design of subsidiary element for floorball rink arrangement characterised with that it is made as latticework formed by: two parallel end plates; several threaded rods as stiffening members; two elastic string structures disposed in two parallel planes, at that each of it presents one side of mentioned latticework and provided with: —holes for fastening threaded rods which assure rigidity and load bearing capacity of the subsidiary element frame structure; —holes for criss-cross stringing in two parallel planes and string fastening at mentioned end plates independently one from another.

Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

A retrieval apparatus attaches to the handle of a paddle, thereby enabling the user to retrieve pickleballs, with minimal bending. The apparatus comprises a hook and a base. The base has a first half and a second half. The hook has a stem in an L-shape when the apparatus is mounted on the paddle and the paddle is held upright, a curved body, and an end-point. The end-point is angled at least 30 degrees relative to the horizontal plane of the stem. The second half of the base includes various attachment mechanisms for securing the apparatus to a paddle handle, which include: an affixed channel with a snapping mechanism, a breathable slit, an adhesive, or a form-fitting sleeve.
