Equipment for muscular strengthening and rehabilitation in water

Abstract

Equipment for muscular strengthening and rehabilitation in water comprising a mass of spongy material made of polyvinyl foam preferably with a substantially closed ring annular shape, with a central coaxial through hole. In a preferred embodiment of the invention the above-mentioned ring has a thickness ranging from 2 cm to 5 cm, an external diameter ranging from 9 cm to 15 cm and an internal diameter ranging from 4 cm to 5 cm. Preferably, the inner surface of said ring has an irregular profile. In a different embodiment the equipment has a prismatic shape, substantially parallelepipedal, provided with two large opposite frontal surfaces, substantially rectangular, separated by at least four lateral surfaces, each smaller than one of said frontal surfaces, and comprises two open through cavities on said pair of frontal surfaces. Preferably, the above-mentioned parallelepiped has a length ranging from 9 cm to 15 cm, a width ranging from 9 cm to 15 cm and a thickness ranging from 2 cm to 5 cm. In a further embodiment the equipment has the form of a dumbbell, substantially comprising a section of tube provided on each end with a polyvinyl annular element.
