ABSTRACT:
A non-allergenic resistive exercise device is described. The device is in the form of a relatively thin elongate band of thermoplastic elastomer. In one embodiment of the invention, the device is in the form of a seamless endless band, while in another, the band is substantially strip-shaped. The bands can be textured to enhance the ability of a user to grip them during use, and the bands can also be printed or otherwise ornamented. The exercise devices of the instant invention are latex-free so as to be non-allergenic, do not require supplemental powdering of their surfaces, and are virtually odor-free. Several methods for producing the bands are also described. In one method, the thermoplastic elastomer material is extruded through an elongate-shaped die to form a cast film, which is solidified and cut to the desired length for use. In this method, the die in desirably substantially dog bone-shaped, in order to produce elongate bands having thickened side edges. In another method, the material is extruded as a hollow tube which is inflated with a gas and enlarged to form a large diameter tube having relatively thin walls. The tube is then cut transversely to form a plurality of seamless, substantially ring-shaped bands.
