Abstract: The purpose of the invention was to develop a training device that allows acquiring sense of water immediately after workouts with it. The possible embodiment comprise an elastic or stretching material with gaseous medium between water and sportsman's palm and (or) forearm, and at least one valve. The embodiment allows to create the artificial gaseous medium at the inner side of human hand and/or forearm in water and to change its pressure and volume. The gaseous medium pressure and volume are set for a sportsman to change his psychosomatic sensations and lead to changes in mechanics and dynamics of the sportsman strokes in water. The invention with gaseous medium assists swimmer to improve his ability to sense water. If pressure of gaseous medium is properly selected there is an effect of vanishing support during execution of strokes. The effect occurs due to properties of fluent gaseous medium in elastic/stretchy material.

Abstract: The inventive breath training device comprises a respiratory tube, a low-frequency mechanical air oscillation generator provided with an oscillation chamber embodied therein and provided with an input channel which is embodied in the form of an upwardly extending saddle-shaped body of revolution, contains a spherical ball and is connected to the respiratory tube and to an output channel communicating with ambient air, wherein the respiratory tube is provided with a jacket in which the body of the low-frequency mechanical air oscillation generator rotatable about a horizontal axis is fixed and a bypass chamber provided with an inspiratory tube is formed, said inspiratory tube comprises an inspiratory valve provided with a tubular attachment and the output channel of the oscillation chamber of the low-frequency mechanical air oscillation generator is also provided with an expiratory valve.
