Training device having immediate training effect in water for swimmers

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. Shape of the gaseous medium is very responsive to propulsive forces during underwater part of a stroke. The gaseous medium deformations by water streams/flows cause feedback to swimmer hand, arm, and brain about applied forces. Interactive perception of water through the vanishing gas support assists swimmer to find right mechanics and dynamics of strokes that correspond with the current factors influencing swimming. In other words the device assists in development of human physical qualities required for increase in efficiency of applying hand's (or arm's) force during underwater part of strokes. A sportsman recalls the developed mechanics and dynamics right after workout with the device and its doffing.

1 ) A device for training in water comprising:
 a) at least one shell for air or other gas,   b) said shell is made from elastic material,   c) said shell is worn on inner side of human hand or inner side of hand and forearm,   d) said shell has at least one valve,   e) said shell changes its volume and, or, mechanical strain of elastic material due to pressure changes,   f) said shell is attached to inner side of hand or hand and forearm by a material embracing hand or hand and forearm of swimmer or sportsman during strokes in water.   
     
     
         2 ) The embracing material of  claim 1  is made from the same material as the said shell. 
     
     
         3 ) The embracing material of  claim 1  has a mitten like form. 
     
     
         4 ) The embracing material of  claim 1  embraces the entire surface of hand or hand and forearm with fingers serried together. 
     
     
         5 ) The embracing material of  claim 1  embraces the entire surface of hand or hand and forearm with each finger separately. 
     
     
         6 ) The embracing material of  claim 1  has insertions like bands, clasps, fasteners, zippers, hasps, snaps, hooks, velcro. 
     
     
         7 ) The shell of  claim 1  has separate chambers for creating positive pressure.
