Title:
PERSONAL BREATHING APPARATUS FOR TRAINING ATHLETES
Document Type and Number:
WIPO Patent Application WO2000054854
Kind Code:
A3
Abstract:
An apparatus is described for use by an athlete during training exercise. The apparatus comprises a supply (10) of pressurised gas that consists of air depleted in oxygen, a flow regulating and limited valve (12) for setting the rate of discharge of the gas from the supply, and a discharge pipe (14, 15, 16) for delivering a concentrated stream of the gas towards the vicinity of the athlete's face to form a localised oxygen depleted region near the mouth and nose. In use, the athlete breathes in parallel stratified streams from the oxygen depleted region and from the ambient air, the separate inhaled streams resulting in the lungs receiving a lower average oxygen concentration than the ambient air surrounding the athlete.
