Abstract
An infinitely adjustable training mask for simulating the increased breathing resistance level at higher altitudes including an air-impermeable mask body covering the nose and mouth of the wearer, an infinitely adjustable inhalation resistance assembly extended through the mask body, a replaceable particulate air filter to provide respiratory protection when the wearer inhales, and a drinking device for hydration and consumption of foods. The inhalation resistance assembly contains a stationary aperture component and a rotating dial aperture component for adjusting the sizes of the overlapping inhalation adjustment apertures to achieve the desired breathing resistance level. Upon exhalation of the wearer, the exhaled air is discharged through a flexible one-way check valve controlled exhalation channel. A replaceable particulate air filter which can be easily placed inside or removed from the internal cavity of the infinitely adjustable inhalation resistance assembly helps to reduce inhalation exposures to airborne particles during outdoor training sessions. The drinking device enables the wearer to conveniently hydrate or consume foods without taking the mask off, thus allowing maximum amount of wear time to improve training efficiency. A strap is connected to the mask body to be positioned about the head of a wearer to securely maintain the mask during training.
