The higher in the mountains, the lower the air pressure will be and as a result fewer oxygen molecules are present on the same surface. This means that you inhale less oxygen on top of a mountain than at sea level. Getting less oxygen stimulates the body to adapt to this new situation. Over time, there are therefore various systems such as breathing, blood transport (number Red blood cells) and the oxygen uptake in the muscles improved considerably. Result: General fitter level and better performance in daily life and at top sport level.
The altitude tent uses this process and uses the same oxygen-poor air as if you were standing on top of a mountain in your home. The altitude generator removes a small percentage of oxygen from the normal air and pumps the remaining oxygen-poor air into the height tent. The separation of a percentage of oxygen with the rest of the air is done via a variant of the complex 'pressure swing adsorptionmethod. The air pressure remains exactly the same at every height.
