HYPOXIC CHAMBERS - THE USE OF HVAC SYSTEMS IN PROVIDING SPECIFIC TRAINING CONDITIONS OF ATHLETES

Angelika Mularz, Andrzej Pieta

Abstract

Hypoxic chambers represent a significant advancement in simulating high-altitude conditions for athletic training, medical therapy, and physiological adaptation. Originating from HVAC technology, these controlled environments reduce oxygen concentration or atmospheric pressure to replicate elevations up to 6,500 meters, enabling users to train or adapt without leaving sea level. This paper outlines the physiological basis of hypoxia—oxygen deprivation in tissues—and explores its applications, including hypoxic training, intermittent hypoxic therapy, and the use of hypoxic tents. Various technological methods for generating hypoxic air are examined, such as nitrogen membrane separation, pressure swing adsorption (PSA), synthetic gas mixtures, and hypobaric simulation. Each approach is evaluated for its operational efficiency, environmental impact, and technical limitations. The environmental considerations of hypoxic chambers, particularly the use of refrigerants and electricity, are discussed within the context of EU and global regulations, including the F-gas Regulation and the Montreal Protocol. While these chambers offer great potential for performance enhancement and acclimatization, their further development must balance functionality with ecological responsibility, encouraging innovation in sustainable HVAC solutions.
