The evolution of simulated altitude training chambers are becoming commonplace in commercial gyms. What is altitude training versus simulated altitude training? Is simulated altitude training SAT suitable for everyone? Traditionally, altitude training involved travelling to venues around the world that are located 1800m or move above sea level to take advantage of changes in the environment to stimulate accelerated responses to exercise. This traditional approach of training was and still is used by athletes who were endeavouring to improve performance through changes in the oxygen-carrying capacity of their blood to increase VO2max. There is a well-recognised measure of aerobic endurance capacity. The air we breathe at sea level is roughly 79% Nitrogen 20.9% oxygen and a mix of smaller gasses. Fundamentally, simulated altitude training (SAT) involves reducing the amount of oxygen in the room to mimic the terrestrial altitude environment. The evolution of SAT chambers that are now becoming commonplace in commercial gyms and training centres have provided an opportunity for everyone to experience the benefits of exercising in a low oxygen environment. As a general rule, SAT is a suitable form of training for most populations. However certain populations should obtain a medical clearance prior to undertaking exercise in a SAT chamber. For example, anyone taking any prescribed medication that may have an impact upon exercise has current injuries or a known or suspected cardiovascular, pulmonary, neurological, metabolic or musculoskeletal conditions. Caution should also be taken during pregnancy, with children and anyone demonstrating signs or symptoms of an acute illness such as colds and flu. 14 In the absence of the aforementioned circumstances that require medical clearance prior to undertaking SAT, whether an individual is exercising to decrease body fat, improve lean muscle mass, increase their endurance or improve their exercise capacity, then simulated altitude training is a suitable option for most people. Should a pre-assessment be undertaken prior to embarking on altitude training and if so, what should it involve? Yes, anyone commencing an exercise programme for the first time, or if they have not exercised in a SAT chamber previously should undertake a pre- assessment to ensure they get the most out of their program. Individuals with pre-existing medical conditions or taking any prescribed medication that may have an impact upon exercise should speak to their general practitioner and obtain a clearance where required. A pre- screening assessment should include a pre-exercise questionnaire known in the fitness industry as a physical activity readiness questionnaire (PAR-Q). In addition to the adult pre-exercise screening tool developed by Exercise and Sports Science Australia (ESSA) as part of the pre-screening process, individuals should also undertake a passive exposure test, followed by an active altitude tolerance test that involves an incremental exercise regime to determine an individual’s response to the SAT environment.
