Hypoxic training, also known as intermittent hypoxic therapy, is a technique aimed at improving human performance by way of adaptation to reduced oxygen. Procedure An IHT session consists of an interval of several minutes breathing hypoxic air, alternated with intervals breathing ambient or hyperoxic air.

The classic model of altitude/hypoxic training is the live-high train-high (LHTH) approach, where athletes travel for 3–4 weeks to a moderate altitude (generally recommended to be between 2000 and 2500 m) and spend all of their time living and training at this altitude.

When you train in the hypoxic room, you train your body to process red blood cells more efficiently and you increase your aerobic capacity. Your red blood cells will even carry any waste away from your body a lot more quickly when you train under simulated high-altitude conditions.

Exercise training in hypoxic conditions is significantly effective in improving the oxygen-transporting capacity of the blood because it increases the plasma volume and RBC production by EPO and this effect persists for approximately 16 days after exposure to the hypoxic condition.

In both instances, the nature of the risk is clear: possible death. Even with successful resuscitation, complications including hypoxic brain damage and respiratory infection can occur.

Hypoxic training is the idea of training in low oxygen environments, so that your body will learn to create the same amount of energy with a significantly lower amount of oxygen. It trains your body to function more effectively in an oxygen debt.

Some researchers propose that silent hypoxia is linked to the development of pulmonary thrombi formation in COVID-19. 10 11 The respiratory centres are too much sensitive to CO2. On the other hand, hypoxia produces dyspnoea by stimulating carotid bodies, which in turn send signals to the medulla oblongata.

New research from Japan has demonstrated the role of hypoxia in muscle growth, and shown that exposing muscle cells to low oxygen conditions can increase muscle growth compared to normoxia. Researchers have long shown that one of the important stimuli for muscle growth is local hypoxia.
