Intermittent hypoxic therapy, also known as intermittent hypoxic training (IHT), is a technique aimed at improving human performance by way of adaptation to reduced oxygen. An IHT session consists of an interval of several minutes breathing hypoxic (low oxygen) air, alternated with intervals breathing ambient (normoxic) or hyperoxic air.
The term hypoxicator was suggested by Russian scientists in 1985 to describe a new class of devices for Intermittent hypoxic training (IHT) – an emerging drug-free treatment for a wide range of degenerative disorders and for simulated altitude training used to achieve greater endurance performance [3] as well as offering pre-acclimatisation ...
Intermittent hypoxia (also known as episodic hypoxia) is an intervention in which a person or animal undergoes alternating periods of normoxia and hypoxia. Normoxia is defined as exposure to oxygen levels normally found in Earth's atmosphere (~21% O 2 ) and hypoxia as any oxygen levels lower than those of normoxia.
In the developed world, the most frequent type in use is the continuous-flow anaesthetic machine or "Boyle's machine", which is designed to provide an accurate supply of medical gases mixed with an accurate concentration of anaesthetic vapour, and to deliver this continuously to the patient at a safe pressure and flow.
HTi : Hypoxic Training index, t : period of time, and SpO2 (t) : SpO2 (%), arterial oxygen saturation value measured at one-second intervals. How the HTi is calculated: Only part of the IHT session is shown, the targeted SpO2 value is 80% as an example. The filled part of the SpO2 graph represents the amount of hypoxia delivered, “dosage”.
The Buteyko method emphasizes the role of carbon dioxide and hyperventilation in respiratory diseases as well as overall health. It is known that hyperventilation can lead to low carbon dioxide levels in the blood (or hypocapnea), which can subsequently lead to disturbances of the acid-base balance in the blood and lower tissue oxygen levels.
Mild, non-damaging intermittent hypoxia is used intentionally during altitude training to develop an athletic performance adaptation at both the systemic and cellular level. [5] Hypoxia is a common complication of preterm birth in newborn infants. Because the lungs develop late in pregnancy, premature infants frequently possess underdeveloped ...
Hypoventilation training is a physical training method in which periods of exercise with reduced breathing frequency are interspersed with periods with normal breathing. The hypoventilation technique consists of short breath holdings and can be performed in different types of exercise: running, cycling , swimming, rowing , skating , etc.
