Intermittent Hypoxic Training (IHT) involves breathing air with reduced oxygen concentration levels (hypoxia) for short periods of time, typically in the range of 1-5 minutes, followed by breathing normal air (normoxia)or higher levels of oxygen (Hyperoxia) for a similar period of time.
Research has shown that IHT produce a range of beneficial physiological adaptations in our body that potentially promote improvement in our immune function, increased anti-oxidant production, enhanced metabolic function, improved glycemic control as well as better blood flow and breathing (Singh 1977, Larsen, Hansen et al. 1997, Lee, Chen et al. 2003).
