Changes

Being exposed to low oxygen for short periods has been shown to provide additional benefits beyond other [[Altitude Training Approaches]]. The technique usually involves [[Breathing]] air with reduced oxygen content for shorter periods. IHE can provide the increase in red blood cell count as longer periods, as well as improving oxygen delivery to the [[Muscle|muscles]]. IHE is normally performed at rest rather than when training, and uses a [[Pulse Oximeter]] to verify the impact of the hypoxia. Also, IHE uses lower oxygen content than other forms of altitude training. For details of the supporting studies for IHE, see [[The Science of Intermittent Hypoxic Exposure]]. It is also possible to exercise while exposed to lower oxygen levels, referred to as [[Intermittent Hypoxic Training]].
