==Altitude Training Approaches==There are A comparison of various ways of using approaches to altitude to improve performancetraining. ===Live High, Train High===By moving to altitude, you are exposed to lower oxygen all the time. While this approach can have a good effect on altitude acclimatization, it makes training much harder. Therefore the benefit of altitude on increased red blood cell count are offset by the reduced ability to train hard. There is also evidence that LHTH reduces muscle mass<ref name="muscle"/>. ===Live High, Train Low===Sleeping at altitude produces the increase in red blood cells, and training at low altitude provides optimum training benefits. This effect can be achieved by literally living at a high altitude and travelling to a lower level to train. However, this approach is also possible by using a hypoxia generator to reduce the level of oxygen in a tent. The downside to an altitude tent is that the quality of sleep can be significantly degradedand the equipment is expensive. ===Intermittent Hypoxic Training===Being exposed to low oxygen IHT uses lower O₂ concentrations than LHTH or LHTL, but for short shorter periods has been shown to provide additional benefits beyond other altitude training approaches. The technique usually involves breathing Typical regimes are 5 min hypoxia + 5 min normal air with reduced oxygen content for shorter periods IHT can provide the increase in red blood cell count as longer periods, as well as improving oxygen delivery to the musclesrepeated 6 times.
