This is a comparison of the various approaches to [[Altitude Training]], their pros and cons.
==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|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 traveling to a lower level to train. However, this approach is also possible by using a hypoxia generator to reduce the level of O<sub>2</sub> in a tent. The downside to an altitude tent is that the quality of sleep can be degraded even more than living at altitude and the equipment is expensive.
