At present, the altitude training has been widespread concerned in the sports scientific community sports and has been achieved remarkable development as a effective approach to enhance the athletes score. At the same time, a large number of data indicate that hypoxic environment is very useful in treating and restorating the patients with asthma, hypertension, and myocardial infarction. It has attracted interest to applicate artificial hypoxic conditions in exercising. Taking exercise in artificial hypoxic condition can guarantee to reach the best and effective results. Therefore, using hypoxic conditions for fitness or treating, preventing of diseases has become an important method of non-drug treatment to promote.
