Abstract: Neuroglobin (Ngb) is a newly discovered particular oxygen carrying globin in the nervous system, mainly expressed in the brain tissues of vertebrates at a high level, closely related to oxygen supply in brains. It is indicated in researches that hypoxia can induce the expression of Ngb, while Ngb expressed at a high level can pro-tect neurons from being damaged by hypoxia, thus it is provided with an important nerve protecting function in nervous system damages caused by hypoxia or ischemia. By studying the biological characteristics of Ngb, the au-thors gave an overview of the current situation of Ngb study in medical science, and expected the application of Ngb in sports science.
