Abstract: Fatigue state will affect human body function and thinking judgment, which will easily lead to military training injuries and thus reducing the combat ability of troops. At present, there still lacks a perfect evaluation system for military exercise-induced fatigue, and it is urgent to develop a fatigue evaluation system that is suitable for military training. This article reviews the mechanism of military exercise-induced fatigue and the commonly used methods for fatigue evaluation in China and globally, so as to provide a reference for evaluating and monitoring fatigue during military training.
