Abstract: During exercising the fat metabolism rate increases as exercise intensity increases, and decreases after it reaches the maximum value; the intensity corresponding to the fat metabolism peak value within a unit time is called maximum fat metabolism intensity (Fatmax), and such a peak rate is called maximum fat metabolism rate (Fatmax Rate). The authors gave an overview of the test methods and affecting factors of Fatmax as well as the appli-cation of Fatmax in practice, and concluded that this index has important realistic significance in stamina training and working out programs for weigh reduction and prescriptions for healthy exercising. The purpose of this article is to provide a referential criterion for people to select more effective exercise intensity for weight reduction and fitness promotion.
