Objective: The purpose of this study is to reveal the dynamic changes of ascorbic acid( AA) in the striatum and the regulation of extracellular Glu concentration during the development of exercise-induced fatigue,and to further clarify the central mechanism of AA anti exercise fatigue. Male Wistar rats were used as experimental subjects,and divided into AA group( AAT),AA supplement group( AAG) and control group( SG). The changes of extracellular AA concentration in striatum of rats in the process of one-tim...
