Taurine (2-aminoethane sulfonic acid), a nonprotein amino acid, has hypolipidemic, antiatherosclerotic, and antioxidative effects. In this point of view, twenty-one male Sprague-Dawley rats were used as the subjects. They have fed 40% of high fat diet with or without 15 g/kg of taurine. In addition, they exercise on the treadmill at 27 m/m, 8% of incline for 4 wks. Stored glycogen contents in liver and skeletal muscles were analyzed. In addition. SOD activity and MDA concentration in liver were analyzed. Liver and gastrocnernius muscle glycogen content were significantly increased in taurine supplemented group (p<.05). MDA was significantly decreased in taurine supplemented group (p<.05). And SOD was significantly increased in exercise and taurine supplemented group (p<.05). These results suggested that taurine supplementation before exercise might prevent exercise induced lipid peroxidation and enhance glycogen storage, which might increase exercise performance.
