The results showed: 1) taurine can enhance exercise ability; 2) immediately after ex haustive exercise, LD content and LDH activity in plasma were increased signific antly, muscle glycogen (MG) content in the red muscle and liver glycogen (LG) content in liver were decreased significantly. But having supplied with 1% taurine in drinking water for five weeks, their changes were not significantly. Theresults suggested that taurine had the effect on anti-fatigue.
