Abstract: Objective: To observe the effects of taurine on movement ability of mice.Methods: The huckle nerves of the mice were stimulated by electric current at different frequency.The contracting capacity of gastrocnemius and the swimming times of the two groups of mice were recorded.The gastrocnemius was stimulated by a fixed single pulse(2 Hz) and 50% of the maximum contracting amplitude was determined as fatigue.Results: The contracting ability of gastrocnemius of the taurine group increased,compared with the control group,and the time of fatigue and swimming endurance clearly extended(P<0.05).Conclusions: Taurine can strengthen mice's movement ability.
