Abstract:With Kunming white mice as experimental animals，the mice were gavaged with tartary buckwheat bioactive peptide beverage.After 30 days，loaded swimming experiment was conducted to detect loaded swim－ming time，content of blood lactic dehydrogenase，urea nitrogen，lactic acid and hepatic glycogen.Using the same method，anti-oxidative experiment was conducted to detect the content of total antioxidant activity and SOD activity in liver.Compared with the control group，the loaded swimming survival time of Kunming white mice injected with tartary buckwheat bioactive peptide beverage was prolonged obviously，the content of serum lactic acid and urea nitrogen was decreased effectively，and the content of hepatic glycogen and lactic dehydrogenase was increased after the loaded swimming.In the anti-oxidative animal experiment，it was found that the level of total antioxidant activity and SOD activity in liver of mice could be increased by tartary buckwheat bioactive peptide beverage.Effects were more obvious with the increasing of dosage.Due to good anti-fatigue and anti-oxidative effects，tartary buckwheat bioactive peptide beverage can be developed to be health beverage with anti-fatigue and anti-aging effects.
