The thesis aimed at investigating the effects of Ligustrum lucidum extracts on different organizational activities of exhaustive exercise in rats,its antioxidant and the possible mechanisms of improving the body's resistance to fatigue.The experimental model of increasing endurance treadmill training in rats,was established,and the exhaustive time,antioxidant enzyme activities and GSH content in rats were measured.The results showed that Ligustrum lucidum extract increased copper,zinc superoxide dismutase(Cu-Zn-SOD),manganese superoxide dismutase(Mn-SOD),glutathione peroxidase(GSH-Px) activity and reduced glutathione(GSH) content of different organizations in exhaustive exercise rats.Supplementary with Ligustrum lucidum extracts significantly increased antioxidant enzyme activity,reduced lipid peroxidation damage caused by exhaustive exercise and lipid peroxidation of organization in rats,and played a good role in improving athletic capacity in rats.
