Objective To study the effects of Ginkgo biloba extract (GBE) on free radical metabolism of different fiber types of quadriceps in exercised rats and its mechanism. Method Increasing load exercised rat model was selected. The test rats were orally given GBE aqueous suspension (100 mg/ kg?d), and the controls with water. The levels of malondialdehyde (MDA) and the activities of total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px) of red muscle, white muscle and whole quadriceps of exercised rats were examined before exhaustive exercise, at instant,24h and 48h after strenuous exhaustive exercise. Results Compared with the controls,MDA contents were 49.69% higher in white muscle (P
