This study was aimed to evaluate the effect of saengmaeksan on the recovery of exercise induced fatigue. In this experiment, white rats were divided into 2 groups; control group and Saengmaeksan treated group. The results were as follows: 1. Oxygen consumption was significantly decreased in Saengmaeksan treated group than in control. 2. Serum lactate levels were significantly decreased in Saengmaeksan treated group than in control. 3. Serum LDH activities were significantly decreased in Saengmaeksan treated group than in control. 4. Serum triglyceride levels were significantly increased in Saengmaeksan treated group than in control. 5. Serum glucose levels were significantly increased in Saengmaeksan treated group than in control. 6. Serum FFA levels were significantly decreased in Saengmaeksan treated group than in control. According to the results, saengmaeksan showed remakable effects in the recovery of exercise induced fatigue.
