The purpose of the present study is to investigate the effects of a month's administration of silk amino acid on lactic acid, blood energy substrates and hormones in 10 male college students. Exercise protocol was tread-mill exercise of VO2max 60~65% for 60min. The results of research were as follows. Lactic acid concentration of post-exercise was significant higher than pre-exercise(p<0.05). In concentration of energy substrates, glucose was no changed. but triglyceride was significantly increased after exercise(p<0.05). Also, Total-cholesterol, HDL and LDL were significantly increased post-exercise(p<0.05). A month's intake of silk-amino acid did not make change in the concentrations of plasma leptin and dopamine post-exercise, but norepinephrine(p<0.01) and serotonin(p<0.05) were significant higher post-exercise than pre-exercise. In conclusion, this results indicated that supplement of silk amino acid showed any positive effects during the submaximal exercise.
