This study was designed to investigate the effects of supplementing soy peptide on isometric performances and serum CK and LDH trends after a high intensity eccentric exercise stress. Study subjects consisted of 13 males and were divided into 2 groups. They were instructed to take 4,000mg of soy peptide or placebo orally before and for 7 days following the initial exercise stress. Soy peptide group revealed significantly faster improvements in knee extension performance at 72 hr-post the eccentric exercise (p<0.05). Comparing with placebo group, soy peptide group showed significantly lower serum LDH activity 168 hr after the exercise (p<0.05), while as to serum CK levels, significant difference was not observed between those 2 groups. These results indicate that oral supplementation of soy peptide could induce not only reduction in serum LDH activity level, but also faster recovering in isometric performance after high intensity repetitive eccentric exercise.
