Abstract: In order to exploit the resource of corn-peptide, the antifatigue effect of corn-peptide was studied. The effects of corn-peptide on the time of swimming and climbing pole on mice thus were observed. And the effects on the content of the plasmaurea, liver glycogen and muscle glycogen were stutied. Corn-peptide enforced the swimming durability of mice and prolongedthe climbing pole time. The contents of the lactates and the plasma urea were lower, but the contents of liver glycogen and muscleglycogen were higher. Corn-peptide has antifatigue effect.

Key words: corn-peptide, antifatigue
