To a certain extent, resveratrol has the function of eliminating oxidation free radicals increased in training, increases ATPase ac-tivity of the trained rats after high intensity exercising, improves the secretion of NO of endothelial cells, and facili-tates the recovery of erythorocyte functions after high intensity training.
