The author revealed the following findings: 1) in a calm condition, the immune indexes of excellent rowers were significantly lower than the normal values, meaning that the immune functions of the rowers decreased significantly after high intensity professional training over a long period of time; 2) immediately after the race, the WBC counts and subsets increased significantly, but the subsets had unequal in-crements; 3) 3 h after the race, all the levels of lymphocytes, intermediate cells, immunoglobulin and complements decreased significantly and got close to or reached the levels before the race, but on the contrary the level of neu-trophilic granulocytes increased greatly, which promoted only slight decreases of the WBC counts and caused sig-nificant changes of the subsets once again; 4) 24 h after the race, most immune indexes had basically recovered to the levels before the race, but the levels of intermediate cells, lymphocytes and C4 had extent different increases on the bases recovered 3 hours after the race, which may be related to different moving directions, biological functions and adjusting mechanisms of 3 WBC subsets.
