Abstract: In order to explore the effects of exercise training on the immunity, the T-lymphocyte subsets in peripheral blood were measured after exercise training with different loads for 8 weeks. The results: After exercise training, CD3+ T-lymphocytes were no significance among the three groups. In 1 h training group, CD4+ cells were higher than those in control group significantly. Compared with control group, CD8+ cells had a decrease tendency, but there was no significant difference. The ratio of CD4+ and CD8+ was higher than that on control group significantly. In exhaustive training group, CD4+ cells were lower than those in 1 h training group significantly. Compared with control group, it had a decrease tendency, but there was no significant difference. CD8+cells were higher than those in control group and in 1 h training group. The ratio of CD4+ and CD8+ was lower than that in 1 hr training group and in control group significantly. The results suggested that moderate exercise training improve
