长时间大强度游泳训练对儿少运动员免疫机能的影响

Effects of Prolonged High Intensity Swimming Training on Immune Functions of Juvenile Swimmers

为研究长时间大强度运动训练对儿少免疫机能的影响 ,选取业余体校 8～ 16岁儿少游泳运动员 2 0名 (全部为男性 ) ,训练年限分别为 3～ 9年 ,测试其在大强度训练期间 :1)外周血T细胞亚群包括CD3 + 、CD4 + 、CD8+ 以及CD4/CD8;2 )外周血NK细胞毒活性 ;3)外周血细胞因子包括白细胞介素 - 1和白细胞介素- 6。结果显示 :大强度运动训练在一定程度上对儿少的免疫系统产生明显的抑制作用。

juvenile male swimmers of 8～16 years old in spare time schools were chosen as the subjects to study the effects of prolonged exercise training on immune functions. They have been trained for 3～9 years, respectively. During the high-intensity exercise training the following indexes were examined. They are the peripheral blood T cell sub-groups including CD 3+ , CD 4+ , CD 8+ and CD 4/CD 8, the cytotoxic activity of NK cells in peripheral blood and the genes in peripheral blood cells including interleukine-1 and interleukine-6. The results showed that the high intensity exercise training produced obvious inhibition in immune systems of juvenile swimmers to a certain extent.
