大运动量训练对排球运动员淋巴细胞亚群的影响

The Effects of Heavy Load Training on Lymphocyte Subpopulations in Male Volleyball Players

本文研究了大运动量训练对上海男子排球运动员ＮＫ细胞活性和淋巴细胞亚群分布的影响。结果指出大运动量训练后即刻ＮＫ细胞活性显著地低于训练前测定值（Ｐ＜０．０１），运动后１小时及１５小时ＮＫ细胞活性恢复到了训练前水平。Ｔ３（ＣＤ３）和Ｔ８（ＣＤ８）淋巴细胞百分数在运动不同时期均无显著改变，但Ｔ４（ＣＤ４）淋巴细胞百分数在运动后１小时及１５小时显著地低于训练前水平，因而ＣＤ４／ＣＤ８细胞比率也相应地显著降低，至于大运动量训练对细胞免疫功能影响的机理有待进一步研究。

The study included the effects of both 200 minute heavy load training session and 6month heavy load training on NK cell activity and lymphocyte subpopulations in male volleyball players.The results indicated that absolute numbers of white blood cell,neutrophils and lymphocytes of the athletes immediately after 200 minute heavy load training session were significantly higher than pre-training levels,and so was 1 hour after the training session.The percentage of lymphocyte obviously decreased.NK cell activity decreased (p<0.01) immediately after 200 minute heavy load training session.To compare with pre-training and 1 hour post-training levels,all of the pre-training values were re-established in 6 week periodic training.T3(CD3)lymphocyte and T8(CD8)lymphocyte did not change siginificantly in the whole test,but the percentage of T4(CD4)lymphocytedecreased strinkingly 1 hour after the training session and so was in 6 weeks.A significant decrease of the CD4/CD8 ratio was observed.How these results could explain the modifications of immune function remains to be studied.
