高住低练对游泳运动员红细胞免疫黏附功能及白细胞计数的影响

Effects of HiLo for two weeks on erythrocyte immune adhesion and leukocyte count of swimmers

目的:了解高住低练对高水平游泳运动员血细胞天然免疫功能的影响。方法:6名女子游泳运动员进行2周高住低练,训练前、训练期间及恢复1周分别测试红细胞黏附功能、白细胞计数指标。结果:训练期间运动员红细胞C3b受体花环率(RBC-C3bRR)明显下降(P<0.05),红细胞免疫复合物花环率(RBC-ICR)明显上升(P<0.05),恢复1周后指标回归正常;白细胞、粒细胞在训练期总体上呈显著性下降(P<0.05),训练结束1周后恢复;单核细胞和淋巴细胞训练期间总体趋势是下降,训练结束1周后仍未恢复。结论:红细胞和粒细胞的天然免疫功能下降快,恢复快,但淋巴细胞、单核细胞计数恢复较慢,运动员对本次训练基本适应。

Objective： To investigate the effects of living high-training low（HiLo） on innate immunity in blood of elite swimmers. Methotis： Six female swimmers undertook HiLo for two weeks, erythrocyte adhesion function and counts of leukocyte were tested in different time of training period. Results： Red blood cell C3b receptor ring rate （RBC-C3bRR） decreased and red blood cell immune complex matter ring rate （RBC-ICR） increased significantly（ P 〈0.05） ,the two markers returned to base line 1 week after training. Counts of leukocyte and granulocyte decreased significantly （ P 〈 0.05）, and they recovered 1 week after training; Counts of lymphocyte and monocyte decreased without significance during training and did not recovered after training. Conclusion： Immunity of elythrocyte and granulocyte decreased and recovered quickly, but lymphocyte and monocyte recovered slowly, swimmers were adaptive to the training.
