| （广东外语外贸大学 体育部，广东 广州 510420） 摘 要：为探讨体育舞蹈锻炼对大学生血清免疫球蛋白及T淋巴细胞亚群的影响。随机抽取广东外语外贸大学公共体育课一年级体育舞蹈选项课学生男女各16名作为实验组，每周进行3次体育舞蹈锻炼，每次40 min，训练强度控制在心率为135~150 次/min，持续10周；另外选择一年级男女学生各16名作为对照组，不进行体育舞蹈锻炼；所有研究对象在实验前和结束后次日晨在同一时间空腹抽肘静脉血测量血清免疫球蛋白和T淋巴细胞亚群含量。结果发现：10周体育舞蹈训练后，实验组男女血清免疫球蛋白IgG均极显著性升高(P<0.01)，T淋巴细胞亚群CD4+%及CD4+/CD8+比值出现极显著性和显著性升高(P<0.01，P<0.05)，血清IgM有升高趋势，IgA、CD8+%趋于下降，但均无显著性变化。结果说明：长期体育舞蹈锻炼可提高机体免疫功能。 |

The said findings indicated that long-term sports dance exercising can enhance body immunity functions. |
