Monitoring on mucosal immunity in national athletes of free-style sky ski before winter Olympic Games

目的:通过监测5周自由式滑雪空中技巧国家队运动员粘膜免疫指标变化,研究运动训练对唾液sIgA的影响,从而探讨运动、sIgA与上呼吸道感染间的关系。方法:以自由式滑雪空中技巧国家队10名运动员为研究对象,其中男选手5名,女选手5名。唾液的采集日期为训练开始后的连续14个训练日、第21天(第三周)、第28天(第四周)、第33天(第五周)。结果:运动员粘膜免疫指标sIgA和溶菌酶浓度在训练期间均无显著变化(P〉0.05)。
