中文摘要:

为了了解我国优秀速滑运动员赛前阶段的机体免疫情况。对齐齐哈尔市冬季运动项目管理中心速滑队的8名女子1500 m项目运动员赛前训练阶段的IgG、IgM、IgA及IL-2、IL-6的水平进行测定。结果显示，IgM在赛前第二周下降可能与IL-2的降低、皮质醇的升高有关。sIL-2R浓度的升高中和活化了的T淋巴细胞周围的IL-2，降低IL-2介导的免疫反应，使T淋巴细胞逐渐静息，导致机体免疫功能受到抑制。处于应激状态的特定环境之中，以及免疫功能失调均可使IL-6的分泌水平升高；从肌源性IL-6的角度分析，IL-6的逐渐升高也可能与速滑运动员的运动负荷增加和滑行的肌肉收缩方式有关。皮质醇含量逐渐上升，可能与调控IL-2降低其水平有关。

英文摘要:

In order to find out the immune conditions of China's elite speed skating athletes during the pre-competition period, a test was made on the level of IgG, IgM, IgA, IL-2 and IL-6 of the eight female 1500m speed skaters. The result shows that IgM decrease in S2 may be related to IL-2 decrease and increase of cortex. The increase of sIL-2R concentration neutralizes and activates IL-2 around T lymphocytes and lowers immune response introduced by IL-2. This leads to the gradual tranquility of T lymphocytes and results in inhibition of immune function. Special environment of stress and immune disorders may result in the increase of IL-6 secretion. From the angle of muscle-derived IL-6, gradual increase of IL-6 may relates to the increase of the training load and the method of muscle contraction. The gradual increase of cortex level may relates to the control and reduction of IL-2.
