【摘要】:目的:探讨高温高湿环境下大强度运动对人体血清白细胞介素12(interleukin-12,IL-12)的影响。方法:20名受试者随机分为运动组和暴露组,运动组在温度33℃、相对湿度分别为40%±2%(RH40%)和80%±2%(RH80%)的环境下进行递增负荷力竭跑台运动,两次不同湿度运动间隔1周。跑速从8 km/h开始,每分钟增加0.8 km/h,增加到16 km/h时不再增加,然后逐级递增坡度,以0.5%为起始坡度,实验过程中以受试者不能维持相应跑速,并自述不能坚持时终止运动。暴露组在高温中静坐,两者同时进出高温环境房。实验前和实验后即刻抽取静脉血。采用ELISA方法检测血清IL-12、皮质醇。结果:运动组RH40%和RH80%环境下运动后IL-12均显著性降低(P0.05);暴露组IL-12在RH40%暴露后出现降低趋势,RH80%暴露后显著性下降(P0.05)。运动组RH40%和RH80%环境下运动后血清皮质醇均显著升高(P0.01,P0.05);暴露组血清皮质醇RH40%暴露前后无显著性差异,RH80%暴露后显著性降低(P0.01)。结论:高温环境下,无论相对湿度高低,进行递增负荷大强度运动后血清IL-12均降低,可能由血清皮质醇显著升高对IL-12产生抑制作用所引起,但高温环境下运动引起免疫抑制的机制有待研究。
