| 摘 要： | 运动对机体免疫功能有急慢性以及正负性影响。有规律的适度运动可增强免疫功能而降低感染风险。急性运动后肌源性IL-6释放增加，IL-10上升从而抑制细胞免疫功能。急性运动增强自然杀伤细胞活性但是降低白细胞的吞噬功能。长时间的高强度运动可能会通过抑制黏膜IgA分泌而增加上呼吸道感染风险。定期补充抗氧化剂如维生素C和E以及在运动过程中摄入碳水化合物有助于预防免疫抑制。平衡营养饮食匹配合理的运动计划可支持和促进免疫系统。

| Abstract: | Exercise has acute and chronic influences on immune function. Regular moderate exercise may benefit immunity and is associated with a reduced risk of infection while prolonged strenuous exercise may cause a temporary immune suppression that usually lasts about 3 - 24h after exercise, depending on the intensity and duration of the exercise. Acute exercise bout may up - regulate the release of IL - 6 from muscle, leading to an increase in IL - 10 and inhibition of cellular immunity. Acute exercise temporarily enhances natural killer cell activity but inhibits leukocyte phagocytosis. Prolonged strenuous exercise may inhibit mucosal immunity by decreasing IgA secretion, leading to a possible increase risk of upper respiratory infection. Balanced nutrition including long - term antioxidant （e. g. Vitamin C and E） supplementation and carbohydrate intake during exercise has been shown to be beneficial to immune function and to prevent immune suppression induced by heavy exertion. Well -balanced nutrition accompanied to well -designed exercise schedule is recommended to athletes. |
