Prolonged intense exercise causes immunosuppression, whereas moderate-intensity exercise improves immune function and potentially reduces risk and severity of respiratory viral infections. Here, based on available evidence, we present a model whereby moderate exercise-induced increases in stress hormones reduce excessive local inflammation and skew the immune response away from a TH1 and toward a TH2 phenotype, thus improving outcomes after respiratory viral infections.
长时间剧烈运动可导致免疫抑制,而中等强度的运动可改善免疫功能,降低呼吸道病毒感染的风险和严重程度。在此,我们基于现有证据提出一个模型,即中等强度运动引起的应激激素增加可减少局部过度炎症,并使免疫反应从 TH1 向 TH2 表型倾斜,从而改善呼吸道病毒感染后的结果。
