众多流行病学研究显示,适量运动提高机体抗病能力,过度训练则使机体对各种疾病尤其是细菌和病毒感染性疾病的易感性增加。对运动中体液免疫状况的研究显示,唾液免疫球蛋白A(Salivaryimmuno-globulinA,sIgA)水平是人体黏膜免疫状况的一个重要指标,急性大强度运动或长时间大强度
Many epidemiological studies have shown that moderate exercise improves the body’s resistance to disease and over-training increases the body’s susceptibility to various diseases, especially bacterial and viral infectious diseases. The study of humoral immune status in exercise shows that Salivaryimmuno-globulin A (sIgA) level is an important indicator of human mucosal immune status. Acute high-intensity exercise or long-term high-intensity
