锻炼与免疫的关系

The Relationship between Exercise and Immunity

锻炼对机体免疫系统有影响,进而影响对疾病的易患性或疾病的结局。经常从事中等强度的锻炼与上呼吸道感染(URTI)存在负相关,而长期高强度的锻炼与URTI存在正相关;锻炼可改变宿主的固有免疫和适应性免疫功能,进而导致疾病易患性和严重程度的下降;锻炼通过各种机制发挥抗炎症作用,降低慢性炎症性疾病及其并发症的发生。

Numerous studies show that exercise affects the immune system, thereby affecting the outcome of the disease or susceptibility to disease. People often participating in moderate-intensity exercise and upper respiratory tract infection （URTI） are negatively correlated, while the long-term high-intensity is positively correlated with URTI exercise can alter the host innate immunity and adaptive immune function,leading to decreased disease susceptibility and severity;excereises can exert anti-inflammatory effects through a variety of mechanisms, which may reduce chronic inflammatory diseases and complications.
