A newly published study finds that exercising in older age can help keep one's immune system active and young. Researchers in Britain followed 125 cyclists over the age of 55 and found that they had immune systems of 20-year-olds. The researchers found these cyclists have higher levels of freshly made T-cells, which play an important role in one's immune response, such as recognizing and killing foreign invaders. Professor Janet Lord, director of the Institute of Inflammation and Ageing at the University of Birmingham, said "the immune system declines by about 2-3% a year from our 20s, which is why older people are more susceptible to infections, conditions like rheumatoid arthritis and, potentially, cancer."

一项新发布的研究发现,老年时期锻炼可有助于保持免疫系统活跃和年轻。英国的研究人员对125名55岁以上的自行车骑行者进行追踪,发现他们拥有20岁人的免疫系统。研究人员发现,这些自行车骑行者新产生的T细胞水平更高,T细胞在人体免疫反应中发挥着重要的作用,例如识别和杀死外来入侵物。伯明翰大学炎症与衰老研究所负责人珍妮特·洛德教授说:"从20多岁开始,我们的免疫系统每年会衰退约2-3%,这就是老年人更容易被感染,罹患类风湿性关节炎甚至癌症等疾病的原因。"
