How exercise in old age prevents the immune system from declining - BBC News

They followed 125 long-distance cyclists, some now in their 80s, and found they had the immune systems of 20-year-olds.

Prof Janet Lord, director of the Institute of Inflammation and Ageing, at the University of Birmingham, and co-author of the research, 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.

"Because the cyclists have the immune system of a 20-year-old rather than a 70- or 80-year-old, it means they have added protection against all these issues."

The researchers looked at markers in the blood for T-cells, which help the immune system respond to new infections.

These are produced in the thymus, a gland in the chest, which normally shrinks in size in adulthood.

They found that the endurance cyclists were producing the same level of T-cells as adults in their 20s, whereas a group of inactive older adults were producing very few.
