Exercising can keep Your Immune System Healthy

Researchers in Britain followed 125 cyclists over the age of 55 and found that they had immune systems of 20-year-olds. This included 100 kilometers (62.1 miles) in under 6.5 hours for men and 60 km (37.3 miles) in under 5.5 hours for women.

The cyclists were healthier, both in terms of their muscles and their immune systems, than middle-aged couch potatoes.

The men's testosterone levels had also remained high, rather than declined with age, suggesting that they may have avoided most of the 'male menopause'.

Unlike a "control group" of adults who did not get regular exercise, the cyclists did not have loss of muscle mass or strength, did not have age-related increases in body fat or cholesterol levels, and their immune systems were as robust as much younger people.

T-cells are produced in the thymus, a gland in the chest, and it normally shrinks in size in adulthood - but the endurance cyclists didn't appear to suffer the results. Be that as it may, the thymuses of more seasoned cyclists were observed to create the same number of T-cells as those of youngsters.

"In any case, essentially, our discoveries expose the presumption that aging consequently makes us more delicate".

"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", study author and professor Janet Lord, the director of the Institute of Inflammation and Ageing at the University of Birmingham in the United Kingdom, told the BBC.

Professor Stephen Harridge, Director of the Centre of Human & Aerospace Physiological Sciences at King's College London, also added that, "The findings emphasise the fact that the cyclists do not exercise because they are healthy, but that they are healthy because they have been exercising for such a large proportion of their lives". The researchers measured markers of health, such as blood pressure, muscle mass, cholesterol and T cells, which are important in keeping our immune systems healthy.

"Their bodies have been allowed to age optimally, free from the problems usually caused by inactivity". "Our future studies in this cohort will aim to test immune function, notably the response to vaccination, as a clinical proof of the beneficial impact of physical activity on adaptive immune function in old age", they conclude.

The findings were published March 8 in the journal Aging Cell.

The researchers are planning to continue study the cyclists.
