The Immune System Mediates Some of the Benefits of Exercise

It is uncontroversial to point out that exercise is good for long-term health. It slows aging, reduces risk of age-related disease, reduces mortality. A mountain of evidence supports these assertions, both animal studies demonstrating causation, and any number of large human studies showing correlation. Exercise, like the practice of calorie restriction, produces sweeping changes in the operation of metabolism. Near everything is different, both in the short term following exercise, and over the long term when looking at differences between the biochemistry of a fit individual versus that a sedentary individual. This can make it hard to determine which of the countless specific changes are important, or where they sit in the network of cause and effect. Cellular biochemistry remains incompletely understood and explored. There is plenty of room to take even a very well studied subject, such as the beneficial effects of exercise, and find something novel to say about it. In today's research materials, scientists discuss a recent discovery related to the role of the immune system in mediating some of the benefits to health that result from exercise, such as reductions in inflammatory signaling. Given the age-related decline of the immune system, and the chronic inflammation of aging, it is interesting to consider how this part of the response to exercise likely breaks down with age. Some benefits of exercise stem from the immune system Most previous resear...
