( Although a number of studies have sugge...)Exercise Reduces Inflammation,Health

Although a number of studies have suggested that regular exercise reduces inflammation a condition that is predictive of cardiovascular and other diseases, such as diabetes its still not clear whether there is a definitive link. And if such a link exists, the nature of the relationship is by no means fully understood.

A recent study by kinesiology and community health researchers at the University of Illinois provides new evidence that may help explain some of the underlying biological mechanisms that take place as the result of regular exercise. According to the researchers, that knowledge could potentially lead to a better understanding of the relationship between exercise and inflammation.

The objective of their research was to examine the independent effect of parasympathetic tone in this case, determined by assessing heart-rate recovery after exercise on circulating levels of C-reactive protein (CRP). Parasympathetic tone and its inverse function sympathetic tone are components of the autonomic nervous system. CRP, which is secreted by the liver, circulates in the bloodstream and is a biomarker for inflammation in the body.

The sympathetic nervous system speeds things up, and the parasympathetic slows things down, said Victoria J. Vieira, a predoctoral fellow in kinesiology and community health and in nutritional sciences, and the primary author and designer of the study, published in a recent issue of the Journal of the American Geriatrics Society. So when youre exercising, your sympathetic nervous system will be on, increasing your heart rate, your respiration, etc. Once you stop, your body always tries to get back to homeostasis. So the parasympathetic nervous system kicks in to get everything back down to baseline levels.

Co-author and kinesiology and community health professor Jeffrey A. Woods said cardiologists are already routinely gauging CRP levels in much the same way they look at lipids p
