Now for all you smokers out there here comes research that indicates that it isn't just your lungs and heart that ends up paying the cost of your smoking. It is also your muscles. These are the very things we need to build up to increase fat loss, increase balance, have stronger bones, and in general look better. Especially as we age. We definitley don't need to be losing any. The more muscle mass we have the higher our metabolism is as well.
This is definitely something to think about the next time you go to light one up.
Smoking may reduce muscle mass
NOTTINGHAM, England (UPI) -- University of Nottingham researchers say not only does smoking cause cancer, heart attacks and strokes, but smokers lose more muscle mass in old age.
Michael Rennie and Dr. Philip Atherton, with colleagues in Denmark and the United States, discovered that smoking impairs the day-to-day upkeep of muscle.
The findings, published in American Journal of Physiology and presented at Life Sciences 2007, show that smoking is likely to speed up a condition known as sarcopenia -- the loss of muscle mass with aging that is linked to poor balance, gait speed, falls and fractures.
"From our tests, we can conclude that smoking slows the muscle protein synthesis machinery -- probably impairing day-to-day upkeep of muscle," Atherton said in a statement.
"We are all well aware of the ill affects of smoking on the lungs, but our study reveals yet another cause of ill-health associated with smoking."
The researchers discovered that the amounts of myostatin, a muscle growth inhibitor, and MAFbx enzyme, which breaks down muscle protein, were higher in smokers than non-smokers.
