Research Suggests Interference with Muscle Response to Resistance Exercise
BOSTON–As men and women age, increasing quantities of fat tissue inevitably take up residence in skeletal muscle. A small study of older and younger men conducted at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University suggests that a build-up of a fat molecule known as ceramide might play a leading role in muscle deterioration in older adults. The results of the study were published online this month by the Journal of Applied Physiology, a publication of the American Physiological Society.
