New study at University of Michigan on results of exercise on the molecular self

The Detroit News (1/27, Kozlowski, 473K) reports “a groundbreaking study is being launched this month” at 19 research centers across the US with the goal of determining how exercise changes the body at the molecular level. The six-year study funded by the National Institutes of Health, aims to “create a map of molecular changes that occur as a result of physical activity based on samples from 3,000 people of different races, ethnic groups, sex, ages and fitness levels.” NIH Director Francis Collins said in a video about the research, “We know that different parts of the body talk to each other during exercise, but we don’t know what their language is. We’re trying to figure out the voice that’s being used by these molecules in the space of an exercise program that actually improves other parts of the body’s function whether that’s muscle building, strength and bones or even mental status, and resistance to depression.”
