WINSTON-SALEM, N.C., March 28 (UPI) -- U.S. researchers say an early indication of when otherwise healthy older adults are about to lose some of their ability to get around is a change in thigh fat.
Kristen Beavers of Wake Forest Baptist Medical Center looked at data on how changes in muscle and fat in the thighs affected the walking speed of about 2,300 people in their 70s.
