Studies show 97 percent of American adults get less than 30 minutes of exercise a day, which is the minimum recommended amount based on federal guidelines. New research from the University of Missouri suggests certain genetic traits may predispose people to being more or less motivated to exercise and remain active. Frank Booth, a professor in the MU College of Veterinary Medicine, along with his post-doctoral fellow Michael Roberts, were able to selectively breed rats that exhibited traits of either extreme activity or extreme laziness. They say these rats indicate that genetics could play a role in exercise motivation, even in humans.
