Men and women who were fit, as judged by a treadmill test, but were overweight or obese had a lower mortality risk than those of normal weight, but low fitness levels, the study in the Journal of the American Medical Association showed.
Exercise expert Steven Blair of the University of South Carolina and colleagues tracked the death rates of about 2,600 people age 60 and up, examining how physical fitness and body fat affected their death rates over 12 years.
Those in the lowest fifth in terms of fitness had a death rate four times higher than participants ranked in the top fifth for fitness.
"Being fit provides protection against mortality in these men and women . . ., whether they're normal weight, overweight or obese," Blair said.
