People know it’s important to avoid excessive weight gain as they get older, and that exercise is a key to success in this regard. But until recently, scientists had published surprisingly few studies purporting to quantify the impact of habitual exercise on weight gain over the long haul.
Dr. Arlene Hankinson and her colleagues at Northwestern University set out to do just that. Using data from a prospective follow-up study, Hankinson’s group showed that men who were able to maintain high activity levels over an extended period gained six fewer pounds, and five fewer centimeters of waist circumference than those in the lowest activity group. Women in the highest activity group gained 13 fewer pounds and nearly seven centimeters less around their waists.
To reach these conclusions, the scientists examined data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, which is a 20-year longitudinal study that began in 1985.
