Weight Gain :: Physical Activity Plays Role in Weight Gain in Adolescent Girls
Girls who were inactive during adolescence gained an average of 10 to 15 pounds more than active girls, according to results of a 10-year observational study of obesity. Total calorie intake increased only slightly and was not associated with the weight gains. These new results show that a previously reported steep decline in physical activity among adolescent girls is directly associated with increased fatness and an increase of body mass index (BMI), a measure of body weight adjusted for height.
