These new pediatric diseases include type-2 diabetes, metabolic syndrome, and non-alcoholic fatty liver disease, a condition in which fat builds up in the liver, potentially impairing its function over time. These include reducing total fat, fat packed around organs in the abdomen (known as visceral fat, a risk factor for diabetes), and liver fat, and improving fitness of their heart and lungs. To see if physical activity might work in the same way for obese adolescent girls, Lee and her colleagues performed a new study that compared the health effects of two different types of exercise — aerobic exercise and weight lifting — over three months to remaining sedentary. Although their results show beneficial effects for both types of exercise, the researchers found that girls who performed aerobic exercise, but not weight lifting, had significant reductions in visceral fat and liver fat, as well as improvements in insulin sensitivity, another risk factor for diabetes that’s linked with obesity. The article is entitled “Aerobic Exercise But Not Resistance Exercise Reduces Intrahepatic Lipid Content and Visceral Fat and Improves Insulin Sensitivity in Obese Adolescent Girls.” It appears in the online edition of the American Journal of Physiology-Endocrinology and Metabolism, published by the American Physiological Society.

Exercise More Fun When Friends Join You, New Research Shows
Eight times a day, participants received a prompt on their phone that asked them what they were doing, who they were with, where they were, and if they were outdoors, how much “greenness” was in the area. They also rated how happy they were , and how much they were enjoying the activity they were doing. About 84 people reported at least one bout of physical activity over the four days. [ 10 Fitness Apps: Which Is Best for Your Personality? ] Those doing physical activity were happier, and enjoyed the physical activity more, when they were with their spouse, friends or co-workers, compared with when they were alone, according to the findings.
