Sports medicine in the management of obesity and related disorders

• Park HK

Abstract

In 2009, obesity affected 32% of the adult population of Korea. Obesity is associated with a variety of chronic diseases. Weight reduction reduces health risks associated with chronic diseases and is therefore encouraged by the Korean health plan 2020. Aerobic activities should be performed in periods of at least 10 minutes and, ideally, should be performed five or more days a week. Evidence supports moderate-intensity physical activity (PA) for 150 and 250 min/wk to be effective in preventing weight gain. Moderate-intensity PA between 150 and 250 min/wk will provide only modest weight loss. Greater amounts of PA (>250 min/wk) have been associated with clinically significant weight loss and weight maintenance after weight loss. Moderate-intensity PA between 150 and 250 min/wk will improve weight loss in studies that use moderate diet restriction, but not severe diet restriction. Resistance training does not enhance weight loss, but may increase fat-free mass and increase loss of fat mass, and is associated with reductions in health risk. Existing evidence indicates that endurance PA or resistance training without weight loss reduces health risk. All adults including obese people should also perform muscle-strengthening activities two or more days a week. Experts in sports medicine should participate in creating the Korean guidelines for physical activity and clinical services for patients with obesity.
