Abstract: Regular and continuous physical activity has been reported to effectively prevent or delay the onset of type 2 diabetes, as well as increase insulin sensitivity and improve energy metabolic with metabolism, blood lipids, leptin, ghrelin, and homeostasis model assessment-estimated insulin resistance (HOMA-IR) factors. The objective of this study was to analyze the effects of aerobic exercise on leptin, ghrelin, blood lipids, and HOMA-IR factors in obese postmenopausal Korean women. Thirty-six healthy postmenopausal women (mean age, 54.47 ± 2.50 years) with >32 % body fat were randomly assigned to an aerobic exercise group (n = 18) or to a "no exercise" control group (n = 18). The subjects' body composition, blood lipid, HOMA-IR, leptin, and ghrelin levels were measured before and after the 16-week line dancing program. The exercise group exhibited a significant decrease in body weight, percent body fat, body mass index, visceral fat area, leptin, insulin, glucose, HOMA-IR, total cholesterol, triglycerides, apolipoprotein B, low-density lipoprotein cholesterol, and systolic and diastolic blood pressure. In addition, this group exhibited a significant increase in apolipoprotein A-I, ghrelin, and high-density lipoprotein cholesterol. Regular and continuous aerobic exercise (e.g., line dancing) effectively improved body composition, visceral fat, serum lipids, leptin, ghrelin, and HOMA-IR factors in obese postmenopausal Korean women.
