Metabolic disorders occurring in menopause, including dyslipidemia, disorders of carbohydrate metabolism, components of metabolic syndrome, constitute risk factors for cardiovascular disease in women. Irisin and fibroblast growth factor-21 (FGF-21), which regulate browning, and high molecular weight (HMW) adiponectin have emerged beneficial for metabolic health. The purpose of the study was to examine the effect of endurance aerobic exercise on circulating browning factor and HMW-adiponectin level in postmenopausal women. Twenty-five postmenopausal women were included in this study. The aerobic exercise program consisted of 60 min of walking exercise at 50%?60% maximum oxygen uptake, and conducted 3 times per week for 6 weeks. Body composition, blood pressure, lipid profiles, physical fitness, and concentration of plasma irisin, FGF-21, HMW-adiponectin were analyzed before and after exercise. Waist circumference, systolic blood pressure, and triglyceride levels decreased, and levels of high-density lipoprotein cholesterol, irisin increased after exercise. However, there were no significant changes in FGF-21 and HMW-adiponectin. Balance and flexibility among physical fitness indices improved after exercise. These results suggested that moderate intensity walking could be the ideal type of exercise in menopausal women to induce a positive change in metabolic health markers, including an increase in irisin levels. Further studies are needed to determine the effects of exercise on brown adipose tissue browning factor.
