ABSTRACT |
The purpose of this study was to investigate the effects of 12-weeks walking exercise on appetite regulating hormone, adipokine and insulin resistance in postmenopausal obesity women. The 15 postmenopausal obesity women (%fat; 30.8±1.6%, BMI; 26.3±0.8) were volunteered for this study, and experimental exercise protocol was treadmill walking (5 km/day, 6 day/week, 12 weeks). Blood sample were drawn before and after 12 weeks exercise, and blood lipids, plasma glucose, insulin, leptin, ghrelin, HOMA-IR, TNF-α were measured. The maximal oxygen consumption was significantly increased after training (p<.05), and the %fat was significantly reduced after 12-weeks walking (p<.05). Plasma glucose, insulin levels and HOMA-IR were significantly reduced after 12-weeks 5 km walking (p<.05). Plasma leptin was significantly reduced after training (p<.05), and the plasma ghrelin levels was significantly increased after 12 weeks walking exercise (p<.05). TNF-α levels were not significantly changed after 12-weeks exercise. The results of this study indicate that 5 km walking exercise for 12 weeks significantly reduced %fat and attenuated insulin resistance. In addition, 5 km walking exercise of postmenopausal obesity women improved plasma leptin and ghrelin. |
