[Purpose] The purpose of this study is to investigate the effects of circuit exercise on obesity index, appetite regulating hormones and insulin resistance in middle-aged obese women. [Subjects and Methods] The subjects of this study were 26 obese middle-aged women who were selected among participants in exercise class at K Region Health Promotion Center in South Korea and were randomly assigned to the exercise group (n=13; age 50.15 ± 3.82, % body fat 38.79 ± 3.28) and the control group (n=13; age 49.84 ± 2.96, % body fat 37.46 ± 2.51). Circuit exercise consisted of aerobic exercise and resistance exercise for 5 weeks and 50 minutes for 12 weeks. Before and after exercise we measured obesity index, leptin, ghrelin, fasting blood glucose, insulin, and insulin resistance in all subjects. A repeated-measured two-way of variance was performed for comparison of the treatment effects between the exercise and control groups. [Results] Body weight, BMI, and body fat percentage of obese index decreased significantly. Leptin of dietary regulation hormone was significantly decreased and ghrelin was significantly increased. Insulin and insulin resistance was significantly decreased. [Conclusion] Circuit exercise can be viewed as an effective exercise program to induce changes in appetite regulating hormones and to improve insulin resistance by mechanisms of energy homeostasis by weight loss.
[目的]本研究旨在探讨循环训练对中年肥胖女性肥胖指数、食欲调节激素及胰岛素抵抗的影响。[对象与方法]本研究的对象为26名肥胖中年女性，她们是从韩国K地区健康促进中心运动课程的参与者中选取的，并被随机分为运动组（n = 13；年龄50.15±3.82，体脂百分比38.79±3.28）和对照组（n = 13；年龄49.84±2.96，体脂百分比37.46±2.51）。循环训练包括有氧运动和抗阻运动，为期5周，共12周，每次50分钟。在运动前后，我们测量了所有受试者的肥胖指数、瘦素、胃饥饿素、空腹血糖、胰岛素和胰岛素抵抗。采用重复测量的双向方差分析来比较运动组和对照组之间的治疗效果。[结果]肥胖指数中的体重、BMI和体脂百分比显著下降。饮食调节激素瘦素显著降低，胃饥饿素显著升高。胰岛素和胰岛素抵抗显著降低。[结论]循环训练可被视为一种有效的运动方案，通过体重减轻实现能量稳态机制，从而引起食欲调节激素的变化并改善胰岛素抵抗。
