摘要： 目的 观察不同强度的有氧运动对肥胖成年女性血清内脂素水平的影响。方法 选取120例肥胖成年女性，随机分为1个对照组和3个有氧运动组，每组30例。3个有氧运动组分别以大、中、小运动强度进行12周的有氧运动(每周3次，每次30min)，检测4组在试验前后血清内脂素水平的变化。结果 试验前，4组的基础代谢率(BMI)、胰岛素抵抗指数(HOMA-IR)和血清内脂素水平无明显差异。进行有氧运动锻炼12周后，3个有氧运动组的BMI、HOMA-IR和血清内脂素均明显下降，而中等强度有氧运动组的下降幅度最明显，与其他2组相比，差异有统计学意义。对照组的BMI、HOMA-IR和血清内脂素水平在试验前后无明显变化。结论 有氧运动，尤其是中等强度的有氧运动，可以显著降低肥胖成年女性血清内脂素水平。

Abstract: 【Abstract】Objective To determine the effect of different intensity of aerobic exercise on the level of serum visfatin in obese female adolescents. Methods 120 obese female adolescents were enrolled in this study and then were randomly divided into control group and three aerobic exercise groups (30 subjects in each group). Subjects in aerobic exercise groups were given a 12-week training program of high, moderate and low intensity of aerobic exercise respectively, which included three 30-minute sessions per week. The levels of serum visfatin of the four groups before and after experiment were examined. Results No significant differences in the level of body mass index (BMI), homeostasis model assessment-insulin resistance (HOMA-IR) and serum visfatin before experiment were found between the four groups. After 12 weeks of aerobic exercise-training, the levels of BMI, HOMA-IR and serum visfatin were significantly decreased in all aerobic exercise groups. In addition, moderate intensity of aerobic exercise group showed higher reduction of these parameters compared with the other two groups. However, there were no significant differences in the levels of these parameters in control group before and after experiment. Conclusions Aerobic exercise, especially moderate intensity of aerobic exercise, can result in reduced level of serum visfatin in obese female adolescents.
