تاثیر دوازده هفته تمرین هوازی بر سطوح رسیستین سرم و شاخص‌های AR، HOMA-AD و IRAR در مردان چاق کم‌تحرک

Background: Resistin levels and insulin resistance increase in obese humans. Also, inactive life is associated with high risk of increased insulin resistance. The purpose of this study was to investigate effect of twelve weeks aerobic training on serum levels of resistin, and adiponectin-resistin (AR), homeostasis model assessment-adiponectin (HOMA-AD), and IRAR indices in sedentary obese men. Methods: In a semi-experimental study, twenty one sedentary obese men were randomly placed into two groups: aerobic training (n=10, 27.8±3.2 yr, 93.5±7.1 kg, 31.7±3.4 %, BMI 32.0±3.5 kg/m2) and control (n=11, 27.1±3.1 yr, 94.7±6.0 kg, 31.2±3.1 %, 32.2±3.3 kg/m2). General characteristics of subjects, serum levels of resistin, and HOMA-AD, AR, and IRAR indices were assessed before and after training. Aerobic training consisted of twelve weeks pedaling on cycle ergometer (3 sessions per week, intensity 60-70% of reserved heart rate, duration of each session 20-40 min). Data analyzed by SPSS16 software. Statistical significance was considered at P0.05). Conclusion: Circulating levels of resistin and HOMA-AD, AR, and IRAR, that are novel indices for insulin resistance, were reduced after twelve weeks aerobic training. Therefore, sedentary obese men can reduce risk of type 2 diabetes and cardiovascular diseases with performing aerobic training.
