چکیده:

Introduction: The insulin resistance and subsequent pancreatic β cell failure that precedes the development of hyperglycemia is thus usually associated with obesity. Exercise training may improves these impairs, however, this is not well known. The aim of present study was to examine the effect of 8 weeks concurrent training on pancreatic β-cells function and insulin resistance in obese men. Material & Methods: Twenty three middle aged obese men (aged: 34.6 ± 8.8 years; ± SD) were randomly assigned to one of the concurrent training group (n=12) or control group (n=11). The concurrent group performed endurance and resistance training on the same days, 3 days a week for 8 weeks. The subjects in the control group were instructed to maintain their normal physical activity throughout the study. Results: The results indicated that fasting insulin (P=0.006), insulin resistance index (P=0.02), pancreatic β-cells function (P=0.04) decrease in the training group compare to the control group; however, fasting blood sugar has no significant change after the intervention (P=0.3). Conclusion: In summary, it seems that concurrent training utilized in this study improves insulin resistance and pancreatic β-cells function in obese men.

Effects of concurrent training on insulin resistance and pancreatic-cells function in obese men Ahmad Ahmadlu1*, Afsaneh Khazari2, and Zahra Momen Nasab2 Received: 23 November 2019 / Accepted: 12 January 2020 (1)* PhD in Exercise physiology, Education Administration in Shiraz, * PhD in Exercise physiology, Education Administration in Shiraz. Conclusion: In summary, it seems that concurrent training utilized in this study improves insulin resistance and pancreatic β-cells function in obese men . Keywords: Obesity, Concurrent training, Pancreatic β-cells function, Insulin resistance 1. Regular exercises improve those factors which relate to insulin resistance (9), and deter various complications such as cardiovascular disease (10); however, the data on the effects of exercise training on β-cell function are not well known. However, Omidi and Moghadasi (2017) showed that insulin resistance but not pancreatic β- cells function improved after 8 weeks of aerobic training in female patients with type 2 diabetes (12). The aim of present study was to examine the effect of 8 weeks concurrent training on pancreatic β-cells function and insulin resistance in obese men. The aim of present study was to examine the effect of 8 weeks concurrent training on pancreatic β-cells function and insulin resistance in obese men. The results of the current study in line with previous studies demonstrated that fasting insulin and insulin resistance determined by HOMA-IR and pancreatic β-cells function (HOMA-B) improve after 8 weeks concurrent training. Regular aerobic training improves insulin resistance but not pancreatic -cells function in female patients with type 2 diabetes.
