Effect of 12 Weeks Endurance Training on Plasma Visfatin in Men مقاله

چکیده:

Objective: Visfatin, is a novel adipokine, and an adipose tissue-derived hormone shown to correlate with visceral fat mass in patients with obesity. It is not well known whether endurance training – induced change in adipose tissue and blood lipids decreases plasma visfatin or not; thus, the purpose of this study was to examine the effect of 12 weeks endurance training on plasma visfatin in men. Methods: twenty five healthy men (aged 37.5 ± 4.8 years; height 17˽.7 ± 6.5 cm; BMI 25.2 ± 2.6 kg/m2; mean ± SD) participated as subjects in this study. The subjects were randomly assigned to endurance training group (n=15) or control group (n=10). Endurance training group underwent an 12-week intervention, with a frequency of 3 d/wk at an intensity corresponding to 65 – 80% maximum heart rate for 20 – 34 min. Results: results showed that body fat percent, WHR and plasma visfatin were decreased (P<0.05) after endurance training. Maximum oxygen consumption, on the other hand, increases significant (P<0.05) in the training group compared with the control group. Plasma visfatin levels at baseline were positively correlated (P<0.05) with body fat percent and triglyceride concentration. Conclusion: In conclusion, it seems that 12 weeks endurance training induced change in adipose tissue, decrease plasma visfatin in men.

It is not wellknown whether endurance training – induced change in adipose tissue andblood lipids decreases plasma visfatin or not; thus, the purpose of this study was toexamine the effect of 12 weeks endurance training on plasma visfatin in men. Conclusion: In conclusion, it seems that 12 weeks endurance training induced change in adipose tissue, decrease plasma visfatin in men. It is not well known whether exercise–induced change in adipose tissue – decreases plasma visfatin; therefore, we examined the effects of 12 weeks endurance training on plasma visfatin in men. Researchers suggested that improving body composition and adipose tissue may effective mechanisms for decrease circulating levels of visfatin (Haus et al. The results showed that body fat percent and WHR decreased after endurance training, thus exercise- induced changes in body fat, especially visceral adipose tissue, may attribute to plasma visfatin decrease. On the other hand, there was the positive relationship between plasma visfatin and body fat percent at baseline and after the training. Therefore, additional researches are needed to determine the effects of exercise training on plasma visfatin, type 2 diabetes risk factors, inflammatory markers and their relationships. Conclusions In conclusion, endurance training induced change in adipose tissue, decrease plasma visfatin in men.
