DOMIEH, A. M.; KHAJEHLANDI, A. Effect of 8 weeks endurance training on plasma visfatin in middle-aged
men Brazilian Journal of Biomotricity, v. 4, n. 3, p. 174-179, 2010. Visfatin, a novel adipokine, was increased
in 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 8 weeks
endurance training on plasma visfatin in middle-aged men. Nineteen healthy middle-aged men (aged 37.5 ±
4.8 years; height 173.7 ± 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=9) or control group (n=10). Endurance
training group underwent an 8-week intervention, with a frequency of 3 d/wk at an intensity corresponding to
65 – 80% maximum heart rate for 20 – 34 min. The 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. In
conclusion, it seems that 8 weeks endurance training induced change in adipose tissue, decrease plasma
visfatin in middle-aged men.
