[ effect of eight week interval acute training on plasma visfatin, TNF-alpha and IL-6 in rats: a brief report]

ABSTRACT

Adipokines are peptides secreted by adipose tissue that affect whole-body energy metabolism. Exercise training exerts beneficial effects on adipose tissue. However, less is known regarding visfatin's, IL-6 and TNF-alpha response to an interval acute training. Therefore, we investigated the effects of acute interval exercise on plasma visfatin, TNF-alpha and IL-6 levels, in healthy female rats. Furthermore, correlate between changes probably these factors were also assessed. This study was conducted experimentally. Forty five female sprague dawley rat were randomly divided into three groups pre test [n = 15], treadmill exercise [n = 15] and sedentary controls [n = 15]. The acute alternative exercise consisted of treadmill running 3 session/ week for 8 week. The changes of plasma IL-6, TNF-alpha and Visfatin levels were measured by ELISA analysis. Data were analyzed using analysis of variance with measures [ANOVA] and post hoc Tukey test. Acute interval treadmill exercise led to significant decreases in visfatin [P = 0/036], IL-6 [P = 0/009] and TNF-alpha [P = 0/022] plasma levels between the groups. Also, this study no significant correlations between the changes in adipokines were observed. Decreased levels of TNF-alpha and IL-6 correlated with intensity and duration exercise. Furthermore, probably there were some factors except weight decreasing that affects on visfatin decrease. Therefore, the reduction of this factor may cause in preventing metabolic disease
