Abstract
Background: Vasoactive intestinal peptide (VIP) plays an important role in modulating coronary blood flow and heart rate. The purpose of the present study was to investigate the effect of eight weeks of low intensity aerobic exercise on plasma levels of VIP hormone, blood pressure and heart rate in healthy elderly men and women, and patients with coronary artery disease (CAD).
Methods: In this study, 15 healthy women and 15 healthy men and 15 female and 15 male with CAD disease were randomly chosen as the experimental and control groups. Subjects did aerobic exercises tree days/week, for eight weeks, with the heart rate of 10010 beats per minute. Blood samples were taken from each subject in three stages, (before, immediately after and 24 hours after the 8 weeks of exercising).
Results: The results showed that there was a significant difference among plasma VIP levels in the four groups. Moreover, a significant difference was observed between the systolic blood pressure in the four groups (P=0.01) and the systolic blood pressure in male patients and healthy women (P=0.03) while there was no meaningful difference the systolic blood pressure in the two other groups. There was also a significant difference in the heart rate of the three rounds of sampling in the three of groups (P=0.002) but no significant difference was observed in healthy men.
Conclusion: According to the above results, it seems that the duration and intensity of each workout should be considered to reach the VIP stimulation threshold. It may bring about considerable changes in VIP levels.

Abstract
Background: 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 & TNF-α response to an interval acute training. Therefore, we investigated the effects of acute interval exercise on plasma visfatin, TNF-α and IL-6 levels, in healthy female rats. Furthermore, correlate between changes probably these factors were also assessed.
Methods: 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-α and Visfatin levels were measured by ELISA analysis. Data were analyzed using analysis of variance with measures (ANOVA) and post hoc Tukey test.
Results: Acute interval treadmill exercise led to significant decreases in visfatin (P= 0/036), IL-6 (P= 0/009) and TNF-α (P= 0/022) plasma levels between the groups. Also, this study no significant correlations between the changes in adipokines were observed.
Conclusion: Decreased levels of TNF-α 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.
