Introduction: Visfatin is predominantly secreted from visceral adipose tissue and mimics
the effect of insulin by binding to insulin receptors. The purpose of the present research is
to examine the effect of glucose intake on plasma visfatin concentration following an
aerobic exercise session.
Methods: In a quasi-experimental study, 16 male non-athlete students (21.91±2.31 yrs.,
77.53±8.93 kg, 1.768±0.07 cm, 24.31±2.07 kg/m2) were randomly divided into water
and glucose groups. Blood samples were collected at five stages: before exercise,
immediately after exercise, and 30, 60, and 90 minutes after exercise. The subjects were
instructed to perform a 45-minute aerobic exercise (a 10-min warm-up, followed by a 1-
mile running at maximum speed with 3-minute rests between bouts). Immediately after
the second blood sampling, sugary liquids (1.5g glucose for each kg body weight) and
water (similar volume) were administered. The data was analyzed using repeated
measures ANOVA and LSD test at P<0.05.
Results: Plasma visfatin levels increased immediately after exercise, but the increase was
not significant. At the following times (30, 60, and 90 minutes after exercise), plasma
visfatin levels decreased in both groups, but the decrease was not significant. Significant
difference was observed in the visfatin levels of the glucose group at 60 and 90 minutes
after exercise compared to immediately after exercise. The plasma glucose level of the
glucose group was significantly lower than the water group. Significant increase in plasma
insulin was observed by glucose intake at 30 and 60 minutes after exercise. Although at
90 minutes after exercise the plasma insulin level of the glucose group was higher than
that of the water group, but the difference was not significant.
Conclusion: According to the findings, changes made in visfatin levels following acute
exercise and glucose intake is not significant. So, probably visfatin has no role in
improving the acute exercise-induced metabolic status and glucose intake in healthy
