the purpose of this study was to compare
acute and continuous effects of caffeine consumption
with a four-week anaerobic training on anaerobic
performance, serum lactate levels and body composition
values in active men. The study design was a quasi-
experimental one. Experimental and control groups
were compared in the phases of pre-test and two post-
tests. Thirty-two active male students performed a
400m-run and blood samples were collected 2 minutes
later. Next day, Wingate test was conducted to assess
anaerobic power. Then, all subjects were randomly
divided into 2 groups: caffeine consumption
(Experimental group) and placebo (Control group),
performing a 4-week anaerobic exercise. Finally, blood
samples have been collected like before; then, each
group was divided into 2 subgroups (caffeine or placebo
consumption for one day) and blood samples have been
collected after a 400m-run again. Subjects also
consumed either caffeine or placebo at a dose of 5
mg/kg of body weight. T-tests were used to analyze
data, at a significance level of P<0.05. Four weeks
Anaerobic training with and without caffeine
consumption decreased the time of 400m-run and
elevated serum lactate levels (p=0.001) (higher
differences were observed in caffeine group), but had no
significant effect on Wingate test results. Weight value
only increased in Experimental group. Acute
consumption of caffeine in placebo group also decreased
the time of 400m-run and elevated lactate levels
(p=0.001). Acute and continuous consumption of
caffeine along with anaerobic exercise improved
anaerobic performance; while increased serum lactate
levels in active men.
