| description | Ergogenic effects of caffeine
on anaerobic maximal and submaximal peak performance, especially in resistance
exercise is not clear. According to this, the purpose of this study was to
investigate the acute effect of moderate amounts of caffeine on maximal
strength, repetition sustainability and work volume in the upper and lower body
of novice body builders. In a randomized double blind study, 15 male
body builders' athletes (age of 21.16±3.9 years, height of 174.42±6.12 cm and
weight of 73.25±6.71 kg) were examined. Exercise protocol was to test one
repetition maximum (1RM) in the bench press and leg press and repetition
sustainability of bench press and leg press with 80% 1RM in 5 sets. These tests
were performed, one hour after ingesting caffeine (6 mg/kg) and placebo, in two
separate sessions as similar. Muscle strength, sustainability of repetitions
and volume of work (load × the number of repetitions) of upper and lower body
were measured. To examine the differences between the effects of caffeine and
placebo, t-test was used. The results showed that caffeine causes a
significant increase in the strength of the upper and lower body (P<0.05).
The repetition sustainability of upper and lower body in the first, second and
third sets did not change significantly, but decreased significantly in the
fourth and fifth sets. In addition, volume of work at the first to fifth set
with consumption of caffeine in the body was significantly more than placebo
(P<0.05). However, in the first and second set of lower body exercise was
not observed significantly difference and meaningful difference was only seen
in the third to fifth set between caffeine and placebo conditions (P<0.05).
It seems that acute consumption of caffeine supplementation with ergogenic
effect on maximal strength, sustainability of repetitions and the training
volume in resistance exercise improve performance and possibly stimulate muscle
for its development. |
