| description | The aim of current study was to
investigate the effect of four weeks of beta-alanine supplementation on
anaerobic power and plasma lactate level of unprofessional male bodybuilders.
For this purpose, the study plan was performed as pretest-posttest with control
group and as one blind trial. 20 mature and unprofessional athletes were
randomly divided into two groups of 10 people including supplement and placebo
(supplement group: 25±0.81 years old, weight 82.10kg±4.78 kg and BMI
24.34±2.19kg/m2 and placebo group: 24.40± 1.07 years old, weight
80.60±5.85 kg and BMI 23.34±1.16 kg/m2). Within experimental period
of four weeks, the subjects of supplement group received six mg daily
beta-alanine supplement for five days a weeks and the subjects of placebo group
received placebo to the same dosage (Aspartate Flavor Powder). Both groups also
participated in four weeks of bodybuilding exercises, designed by the researcher.
As pretest and posttest, the subjects of both groups participated in anaerobic
test of RAST respectively in one day before and after finishing experimental
period to evaluate the indicators of anaerobic power and to measure blood
lactate levels. Blood samples were taken from them immediately after RAST test.
To analyze data, dependent t-test as well as two-way covariance analysis test was
used. Statistical operations were checked in significance level of P≤0.05 and
then the following results were obtained: compared to placebo group, four weeks
of beta-alanine supplementation led to significant improvement of anaerobic
peak power and fatigue index of subjects (P≤0.05) but it didn’t have any
significant effect on average anaerobic power and plasma lactate level
following one session of intense anaerobic activity. Since, increased anaerobic
peak power and reduced fatigue can indicate improvement of subjects’ anaerobic
power, it can be concluded that this type of supplementation has caused
improvement of participants’ anaerobic power. |
