چکیده:
Introduction: This study compared the effects of 8–week of
concurrent exercises (aerobic and resistance training) with
and without Branch Chain Amino Acids (BCAA)
supplement on testosterone level and lipid profiles of male
body builders.
Material & Methods: Forty male body builders that had 3-4
years training background were randomly selected and
divided into two equal groups as control group who only did
concurrent exercises (aerobic–resistance) and experimental
group who perform concurrent exercise and taking BCAA
supplement after training and before going to bed. The
average age and body mass index of control group and experimental group were 24.8±5.1and 27.3±2.15, 25±2.1 and
27.4±2.13 respectively. To show the central tendency and
variability, descriptive statistics was applied. Independent ttest
analyses were carried out to discover the difference of
the two groups. Statistical significance was set at (P<0.05).
All data were analyzed by SPSS software, version 18.
Results: The results show significant decrease of Triglyceride
(TG) (P=0.001), low density lipoprotein (LDL-c) (P=0.034),
total cholesterol (TC) (P=0.003) and increase high density
lipoprotein (HDL-c) (P=0.001) in control group and decrease
of TG (P=0.001) LDL (P=0.037), TC (P=0.025) and
increases of HDL-c (P=0.002) in experimental group.
Furthermore, the testosterone level of subjects didn’t change
significantly in control and experimental groups.
Conclusions: In conclusion, concurrent training may be more
effective than endurance and strength training alone for
simultaneously improving the serum lipid profile.

Jafari and Ramezani (2012) studied the effects of 8-week concurrent training included (Interval endurance training and resistance training) and concurrent training (continuous endurance and strength training) on lipid profiles of obese non-active males.
Limitation of study about the influence of concurrent training and branched-chain amino acid supplementation on Lipid Profiles and Testosterone level and controversial in previous studies findings this study seems necessary.
Discussion This study was designed to investigate the effects of 8-week of concurrent training with and without BCAAs supplementation on lipid profiles and testosterone level in body builder male.
Swapnil et al studied the effects of 8 week resistance training on lipid profile and insulin levels in overweight/obese pre-pubertal boys and reported no significant changes in concentrations of TG, TC, HDL-c, and LDL-c (29).
