Abstract
Purpose
To investigate the effects of the combination of amino acid supplement and resistance training on body composition and muscular fitness in healthy people.
Methods
Participants in this study were those who were 30 healthy males and females aged between 25-50 years old. They were randomly divided into control group (CON) received resistance training only and experimental group (AA+RT) received essential amino acid powder and resistance training for a total 12 weeks. Body composition, muscle strength, and muscle size were carefully monitored before, at 6 weeks, and 12 weeks of the program. Then, SPSS software was utilized to perform the statistical analysis with Mixed-model ANOVA with LSD post hoc test. The p value less than 0.05 was set as the statistical significance.
Results
After 12 weeks, AA+RT showed the decreased body fat mass (p<0.05) when compared with before training. While there were no significant differences on control group (p>0.05). Moreover, arms and legs muscle strength, circumference, and thickness were significantly increased at week 6 and the end of 12 weeks in both groups with no significant differences among groups (p>0.05).
Conclusion
The combination of amino acid supplement and resistance training can improve body composition greater than resistance training alone while muscular strength and size were similar.
