The study design was conducted in two sessions with an interval of six weeks. Resistance protocol included 7 movements (2 lower body and 5 upper body movements) in 5 sets with 12 – 15 repeats and 50% of 1RM. In each session, randomly, half of the subjects received supplement (S) (4.5g BCAA solution) and the other half ingested placebo (P) (same amount of dextrose). Blood samples were collected before the exercise (fasting), immediately, 3 hours and 24 hours after the exercise. These results showed that BCAA supplement drastically increased the BCAA after the exercise (P %U https://jsb.ut.ac.ir/article_29777_39ffe8a892dffcf1ebdacd3d50853b7e.pdf
