The effect of 7-day BCAAs consumption on delayed onset muscle soreness indices of beginner futsal players

Nowadays, usage of protein and amino acid supplements is focused for decreasing muscular injuries after intensive exercise sessions. The aim of the present research was to indicate the effect of 7-day branched-chain amino acids (BCAAs) consumption on the delayed onset muscle soreness (DOMS) in beginner futsal players.
In this semi-experimental double blind study, the population included the beginner futsal players of Tehran’s Enghelab Sports Complex. 20 volunteers (with an average age of 28.67±4.72, average weight of 90.17±12.09 Kg) were randomly divided into 2 groups of supplement (n=10) and placebo (n=10). The participants consumed the supplement (S) or the placebo (P) 7 days before one session of weight exercises with 80% one repetition maximum (1RM) in 3 sets and each set with 8 repetitions. Repeated measurement ANOVA was used for data analysis.
The results showed that after 48 hours CK had a lower increase in S group compared to P group (from 238.83±86.33 to 417.17±184.77 IU/L in S group and 229.83±58.98 to 445.0±227.44 IU/L in P group), but there was no significant difference (P=0.767). On the other hand, LDH didnot show any difference in measurement phases between two groups (before 301.33±58.42 immediately after 333.33±56.43 and 48 hours after 337.33±47.82 IU/L in S group and before 297.83±43.28 immediately after 297.17±69.75 and 48 hours after 292.17±60.02 IU/L in P group) (P=0.280).
The results indicate that 7-day BCAAs consuming before vigorous resistance exercise did not have a significant effect on the DOMS indices in beginner futsal players.
