Branched-Chain Amino Acid Plus Glucose Supplement Reduces Exercise-Induced Delayed Onset Muscle Soreness in College-Age Females

Figure 1

Delayed onset muscle soreness scores in subjects receiving a branched-chain amino acid supplement versus placebo. Effect of branched chain amino acid (BCAA) supplementation on delayed onset muscle soreness (DOMS) before (pre) and immediately following (post) squat exercise, measured in 24-hour intervals. Values are means ± SEM for all participants (𝑛=20). There was no significant difference between overall mean scores (area under the curve) for BCAA versus placebo (𝑃=0.106). No significant difference between BCAA and placebo (𝑃=0.142) 24 hours following squat exercise.
