This research delves into the multifaceted realm of Branched-Chain Amino Acids (BCAAs) as potential ergogenic aids, specifically exploring their impact on exercise-induced muscle damage. The investigation spans an extensive literature review of studies conducted in the United States from 2010 to 2023, synthesizing diverse methodologies and outcomes. The study employs a systematic approach, considering randomized controlled trials, observational studies, and intervention studies to provide a comprehensive understanding of the nuanced relationship between BCAAs and exercise-induced muscle damage. Findings reveal varied outcomes, suggesting BCAAs may influence markers such as Creatine Kinase levels, recovery time, and muscle soreness. However, inconsistencies and individual variations underscore the complexity of this interaction. The paper also elucidates the biochemical mechanisms through which BCAAs act, addressing considerations for optimal dosage, timing, and potential side effects. Practical implications are drawn for athletes and fitness enthusiasts, emphasizing personalized approaches within the broader context of sports nutrition. Acknowledging limitations, the study concludes with a call for continued research, refining methodologies and advancing the understanding of BCAAs in optimizing athletic performance and recovery.
