Therefore, this study aimed to systematically review the evidence regarding the effects of beta-alanine on exercise capacity, muscle strength, and functional performance of older adults. <jats:bold><jats:italic>Methods:<\/jats:italic><\/jats:bold>\u00a0This systematic review was conducted following the specific methodological guidelines of the Preferred Report Items for Systematic Reviews and Meta-Analyses and the Physiotherapy Evidence Database scale. Furthermore, the Cochrane risk-of-bias assessment tool was used. The search was carried out in five relevant databases (MEDLINE, Embase, Web of Science, Scopus, and Cochrane Library) from inception up to March 2024. <jats:bold><jats:italic>Results:<\/jats:italic><\/jats:bold>\u00a0Of the 1,749 registers identified, only five met the established criteria and were included in this systematic review.
