Beta-Alanine Repeated Sprint Performance Randomized TrialImportantly, mechanistic evidence indicates that performance loss during repeated maximal efforts reflects an integrated disturbance in muscle function—encompassing substrate availability, metabolite/ionic perturbations, excitation–contraction coupling, and only later, more pronounced acid–base disruption—rather than a single dominant metabolite (–).1Liang Weibao (2026)No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials
Beta-Alanine Repeated Sprint Performance Randomized TrialConsistent with this mechanism, contemporary meta-analytic evidence indicates the most reproducible ergogenic effects in high-intensity exercise tasks of approximately 1–4 min, where acid–base perturbation is more likely to be performance-limiting ().1Liang Weibao (2026)No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials
Beta-Alanine Repeated Sprint Performance Randomized TrialBiopsy-based repeated-sprint experiments show that recovery of subsequent sprint performance is tightly associated with PCr resynthesis even when muscle pH remains depressed, suggesting that acid–base normalization is not a prerequisite for short-term restoration of repeated-sprint capacity (,).1Liang Weibao (2026)No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials
Beta-Alanine Repeated Sprint Performance Randomized Trial1 2 3 4 5 7 Repeated sprint ability (RSA) is a defining performance attribute in intermittent sports, characterized by repeated maximal or near-maximal efforts separated by brief recovery, with an ensuing decline in mechanical output across bouts (,).1Liang Weibao (2026)No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials

Beta-Alanine Repeated Sprint Performance Randomized TrialBeta-alanine, caffeine or carbohydrate mouth rinsing are examples of evidence-based ergogenic aids.4Strasser B (2026)Dietary interventions interact with the perception of effort and enhance endurance performance: a brief narrative review.
Beta-Alanine Repeated Sprint Performance Randomized TrialConclusion While current evidence supports a key role for dietary interventions on endurance performance by influencing individuals' perceived effort, more research is needed to determine the optimal doses and precise formulations for different sports, in order to employ a personalized strategy.4Strasser B (2026)Dietary interventions interact with the perception of effort and enhance endurance performance: a brief narrative review.
