topicBeta Alanine Reaction Time Randomized Trial
claimImportantly, 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 (–).

claimConsistent 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 ().

claimBiopsy-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 (,).

claim1 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 (,).
