What the publication reports
Twelve reports from 11 randomized trials included 312 women. Time to exhaustion favoured beta-alanine across eight studies and 187 participants, while pooled estimates for peak power, anaerobic performance, oxygen uptake and body fat were imprecise or neutral.
Limits and interpretation
Certainty was rated very low for every outcome because of bias, imprecision, publication bias and, for some outcomes, indirectness. The time-to-exhaustion signal should not be generalized to all performance tasks.
