Abstract

fetched live from OpenAlex

β-alanine is a popular supplement among athletes with 61% of competitive team sport players recently surveyed reporting β-alanine use.1 Despite its popularity, there is limited evidence on the most effective supplementation strategy and the systematic review and meta-analysis published by Sauders B et al 2 has shed some light on this issue. Athletes' understanding of β-alanine potential benefits and appropriate daily dose and duration of consumption is low,1 potentially compromising the impact of β-alanine supplementation in a real world setting. This editorial aims to highlight issues regarding the efficacy of β-alanine supplementation and suggest possible approaches to improve its effectiveness in the field. The mechanism of ergogenic effect of β-alanine as the precursor to carnosine synthesis is associated with an expansion of its key physiological role as a proton buffer with potential for antioxidant, glycation and calcium regulation influence.3 Increases in carnosine muscle levels depend on the β-alanine load provided.4 β-alanine supplementation of 4–6 g/day for …

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
