Quick Answer
Beta-Alanine Sprint Performance Meta-Analysis has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Methodological quality was assessed using the Cochrane RoB 2.0 tool, and the certainty of evidence was evaluated via the GRADE framework.
Key Takeaways
- 01Methodological quality was assessed using the Cochrane RoB 2.0 tool, and the certainty of evidence was evaluated via the GRADE framework. [Liang W (2026)]
- 02Conclusion In conclusion, chronic β-alanine supplementation does not provide a clear improvement in total work capacity, maximal anaerobic power, or fatigue resistance during repeated sprinting. [Liang W (2026)]
- 03Objective Chronic beta-alanine supplementation is a prevalent nutritional strategy to augment intracellular buffering capacity via elevated muscle carnosine. [Liang W (2026)]
- 04While its ergogenic efficacy in continuous, high-intensity exercise is established, its impact on repeated sprint ability (RSA)-governed by extremely brief work bouts and phosphocreatine (PCr) kinetics-remains equivocal. [Liang W (2026)]
The current Migaku evidence database contains 2 reusable source documents for Beta-Alanine Sprint Performance Meta-Analysis. This answer focuses on safety, limits, and clinician-discussion contexts.
- Methodological quality was assessed using the Cochrane RoB 2.0 tool, and the certainty of evidence was evaluated via the GRADE framework. [Liang W (2026); evidence level 1]
- Conclusion In conclusion, chronic β-alanine supplementation does not provide a clear improvement in total work capacity, maximal anaerobic power, or fatigue resistance during repeated sprinting. [Liang W (2026); evidence level 1]
- Objective Chronic beta-alanine supplementation is a prevalent nutritional strategy to augment intracellular buffering capacity via elevated muscle carnosine. [Liang W (2026); evidence level 1]
- While its ergogenic efficacy in continuous, high-intensity exercise is established, its impact on repeated sprint ability (RSA)-governed by extremely brief work bouts and phosphocreatine (PCr) kinetics-remains equivocal. [Liang W (2026); evidence level 1]
- Endurance performance improved only with protein (0.99; 0.16-1.83; 94.3%; very low). [Deng B (2025); evidence level 1]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
