|---|---|---|---|---|
| Beta-Alanine Sprint Performance Meta-Analysis | Methodological quality was assessed using the Cochrane RoB 2.0 tool, and the certainty of evidence was evaluated via the GRADE framework. | 1 | Liang W (2026) | No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials. |
| Beta-Alanine Sprint Performance Meta-Analysis | 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. | 1 | Liang W (2026) | No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials. |
| Beta-Alanine Sprint Performance Meta-Analysis | Objective Chronic beta-alanine supplementation is a prevalent nutritional strategy to augment intracellular buffering capacity via elevated muscle carnosine. | 1 | Liang W (2026) | No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials. |
| Beta-Alanine Sprint Performance Meta-Analysis | 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. | 1 | Liang W (2026) | No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials. |
| Beta-Alanine Sprint Performance Meta-Analysis | Endurance performance improved only with protein (0.99; 0.16-1.83; 94.3%; very low). | 1 | Deng B (2025) | Dietary Supplement Strategies During Conditioning Training in Athletes: A Network Meta-Analysis of Peak and Mean Anaerobic Power, VO<sub>2</sub>max, and Endurance Performance. |
| Beta-Alanine Sprint Performance Meta-Analysis | Dietary supplements are often used during training to support energy provision, recovery, and adaptation, yet effects on peak and mean anaerobic power, VO 2 max, and endurance performance remain inconsistent. | 1 | Deng B (2025) | Dietary Supplement Strategies During Conditioning Training in Athletes: A Network Meta-Analysis of Peak and Mean Anaerobic Power, VO<sub>2</sub>max, and Endurance Performance. |
| Beta-Alanine Sprint Performance Meta-Analysis | Unlike prior syntheses centred on neuromuscular outcomes (strength and hypertrophy), this study compared six common supplements-protein, creatine, β-alanine, HMB, vitamin D, and nitrate-on energy-system performance (peak anaerobic power, mean anaerobic power, VO 2 max, and endurance performance) using network meta-analysis. | 1 | Deng B (2025) | Dietary Supplement Strategies During Conditioning Training in Athletes: A Network Meta-Analysis of Peak and Mean Anaerobic Power, VO<sub>2</sub>max, and Endurance Performance. |
