| Beta Alanine Sprint Performance Randomized Trial | 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 Randomized Trial | 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 Randomized Trial | 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 Randomized Trial | 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 Randomized Trial | Results Salivary concentrations of NO 3 - and nitrite NO 2 - were also measured and in comparison to the placebo drink, the intake of beetroot juice increased salivary concentrations of NO 3 - (from 230 ± 435 vs 6164 ± 3370 μM; p = 2 - (130 ± 131 vs 4509 ± 4895 μM; p = 0.018; ES = 1.63). | 2 | López-Samanes Á (2026) | Acute beetroot juice ingestion fails to improve sprint performance and neuromuscular function in trained male sprinters: a randomized, double-blind, placebo-controlled study. |
| Beta Alanine Sprint Performance Randomized Trial | Conclusion Acute ingestion of 70 mL beetroot juice containing 6.4 mmol of NO 3 - did not enhance sprint performance or the neuromuscular function of male trained sprinters.Trial registration: The study was retrospectively registered in ClinicalTrials.gov with the following ID: 5-56NCT06675682 by 1 November 2024. | 2 | López-Samanes Á (2026) | Acute beetroot juice ingestion fails to improve sprint performance and neuromuscular function in trained male sprinters: a randomized, double-blind, placebo-controlled study. |
| Beta Alanine Sprint Performance Randomized Trial | Introduction The aim of this study was to evaluate the acute effect of beetroot juice ingestion on sprint performance and neuromuscular properties of male trained sprinters. | 2 | López-Samanes Á (2026) | Acute beetroot juice ingestion fails to improve sprint performance and neuromuscular function in trained male sprinters: a randomized, double-blind, placebo-controlled study. |
| Beta Alanine Sprint Performance Randomized Trial | Methods Twelve male sprinters (24.3 ± 4.8 years) participated in a randomized, double-blind, and placebo-controlled study with two experimental trials after the ingestion of 70 mL beetroot juice (containing 6.4 mmol NO 3 -) or 70 mL placebo drink (containing 0.04 mmol NO 3 -). | 2 | López-Samanes Á (2026) | Acute beetroot juice ingestion fails to improve sprint performance and neuromuscular function in trained male sprinters: a randomized, double-blind, placebo-controlled study. |
