Beta Alanine Sprint Performance Randomized TrialMethodological quality was assessed using the Cochrane RoB 2.0 tool, and the certainty of evidence was evaluated via the GRADE framework.1Liang 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 TrialConclusion 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.1Liang 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 TrialObjective Chronic beta-alanine supplementation is a prevalent nutritional strategy to augment intracellular buffering capacity via elevated muscle carnosine.1Liang 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 TrialWhile 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.1Liang 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 TrialResults 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).2López-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 TrialConclusion 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 2024.2López-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 TrialIntroduction 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.2López-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 TrialMethods 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 -).2López-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.
