Acute Effects of Beetroot Juice Supplements on Resistance Training: A Randomized Double-Blind Crossover. Nutrients. 2020 Jun 28;12(7):1912.http://hdl.handle.net/10668/15855The ingestion of beetroot juice (BJ) has been associated with improvements in physical performance in endurance sports, however the literature on resistance training (RT) is scarce. The aim of this study was to investigate the acute effects of BJ compared to a placebo (PLA) on muscular endurance and movement concentric velocity during RT. Twelve healthy men performed an incremental RT test (back squat and bench press) with three sets, at 60%, 70%, and 80% of their repetition maximum (1-RM). Movement velocity variables, total number of repetitions performed until concentric failure, blood lactate, and ratings of perceived effort post-training were measured. A higher number of repetitions were recorded with BJ compared to those with PLA (13.8 ± 14.4; p 0.05). Acute supplementation of BJ improved muscular endurance performance in RT.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/athletic performancebeet juicedietary supplementergogenic aidnitratenitric oxideAdultAthletic PerformanceBeta vulgarisCross-Over StudiesDietary SupplementsDouble-Blind MethodFruit and Vegetable JuicesHumansMaleMuscle, SkeletalNitratesPerformance-Enhancing SubstancesPlant PreparationsResistance TrainingYoung Adultresearch article32605284open accessAdultoBeta vulgarisEntrenamiento de fuerzaEstudios cruzadosHumanosMasculinoMétodo doble ciegoMúsculo esqueléticoNitratosPreparaciones de plantasRendimiento atléticoSuplementos dietéticosSustancias para mejorar el rendimiento10.3390/nu120719122072-6643PMC7401280https://www.mdpi.com/2072-6643/12/7/1912/pdf?version=1593599182https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7401280/pdf
