Abstract

The 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 < 0.01; effect size (ES) = 0.6). Differences were found at 60% 1-RM (9 ± 10; p < 0.05; ES = 0.61) and 70% 1-RM (3.1 ± 4.8; p < 0.05; ES = 0.49), however, no differences were found at 80% 1-RM (1.7 ± 1; p = 0.12; ES = 0.41). A greater number of repetitions was performed in back squat (13.4 ± 13; p < 0.01; ES = 0.77), but no differences were observed in bench press (0.4 ± 5.1; p = 0.785; ES = 0.03). No differences were found for the rest of the variables (p > 0.05). Acute supplementation of BJ improved muscular endurance performance in RT.

  • Ranchal-Sánchez et al. failed to find an effect on muscular velocity and power after NO3− supplementation.

    “In another study, Ranchal-Sánchez et al. [114] observed an enhancement in the number of repetitions to failure (+17.7%) in the sum of sets for bench press and back squat with loads of 60%, 70% and 80% 1RM after NO3− supplementation (BR ingested 2 h prior to exercise), although authors failed to find an effect on muscular velocity and power.”

  • Williams et al. assessed muscle power and velocity during two single explosive repetitions with full recovery (5 min rest between sets), whereas Ranchal-Sánchez et al. assessed power and velocity during sets of repetitions until failure.

    “Indeed, whereas Williams et al. [113] assessed muscle power and velocity during two single explosive repetitions with full recovery (5 min rest between sets), Ranchal-Sánchez et al. [114] assessed power and velocity during sets of repetitions until failure.”

  • The exercise modalities used to assess weightlifting exercise performance were bench press using free weights, bench press using a Smith machine, and box squats using a Smith machine.

  • The procedure used by Ranchal-Sánchez et al. to assess muscle power and velocity may not be suitable to detect a potential effect of NO3− supplementation.

    “Thus, the procedure used by Ranchal-Sánchez et al. [114] to assess muscle power and velocity may not be suitable to detect a potential effect of NO3− supplementation.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
