Dose-Response Effects of Beetroot Juice on Neuromuscular Performance in the Bench Press
Sponsor: Universidad Pontificia Comillas
Summary
Beetroot juice is rich in dietary nitrate, a compound that may improve muscle function and exercise performance. However, the effects of different nitrate doses on upper-body strength and muscular endurance are lees explored. In this randomized, double-blind, placebo-controlled crossover study, participants will complete four experimental conditions involving different doses of beetroot juice (0, 6.4, 12.8, and 19.2 mmol of nitrate from active supplementation) in a randomized order. Each condition will consist of three 70-mL shots (210 mL in total), containing different combinations of nitrate-rich beetroot juice and placebo. Neuromuscular performance will be assessed through bench press exercises at different intensities, evaluating bar movement velocity and muscular endurance. Salivary nitrate and nitrite concentrations, perceived exertion, and potential side effects will also be assessed. The study aims to determine whether increasing doses of beetroot juice produce different effects on neuromuscular performance.

Interventions
Nitrate-Rich Beetroot Juice
Nitrate-rich beetroot juice supplementation administered orally in 70-mL shots, each containing approximately 6.4 mmol of nitrate (NO3-). Participants will receive one, two, or three active shots, corresponding to 6.4, 12.8, or 19.2 mmol of nitrate from active supplementation, respectively. The total volume administered in each experimental condition will be 210 mL, using placebo shots when necessary.
Nitrate-Depleted Beetroot Juice (Placebo)
Nitrate-depleted beetroot juice administered orally in 70-mL shots as a placebo. Participants will receive one, two, or three placebo shots depending on the experimental condition, maintaining a total supplementation volume of 210 mL. The placebo will be used as the control condition and in combination with active beetroot juice to maintain the double-blind design.
