Resumen :
Beetroot juice (BJ) contains high levels of inorganic nitrate (NO3) and its intake has good evidence in increasing blood nitrate/nitrite concentrations. The ingestion of BJ has been associated with
improvements in physical performance of endurance sports, however the literature in intermittent
sports is scarce. The aim of this study was to investigate whether BJ could improve physical
performance in tennis players. Thirteen well-trained tennis players (25.4 5.1 years) participated in
the study during their preparatory period for the tennis season. Subjects were randomly divided into
two groups and performed a neuromuscular test battery after either BJ or placebo (PLA) consumption.
Both trials were executed on two separate days, in randomized order, with one week of wash
out period. The test battery consisted of serve velocity test (SVT), countermovement jump (CMJ),
isometric handgrip strength (IHS), 5-0-5 agility test (5-0-5), and 10 m sprint (10-m). No significant
di erences were found in SVT (1.19%; p = 0.536), CMJ (0.96%; p = 0.327), IHS (4.06%; p = 0.069), 5-0-5
dominant and nondominant side (1.11–2.02%; p = 0.071–0.191) and 10-m (1.05%; p = 0.277) when
comparing BJ and PLA ingestion. Thus, our data suggest that low doses of BJ (70 mL) consumption
do not enhance tennis physical performance.
