Beetroot Juice Supplementation in Basketball Players

Whereas beetroot juice (BJ) supplementation is shown to increase physical performance in endurance activities, its benefits in team sports has been barely studied. In this randomized placebo-controlled study, we investigated the effects of BJ acute supplementation in improving neuromuscular performance and physical match activity in basketball.

About this study

Whereas beetroot juice (BJ) supplementation is shown to increase physical performance in endurance activities, its benefits in team sports has been barely studied. In this randomized placebo-controlled study, we investigated the effects of BJ acute supplementation in improving neuromuscular performance and physical match activity in basketball.Testing sessions will comprised a neuromuscular test battery consisting of a countermovement jump (CMJ), isometric handgrip strength, 10-m/20-m sprint and agility T-test, followed by a 40-minute simulated basketball match. Physical match activity (distances, speeds, accelerations and decelerations) will be monitored in real time using an inertial tracking system

Treatment and study plan

Beetroot juice (BJ) acute supplementation

Dietary Supplement

One serving 140 mL of BJ (12.8 mmol of NO3-; Beet-It-Pro Elite Shot, James White Drinks Ltd., Ipswich, UK) after an overnight fast and 3 h before initiating the testing session.

Placebo acute supplementation

Dietary Supplement

One serving placebo drink (0.08 mmol of NO3-; Salud Viva, Nano Salud 32 S.L) after an overnight fast and 3 h before initiating the testing session.

Primary outcomes
