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. Ten young male competitive basketball players aged 15-16 years received 140 mL of BJ or placebo (PLA) on two separated days in a balanced cross-over design. Testing sessions 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) was monitored using an inertial tracking system (Wimu Pro TM ) Results revealed no significant effects of BJ on CMJ ( p = 0.304, ES = 0.13), isometric handgrip strength ( p = 0.777, ES = 0.06), 10-m ( p = 0.820, ES = 0.10), and 20-m sprint ( p = 0.540, ES = 0.13), agility T-test ( p = 0.979, ES ≤ 0.01) and any physical match demands ( p &gt; 0.151, ES = 0.13-0.48). Acute moderate doses of BJ (12.8 mmol of NO 3  - ) was not effective in improving neuromuscular performance (jump height, isometric handgrip strength, sprint, and agility) or physical match requirements in young trained basketball players the day of the competition.
