Beetroot Juice Supplementation in Basketball Players

Not Applicable

Completed

• Conditions: Dietary Supplement; Sport Performance
• Interventions: Dietary Supplement: Beetroot juice (BJ) acute supplementation; Dietary Supplement: Placebo acute supplementation

• Registration Number: NCT04210531
• Lead Sponsor: Universidad de Murcia

Brief Summary

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.

Detailed Description

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
