Dietary Supplement, Sport Performance
Conditions
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
Interventions
DIETARY_SUPPLEMENTBeetroot juice (BJ) acute supplementation
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.
DIETARY_SUPPLEMENTPlacebo acute supplementation
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.
