Not Applicable

Completed

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

• Registration Number: NCT05210244
• Lead Sponsor: Universidad Francisco de Vitoria

Brief Summary

Whereas beetroot juice (BJ) supplementation is shown to increase physical performance in endurance activities, its benefits in neuromuscular function and strength performance has been barely studied. In this cross-over randomized placebo-controlled study, we investigated the effects of BJ acute supplementation in improving neuromuscular performance in amateur climbers
