Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Scientific evidence supports that only a few dietary supplements have reported good evidence for improving sports performance, between we can mention beetroot juice supplementation with doses \> 5 mmol of NO3-. In this randomized placebo-controlled study, we investigated the effects of BJ acute supplementation in improving neuromuscular performance and match-play demands in female field hockey players.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Beetroot juice supplementation has demonstrated good evidence for improving sports performance, however, benefits in team sports, especially in female athletes, are underrepresented. In this randomized placebo-controlled study, we investigated the effects of beetroot juice acute supplementation in improving neuromuscular performance and match-play demands.Testing sessions will comprise a neuromuscular test battery consisting of a countermovement jump (CMJ), isometric handgrip strength, 20-m sprint and repeated sprint ability test, followed by a 20-minute simulated field hockey Physical match activity (distances, speeds, accelerations and decelerations) will be monitored in real-time using an inertial tracking system
