Clinical Trial Summary

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.


Description:

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
