About this study
Official title: Acute Effects of Beetroot Juice Ingestion on Neuromuscular Performance and Match-play Demands in Elite Female Hockey Players.
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.
Read the detailed 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

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes in simulated field hockey match demands (m/min) (time frame: 1 week). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05209139, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Apr 2022.
