About this study
Official title: Analysis of Electromyography Activation Trunk Muscles and the Effect of Beetroot Juice Intake on the Results in Strength Exercises: Lateral Medicine Ball Throw and Sled Pushing
The primary aim of the current study is determine the effect of beetroot juice consumption on maximal grip strength and EMG muscle activity
Read the detailed description
In random order subjects will consume high nitrate beetroot juice or low level of nitrate beetroot juice. Grip strength and EMG will be measured at the beginning and repeated after 2h.
Using blood pressure cuff, occlusion will be induced to restrict blood flow in the brachial artery. Following the deflation of the cuff, assessments will be conducted for grip strength and electromyography (EMG) activation of the forearm muscles. These measurements will be taken both initially and after a 2-hour interval.

Questions about this trial
What is this clinical trial studying?
A study testing Beetroot juice in people with Muscle Strength, run by Poznan University of Physical Education at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 17 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
The effect of Beetroot Juice consumption on Grip Strength (time frame: 2 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 17 Aug 2026.
