About this study
Official title: Evaluation of Various Doses of Beetroot Juice on Anaerobic Performance
The purpose of this study is to examine the effect of varying nitrate doses of beetroot juice supplementation on dynamic, multijoint resistance exercise performance in active, trained individuals. Performance will be assessed based on parameters including neuromuscular efficiency, anaerobic performance capability, oxygen consumption, plasma nitrate/nitrite levels, specific muscle tissue biomarkers including lactate, and anthropometric measurements of select muscle groups.
- Conditions
- Anaerobic Exercise, Dietary Supplementations
- Being tested
- Beet It Sport Shot, Placebo
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Beet It Sport ShotDietary supplement
Commercially available concentrated beetroot juice supplement intended for athletes.
PlaceboOther
Fruit juice cordial containing negligible nitrate
| Study group | Role | What they receive |
|---|---|---|
| High Dosage | Active comparator | Subjects will receive approximately 8 mmol of dietary nitrate per day delivered as a commercially available beetroot juice supplement for 7 days. Receives: Dietary Supplement: Beet It Sport Shot |
| Moderate Dosage | Active comparator | Subjects will receive approximately 0.5 mmol of dietary nitrate per day delivered as a commercially available beetroot juice supplement for 7 days. Receives: Dietary Supplement: Beet It Sport Shot |
| Placebo | Placebo comparator | Subjects will receive a placebo beverage containing negligible nitrate for 7 days. Receives: Other: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Muscle activation and fiber recruitment
Muscle activation/fiber recruitment to be measured in millivolts (mV) using electromyography (EMG) sensor during maximum voluntary contractions (MVC) and compared between study arms.
Measured: 5 weeks
Secondary outcomes (3)
Plasma nitrate/nitrite levels
Plasma nitrate and nitrite levels will be measured at baseline and after 7 days of supplementation and compared between study arms.
Measured: 5 weeks
Number of repetitions performed
Total number of repetitions in each session and number of repetitions performed at each respective % of 1 repetition maximum during each session will be recorded and compared between study arms.
Measured: 5 weeks
Oxygen consumption
Total oxygen consumption during testing sessions will be recorded and compared between study arms.
Measured: 5 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Beet It Sport Shot in people with Anaerobic Exercise and Dietary Supplementations, run by University of Manitoba at 1 site in Canada.
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 2 inclusion and 2 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 31 Jan 2020. 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 Canada. 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?
Muscle activation and fiber recruitment (time frame: 5 weeks). 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 31 Jan 2020.
