About this study

The goal of this clinical trial is to learn if CoQ10 amplifies endurance training-induced myokine and exerkine secretion and if those changes influences cognition in long-distance runners.

Does 4-week high-dosage CoQ10 supplementation increase the secretion of myokine, exerkine sercetion? Does the above-mentioned intervention improve the cognitive function in long distance runners?

Participants will:

Take CoQ10 or a placebo every day for 4 weeks. Visit the laboratory once every 4 weeks for checkups and tests. Keep the participants' food and training diary.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CoQ10 supplementationDietary supplement

    Long-distance runners will be supplemented with CoQ10 for 4 weeks in cross-over manner with 4 weeks of wash out period.

  • Placebo supplementationDietary supplement

    Long-distance runners will be supplemented with placebo for 4 weeks in cross-over manner with 4 weeks of wash out period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in cognitive funtions as a result of CoQ10 supplementation measured via cogntitive function test.

    The investigators assume that supplementation with CoQ10 will change cognition (measured via cognitive function tests - Stroop Test, Trial Making Test A and Trial Making Test B) in long-distance runners. The results will be obtained as time (seconds) needed to complete tasks while testing.

    Measured: The investigators are going to check this hypothesis after 4 weeks of high-dose supplementation with CoQ10

  2. Change in myokine and exerkine concentration in the blood plasma as a result of CoQ10 supplementation.

    The investigators will assess the concentration of blood myokine and exerkine concentration (pg or ug/dl) of blood plasma using the colorimetric method.

    Measured: The investigators are going to check this hypothesis after 4 weeks of high-dose supplementation with CoQ10

Secondary outcomes (1)
  1. Change in aerobic capacity measured via direct test to volitional exhaustion on a motorized treadmill

    The investigators assume that supplementation with CoQ10 will change the aerobic capacity (oxygen uptake in ml-1 x min-1 x kg-1) in long-distance runners. The determination of aerobic capacity will be done through progressive test to volitional exhaustion on a motorized treadmill and gas analyzer

    Measured: The investigators are going to check this hypothesis after 4 weeks of high-dose supplementation with CoQ10

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing CoQ10 supplementation in people with Health Knowledge, Attitudes, Practice, run by Gdansk University of Physical Education and Sport 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 3 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: status not confirmed, as of the sponsor's last update on 26 Aug 2025. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in cognitive funtions as a result of CoQ10 supplementation measured via cogntitive function test. (time frame: The investigators are going to check this hypothesis after 4 weeks of high-dose supplementation with CoQ10). 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?
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 26 Aug 2025.
