A Phase 4 interventional study of CoQ10 supplementation and Placebo supplementation in Health Knowledge, Attitudes, Practice, sponsored by Gdansk University of Physical Education and Sport. Recruiting at 1 site in Poland. Open to male participants aged 30 Years to 50 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-08-26.

Study summary

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 researchers measure

Primary outcomes

  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.

    Time frame: 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.

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

Secondary outcomes

  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

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