Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be recruited using social media and newspapers, they will then be randomized to consume either MitoQ (1 capsule containing mitoquinol mesylate with a total dose of 20 mg of mitoquinol per day) or Ubiquinol (1 Softgel per day which contains 200 mg of CoQ10) in a double-blind manner for a period of 6 weeks for either supplement separated by a six week washout period and then 6 weeks for another supplement .
Participants will visit the laboratory on four occasions, with a muscle biopsy, 24-hour urine and blood sample being collected at each visit, participants will also be assessed for muscle power/strength production using a dynamometer.
High-resolution respirometry will be used to measure mitochondrial function and reactive oxygen species production. Markers of muscle and blood metabolic state and oxidative status will be measured is blood and muscle samples. MitoQ and Ubiquinol capsules will be provided by MitoQ.
Participants will be asked to remain fasted from the night and provide a 3-day eating record before each visit. They will be asked to return drug tablets leftover after each intervention (a period of 6 weeks for each supplement). They will be also asked to wear a wristband for 5 days which tracks the level of physically active.

Statistical methods / analysis
This will be a single centre study involving 20 participants. Sample size was calculated based on the primary outcome of COX1+2 respiration. Previously our group has observed a 13.54 ± 9.78 pmol/mg/s increase in COX1+2 respiration following short term exercise training. Based on detecting an effect of 67% of this magnitude with 80% power 18 participants would be required. A total n of 20 will be recruited to account of potential participant attrition.
A two-way mixed model with both supplement and time as repeated factors with be used for all primary outcomes
