Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study contains two arms; treatment (Arm 1) and placebo (Arm 2). Participants in Arm 1 will be asked to consume one MitoQ oral capsule (containing mitoquinol mesylate equivalent to 20mg mitoquinol) per day for 5 weeks. Adherence to the supplement protocol will be monitored via tablet return.

Participants in both arms will undergo high intensity interval exercise training. Participants will be asked to come to the University of Auckland Grafton campus to complete 10 face-to-face training sessions over a period of 3 weeks, which will be supervised by the researcher. During the first week participants will complete 3 sessions of 8 repeated 60s intervals of high-intensity stationary cycling (at 100% peak power output determined from VO2max test) with 75 s of recovery between each repetition .Training sessions in the first week are expected to last around 30 minutes, including a 5 minute warm-up and 5 minute cool down. During the second week participants will complete 3 sessions of 10 repeated 60s intervals of high-intensity stationary cycling (at 100% peak power output determined from VO2max test) with 75 s of recovery between each repetition. Training sessions in the second week are expected to last around 35 minutes, including a 5 minute warm-up and 5 minute cool down. During the third week participants will complete 4 sessions of 12 repeated 60 s intervals of high-intensity stationary cycling (at 100% peak power output determined from VO2max test) with 75 s of recovery between each repetition. Training sessions in the third week are expected to last around 40 minutes, including a 5 minute warm-up and 5 minute cool down. Training sessions will be separated by at least one day and no more than 4 days,

Type of endpoint(s)
Statistical methods / analysis
Based on performance data generated in our laboratory, there was an average 9% increase in v02max with and SD of 2.7, the current study is powered to detect a 30% difference in the increases in VO2max (11.76% increase) with 15 subjects per group and 80% power. Appropriate recruitment will allow for drop outs.

ANOVA or non-parametric tests where appropriate and followed up with post-hoc tests will be used to determine differences in end points. Significance will be accepted at P<0.05.

Summary
Brief summary
The purpose of this study is to evaluate the effect of MitoQ supplementation on exercise training induced adaptations and exercise performance. Furthermore, the study aims to evaluate the effect of MitoQ supplementation on the cellular signalling response to a single bout of exercise and biomarkers which can be used to assess skeletal muscle and metabolic health following multiple (training) bouts of high intensity interval exercise. Finally, the study will enable the researchers to identify novel biomarkers which can be used to assess skeletal muscle and metabolic health, and the response to high intensity interval exercise.

We hypothesise that multiple (training) sessions of high intensity interval exercise will improve exercise performance and this will be enhanced by MitoQ supplementation. Furthermore, enhanced exercise performance in the MitoQ supplemented group will be associated with elevated cellular signalling and biomarkers of skeletal muscle and metabolic health.
