About the trial

What the trial wants to find out

The overarching aim of this intervention study is to interrogate the interconnection between the muscle mitochondrial adaptations and the changes in muscle insulin sensitivity elicited by exercise training in individuals harbouring pathogenic mitochondrial DNA mutations associated with an insulin-resistant phenotype.

Read full original descriptionShow less

In a within-subject parallel-group longitudinal design, participants will undergo an exercise training intervention with one leg, while the contralateral leg will serve as an inactive control. After the exercise intervention, patients will attend an experimental trial including:

* A hyperinsulinemic-euglycemic clamp combined with measurements of femoral artery blood flow and arteriovenous difference of glucose * Muscle biopsy samples

The 2 groups in the trial

  • Exercise legTreatment being tested

    High-intensity exercise training for one leg

    Treatment: High-intensity exercise training

  • Control legNo study treatment, for comparison

    No exercise training for the controlateral leg
