NCT06734546

Brief Summary

The goal of this clinical trial is to learn if exercise training of high or moderate intensity is most optimal to improve brain health and prevent neurodegeneration in type 2 diabetes patients. The main question it aims to answer is: What is the effect of exercise training of high vs. moderate intensity on brain metabolism, brain perfusion, and cognition in type 2 diabetes? Researchers will compare the exercise training groups to a control group without exercise training to determine the effect of exercise training on the brain in type 2 diabetes. Participants will exercise for 6 months, 3 times per week. Before and after these 6 months, they will undergo:

  • a brain MRI scan
  • cognitive tests
  • blood sampling

Outcome Measures

Primary Outcomes (2)

  • Neurometabolite levels

    Levels of N-acetylaspartate, choline, myo-inositol, creatine, glutathion, and glutamate, measured in institutional units (i.u.) by means of magnetic resonance spectroscopy (MRS).

    From enrollment to the end of treatment at 6 months

  • Changes in arterial spin labelling measured by means of magnetic resonance imaging (MRI)

    Changes in cerebral perfusion expressed in mL/100g/min, and blood flow through the blood-brain-barrier expressed in milliseconds

    From enrollment to the end of treatment at 6 months

Secondary Outcomes (18)

  • Levels of neurodegenerative blood biomarkers

    From enrollment to the end of treatment at 6 months

  • Blood lipid profile

    From enrollment to the end of treatment at 6 months

  • Brain volume

    From enrollment to the end of treatment at 6 months

  • Diffusion-weighted magnetic resonance imaging

    From enrollment to the end of treatment at 6 months

  • Fasted blood glucose

    From enrollment to the end of treatment at 6 months

  • +13 more secondary outcomes

Study Arms (3)

High intensity exercise training group

EXPERIMENTAL

This arm will receive 6 months of exercise training at high intensity (105% VT2)

Other: Exercise intervention

Moderate intensity exercise training group

EXPERIMENTAL

This arm will receive 6 months of exercise training at moderate intensity (60% VT2)

Other: Exercise intervention

Control group

NO INTERVENTION

This arm won't receive exercise training

Interventions
