Summary

Researchers are testing whether a 12-week exercise program can improve thinking skills, physical fitness, and quality of life for adults in opioid substitution therapy. Participants are randomly assigned to start exercise right away or after a 12-week wait. The study measures changes in endurance, strength, balance, and cognitive function over up to a year.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a 12-week exercise program with a training contact
What this could lead to
If exercise helps, it could become a low-cost add-on to opioid substitution therapy that supports both physical and mental health.
What could go wrong
The trial is small and early, so any benefits may be modest or not hold up in larger studies. Exercise carries typical risks like muscle soreness or injury, and participants must be stable on their medication.
