Walking vs. weights: which exercise helps blood sugar in menopausal women with type 1 diabetes?
NCT ID NCT05188027
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how different types of exercise—walking and weight-lifting—affect blood sugar levels in post-menopausal women with type 1 diabetes. Twenty participants will wear a continuous glucose monitor and complete three sessions: one with aerobic exercise, one with resistance exercise, and one resting. Researchers will track blood sugar changes during and after exercise to better understand how to manage diabetes in this group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- aerobic exercise (walking) and resistance exercise (weight-lifting)
- What this could lead to
- If successful, this study could help tailor exercise recommendations for post-menopausal women with type 1 diabetes to better manage blood sugar levels.
- What could go wrong
- This is a small, early-phase study with only 20 participants, so results may not apply to all. Exercise can also cause unpredictable blood sugar changes, including hypoglycemia.
