Study: when you exercise matters for blood sugar control in type 1 diabetes
NCT ID NCT07365176
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how different types of exercise—short bursts of intense cycling versus steady moderate cycling—affect blood sugar levels in adults with type 1 diabetes. It also compared exercising after a meal versus on an empty stomach. Twenty-one physically active adults completed four cycling sessions, and their blood sugar was tracked during and for 24 hours after exercise. The goal was to find the safest and most effective way to exercise without causing dangerous drops in blood sugar.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- exercise (high-intensity interval and moderate-intensity continuous cycling)
- What this could lead to
- If successful, this could help people with type 1 diabetes better manage their blood sugar during and after exercise by choosing the right type and timing.
- What could go wrong
- This is a small, early-stage study with only 21 participants, so results may not apply to everyone. Exercise always carries some risk of blood sugar drops in type 1 diabetes.
