HIIT vs steady exercise: which works better for prediabetes?
NCT ID NCT06831266
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at two different exercise programs in 24 adults with prediabetes (higher than normal blood sugar but not yet diabetes). One group did short bursts of intense exercise (HIIT), the other did steady moderate exercise. Researchers measured changes in blood sugar, cholesterol, body composition, and quality of life over 12 weeks to see which approach works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- exercise training (high-intensity interval training and moderate-intensity continuous training)
- What this could lead to
- If successful, this could show which exercise type is more effective at preventing progression from prediabetes to type 2 diabetes.
- What could go wrong
- This is a small, completed study with only 24 participants, so results may not apply to everyone. Exercise interventions also depend on long-term adherence.
