Why the study?
The study evaluated the effect of 12 weeks of high-intensity interval training on glycemic control in adults with type 1 diabetes and overweight or obesity.
Does 12 weeks of high-intensity interval training (HIIT) improve glycemic control in inactive adults with type 1 diabetes and overweight or obesity?
Population

Comparison
12 weeks of HIIT thrice weekly vs usual care control
Design
Randomized controlled trial with partial crossover
Follow-up
24 weeks

HIIT does not improve HbA1c in overweight adults with type 1 diabetes; challenges assumptions of broad glycemic benefit and leaves open optimized exercise strategies.
Does 12 weeks of high-intensity interval training (HIIT) improve glycemic control in inactive adults with type 1 diabetes and overweight or obesity?
A 12-week high-intensity interval training intervention did not significantly reduce HbA1c in adults with type 1 diabetes and overweight or obesity compared to usual care, though adherence may influence outcomes.
