What this trial studies

This interventional study investigates how the timing and type of exercise affect glycemic regulation in adolescents aged 10 to 16 living with type 1 diabetes. Participants will engage in either continuous or intermittent exercise sessions scheduled in the morning or afternoon. The study aims to determine the optimal exercise conditions for maintaining stable blood glucose levels during and after physical activity. It is a randomized, controlled trial conducted at a single center, focusing on minimal risks and constraints for participants.

Who should consider this trial

Good fit: Ideal candidates are adolescents aged 10 to 16 with type 1 diabetes for at least one year and an HbA1c of 12% or lower.

Not a fit: Patients with significant microvascular complications or other serious medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved exercise guidelines for adolescents with type 1 diabetes, enhancing their glycemic control.

How similar studies have performed: While studies on exercise and diabetes management exist, this specific focus on circadian rhythm and exercise type in adolescents is relatively novel.
