Brief summary
A single arm, interventional study with 12 weeks study phase preceded by a 2-week run in phase, aiming to evaluate the effectiveness and applicability of the Tandem Mobi automated insulin delivery system (Tandem Mobi Pump System) for competitive youth athletes with type 1 diabetes in real-world conditions.
Interventions
Tandem Mobi Hybrid Closed Loop (HCL) pump with an integrated Control-IQ algorithm (CIQ), the Dexcom G7 continuous glucose monitoring sensor (CGM ) and Tandem Mobi Mobile App

Eligibility
Inclusion criteria
* Type 1 diabetes (T1D) for at least 6 months * 11≤Age≤18 years * HbA1c \<10.0% * Current treatment with automated insulin delivery system (AID) or insulin pump for at least 1 month * Willing to switch to Tandem Mobi Pump System and Dexcom CGM for the study duration * Competitive-level athletes
Exclusion criteria
* Concomitant disease that influences metabolic control or HbA1c interpretation * Individual has any unresolved adverse skin condition in the area of sensor or device placement (e.g., psoriasis, rash, Staphylococcus infection) * Use of antidiabetic agents other than insulin * Two or more episodes of severe hypoglycemia (hypoglycemia requiring treatment by another person) within the previous 6 months * One or more episodes of ketoacidosis requiring hospitalization within 6 months prior to screening * Individual has a positive pregnancy screening test
