Efficacy of Exercise Snacks in Real-World Settings in Individuals Living With Type 2 Diabetes

Summary

To conduct a pilot randomized control trial to determine the feasibility of a 12-week, technology-enabled exercise snacks intervention in adults living with type 2 diabetes in a real-world setting. We will also assess preliminary efficacy based on measures of glycemic control and fitness.

5. Taking ≤3 glucose-lowering medications (excluding insulin) and stable dose for \> 6 months.
6. Taking ≤2 commonly prescribed cardiovascular medications (e.g., statins, antihypertensive).
7. HbA1c ≤8.5%.
8. Able to maintain current physical activity patterns during the study.
