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.
Participants will be randomized into an Exercise Snacks or a Placebo Exercise group for 12 weeks. The former will involve bodyweight exercises performed with vigorous effort and the latter will involve low-intensity exercises. Following baseline testing, individualized interventions will be delivered at home or work via customized mobile application ("app") or web platform. Participants will be instructed to perform a minimum of 4 isolated bouts of prescribed exercises per day on at least 5 days per week. Each bout will be one minute in duration. The interventions will be individualized and consider exercise preferences and physical abilities (e.g., fitness, musculoskeletal issues), and be adaptable to multiple environments (e.g., home, work). To facilitate this, participants will have a pre-intervention meeting wherein any physical limitations will be documented, and a research assistant will discuss the prescribed intervention and determine when and where the participants will plan to perform their exercises. After 12 weeks, participants will be asked to return to the lab for follow-up testing.
