简要总结
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.
详细描述
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.

排除标准

- •Lack of internet access.
- •Angina upon exertion assessed by the Rose Angina Questionnaire.
- •Prescribed beta-blockers that can compromise the validity of heart rate measurements. during the submaximal exercise test.
- •Have uncontrolled high blood pressure (hypertension; ≥ 160/90 mmHg) or an atypical blood pressure or pulse rate at rest or during exercise as determined by a physician.
- •Have a scheduled surgical procedure within the next 3-4 months that would prevent exercise participation.
- •Currently diagnosed with a cardiac or pulmonary disease (e.g., angina, arrythmia, exercise-induced bronchospasm) that would prevent exercise participation.
- •Have a psychiatric disorder that could prevent you from completing the study procedures or visits.
- •Have donated more than 0.5 L of blood within the last 4 weeks.
- •Currently following an extreme diet (e.g., very low carbohydrate/calorie, ketogenic) or taking dietary/nutritional supplements that impact glucose control (e.g., exogenous ketones).
- •Currently have diabetic ulcers, peripheral vascular disease, or diabetic neuropathy that will prevent participation in exercise.

- •Currently on dialysis.
- •Currently pregnant or planning on becoming pregnant during the intervention (i.e., within the next 4 months).
- •Have had an episode of severe hypoglycemia in the past 6 months (defined as having neurological symptoms consistent with neuroglycopenia and required assistance in treatment by a second party).
