The Diabetes Aerobic and Resistance Bands Exercise (DARE-Bands) Trial (DARE-Bands)
Type 2 Diabetes
About this trial
This is an interventional treatment trial for Type 2 Diabetes focused on measuring Diabetes Mellitus, Type 2 Diabetes Mellitus, Resistance Training, Resistance Exercise, Resistance Band, Thera-band, elastic band, exercise band
Eligibility Criteria
Inclusion Criteria:
- Adults aged >35 years with T2D as defined by the CDA Expert Committee.
- A1C values within range of 6.6%-9.9%.
- Willingness to follow study procedures (e.g. wear the accelerometer for exercise sessions and download them at least weekly, complete exercise logs, attend supervised group-based resistance band sessions, perform resistance bands exercise at home).
Exclusion Criteria:
- Participation in a regular program of physical conditioning or aerobic sports/activities for >150 minutes per week during the 6 months prior to enrolment.
- Participation in any resistance exercise training during the previous 6 months.
- Requirement for insulin therapy currently or in the previous 3 months.
- Uncontrolled hyperglycemia (A1C > 10%), as it would be a clear indication for cointervention.
- Uncontrolled hypertension: systolic BP >160 mmHg or diastolic BP >100 mmHg, both measured in sitting position. If too-high A1C or BP is the only reason for exclusion, subjects will be asked to see their physicians regarding the hyperglycemia or BP, and invited to re-apply for the study several months later if the problem is under better control.
- Hypo-glycemia unawareness, or severe hypoglycemia requiring assistance from another person within the previous 3 months.
- Restrictions in physical activity due to disease: unstable cardiac or pulmonary disease, severe aortic stenosis, Marfan's syndrome (risk of aortic dissection from resistance training), intermittent claudication sufficient to interfere with aerobic exercise progression, severe peripheral neuropathy or active proliferative retinopathy, disabling stroke, severe arthritis, musculoskeletal injuries compromising safety of the prescribed exercises, inability to walk 10 minutes.
- Other illness, judged by the patient or study physician to make participation in this study inadvisable.
- Inability to understand or comply with instructions.
- Pregnancy at the start of the study, or intention to become pregnant in the next 6 months.
- Plans to move to a different city within the next 12 months.
- Inability to communicate in English or French.
- Unwillingness to sign informed consent.

Experimental
Aerobic Training (AT) only
AT plus Primarily Home-Based Resistance Band Training
All subjects will participate in a 10-week ramp-in period with the goal of achieving 150 minutes of moderate-to-vigorous physical activity per week. Walking and jogging will be the primary modes of achieving the prescribed aerobic activity as these are the modes of aerobic exercise that are most accurately recorded by an accelerometer. Subjects will use the Rate of Perceived Exertion (RPE) to guide aerobic exercise intensity. Aerobic activity will be objectively monitored by the Technogym MyWellness Key (MWK) accelerometer, which is a lightweight device worn on the waistband.
Both of the bands + AT groups will engage in RBT 3 times per week, progressing to 3 sets of 8-12 repetitions of 12 exercises. The exercises will be: chair squat, sitting chest press, seated rear fly, seated row, overhead press, lateral raise, biceps curl, triceps extension, leg extension, hamstring curl, gluteal extension, and abdominals. The resistance band exercise sessions will be between 25-60 minutes. Participants in this group will attend supervised group sessions weekly in weeks 1-4, every 2 weeks in weeks 5-8, and every 4 weeks thereafter to ensure proper form and appropriate progression. Participants in this group will be responsible to complete all remaining sessions (a total of 3 per week, including supervised sessions) at home on their own time.
