Exercise can prevent type 2 diabetes but adherence to the complex behaviour of exercise is poor. Behavioural counseling interventions are effective for increasing long-term exercise adherence. We have developed a short-term behavioural counseling and exercise intervention that may be more practical and feasible for wide-spread dissemination compared with traditional interventions, which are often lengthy and costly. When combined with the novel, time-efficient exercise strategy of high-intensity interval training (HIT), preliminary findings suggest that exercise adherence over the short-term is improved compared to an intervention using standard care continuous moderate-intensity exercise. This trial will test whether a brief behavioural counseling intervention using HIT is superior to traditional continuous moderate-intensity exercise for improving exercise adherence over one-year in individuals who are at risk for type 2 diabetes.
