A multidisciplinary evaluation of a virtually supervised home-based high-intensity interval training intervention in people with type 1 diabetes

Abstract

OBJECTIVE Adopt a multidisciplinary approach to evaluate a virtually supervised home-based high-intensity interval training (Home-HIT) intervention in people with type 1 diabetes. RESEARCH DESIGN AND METHODS Eleven individuals with type 1 diabetes (seven women; age 30 6 3 years; V· O2peak 2.5 6 0.2 L/min; duration of diabetes 10 6 2 years) completed 6 weeks of Home-HIT. A heart rate monitor and mobile phone application were used to provide feedback to the participants and research team on exercise intensity (compliance) and adherence. RESULTS Training adherence was 95 6 2%, and compliance was 99 6 1%. Home-HIT increased V· O2peak by 7% (P 5 0.017) and decreased insulin dose by 13% (P 5 0.012). Blood glucose concentration did not change from baseline to immediately or 1 h post Home-HIT. Qualitative perceptions of Home-HIT and the virtual-monitoring system were positive, supporting that the intervention successfully removed exercise barriers in people with type 1 diabetes. CONCLUSIONS Virtually monitored Home-HIT resulted in high adherence alongside increased V· O2peak and decreased insulin dose.
