Abstract

Type 2 Diabetes Mellitus (T2DM) case management focuses on maintaining therapeutic goals and improving quality of life. Recent evidence highlights the benefits of high-intensity interval training (HIIT) as a therapeutic treatment in T2DM. However, the relationship remains unclear between the effectiveness of HIIT and T2DM. This study aimed to identify published literature that explored the effectiveness of HIIT on T2DM. We conducted a systematic review of existing literature from electronic databases: Pubmed, Proquest, and Science Direct between 2015-2020 according to PRISMA guidelines. Data were extracted based on the PICOS framework. The methodological quality of these studies was assessed using the Critical Appraisal Skills Programme (CASP) tool. Study bias was assessed using Review Manager 5.3. A total of 11 articles from 503 studies were included. Eleven randomized controlled trials found that HIIT programmes obtain a clinically relevant outcome in reducing blood glucose, improving glycemic control with a reduction in HbA1c, reducing capillary glycemia, and decreasing cardiac function. This review suggests that HIIT is effective and safe for managing T2DM. The evidence consistently demonstrates that HIIT improves health condition and reduce risk factors associated with T2DM. It is critical to encourage further research to establish medium to long-term effects and cost-effectiveness of HIIT among individuals with T2DM.
