Abstract:

Introduction: Type 2 Diabetes Mellitus (DM2) is associated with a sedentary lifestyle and leads to systemic responses that increase the risk of morbidity and mortality. High Intensity Interval Training (HIIT) demonstrates improved body composition, glycemic control and cardiorespiratory fitness. Objective: Map the effects of short-interval HIIT on DM2. Materials and Methods: This is a scoping review. As they were published in PubMed, Cochrane Library and Virtual Health Library (BVS) databases with the descriptors “Diabetes mellitus, type 2”, “Glycemic Control”, “High-Intensity interval training” between 03/24/2022 and 31 /03/2022. Eighty-seven articles were identified. After selection of studies and verification of eligibility, 10 articles remained. Additionally, summaries and abstracts were extracted using summary tables and narratives, including publication reviews evaluated using the PED scale, interventions and analyzes using the quality of the Consensus on Exercise Reporting Template (CERT) and the Grading of Recommendations. Assessment, Development and Evaluation (GRADE), respectively. Results: There was a reduction in body weight, body mass index, % body fat, fasting glucose and glycated hemoglobin and an increase in high-density lipoprotein (HDL) after the intervention. Similarly, positive results were found regarding the reduction of low-density lipoprotein (LDL), triglycerides, systolic blood pressure, markers of insulin resistance and medication use. Conclusion: Short-interval HIIT has potential effects for individuals with DM2, especially for metabolic, anthropometric and body composition variables. However, as this is a review with few studies included, caution should be exercised when using HIIT as a complement to treatment.
