Combined training, characterized by the integration of aerobic and resistance exercises, represents an alternative approach to managing type 2 diabetes mellitus (T2DM), although its effects depend on intervention characteristics. This study analyzed the effects of combined training on glycemic control indicators in adults with T2DM through an integrative literature review. Searches were conducted in PubMed/MEDLINE, the Virtual Health Library (VHL), and SciELO, considering publications from 2021 to 2026. Of the 114 records identified, eight studies met the eligibility criteria and were included in the analysis. The findings revealed reductions in glycated hemoglobin (HbA1c), fasting blood glucose, postprandial glucose, and insulin resistance, alongside favorable changes in insulin secretion and glucose utilization. However, the magnitude of these benefits varied across protocols, without consistent evidence that combined training was superior to isolated exercise modalities. Differences were identified regarding intensity, frequency, duration, exercise sequence, and participants' clinical characteristics. Furthermore, reduced adherence following supervised interventions compromised the maintenance of metabolic improvements. Methodological heterogeneity limited the identification of an optimal training configuration. It was concluded that combining aerobic and resistance exercises represents a relevant strategy for glycemic control, provided that individual characteristics and exercise continuity are considered. Individualized exercise prescription and professional supervision are essential to promote sustainable outcomes. Further investigations are necessary to clarify the long-term effects of different training configurations and establish more consistent recommendations for adults with T2DM.
