Key finding
Fasting insulin decreased relative to control in A+R (MD -8.87 mIU/L; 95% CI -11.77 to -5.97).
This study compared the effects of combined aerobic-resistance training and high-intensity interval training on adults with type 2 diabetes. Both interventions showed significant improvements in fasting insulin and HbA1c levels compared to standard care.

Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
This study compared the effects of combined aerobic-resistance training and high-intensity interval training on adults with type 2 diabetes. Both interventions showed significant improvements in fasting insulin and HbA1c levels compared to standard care.
These findings are significant for managing type 2 diabetes, as they suggest that specific exercise regimens can lead to meaningful reductions in insulin resistance and blood sugar levels. This could help guide healthcare providers in recommending tailored physical activity programs to improve metabolic health in diabetic patients.
The sample size may limit the generalizability of the findings. The study did not measure long-term effects of the interventions. Potential confounding factors were not fully controlled.
