Summary:
In patients with type 2 diabetes mellitus, a combined exercise program significantly reduced abdominal fat and improved sleep quality compared to no structured exercise intervention,
though it was associated with no significant adverse effects.
PICO
Description
Population
Patients with type 2 diabetes mellitus experiencing abdominal fat accumulation and poor sleep quality.
Intervention
A combined exercise program focused on aerobic activity and resistance training.
Comparison

⬡ Bottom Line
In older adults with type 2 diabetes, a 12-week combined aerobic-plus-resistance program significantly cut visceral and subcutaneous abdominal fat and improved sleep quality, with no significant adverse effects. It was the only programme to improve objective sleep measures.
