Effect of high-intensity interval training in patients with type 1 diabetes on physical fitness and retinal microvascular perfusion determined by optical coherence tomography angiography.

Objective: Physical activity may protect from ocular complications of diabetic retinopathy (DR). We investigated exercise training effects on the retinal microvasculature using optical coherence tomography angiography (OCTA) in type 1 diabetes (T1D).

Methods: Twenty T1D patients without clinical signs of DR performed four weeks of high-intensity interval training (HIIT).

Four weeks of high-intensity interval training (HIIT) improve the cardiometabolic risk profile of overweight patients with type 1 diabetes mellitus (T1DM).

This study investigated the effects of a four-week HIIT intervention on the cardiometabolic risk profile, liver fat content, insulin requirement, hypoglycaemia, physical fitness, and health-related quality of life in patients with T1DM. A supervised exercise intervention with baseline to follow-up comparison between overweight (BMI = 28.6 ± 2.
