High-intensity interval training (HIIT) induces skeletal muscle molecular adaptations, including increased GLUT-4 content and mitochondrial biogenesis, which improve glucose disposal and insulin sensitivity in patients with metabolic diseases.

If you have metabolic issues like type 2 diabetes, high-intensity interval training (HIIT) can significantly improve how your muscles handle glucose. This involves short bursts of vigorous activity followed by rest, which increases GLUT-4 proteins and mitochondrial function. Consult your doctor to ensure it is safe for you, then consider protocols that challenge your peak heart rate (80-95% HRmax) for intervals of 1-4 minutes.

Skeletal muscle is the primary site for glucose disposal via insulin- and non-insulin-mediated glucose uptake... Increased GLUT-4 content in the vastus lateralis increased by 369% following six sessions of HIIT in type 2 diabetes patients [12].
