Exercise is one of the most powerful tools for managing diabetes and protecting cardiovascular health. Yet for many people with diabetes \u2014 particularly those on insulin or sulfonylureas \u2014 the fear of hypoglycaemia during or after exercise is a genuine barrier to physical activity. Understanding how different types of exercise affect blood glucose allows you to train safely and confidently.<\/p>\n<\/div>\n

How Exercise Affects Blood Glucose<\/h2>\n

The relationship between exercise and blood glucose is complex and depends on the type, intensity, and duration of activity. Aerobic exercise<\/strong> (moderate-intensity, sustained cardio) generally lowers blood glucose by increasing glucose uptake in muscle cells \u2014 an insulin-independent process mediated by GLUT4 transporters. This effect can persist for 24\u201348 hours after exercise, increasing the risk of delayed hypoglycaemia.<\/p>\n

High-intensity interval training (HIIT)<\/strong> and resistance training<\/strong> can actually cause a transient rise in blood glucose due to the release of counter-regulatory hormones (adrenaline, cortisol, glucagon) that stimulate hepatic glucose production. This makes them potentially safer for those prone to exercise-induced hypoglycaemia.<\/p>\n
