Exercise is a cornerstone in the management of diabetes, especially type 2 diabetes, and has far-reaching benefits that extend beyond blood sugar control. For individuals living with diabetes, incorporating regular physical activity into their lifestyle can significantly improve glycaemic control, cardiovascular health, and overall quality of life. Let’s delve into the importance of exercise for diabetics.

The Role of Exercise in Managing Diabetes

For individuals with diabetes, the American Diabetes Association (ADA) advises a minimum of 150 minutes of moderate-intensity aerobic exercise weekly. This recommendation stems from the crucial role of exercising in enhancing the body's insulin efficiency, which is vital for maintaining stable blood sugar levels.

A 2020 study in Diabetologia highlighted the significant impact of structured exercise. It found that type 2 diabetic patients experienced an average reduction of 0.7 per cent in their HbA1c levels through exercise training, a result comparable to the effects of some medications.

Even for those with type 1 diabetes, where insulin remains essential, exercise improves insulin sensitivity and boosts glucose absorption by muscles. This contributes to better blood sugar management and lowers the risk of long-term complications.

Evidence-Based Benefits of Exercise for Diabetics

• Improved Glycaemic Control: A systematic review in The Lancet Diabetes & Endocrinology (2016) found that aerobic exercise, resistance training, or a combination of both significantly reduced HbA1c levels.
• Weight Management: Obesity is a major risk factor for insulin resistance. Physical activity helps burn calories and promotes fat loss, particularly visceral fat, which is closely linked to diabetes progression.

• Reduced Risk of Cardiovascular Disease: The UK Prospective Diabetes Study (UKPDS) found that managing blood pressure and engaging in regular physical activity reduces the risk of stroke, heart attack, and cardiovascular mortality in diabetic patients.
   
• Improved Mental Health: Exercise releases endorphins, which can improve mood and reduce depression and anxiety, conditions commonly experienced by those managing chronic diseases.
   
• Enhanced Mobility and Lower Risk of Neuropathy: Diabetics often face risks of diabetic neuropathy and foot ulcers. Weight-bearing and balance exercises can help reduce falls and improve peripheral circulation.

What Kind of Exercise Is Best?

• Aerobic Exercises: Walking, swimming, cycling, or dancing improves heart health and lowers blood glucose.
• Resistance Training: Using weights or resistance bands builds muscle mass and improves insulin sensitivity.
• Flexibility and Balance Exercises: Yoga and tai chi, which are slow and gentle martial arts, help in reducing stiffness and improving posture and coordination.

The NHS recommends a mix of aerobic and strength-building exercises for those living with diabetes, particularly for older adults, to enhance mobility and prevent weakness in the body. 

Safety Tips Before Exercising

• Monitor Blood Sugar: Check sugar levels before and after your workout.
• Carry Fast Carbs: Always have glucose tablets or other fast-acting carbohydrates for hypoglycemia.
• Hydrate & Protect: Stay well-hydrated and wear appropriate footwear to prevent injuries.
• Consult Your Doctor: Speak with your GP or diabetes care specialist before starting any new fitness program.

Regular exercise for people with diabetes is not merely a lifestyle recommendation; it's a science-backed intervention with proven benefits for long-term health outcomes. From improved blood sugar levels to better mental well-being, the advantages are holistic. As more research emerges, it becomes increasingly clear that movement is indeed medicine, particularly for those managing type 1 or type 2 diabetes.
