Exercise is one of the most powerful medicines available for type 2 diabetes — comparable to pharmacological intervention in reducing blood sugar levels and superior to medication alone in many metabolic parameters. Physiotherapy-prescribed exercise is a fundament of evidence-based diabetes management.
Why Exercise Is Central to Diabetes Management
Insulin resistance — the core defect in type 2 diabetes — is fundamentally a problem of muscle glucose uptake. Skeletal muscle is responsible for approximately 80% of insulin-stimulated glucose disposal. When muscles are inactive, this capacity is severely reduced. Exercise reverses insulin resistance through:
- Increased GLUT4 transporter expression in muscle cells (improving glucose uptake capacity)
- Improved mitochondrial function in skeletal muscle
- Reduced visceral fat accumulation (the primary driver of insulin resistance)
- Improved insulin signalling pathways
- Reduced systemic inflammation
The Evidence: How Much Does Exercise Reduce HbA1c?
A structured exercise program produces an average reduction in HbA1c (3-month blood sugar marker) of 0.5–0.7%. This is comparable to the effect of many first-line oral diabetes medications. Combining aerobic and resistance training produces greater reductions than either alone. For people with prediabetes, structured exercise can prevent or delay progression to type 2 diabetes by over 50%.
Exercise Prescripton for Diabetes
Current evidence-based guidelines recommend:
- 150 minutes per week of moderate-intensity aerobic exercise (brisk walking, cycling, swimming)
- Resistance training 2–3 sessions per week covering all major muscle groups
- Avoiding prolonged sitting — breaking sitting every 30 minutes with light activity
- Starting at low intensity and progressing carefully — particularly for those with cardiovascular risk factors or complications

Frequently Asked Questions
How does exercise lower blood sugar?
Exercise improves blood sugar in several ways: (1) During exercise, muscle cells take up glucose directly from the blood without needing insulin — providing immediate blood sugar reduction; (2) Resistance training builds muscle mass, increasing the overall capacity for glucose uptake and storage; (3) Regular aerobic exercise improves insulin sensitivity — meaning the body's existing insulin works more effectively; (4) Exercise reduces visceral adiposity (the dangerous abdominal fat around organs) which drives insulin resistance.
What type of exercise is best for diabetes?
Current guidelines recommend a combination of: aerobic exercise (brisk walking, cycling, swimming) 150+ minutes per week at moderate intensity, and resistance training 2–3 times per week targeting major muscle groups. Breaking up prolonged sitting with short activity breaks also improves glucose regulation. A physiotherapist will assess your fitness and any complications (peripheral neuropathy, cardiovascular disease) to design a safe, effective program.
What precautions do people with diabetes need for exercise?
Blood glucose monitoring before and after exercise is important for people on insulin or sulfonylureas — to prevent hypoglycaemia. Carry glucose or a snack. Foot care is critical — wear appropriate shoes, inspect feet for blisters or wounds before and after exercise. Avoid exercise if blood glucose is above 15–17 mmol/L or below 4 mmol/L. A physiotherapist experienced in diabetes exercise can provide specific guidance for your situation.
Can physiotherapy help with diabetic peripheral neuropathy?
Yes. Peripheral neuropathy (nerve damage causing numbness, tingling, and pain in the feet and legs) is a serious diabetes complication that affects balance and increases fall risk. Physiotherapy provides balance training to reduce fall risk, specific exercise programs that can slow neuropathy progression, footwear advice, and foot care education. Exercise also improves nerve blood flow, which may slow neuropathy progression.
