The article describes the benefits of exercises for diabetics patients. The best and suitable exercises for diabetics patients are demonstrated with aid of videos.
Diabetes is one of the most prevalent lifestyle diseases in modern world but still the awareness about the risks and benefits of exercises to patients with diabetes is limited. There are two distinct types of diabetes mellitus: lnsulin dependent (type 1) and Non insulin dependent (type 2) with distinct challenges associated with exercises.
It is an inherited autoimmune disease in which antibodies are produced against the beta cells of pancreas. Type 1 diabetes represents approximately 10-15% of the diabetic cases. It is characterized by absence of endogenous insulin production. Therefore insulin administration is essential to prevent ketosis, coma, and death.

Type 2 diabetes is linked to both genetic and lifestyle factors, It is characterized by diminished insulin secretion relative to serum glucose levels in conjunction with peripheral insulin resistance, both of which result in chronic hyperglycemia. Type 2 diabetes is characterized by three major metabolic abnormalities:
When considering exercise prescription for a diabetic patient target should be to achieve at least 30 minutes of continuous moderate activity (e.g. brisk walking) five or six days a week provided that cardiovascular and hypertensive problems are accounted for.
Both insulin and exercise independently facilitate glucose transport across the mitochondrial membrane and their action is also cumulative, therefore special care must be taken in patients taking insulin. Other points that should be taken care of include:
Exercises for diabetics can significantly reduce the risk of developing Type 2 diabetes. In patients, exercise can help to reduce insulin requirements in two ways. It increases the body’s sensitivity to insulin and it enhances the more efficient utilization of glucose. Exercise helps lower blood sugar levels. Therefore it can help to maintain overall diabetic control.
Type 1 diabetes
Type 2 diabetes
It is important to monitor blood sugar levels before, during and after exercise. The meal plan and insulin dosage should be adjusted according to patients response to exercises. The ideal pre exercise blood glucose level is 6.6-10mmol/L (120-180mg/dL). Athletes with blood glucose concentrations exceeding 11mmol/L(200 mg/dL) and ketones in their urine, or blood glucose concentrations exceeding 16.5mmol/L (300mg/dL) regardless of ketone status should postpone exercise and take supplemental insulin. Those with blood glucose level less than 5.5mmol/L (100mg/dL) require a pre exercise carbohydrate snack (e.g. sports drink, juice, glucose tablet, fruit etc.)
Because exercises for diabetics has an insulin-like effect, exercise induced hypoglycemia is the most common problem experienced by exercising diabetics. Hypoglycemia may result when too much insulin is present, or if there is accelerated absorption of insulin from the injection site, which can occur with exercise. Accelerated absorption generally occurs when short-acting insulin is taken and when the injection site is near the active muscles. Hypoglycemia can occur during exercise or up to 4 to 6 hours following an exercise bout. IDDM individuals can reduce the risk of hypoglycemia during acute exercise by taking extra carbohydrates (e.g. glucose sweets) before, and hourly during exercise. IDDM individuals should exercise 1-2 hours after a meal. To avoid the incidence of a hypoglycemic episode it may be necessary to reduce pre-exercise insulin dosages by 30-50%, but this must be carried out under the guidance of a doctor. It is important to monitor blood sugar levels before, during and after exercise.
Patients with Type II diabetes who are managed with diet therapy alone do not usually need to make any adjustments for exercise. Those patients taking oral hypoglycaemic drugs may have their doses on the days of prolonged exercises or miss them altogether depending on their glucose levels. Such patients should also carry some glucose with them and should be able to recognize the symptoms of hypoglycemia.
