For people with diabetes, the benefits of exercise are that it increases the body’s sensitivity to glucose when insulin is appropriate, and muscle exercise helps control blood sugar. Although the counter-regulatory hormone increases during exercise, it still increases cardiac output, which increases peripheral tissue blood flow, ultimately increasing the body’s insulin uptake and glucose utilization, and inhibiting hepatic glucose production. Therefore, the counter-regulatory hormones can be finely adjusted to the muscle needs for a short period of exercise, so that the balance of glucose consumption and production can be achieved. However, it is important to note that hypoglycemia should be prevented when exercising for longer periods of time. When insulin is insufficient, the body’s basal blood glucose is high. Under the action of counter-regulatory hormones, exercise can further increase the production of glucose in skeletal muscles and raise blood glucose, which can also induce ketoacidosis, therefore, the effect of exercise on blood glucose must be properly understood. For patients on different insulin regimens, different exercise regimens should be formulated according to the duration of insulin action and the meal pattern of life. Subcutaneous insulin continuous input pump is a microcomputer-controlled automatic drive device, a special syringe is placed in the pump, and a special piping system connects the pump and the subcutaneous needle, which is injected through an ejector needle holder and left under the skin. The insulin pump is fixed with special fixation tape. A meta-analysis study of adults and adolescents using a subcutaneous insulin continuous injection pump (hereafter referred to as insulin pump) showed that it resulted in improved glycemic control, a 1% decrease in blood glucose, a 0.51% decrease in HbA1c (glycosylated hemoglobin), a 14% decrease in insulin use, and a significant reduction in hypoglycemic symptoms. Therefore, more and more children and parents are choosing to use insulin pumps to treat diabetes. However, there are cases of unsatisfactory results of insulin pump treatment, such as increased number of DKA (diabetic ketoacidosis), infections, and hypoglycemic reactions, which are mainly caused by insufficient diabetes education. Patients who use insulin pumps do not learn enough about diabetes and use it flexibly, or the adjuvant therapy is inappropriate. How to exercise for children treated with insulin pumps is an issue of concern for children and parents. In fact, children with insulin pumps have more precise blood glucose control and are closer to normal people, so the exercise program is more casual than for children without insulin pumps. The International Society of Children and Adolescents with Diabetes (ISPAD 2004 Diabetes Guidelines) has the following recommendations: 1. Encourage activity without limiting the type of activity; 2. Measure blood glucose before exercising and then decide which type of exercise to do; 3. Do not exercise when blood glucose is >15.0 mmol/L; 4. Add carbohydrates (such as sugar-free cookies, etc.) when blood glucose is <7.0 mmol/L; 5. Carbohydrates should be carried with you and 15 grams should be eaten every 15 minutes; 6. Purely natural exercises can be carried out, such as water sports, mountain climbing and other exercises; 7.
