What Is the Connection Between Exercise and Insulin Sensitivity?

Insulin is a protein hormone secreted by islet cells stimulated by endogenous or exogenous substances such as glucose, lactose, ribose, arginine, glucagon and the like. Insulin is the only hormone in the body that lowers blood sugar and promotes glycogen, fat, and protein synthesis.

Insulin resistance (IR) refers to a decrease in the sensitivity of the target organ to the action of insulin, that is, a state in which a normal dose of insulin produces a lower than normal biological effect. At present, it is believed that IR is not only the basis of the onset of type 2 diabetes, but also the main line that runs through a variety of metabolic-related diseases.

The cause of insulin resistance is not fully understood. It is generally believed that there is a problem with the insulin receiver in the human body, so if the insulin receiver is not completely repaired and the insulin secretion is simply stimulated, the insulin resistance cannot be fundamentally treated.

Insulin sensitivity describes the degree of insulin resistance. The lower the insulin sensitivity, the worse the effect of unit insulin, and the lower the degree of carbohydrate breakdown. Type 2 diabetes is caused by low insulin secretion and low insulin sensitivity. With sufficient secretion, improving insulin sensitivity is a good way to treat diabetes.

Improving insulin sensitivity is a new idea in the research of hypoglycemic drugs. Because more people with type 2 diabetes have reduced insulin sensitivity, that is, insulin resistance, so that insulin can not perform its normal physiological function, so that blood sugar remains high, and hyperglycemia continues to stimulate insulin secretion, resulting in hyperinsulinism. It can cause a series of changes such as high blood pressure, high blood sugar, high blood viscosity, high weight, and cardiovascular and cerebrovascular diseases.
