Physical exercise is not only one of the most basic treatments for obesity and type 2 diabetes, but also for 1 diabetes.

The main function of sugar in life activities is to provide energy and carbon source, and 50%-70% of the energy needed by human body comes from sugar. There are three sources of blood sugar: the first is the sugar in the food digested and absorbed by the gastrointestinal tract, and the second is the decomposition of liver glycogen. The third way: liver gluconeogenesis. Blood sugar in blood must enter cells to be used by tissues, while blood sugar needs insulin to enter cells, and it must pass through insulin receptors when entering cells. Insulin has decreased or the door of insulin receptor has not been opened. Blood sugar can't enter cells and stay in the blood.

Under the regulation of insulin, glucagon, glucocorticoid, adrenaline and other hormones, the blood sugar level of normal people is quite constant, maintaining between 3.89-6.11mmol/L.

Insulin is the only hormone in the body that lowers blood sugar. 1 type diabetes is due to the absolute deficiency of insulin secretion, which leads to the increase of blood sugar. Type 2 sugar is caused by insulin deficiency or insulin resistance.

Most of the carbohydrates in the food we eat are converted into fat and stored in adipose tissue, and a small part is stored in the form of glycogen. Glycogen mainly includes liver glycogen and muscle glycogen. When the body needs sugar, glycogen can be quickly utilized and decomposed to produce glucose for emergency use. However, muscle glycogen mainly provides energy for muscle contraction and cannot be converted into blood sugar.

Physical exercise is a process in which the human body consumes energy. In this process, not only the insulin receptor is opened more, but also the body is stimulated to secrete more insulin, and the sensitivity of insulin will also increase. Muscle glycogen consumption increases during exercise, and blood sugar enters muscle cells to synthesize muscle glycogen for supplementation. Therefore, after 2-3 hours of moderate intensity exercise, blood sugar will drop significantly. This hypoglycemic effect can last for several hours.

So what kind of exercise is better for diabetics to control blood sugar?

You can do any sport, such as running, skipping, swimming, playing ball, dancing, Tai Ji Chuan, gymnastics and so on. As long as you like, the premise is that you do all kinds of preventive work in advance.
