2. Physical exercise can consume excess calories, reduce weight, avoid excessive conversion of calories into fat, improve patients' lipid metabolism, reduce blood triglyceride and low-density lipoprotein levels, and increase high-density lipoprotein levels, thereby reducing blood lipids, lowering blood lipids, improving fibrinolytic activity of platelets, preventing platelet aggregation and thrombosis, and slowing down the development of atherosclerosis.
3. Moderate physical exercise can reduce neurohumoral response, improve pressure load capacity, reduce vascular tension, improve vascular tension, and help reduce cardiovascular and cerebrovascular diseases such as arteriosclerosis, hypertension, cerebral thrombosis and cerebral hemorrhage.
It can also reduce the occurrence of severe arrhythmia and the probability of sudden death caused by ventricular fibrillation.
4. Exercise can enhance the sensitivity of skeletal muscle cells to insulin, benefit the utilization of glucose, reduce the burden of β cells, correct the disorder of glucose metabolism caused by relative insulin deficiency and insulin resistance, improve glucose and lipid metabolism, and improve the hormone regulation of the body to maintain the stability of blood sugar.
Moderate physical exercise can also help to relieve mental stress, regulate autonomic nerves and restore fatigue, thus avoiding insomnia and neurasthenia common to mental workers.
6. Physical exercise can regulate various organs and immune functions through nerve and endocrine channels, promote the improvement of various system functions of the body, enhance physical fitness and obviously improve resistance, thus achieving the purpose of preventing diseases.
