1. Exercise is good for heart and lung health.
The energy consumed during exercise is relatively large, and many of them are provided by aerobic respiration. In the process of exercise, the amount of oxygen transport in the human body increases accordingly. After oxygen enters the lungs, it is transported from the blood to the whole body with the pulse of the heart. In the process of transportation again and again, the strength of myocardium is strengthened, and the pumping function of heart is also enhanced. At the same time, the oxygen absorption function of the lungs is also strengthened, and the level of pulmonary circulation is gradually improved, which is conducive to the strengthening of lung function and lung health.
2. Exercise helps to prevent cardiovascular diseases.
Long-term exercise can increase the content of high-density lipoprotein in blood, effectively slow down the formation of arteriosclerosis, prevent arteriosclerosis, and also have certain preventive and therapeutic effects on cardiovascular diseases such as coronary heart disease. Because exercise can consume excess fat on the wall of blood vessels, make the inner diameter of blood vessels larger, and enhance the elasticity of muscles on the wall of blood vessels, thus enhancing the function of transporting blood and preventing the occurrence of heart disease to some extent. Moreover, exercise also helps to prevent hypertension and diabetes and enhance physical fitness.
3. Exercise can control weight and prevent diseases.
Exercise is beneficial to human muscles to get more exercise, promote the consumption of fat in muscles, thus reducing fat and effectively preventing obesity and a series of diseases caused by obesity, such as hypertension.
4. Exercise is beneficial to enhance human immunity.
Through physical exercise, the functions of various human systems will be strengthened, and the physique will be improved in an all-round way, which is conducive to enhancing human immunity and resistance to diseases, thus effectively protecting health.
5. Exercise can strengthen bones.
Exercise can slow down the loss of calcium in bones, increase the density of bones and reduce the probability of fractures, which is very helpful for improving osteoporosis and preventing fractures. Moreover, for petrochemical workers who have been running around for a long time, more exercise can strengthen their bones and enhance their physique.
6. Exercise can delay aging.
Exercise accelerates the circulation of various systems in the body, thus promoting the elimination of toxic substances in the body and reducing harmful factors, which can not only prevent diseases, but also delay aging.
7. Exercise can improve the function of the nervous system.
Exercise can enhance the activity of cerebral cortex, strengthen its function, keep the nervous system alive, facilitate the secretion of some beneficial hormones, and play a role in maintaining the normalization of body functions. Insisting on exercise can also improve neurasthenia caused by excessive pressure or overwork.
