Running can delay aging, and bones are the support of the body and the lever of human activities. Teenagers in the growth and development period can improve blood circulation, increase nutrient supply to bone cells, improve the growth ability of bone cells, and thus promote the normal development of bones. The metabolism of the elderly is weakened, muscles are gradually atrophied, bones are degenerated, and bone and joint diseases are increasing. Persisting in running can strengthen metabolism, delay the degenerative changes of bones, prevent the occurrence of bone and joint diseases in the elderly, and thus delay your aging.
Running can protect the heart Running exercise can keep good blood circulation of coronary artery. Long-term running exercise will not narrow the coronary artery due to age, and ensure enough blood supply to the myocardium, thus preventing various heart diseases and maintaining good heart function.
Running can enhance gastrointestinal peristalsis. Running can enhance gastrointestinal peristalsis, increase the secretion of digestive juice, improve digestion and absorption capacity, thereby increasing appetite, supplementing nutrition and strengthening physical fitness.
Running can reduce gynecological diseases and regulate menstruation. For women, running helps to regulate menstruation and reduce gynecological diseases. An American obstetrician and gynecologist investigated the menstrual cycle of 394 female athletes in the 1979 New York Marathon. It was found that 26% of women with menstrual disorder recovered their normal cycle, and 17% of women with amenorrhea recovered their menstruation. This is because running increases metabolism, promotes digestion and absorption, regulates nervous system function and improves endocrine function.
Some young people play ball games and run after catching a cold. After sweating, the symptoms of cold will really be alleviated. This is because when people exercise, the sympathetic nerve is excited, the heartbeat is accelerated, the breathing is accelerated, and the function of the defense system composed of white blood cells and other antibodies in the body is improved. In addition, when sweating, toxins in the body are excreted faster, which relieves cold symptoms. However, this situation only appears in a few people with strong physique and mild symptoms. For most people, especially children, the infirm and the elderly, it is harmful to take part in physical exercise when you have a cold.
[2] Jogging can control weight, prevent arteriosclerosis, regulate the excitement and inhibition of cerebral cortex, and eliminate brain fatigue. Jogging can promote the metabolism of the whole body, improve lipid metabolism and prevent hyperlipidemia in the blood.
In addition, jogging can also increase bone density and prevent osteoporosis. Jogging can improve the normal metabolism of lipid substances in the body, reduce the contents of cholesterol and triglycerides, and prevent and reduce the deposition of cholesterol and other lipids on the blood vessel wall, thus playing a role in preventing and treating senile diseases such as coronary heart disease and hypertension. Jogging can also make the human body produce a low-frequency vibration, which can exercise the smooth muscle of blood vessels, thus increasing the tension of blood vessels, removing the deposits on the blood vessel wall through vibration, and preventing the accumulation of blood lipids on the blood vessel wall, which is of great significance for the prevention and treatment of arteriosclerosis and cardiovascular and cerebrovascular diseases.
Principles and taboos
Cold is an acute upper respiratory disease caused by virus or bacteria. In order to resist the invading virus or bacteria, the human body should mobilize the internal defense system to fight against it. At this time, the body temperature rises, the white blood cells increase, the phagocytosis of cells, the production of antibodies and the detoxification function of the liver are enhanced. At the same time, the metabolism in the body is also accelerated, improving the body's disease resistance. At the same time, people's proper rest is also very important. If you play ball or run after catching a cold, it will further increase the body's heat production and make the metabolism more vigorous, which will inevitably lead to an increase in body temperature, which will lead to abnormal body regulation and excessive excitement of the central nervous system. Excessive consumption of energy substances in the body, including sugar, fat and protein, will weaken the body's resistance.
When a cold is caused by bacteria, the pathogenic bacteria are mostly hemolytic streptococcus and a few are pneumococcus. If you don't rest and treat in time, it may cause sinusitis and bronchitis, rheumatism and nephritis. When a cold is caused by influenza virus, the systemic symptoms are severe. In addition to common cold symptoms, it may further cause serious complications such as pneumonia and even secondary viral myocarditis.
Therefore, for most people, it is not appropriate to take part in physical exercise when they have a cold. They should take medicine and rest under the guidance of a doctor, and it is better to take part in exercise in a few days after the cold is cured.
