How can we achieve and maintain health? It is true that quitting all bad behaviors in life, establishing a reasonable diet and good living habits, and proper physical exercise are the only way to health.
A large number of facts tell us that proper exercise is very effective for maintaining and promoting health. However, excessive exercise is not good for the health, and may also induce some diseases. Here we will tell you the relationship between exercise and health and disease, and how to realize scientific fitness exercise.
Life lies in exercise. The earth is constantly turning, the sun is rising and setting every day, the moon is constantly changing, trees are swaying in the wind, and everything in the world is inseparable from the word "move".
The theory that life lies in movement was put forward by Aristotle, an ancient Greek philosopher, more than 2,300 years ago. At that time, he carved on the cliff: "Do you want to be healthy? Exercise! " This played a positive and effective role in promoting human health at that time and in the long years after. It really reveals the mystery of life.
Philosophers say that "life lies in movement", and there is a folk saying that "people must move", that is to say, "living" means moving, and "moving" means moving. As early as the end of the Eastern Han Dynasty, the famous doctor Hua Tuo said: "If you shake it, the valley qi will disappear and the blood will pass, so you will not get sick." He correctly pointed out that exercise can promote digestion, enhance the function of cardiovascular system and improve the disease resistance of human body. An American sports physiologist even thinks that "lack of exercise is the real chronic suicide, which is as harmful to people as alcohol and nicotine", and even emphasizes the importance of exercise to life.
Exercise is the driving force of life. Exercise can promote cardiovascular function and enhance the reserve capacity of heart pump function.
Research shows that proper exercise can slow down the heart rate, thicken the heart wall and improve the ejection function of the heart. This regulation of the shape and function of cardiovascular system is more suitable for human exercise. Exercise can also prevent and slow down arteriosclerosis. Pathologists have studied thousands of autopsies and found that the incidence of arteriosclerosis in mental workers is 14.5%, while that in manual workers is only 1.3%. Exercise can prevent cholesterol from depositing in blood vessels, dilate arteries and reduce the possibility of blood clots completely blocking arteries.
2. Exercise can improve lung function, promote metabolism, increase vital capacity, help the body deliver more oxygen and eliminate carbon dioxide in time.
3. Exercise can make skeletal muscles stronger, joints more flexible, and shape bodybuilding.
4. Exercise can improve brain function and make the nervous system react sensitively and harmoniously. The brain dominates the limbs, and the activities of the limbs can excite the brain. Regular exercise can improve the effectiveness of the brain and improve the efficiency of memory, thus enhancing memory.
In addition, exercise is a panacea to eliminate anxiety, calm fear and relieve tension. Regular exercise can maintain physical and mental strength, delay aging, prevent diseases and prolong life.
After entering middle age, whenever I have backache, leg pain and stiff neck, I think of the wise saying "Life lies in exercise". After every moderate exercise, the whole body will strongly experience a kind of relaxation and comfort, and the old feelings of tight muscles, "rusty joints" and ineffective legs and feet will never return at this moment. It can be seen that "life lies in sports" is the truth.
However, the development of modern science and technology provides us with many opportunities to be lazy: the developed transportation and communication network has greatly shortened the distance between time and space, and people walk less and less; The appearance of household appliances not only enriches people's lives, but also liberates people from heavy housework, and the opportunities for manual labor are greatly reduced.
According to statistics, from 65438 to the 1920s, 4% of the power used in production and life came from mechanical energy, and 96% came from the muscle strength of people and livestock. But in the 1970s, all kinds of mechanical energy accounted for 99% of the total power, and only 1% of the power came from the muscle strength of people and livestock. It can be seen that with the development of science and technology, human movement is in a state of constant relative decline, and the lack of human movement has become very serious. If you are inactive for a long time, all tissues and organs will degenerate, their functions will decline, and even life will be endangered.
/kloc-At the beginning of the 0/9th century, the famous German doctor Gofirant once pointed out: "No lazy person in the world can live long; Anyone who lives long is active all his life. "
We should remember that a healthy nation must be a nation that loves sports.
Although China's total population is as high as1300 million, according to the definition of sports population given by the State Sports General Administration 1997, people should participate in sports activities at least three times a week, and each activity should last for at least 30 minutes. According to this standard, the statistical report shows that in 2000, the sports population over the age of 16 in China reached 18.3%. Among them, the sports population aged 16-25 is the largest, accounting for 33.4% of the total population, and the sports population aged 26-45 is the least, accounting for less than 15% of the total population. Among people over 45 years old, the number of sports population is increasing. This figure reflects that the number of people participating in physical exercise in China is small and the age groups are concentrated. Young and middle-aged people who need to strengthen exercise most have less people and less time to exercise. This is probably because they have many tasks and heavy family burdens. In fact, none of these can be regarded as reasons for being lazy and not exercising, mainly because of insufficient attention in thought.
Life is precious. Life is like a hundred generations of passers-by, crackling and rushing by. Cherish life, maintain a healthy body, no need for exercise. Life lies in exercise, exercise lies in exercise, exercise lies in persistence, and persistence is victory.
