First, modern medical research believes that health qigong mainly has the following functions:

Enhance brain function: Experimental research shows that when practicing relaxation and rest, the amplitude of α wave in EEG of practitioners increases and gradually spreads from occipital lobe to temporal lobe.

The oxygen consumption per unit time is obviously decreased, which is about 16% lower than that of normal people in awake state, while the oxygen consumption per unit time of normal people is lower than that in awake state 10%, indicating that health qigong exercise can get better rest than sleep. Because of the alpha wave.

Enhance brain function: Experimental research shows that during relaxation, the amplitude of α wave in the brain of the exerciser increases and gradually spreads from occipital lobe to temporal lobe, and the oxygen consumption per unit time decreases obviously, which is about 65,438+06% lower than that of the normal person in the awake state, while the oxygen consumption per unit time of the normal person in the deep sleep state is 65,438+00% lower than that in the awake state, indicating that health qigong exercise has a better rest than sleep.

Because alpha wave is a wave pattern reflecting cerebral cortex inhibition, the amplitude of A wave increases and tends to spread, which shows that health qigong exercise can reduce or eliminate the bad stimulation of cerebral cortex, regulate the central nervous system, promote the recuperation of cerebral cortex and whole body organs, improve memory ability and develop intelligence.

Regulate the function of each system: Practice has proved that health qigong exercise has a certain effect on preventing and treating hypertension or hypotension, tachycardia or bradycardia, hyperglycemia or hypoglycemia, hyperthyroidism or hypothyroidism, indicating that health qigong exercise has a two-way adjustment effect on various systems of human body.

Promoting blood circulation: Experimental research shows that long-term health qigong exercise can not only enhance the function of the heart, promote the blood flow of large circulation, small circulation and microcirculation, but also reduce the number of abnormal blood vessels, indicating that health qigong has a great influence on the cardiovascular system.

Practice has also proved that after practicing fitness qigong, limbs and body feel very warm, sweating slightly, and the symptoms of soreness are obviously alleviated, indicating that the function of fitness qi promotes blood circulation and has a good effect on preventing and treating cardiovascular and cerebrovascular diseases such as coronary heart disease and cerebral arteriosclerosis and other blood circulation disorders.

Reduce energy consumption: Experimental research shows that practicing kungfu can reduce energy metabolism to varying degrees, and make the human body change from "energy consumption" to "energy storage".

It was found that the ATP content in human blood was significantly higher than that during exercise, with an average increase of 0.54× 10-4M, indicating that practicing internal strength can store energy. Therefore, often practicing the function of bodybuilding qi can reduce energy consumption and increase energy storage, which is beneficial to health care, anti-aging and longevity.

Second, China traditional medical research believes that the role of health qigong is mainly reflected in the following aspects:

Dredge channels and collaterals: Channels and collaterals are the channels through which qi and blood flow. If the meridians are blocked, it will cause pain, and the viscera and organs will not be nourished and warmed by qi and blood, which will lead to various diseases. Fitness qigong exercise can promote the dredging of meridians and relieve or eliminate various diseases. Many comrades feel this way, and many uncomfortable symptoms have improved after practice.

Understanding of Qi

When it comes to qi, people easily think of breathing qi and breathing, so some people translate Qigong into breathing exercise, which is incorrect. Although breathing plays an important role in many schools of qigong, the qi of qigong and the qi of breathing are two different things. From the theoretical height of China's classical culture and traditional Qigong, there are at least the following contents:

(1) natural qi. It is the most basic material form that constitutes the universe and all matter. It is invisible, invisible and intangible to ordinary people, and it is full of the whole universe. "The great is nothing but the small is nothing" (Tube).

It can be directly called Qi or Yuan, and it can also be called Yuan Qi, Daoqi, Extremely Qi, Taiyi ... The ancients believed that invisible Qi is the source of all tangible things and images, in other words, all complicated things that change thousands of times are all manifestations of Qi in disguise.

In the Song Dynasty, Zhang Zai said: "Too empty and invisible, the noumenon of qi; Its gathering is scattered, and the guests who change are shaped. " "On the Yellow Emperor's Internal Classic, Su Wen and Zheng Wuchang" said: "Qi begins with biochemistry, disperses and forms, spreads and breeds, and finally becomes like an image."

In other words, the rise and fall of everything is the result of the change of qi. People are no exception. Zhuangzi pointed out: "When people are born, they gather together. If you gather, you will live, and if you disperse, you will die. " Wang Chong also pointed out: "Water condenses into ice, and gas condenses into human beings".

(2) Qi in human body refers to a special intangible substance that maintains normal life activities. "Huangdi Neijing Lingshu Jueqi" said: "Opening the coke, announcing the taste of five grains, fumigating the skin, nourishing the body and moistening the hair are called qi. If you irrigate with fog and dew. " "Yellow Emperor's Internal Classic Su Wen Angry Days" said: "Yang qi, essence is nourishing the spirit, and softness is nourishing the muscles." Qi is the basis of human life movement.

Zhang Jingyue in Ming Dynasty said, "Human life depends on this qi". There are many discussions about human qi in TCM theory. According to the distribution and function of qi, the names of qi are different, such as true qi, nourishing qi, defending qi, ancestral qi, primordial qi, meridian qi, viscera qi, pre-weather and post-weather.

(3) Interaction and transformation between human qi and natural qi. Qigong theory holds that the process of human life activity is the process of interaction and mutual transformation between human body's own qi and natural qi. If the human body can successfully absorb the gas of nature to "serve" itself, it is a sign of health, otherwise it is illness and death.

Because people are part of the natural qi, practicing Qigong is to strengthen this process. It can be seen that the qi mentioned in Qigong includes both natural qi and human qi. In this regard, "Guanzi Interior Industry" has an incisive exposition:

"The essence of all things (essence, essence of qi-cited by the author), Ben (the ancient collation of the word' Ben' is the mistake of the word' Hua') makes a living, gives birth to grains, is a star, passes between heaven and earth ... hidden in the chest, it is called a saint.

It is people (the ancient collation of the word' people' is the mistake of the word' Ben') who are angry, such as in the sky, in the Yuyuan Garden, in the sea, and at home ... So, when they are angry, they can rely on their strength to be virtuous; Don't call by voice, but say hello by voice (voice is interpreted as' meaning'); Don't lose it. It means becoming a virtue. "

This passage not only expounds the identity of human qi and natural qi, but also points out the cultivation method of absorbing natural qi to achieve temperament transformation, which is different from "I am good at cultivating my noble spirit" in Mencius Gongsun Chou. It is qi, as strong as it is, and it is harmless to raise it directly, so it is stuffed between heaven and earth. Therefore, the meaning of Qigong Qi is very extensive.

Qi, as a specific philosophical category in history, is usually affirmed and named "simple materialism"; As a fuzzy element in the way of human life, people are also willing to accept it.

Harmonizing qi and blood: qi and blood are nutrients of human body. If qi and blood are insufficient, it will lead to anemia or malnutrition, and the immune function will decline, resulting in many deficiency diseases. If qi stagnation and blood stasis occur, it will lead to the disorder of qi and blood operation and produce many solid diseases. Health qigong exercise can not only replenish qi and blood, but also regulate qi and promote blood circulation, and prevent and treat various diseases of deficiency and excess.

Balance Yin and Yang: Many diseases of the human body are caused by the imbalance of Yin and Yang, and a relative balance must be maintained. If the balance of yin and yang is out of balance, it will lead to various diseases such as yin deficiency and hyperactivity of yang, yang deficiency and excess of yin, or yin excess and yang decline. Fitness qigong exercise can balance yin and yang, and can improve and eliminate various diseases of yin and yang imbalance.

Strengthening healthy energy and eliminating evil: Strengthening healthy energy can help healthy qi, and most diseases are related to the deficiency of positive energy and evil reality. The deficiency of positive energy refers to the deficiency of essence and blood, the low function of viscera, and the excess of pathogenic factors refers to the invasion of wind, cold, summer heat, dampness, dryness and fire. Fitness Qigong exercise can not only strengthen the body resistance, but also eliminate evil spirits, so it can prevent and treat various diseases of deficiency and excess.

Third, China qigong research thinks that health qigong has health care function.

Fitness qigong exercise can promote the continuous filling of essence, qi and spirit in the body, and gradually achieve the unity of essence, qi and spirit. Adequate essence will improve the functions of internal organs, tissues and organs, while vigorous spirit will enhance the brain and immune function. Health qigong exercises can strengthen the body without disease, and can be cured and recovered if there is disease, and finally achieve the purpose of health care, anti-aging and anti-aging.

Judging from the practice of participating in health qigong exercise, the main purposes of people participating in health qigong exercise are: strengthening the body, preventing diseases, prolonging life, developing intelligence and cultivating sentiment.

To sum up, the ultimate goal is to achieve health care and anti-aging. Therefore, health qigong is one of people's favorite sports, which has a broad mass base and is paid more and more attention by the state and society.
