Health is an important factor for human survival and development. It belongs to individuals and more to society. Health and longevity are the best wishes of mankind for thousands of years. But the existence of health needs scientific exercise, and only through scientific exercise can health be accompanied for a long time. Therefore, it is of great significance to cultivate a lifestyle that adheres to scientific exercise and reasonable physical exercise for strengthening physical fitness and improving health.
First, physical exercise can make people develop healthily.
1, promoting the healthy development of human body.
The growth and development of bones need constant absorption of nutrients. Physical exercise can promote blood circulation and increase blood supply to bones. At the same time, various movements in physical exercise also have a good stimulating effect on bone growth. Through scientific physical exercise, muscle volume will increase, muscle fat will decrease and muscle capillaries will increase. Make your body look plump and firm.
2. It can give full play to human functions. Proper physical exercise is of great significance for maintaining and enhancing human activity ability. People who have been engaged in physical exercise for a long time can enhance their physical fitness and prolong their life.
According to domestic sports science research, physical exercise can improve motor function and the function of heart and circulatory system. Foreign scientists have also done an experiment to make healthy young people stay in bed for 9 days. It was found that their working ability of cardiac circulatory system, respiratory system and metabolism decreased by 265,438 0% on average, and their cardiac volume decreased by 65,438 00%.
Second, physical exercise can promote people's mental health development.
1, cultivate good will quality
Physical exercise, whether organized or individual, has a positive effect on the cultivation and exercise of good consciousness. Persisting in regular exercise requires consciousness and self-control. Anyone who has been engaged in physical exercise for a long time knows that it is impossible to persist for a long time without perseverance and perseverance to overcome difficulties. In physical exercise, you need to complete a certain amount of physical exercise and bear a certain amount of exercise load. Without consciousness, persistence and determination, it is impossible.
2. Adjust people's mood and improve people's spirit.
Good mood mainly refers to the stability and balance of the whole psychological state, which is conducive to maintaining and promoting the stability of the whole body. Engaged in physical exercise, you can adjust your emotions, and under the control of the central nervous system, adjust and balance all aspects of the internal relations of the body accordingly, which will also have a good effect on your emotions and spirits, especially for people who like sports.
Third, physical exercise can improve people's ability to adapt to society.
1, improve the human body's ability to adapt to the environment.
People who have the basis of physical exercise have strong adaptability to the external environment. There are two basic reasons: First, long-term physical exercise improves their health and physical fitness, and the ability of various tissues and systems of the body to withstand external stimuli and coordinate with each other is enhanced under the control of the central nervous system; The second is to take part in physical exercise regularly.
It is carried out in various external environments and conditions, so that the body can be exercised and the adaptability can be continuously improved.
2. Promote social exchanges and friendship.
Physical exercise is a social activity. In the process of physical exercise, people can not only exercise, but also promote social communication and friendship in various exercise activities. So? Healthy? Is the ultimate goal of sports. Put it into college physical education teaching? Health first? The guiding ideology establishes the consciousness and habit of cultivating students' lifelong exercise, thus cultivating college students? Moral, intellectual and physical? The purpose of all-round development.
Fourth, according to your own fitness plan.
For the sake of self-health, for a young man in the golden age of his life, health seems to have a far-reaching impact on his later life. Everyone knows that without a healthy body, life will not be enjoyed no matter how rich it is. So making a good fitness plan is of great significance to me. At my age, people are in the heyday of physical function, and their heart rate, vital capacity, sensitivity, stability and flexibility of bones have reached the best point. From the point of view of sports medicine, insufficient exercise during this period is more harmful to the body than large exercise. Like me, you can do any intensity exercise, and your heart can increase blood transfusion through endurance exercise. In short, I try my best to reserve resources for my future health and exercise.
First of all, exercise can be done every other day on Monday, Wednesday and Friday for about 30 minutes each time. The way is to try lifting weights, such as dumbbells. The load is 60% of the ultimate muscle strength. I should be able to lift the weight between 10kg and 15kg, and repeat the exercise until my muscles feel tired (about 10-65 each time). If I don't feel tired after practicing for many times, I can increase the weight of 10%, and I must exercise the main muscle groups (chest muscle, shoulder muscle and back muscle)
Then, what you need to do is 20 minutes of cardiovascular exercise, such as jogging, swimming, cycling and so on. , the strength is 150- 170 times/min. This will help to increase vital capacity and blood circulation.
Finally, we must carry out brain-strengthening exercise, because brain-strengthening is also a way of fitness. Sometimes I often feel dizzy after getting up in the morning. I know this is mainly caused by insufficient blood supply to the brain. So I thought of a set of brain exercises, which is very effective in relieving dizziness. Brain exercises are roughly as follows:
1. Shrugging up and down: Stand with your feet apart, about shoulder width, lift your shoulders as far as possible, make your head stick between your shoulders, pause for a moment, and your shoulders suddenly droop. Do it for eight times.
Second, the back arm lifting action: the two arms are crossed and straightened behind the back, and then lifted hard, like pushing the top of the head with the shoulder blade. Two or three seconds later, both arms suddenly fall, like hitting the waist (in fact, you can also hit it), and do it again.
Third, the fork hand stretches forward: bend the elbow, cross your fingers on your chest, stretch your hands forward quickly, and bow your head forward quickly so that your head is sandwiched between two straight forearms for five to ten times.
Fourth, the fork hand turns the shoulder action: the five fingers are crossed on the chest, the palms are down, and the shoulders are turned as far as possible. The head must be turned back, paying attention to maintaining the initial posture, and the rotation range should be equal to or greater than 90 degrees. Alternate left and right, do it five to ten times.
5. Forward and backward shoulder bending action: First, bend the shoulder backwards as far as possible, as if the two shoulder blades are going to touch. Then bend your shoulders forward as if they were close to your chest, put your hands together and repeat five or ten times.
Six, the front and back shoulder movement: elbow flexion, at right angles, rotating shoulders, from front to back, and then from back to front, the number of rotations is not limited.
I believe that as long as I persist, I will gain a lot. Starting today, I will start my own fitness program, because only in this way can I learn what I can't learn in class. Thanks to the teacher's careful guidance for a semester, because you gave me a fairly complete fitness plan.

Science and technology sports, health, physical exercise
Health, longevity and wisdom are the good wishes of human beings. Since ancient times thousands of years ago, people have been exploring the mystery of preventing diseases and prolonging life. Ancient Greek famous saying:? If you want to be strong, run! If you want to stay healthy, run! If you want to be smart, run! ? Clearly put forward the importance of running to human health. In the era of rapid development of modern society, people are more aware of the value of life, attach importance to the pursuit of quality of life, and the status and value of health are also improving.
Physical exercise can improve the intelligence level, and a normal intelligence level is the most basic psychological condition for people to engage in various activities. Physical exercise activates the right brain intentionally or unintentionally, strengthens the thinking function in images and develops intelligence. It can be seen that physical education teaching is closely related to the intellectual development of the right brain. Physical education teaching is an effective means and way to develop the intelligence of participants.
Establish a good self-concept. Self-concept refers to students' comprehensive evaluation of their physical condition, psychological characteristics and emotions. Is composed of many self-feelings and evaluations, including? Self-positioning? 、? Physical skills? 、? Physical and natural conditions? 、? My hobby orientation? Wait a minute. As we all know, physical exercise can make people strong and energetic, so it is very important to insist on physical exercise to improve students' physical form and psychological quality. Because physical appearance and psychological quality are closely related to the evaluation of students' self-concept, whether they are tall or short, fat or thin, male or female, their individual dissatisfaction with themselves will affect their self-esteem, make them depressed, and then produce an uneasy psychological state and the incidence of depression. Some researchers have found that muscle strength level is positively related to individual psychological and emotional stability and self-confidence. At the same time, it is found that strengthening strength training through continuous scientific physical exercise will improve students' self-confidence and psychological endurance, thus significantly improving individual self-concept.
The World Health Organization recognizes that health is a basic human right. Modern scientific research reveals that aerobic endurance is the most beneficial to people's health among all sports. According to foreign data, the amount of oxygen inhaled by human body in exercise is 8 times that in quiet state, which means that aerobic metabolic exercise (endurance exercise) can make human body get the best oxygen intake. Aerobic exercises recommended by scholars all over the world are brisk walking, jogging, swimming, cycling and aerobic exercise (dancing). These exercises can effectively enhance the ability of respiratory system to absorb oxygen, cardiovascular system load and transport oxygen, and organize the ability of aerobic metabolism and utilization of oxygen, so aerobic exercise has good physiological, biochemical and psychological effects on human body.
The metabolism of aerobic exercise mainly depends on aerobic metabolism, that is, the process that sugar, fat and protein are oxidized into carbon dioxide and water under aerobic conditions. The metabolic process releases energy to synthesize ATP, which constitutes the energy supply system of skeletal muscle aerobic metabolism. Bran, fat and protein are called cell fuels. Among them, sugar is an important part of human tissues and cells, accounting for as much as 70% of human energy sources, and exists in the form of glycogen. When aerobic exercise, muscle glycogen is consumed first, blood sugar is supplemented when muscle glycogen is insufficient, and liver glycogen continues to supplement blood sugar. Long-term exercise can improve the blood flow distribution during exercise, increase the liver blood flow, increase the quality of gluconeogenic free radicals flowing through the liver, and correspondingly increase the probability of being metabolized.
