First of all, lack of exercise reduces the metabolic function of the human body. The possibility of obesity, diabetes, hypertension, stroke and heart disease is five to eight times higher than that of people who insist on reasonable exercise. Premature cardiac failure should be more than ten years; The incidence of arteriosclerosis, nephropathy, gallstones, osteoporosis, cancer and mental depression has also increased significantly.

A medical study shows that people who live and work in a sedentary posture all the year round have a significantly higher mortality rate than those who insist on exercise; Keeping the body relatively still is harmful to health, which is equivalent to smoking a pack of cigarettes every day.

As a wise modern man, if he realizes that he lacks the corresponding amount of exercise, he should add a task to himself-spare 30 to 60 minutes for exercise that suits him every day.

If a person wants to live and work healthily and energetically, delay aging, prolong life and fully enjoy life, then he should add the task of exercise to his daily life.

How to exercise more healthily?

Drinking a small glass of water before and after exercise is beneficial to replenish the energy of exercise.

Exercise should be based on personal physique. For example, if endurance is not strong, you can choose strength sports, and if flexibility is not strong, you can choose gymnastics.

Exercise should be moderate, moderate and not excessive. Excessive exercise will do harm to your health.

Try to choose a special sports venue to exercise, and don't exercise on the road.

The choice of exercise time is usually better in the morning. If it is foggy in the morning, it is not suitable for exercise.

In daily activities, brisk walking can be regarded as moderate exercise. Others, such as riding a bicycle to pick up and drop off children, going down the stairs on the fifth floor every day, will not cause rapid heartbeat, sweating and muscle contraction, which is not a moderate activity.

Nowadays, the pace of people's life is accelerating, and few people can do moderate activities for more than 150 minutes per week. Moderate exercise is a little asthma, but you can talk, but you can't sing. Your breathing and heartbeat will be faster than usual, and you will sweat and feel a little tired. If the maximum force is 20 minutes, moderate exercise can be controlled at 1 1 to 13. We can do some things that we usually do, such as washing clothes, mopping the floor, washing the car, walking with heavy objects, getting off early, not taking the elevator and so on.

In sports, you can walk, ride a bike, fight boxing and play ball. If you walk, the speed should be greater than 4.8 kilometers per hour to be considered moderate exercise.

Aerobic exercise is particularly important for our heart protection. It is best to keep exercising for three to five days a week and keep the habit of stretching every day, such as morning exercise. In daily life, drive less, take more cars, walk more, and don't take the bus. In the long run, you will have good health and posture.

The importance of sports

As we all know, physical exercise can bring you health, not only physically, but also physically and psychologically.

Through this semester's physical education study, I further realized the importance of physical exercise.

The health benefits can be summarized as follows:

1, preventing cardiovascular diseases

2. Improve the function of respiratory system

3. Improve the function of digestive system.

4. Improve the function of nervous system.

5. Reduce the risk of diabetes.

Step 6 prevent fractures

7. Ability to maintain physical activity

8. Weight control and body shape change

9. Relieve psychological stress

10, prolong life.

The effects on mental health are: improving emotional state; Improve intellectual function; Determine a good self-concept; Cultivate strong will quality; Eliminate fatigue; Treat mental illness. Science and practice have proved that improving health and physique involves many factors, and physical exercise is the most extreme and effective means. In modern society, due to the development of science and technology, the level of human labor productivity is high, the physical activity of modern people is decreasing day by day, and the incidence of "modern civilization diseases" such as obesity and cardiovascular diseases is increasing. Physical exercise is a good way to treat the diseases of modern civilization. Internationally, especially in some economically developed countries and regions, the concept of strengthening the body, improving the national physique and improving the quality of life through physical exercise has long been deeply rooted in the hearts of the people. Most people regard daily physical exercise as an indispensable part of their lives.

Among them, running is a good exercise. Don't jog fast while running, gradually increase the time. When running, you breathe deeply and long. Generally, the nose and mouth are used for breathing, and the mouth and mouth can be used for serious physical decline. Jogging, as a healthy aerobic exercise, should be distinguished from running fast. Generally speaking, the most suitable number of heart rate rhythms for physical exercise is (220- age) ×60%. When you run, you can measure the following items properly. If you have a heart rate meter, look at it. If not, it is estimated that insisting on running will make the heart and cardiovascular system function stronger. When the maximum oxygen uptake increases, the oxygen delivered to various organs of the body increases greatly, and the working quality of various organs naturally improves greatly. In addition, middle and long-distance running will accelerate blood circulation, so that the coronary artery has enough blood to supply the myocardium, thus preventing various heart diseases. Through the movement of lower limbs, it can promote venous blood to return to the heart and prevent venous thrombosis.
