First, exercise contributes to the growth of height.
Whether boys or girls, tall figure is always enviable. In order to make their children grow taller, parents first think of nutrition, such as calcium supplementation. Actually, exercise is also very important.
Height is closely related to the length of body bones, and the growth of bones depends on the intensity stimulation of exercise on bone formation. Muscle contraction and gravity changes in exercise send signals to bone tissue, making it feel the need for growth. The stronger this signal is, the greater the growth reaction of bones, so children who exercise regularly can grow taller.
Second, sports cultivate team spirit.
Only children are relatively short of friends of the same age, especially in the relatively closed living environment of modern society. The only child matures relatively late, has poor social adaptability, is not good at interacting with people, and even needs parents to come forward to find friends.
Taking part in sports can help overcome these unfavorable factors in the process of children's growth to some extent. Unlike most extra-curricular cram schools, children still study separately in class. The playfulness of sports makes children more relaxed and open-minded, and it is easier to get closer when contacting friends of the same age.
Thirdly, exercise improves learning efficiency.
Letting children play 1 hour on the playground every day is not so much a delay in learning as a delay in book learning for more than one day1hour. More importantly, after a period of intense book study, it is often difficult for the brain to relax. Activating different areas of the brain through physical activities can change this situation and better rest the areas of the brain related to book learning.
Fourth, exercise helps to develop lifelong exercise habits.
The study in the student days lays the foundation for the lifelong career and paves the way for the lifelong health. Life lies in exercise, and it lies in persisting in exercise from childhood to adulthood. Facts have proved that people who carry out systematic physical exercise since childhood are more likely to keep the habit of lifelong physical exercise. People can't achieve anything until middle age, and the health risks accumulated by bad living habits often appear at this time. When the illness prevents people from harvesting achievements in the first half of their lives, regret and regret will be of no help.
5. Exercise can prevent uneven development.
In the wrong education in China in the past, most students could not speak physical education class. Our country only pays attention to the cultivation of students' Chinese, mathematics and English, and has cultivated many geniuses in study and fools in life.
In recent years, great changes have taken place in education in China, and most people have only studied in the past. For the balanced development in many aspects, some students can't integrate into society, and they will feel ignorant when they leave school. This development is unbalanced and should be stopped.
