Scientific research has proven that primary school students who insist on taking physical education classes and actively engage in physical exercise can strengthen their bones, promote growth and development, and make children grow rapidly in height.
Because during physical exercise, the pulling and gravity effects of muscles on bones are not only beneficial to improving the shape and function of bones, making bones thicker and stronger, but also beneficial to the spine, thorax, pelvis, The correct formation of bones such as the arch of the foot will also improve the mechanical properties of the bones.
However, unscientific exercise will also have adverse effects on bones. Therefore, physical education teachers must guide students to exercise according to scientific methods.
2. The impact of physical exercise on joints:
Through the study and exercise of physical education classes, joint capsules, ligaments and tendons can be thickened and stretched, and the joints around the joints can be stretched. Muscle strength and elasticity are increased, which will increase the range of joint movement and make the joints flexible and firm. For example, the excellent flexibility of gymnasts and acrobats fully illustrates the amazing role of physical exercise.

Primary school physical education:
The physical education of primary school students is education aimed at physical and psychological physical exercise of primary school students. Use practical means to cultivate physical education and health knowledge for primary school students! While ensuring the healthy growth of students, appropriate scientific exercises are provided.
It mainly focuses on games to cultivate interests, and the teaching method combines students’ independent exercise and habit development! I personally think that primary school students should not do excessive training, especially upper limb training. Therefore, swimming lessons are not suitable for students below the fourth grade of primary school! Give students more adequate sleep and scientific exercise, just control the time to 20 minutes!
Physical exercise:
It refers to people making self-selection according to their physical needs, using various physical means, and combining natural forces and health measures to develop the body, improve health, and enhance physical fitness. Sports activities for the purpose of regulating the spirit, enriching cultural life and controlling leisure time.
Physical exercise is a process of physical activity that uses various physical means, combined with natural forces (sunlight, air, water) and sanitary measures, to develop the body, improve health, enhance physical fitness, and entertain the body and mind. It is the main form of mass sports activities. It plays an important role in promoting the growth and development of the human body, cultivating a healthy body, improving the body's working ability, and even improving the physique of the entire nation.
It is characterized by a wide range of people. People of all ages, genders, different occupations and health conditions can perform appropriate exercises according to their personal conditions. The form and content are flexible and diverse, and can be practiced individually or in a group. The content of exercise is extremely rich and can be divided into five categories: fitness exercise, bodybuilding exercise, entertainment sports, combat sports, medical and corrective sports.
There are various exercise methods. In addition to the commonly used exercises in teaching and training, people have also formed various eclectic fitness methods through long-term exercise practice. The determination of exercise content and methods and the entire exercise process should follow the principle of physical exercise, that is, targeted. If traditional Chinese exercise methods such as the combination of form and spirit, the combination of movement and stillness, and the combination of internal and external can be used at the same time, the results will be greater.

The purpose of physical exercise
Exercise has no utility and no vanity. The purpose of exercise is for health. The purpose is to be happy.
Most of the school’s physical education classes are track and field events, such as running, long jump, high jump, tennis, basketball, football, table tennis and other interesting ball games. Most of them are for children to entertain themselves. Independent participation in music, let alone the spread of sports culture. This has caused a bigger misguidance. Children's current sports culture is mostly affected by mainstream media, manufacturer advertising, and family environment. For example, the Yao Ming phenomenon. How many children hope that they can grow as tall as Yao Ming and play basketball. There is a difference on the field, but parents have a wrong understanding. Height-increasing shoes and height-increasing drugs are everywhere on TV. Height has become a fashion and standard. If every centimeter of height increase shortens life span by 10 years, would anyone be willing to make such a deal? But our parents are willing? People's quality of life is not based on height as the only criterion. Everything should be allowed to take its course, and do not let parents' ignorance ruin their children. A child’s future is not limited to playing basketball. How to live a healthier body, a happier life, a longer life, and a happier mood are the ultimate goals we are pursuing now.
We have done too little work in physical education, and we have done even less work in girls’ sports. From the very beginning, there were no women’s events in the Olympic Games. Sports are all men’s patents. Now , we have not yet realized the seriousness of this problem. Maybe in competitive sports in our country, the yin wins and the yang declines. But look at how much hard work these require. Parents are also willing to let their young daughters suffer. Strict professional physical training. Girls have no choice. Most of them fight for honor to fulfill the mission of their parents, teachers, and country. How tragic. Can you really understand this at such a young age?
Sports should return to the true meaning of sports. The original purpose of the Olympic Games was to show the strength and beauty of human beings. Business and competition are not all of sports. We should give children more correct sports culture spread.
Let us exercise together and grow up healthily and happily in exercise. Appropriate competition, appropriate utilitarianism, appropriate vanity, enough is enough, and excess is not enough.

Especially with the development of social economy, people's living standards have been improved, and people's spiritual needs are higher than their material needs. People's understanding of sports is not limited to physical fitness. People hope to get more spiritual enjoyment through participation in sports activities. For example, people watch sports competitions, beautiful sports movements, exciting competitions, etc., which give people beautiful enjoyment. Also at the competition site, as the competition progresses, people can shout loudly and vent their emotions to their heart's content. People feel a sense of spiritual ease. A successful shot, a beautiful shot, aerobics with fast-paced music, etc. are not just about fitness, but more importantly, they give people a sense of mental and neurological release, a sense of joy, a sense of accomplishment, and a boost in mood. Feeling of comfort. These are the spiritual values ??that sports bring to people. The higher the living standard, the more people pay attention to the value of sportsmanship.
In addition, sports can also help cultivate people's brave and tenacious character, the quality of self-transcendence, the will to meet challenges and the ability to take risks, and help cultivate people's sense of competition and collaboration
