What are the benefits of physical exercise for primary school students?

I believe that when we were in elementary school, we all knew a phrase that we often heard on campus: "morality, intelligence and physique must be developed comprehensively." Moral, intellectual and physical worthiness refers to moral character, intelligence and physical fitness. So basically we have started physical education classes when we are in primary school and give students physical exercises. So what are the benefits of physical exercise for primary school students? Let me give you a brief introduction below.

1. It can increase height and develop muscles. Physical exercise can enhance the functions of children's various organ systems and make them physically strong. Children are able to grow taller due to the growth of bones throughout the body, especially the growth of long bones, because the epiphyseal cartilage at both ends of the long bones is the growth point of the bones. Physical exercise improves blood circulation and provides more nutrition to bone tissue. At the same time, exercise acts as a mechanical stimulus on bones, thus accelerating bone growth and increasing children's height. Exercise can also exercise children's limbs, increase muscle strength, make muscles gradually become fuller, and make movements more agile.

2. It can promote cardiopulmonary function, accelerate blood circulation and enhance metabolism. During exercise, children's muscle activity consumes a lot of oxygen and discharges more carbon dioxide, so the respiratory organs need to work twice as hard. Over time, the range of chest movement expands, lung capacity increases, and minute ventilation in the lungs increases, which enhances the function of the respiratory organs and has a good effect on preventing common respiratory diseases. It can increase children's gastrointestinal motility, enhance gastrointestinal digestive function, increase appetite, and completely absorb nutrients, allowing children to develop better. Children with anorexia or food refusal need more exercise. Can promote the development of the nervous system.

Through the above introduction, I believe everyone has a clearer understanding of the benefits of physical exercise for primary school students! It can be seen from this that physical exercise is also very important for primary school students who are in the stage of physical development and growth. Today's parents have too high expectations for their children. They usually only focus on their children's academic performance and often ignore their children's physical health.
