Why is physical exercise essential for the healthy development of children and adolescents?

Childhood obesity and the decline in cardiovascular system function are significant factors contributing to chronic diseases like diabetes and coronary heart disease in adulthood. Engaging in scientific physical exercise plays a crucial role in preventing these chronic conditions.

1. During physical exercise, the muscles and bones of children and adolescents receive external stimulation, promoting their muscular and skeletal development.

2. Long-term and scientifically conducted physical exercise can increase the chest circumference and the strength of respiratory muscles in children and adolescents, thereby improving lung capacity and enhancing cardiovascular function.

3. Physical exercise promotes the development of the nervous system. If an individual lacks physical exercise during childhood and adolescence, their coordination ability in adulthood may be compromised.

4. Physical exercise can alleviate eye fatigue, slow down the progression of myopia, and protect vision. During the exercise process, the ciliary muscles constantly contract and relax, increasing blood circulation in the eyes, thus providing more nutrients. Moreover, under strong outdoor light, the pupils of children and adolescents constrict, increasing depth of field and reducing blur, which effectively suppresses the occurrence of myopia.

5. Physical exercise helps alleviate anxiety and tension, reducing or even eliminating negative emotions, thereby enhancing the mental well-being of children and adolescents. Participating in physical exercise also helps them develop a rational approach to setbacks and cultivate a proper outlook on life.

6. Physical exercise serves as an important social platform for children and adolescents. Engaging in sports with peers helps them build positive interpersonal relationships.
