Children's bodies are in the period of growth and development, and the heart, an important organ of the cardiovascular system, is not yet mature. Therefore, in physical exercise, high-intensity and strenuous exercise should be controlled for a long time. We should choose sports with flexibility, coordination and speed, such as running, swimming, basketball, table tennis, football, volleyball and other ball games.
Because children's bones and muscles are still growing, the transverse diameter of muscle fibers is not thick enough, and their strength quality is relatively weak, so we should pay attention to mastering the appropriate load, mainly medium and small load.
