Benefits of throwing sandbags
1, increase the height
Throwing sandbags is a kind of sports game, which can enhance the functions of various organs and systems of children's bodies and make them strong. Children can grow tall because of the growth of the whole bone, especially the long bone, because the epiphyseal cartilage at both ends of the long bone is the growth point of the bone.
As a result of physical exercise, blood circulation is improved and bone tissue gets more nutrition. At the same time, exercise has a mechanical stimulation effect on bones. Therefore, it can accelerate the growth of bones and increase the height of children. Infant swimming is widely carried out in the former Soviet Union, Germany and other countries. Studies by physiological and medical experts in those places show that babies can grow faster than ordinary children when they participate in swimming.
2, increase the sensitivity and strength
The running and jumping of throwing sandbags can strengthen the observation of eyes. Throwing sandbags can enhance the muscle strength of the upper limbs, and running can enhance the muscle strength of the lower limbs, that is, exercising the child's body, which is equivalent to some conditioned reflex training for the child, so that the child can establish contact in the brain center through these tactile stimuli and muscle training, which can make the child's movements sensitive and muscular.
3. Enhance cardiopulmonary function
In the process of throwing sandbags, children's muscle activities need to consume a lot of oxygen and discharge more carbon dioxide, so the respiratory organs need to work twice. Over time, the range of chest activities is expanded, the vital capacity is improved, and the ventilation per minute (that is, the ventilation per minute) of the lungs is increased, which enhances the function of respiratory organs and has a good effect on preventing common respiratory diseases.
4. Improve gastrointestinal function
Throwing sandbags can increase children's gastrointestinal peristalsis, enhance gastrointestinal digestion, increase appetite, completely absorb nutrients, and make children develop better. Children who are anorexic and refuse to eat need more exercise.
