(a) Significantly increase the height of children.

Children's physical education can enhance the functions of various organ 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) Let the child's muscles gradually plump.

Can exercise children's limbs, increase muscle strength, so that muscles gradually plump up. If we strengthen the support of abdominal muscles, psoas muscles, back muscles and limbs, strengthen the exercise of lower limb muscle strength, and carry out some conditioned reflex training before the child's movements develop, so that the child can establish contact in the brain center through these tactile stimuli and muscle training, and the child's movements can become sensitive and muscles can become developed.

(3) Make the child's cardiopulmonary function good.

Exercise can promote cardiopulmonary function, accelerate blood circulation, strengthen metabolism, develop myocardium and enhance contractility. During exercise, children's muscle activities need to consume a lot of oxygen and discharge more carbon dioxide, so the respiratory organs need to work harder. 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) Enhance children's gastrointestinal ability.

Exercise can make children's gastrointestinal peristalsis increase, gastrointestinal digestion ability increase, appetite increase, nutrition absorption is complete, and children develop better. Children who are anorexic and refuse to eat need more exercise.

(5) Make the child's nervous system normal.

Can promote the development of the nervous system. During exercise, the coordinated movement of all parts of the body is carried out under the unified control and regulation of the nervous system. Therefore, while doing physical exercise, the nervous system itself is also exercising and improving. Such as all kinds of gymnastics, can make the baby from disorderly movements, gradually form and develop into differentiated, purposeful and coordinated movements, which is a good adjustment to the nervous system.

(6) Improve children's physical fitness.

It can prevent diseases. Children do more outdoor sports, bathe in sunshine, air and water, and gradually can withstand the stimulation of external environmental changes. The mucous membranes of the skin and respiratory tract are constantly exercised, which enhances their tolerance, and the cerebral cortex also forms a conditioned reflex to the stimulation of cold and heat. When natural factors change, children can respond quickly and accurately, so as to keep the body in balance with the external environment, so that it is not easy to catch a cold or suffer from heatstroke.

Extension: a sport suitable for children

There are many sports suitable for children, such as skipping rope, swimming, gymnastics, martial arts, running, kicking shuttlecock, skateboarding, roller skating, ball games (football, basketball, badminton, table tennis, tennis), and more suitable for girls' dancing, yoga, aerobics, bungee jumping and so on. And all kinds of sports have their unique benefits:

(1) jump rope

Jumping rope can strengthen the brain. Skipping rope can promote blood circulation, make people feel comfortable and walk effectively. More importantly, it can play a role in dredging meridians and strengthening the brain.

(2) Swimming

Swimming is also a good exercise for children. Swimming can increase vital capacity, improve the body's adaptability to the external environment and enhance its resistance to diseases.

③ Gymnastics

Gymnastics also increases the flexibility of children's bodies.

Children's golf

The greatest value of children's golf is not to let them hit the ball blindly and exercise their nonexistent muscles, but to let them exercise the coordination of hands, eyes and waist in a standard swing, thus promoting the rapid development of the nervous system.

(5) Children's tennis

Children's tennis (badminton, table tennis) is essentially different from adult tennis. Children play tennis with sponge balls, which are extremely light in weight. Children's tennis has a strong training effect on children's reaction ability, balance ability and attention. The most prominent thing is that children can strengthen their spatial judgment ability and hand-brain coordination ability in the happy return.

(6) Children's bicycles

Riding a bike can improve the sensitivity of reaction. Cycling regularly can develop the muscle strength of children's legs and feet, and improve children's movement speed, reaction sensitivity and balance ability. Three-year-old children can prepare a tricycle, with a low center of gravity and not easy to fall, and children will soon master the essentials of cycling. Children find that they can master a new technology quickly, which will increase their self-confidence.

(7) Children's football

Football is the most balanced sport in all ball games, and all parts of the human body can get full exercise and exercise. Children can improve their strength, speed, endurance and balance in football, and can exercise their sensitivity and coordination, which is very beneficial to the development of their nervous system. At the same time, football is a team sport, and children can get the initial team consciousness in football matches. More importantly, football is a very interesting sport, and it is easier for children to keep exercising for a long time.

Special reminder: First of all, children are forbidden to use header to protect head safety and brain development; Secondly, it is forbidden to tackle the ball to avoid serious injuries such as fractures caused by shovel injuries; Before exercise, children must be taught to protect themselves with their hands in the game and refuse to play hardball.

(8) Wushu

It is understood that the National Wushu Association has specially created four sets of Wushu routines that are most suitable for children. Through scientific Wushu routine practice, you can increase bone density, enhance the stability and flexibility of joints, and improve muscle elasticity and body flexibility; At the same time, Wushu has no age taboo, and practicing from childhood can effectively shape the masculinity of children "sitting like a bell, standing like a pine, lying like a bow and walking like the wind".

(9) Skating

Children can train and improve their balance ability by practicing skating, because children are in the development period of vestibule and semicircular canal. Swallow-like balance and rotation in skating are good postures to improve balance ability, and skating can also increase children's cardiopulmonary function and flexibility.

(10) mountain climbing

Mountain climbing can exercise children's perseverance, broaden their horizons and form an open-minded and optimistic character.

The right brain's perception of images and stimulation of cells in motion are faster and stronger than those in static state. For example, jump for half an hour every day, play table tennis, badminton and so on. And consciously let the left hand repeat several actions when boxing or doing exercises to stimulate the right brain.
