Children's scientific exercise methods

The biggest feature of children's physical fitness is their variability and growth and development. Its various indicators are changing rapidly, and the metabolism is characterized by greater assimilation than dissimilation. The various systems of the body are changing rapidly. This change is unbalanced and unified. The nervous system is the first to develop, showing the peak of growth and development. At the age of 7 years, the brain weight increased to 1400 grams, close to the brain weight of adults (1450 grams ) ; the volume of nerve cells increased, the differentiation basically completed; the frontal lobe of the brain grew rapidly, making the children's movement coordination and accuracy develop and improve. The pioneering development of the nervous system laid the foundation for its dominance in various body systems.

The best ways for children to participate in fitness exercises are the following:

( a ) playing table tennis

Playing table tennis can prevent myopia. When playing ping-pong, both eyes must keep a close eye on shuttles, flickered balls, and fast swinging balls to keep the eyeball moving, enhance blood circulation, and improve the function of the oculomotor nerves, thus eliminating or reducing eye fatigue. Play a role in the prevention of myopia.

 

 

( b ) Bounce movement

Exercise is the most brainy, because exercise can promote the vitality of various neural mediators in the brain, making the brain's thinking and reaction more active and agile. At the same time, exercise can improve heart function, speed up blood circulation, and allow the brain to enjoy more oxygen and nutrients. Every oxygen-boosting fitness exercise has a brain-braining effect. In particular, bouncing exercise is better. It can supply the brain with sufficient energy, such as skipping ropes, kicking shuttlecock, jumping rubber bands, and dancing.

 

 

( iii ) "Regional Training"

"Regional training " is very effective in correcting children's " 0 " shape and " X " shaped legs. This has been confirmed by the practice of physical education. The specific approach is: to maintain the body's regular standing posture, and on the mention of Dan Tianqi, legs standing side by side, as straight as possible. " 0 "-shaped legs should be two feet and tight; two knees do their best to rely on, if necessary, can use the elastic rubber band tied on the two knees to increase the internal force. Perform it several times a day, each for more than 20 minutes. It can also vary from person to person, but the duration of each adherence must not be less than 15 minutes.

 

 

( d ) Long-distance running

Long-distance running helps growth and development. Professor Shihe Likuan, a famous physiologist in Japan, once observed the children's long-distance running and observed that after a one- year long-distance running training, the children had normal physical development, and the increase in height and weight was slightly higher than that of ordinary children. In China, there were people who observed the physiological reaction of children running 10,000 meters and found no abnormalities. Therefore, some experts at home and abroad advocate the use of general endurance training as the basis for children's training. Judging from the cardiac function most closely related to long-distance running, the absolute value of children's heart index is lower than that of adults, but the stroke volume per kilogram body weight is not lower than that of adults. It can be seen that the heart of children has a certain load. The ability shows that children's long-distance running training not only does not hinder health, but also helps growth and development.

 

 

( five ) barefoot activities

Barefoot activity enhances the child's constitution. In life, many parents are reluctant to allow children to walk around barefoot. The reason is probably to worry that children will cut their feet, especially for girls. Not only are they afraid of scratching their feet, but they also worry that often barefoot will affect the beauty of their feet. In fact, from a health point of view, it is beneficial to let children play barefoot. Japanese kindergarten, primary and secondary school children often can i see in droves led by the teacher, barefoot, around the playground or jogging organized activities along the corridor. This is the "barefoot training" that has risen more than 20 years ago and is now popular in Japan. Practice has proved that after barefoot training for children for a period of time, the vast majority of children have enhanced physical fitness, height and weight gain, and even colds and colds rarely occur.

The human foot is a moving organ composed of bones, muscles, tendons, blood vessels, nerves, and the like. There are 66 acupuncture points on the six meridians , and there are many nerve reaction points connected to internal organs. Therefore, the traditional Chinese medicine believes that the foot is the root of the human body, the blood circulation of the foot is good and bad, and the brain; the blood in the pelvis The cycle is closely related. Children often barefoot activities, is conducive to promoting systemic blood circulation and metabolism, and regulate autonomic and endocrine function, improve the body's ability to adapt to changes in the outside world, can prevent the nervous system and cardiovascular and cerebrovascular diseases. Barefoot is also very important for the flexibility of the ankle joint. If the ankle joint is stiff or poorly flexible, people tend not only to fatigue but also easily fall when they are active. In the case of walking more, the arch of the foot will become hard and even deformed. Children often move barefoot, but also to meet their children's desire to like barefoot. Most children are active and lively, especially in the hot summer months. The shoes are damp and stuffy. The child’s skin is delicate, and its resistance to bacteria and fungi is poor. Bare feet can reduce corns, ankles, and feet caused by improper footwear. Soft tissue inflammation.
