In fact, the fastest growth period of children's height is in adolescence. There are many reasons why the height of children is not developed, and there are many factors that are the perfection of various organs. At this time, just pay attention to nutrition and let the children have a good living environment.
(full version)
Whether the height is satisfactory depends on several factors. First, genetic factors, accounting for 70%, and other conditions, including sports, nutrition, environment and social factors. In order to make children grow taller, parents should pay attention to the following points:
First, don't miss the rapid growth period.
During the development of children and adolescents, when is the height the fastest? Studies have confirmed that the height of most Han children in China is about 12 years for girls and 14 years for boys. More than 90% of the girls are between 1 1- 13 years old and the boys are between 13- 15 years old. In order to make children grow taller, parents should pay special attention to their nutrition and exercise during the rapid growth period.
Second, we should pay attention to nutritional supplements.
Nutrition is the key to children's physical growth. The energy, protein and amino acids needed for normal growth of the body must be provided by food, mainly meat, eggs, beans and beans. Bone formation also requires sufficient calcium, phosphorus and trace amounts of manganese and iron. Insufficient calcium intake and vitamin D deficiency will lead to insufficient bone mineralization, vitamin A deficiency will make bones shorter and thicker, and vitamin C deficiency will make bone cells brittle and affect bone growth.
At present, the average family should have a comprehensive and adequate nutrition and a balanced diet. Parents should be careful not to let their children develop the habit of partial eclipse, let alone let their children eat too many snacks, which will affect the intake of important nutrients.
Third, don't neglect physical exercise.
Physical exercise can strengthen the metabolic process of human body, accelerate blood circulation, promote the secretion of growth hormone, accelerate the growth of bone tissue, and be beneficial to human body length. The following kinds of exercises have a certain effect on height growth, so try them.
1.？ The hanging swing adopts horizontal bar or door frame, and the height should be that the body is hung on the bar and the toes can just leave the ground. Hold the lever with both hands, the distance is slightly larger than the shoulder width, the feet are close together, and then the body swings back and forth, not too much, not too long. It is best to arrange exercise every morning and try to relax and droop for 20 seconds. Young men should do 10 ~ 15 times, and young women should do it 2 ~ 6 times.
2.？ When jumping to touch the height, touch the preset object with both hands, which can be branches on the roadside, basketball baskets or ceilings. Jump with your feet and do it 30 times. Take a rest and jump with your left foot and right foot, as above.
3.？ When playing basketball in ball games, actively strive for rebounds and jump shots to break the ball; Try to jump up when playing volleyball, and do more smash and block; Practice jumping up and hitting the ball on the forehead in football.
4.？ Jumping exercises can do one-leg jump, frog jump, triple jump, multi-stage jump and vertical jump in situ.
Fourth, don't forget to create a good living environment for children.
Abnormal mental nervous system will also affect children's physical development. If parents divorce, the relationship between children and guardians is abnormal, children are often abused, or children are seriously stimulated, their growth rate will gradually slow down, making their height lower than the lower limit of normal children of the same age and gender. Being short will aggravate a child's sense of inferiority, which is due to the psychological and social stimulation to the child, which affects the transmission of nerve impulses from the cerebral cortex to the hypothalamus, thus inhibiting the secretion of growth hormone by the pituitary gland. When the child's environment is handled, the growth rate can return to normal.
5. Don't forget to actively prevent and treat chronic diseases.
Children and adolescents should be actively treated for chronic diseases. Chronic infection, chronic hepatitis, chronic nephritis, asthma, heart disease, anemia and other long-term diseases will affect growth and development. Genetic diseases of bones, such as osteochondral dysplasia, can also limit the growth of bones.
