3.Is there a way to make children grow into "long legs"?
The study found that the body proportion showed a growth pattern of "first declining and then slightly rising, and basically stable after the age of 17". To put it simply, the growth rate of the lower limbs before puberty is faster than that of the upper body, and after entering puberty, the growth rate of the upper body begins to accelerate and gradually exceeds that of the lower limbs, and the height growth in late adolescence is dominated by the growth of the upper body. "Grow tall first grow legs", it is indeed true. So, there must be parents who want to ask, is there a way to make their children's legs grow longer?The answer lies in this issue of popular science.
Recommendations on the Evaluation of Children's Physical Growth in China" and "Expert Consensus on Clinical Practice of Children's Physical Development Assessment and Management" both pointed outThe evaluation of body symmetry is one of the indispensable contents of physical growth assessment, which has important clinical significance for the identification of diseases related to abnormal growth and development, among which the ratio of sitting height to lower limb length (SH LL) and sitting height to height (SH H) are common indicators to evaluate the proportional symmetry of body shape. Calculated metrics:h (height).: 2-year-old children are measured in the recumbent position, and 2-year-old children are measured in the standing position. SH (sitting high).: Parietal-hip length was measured in the recumbent position in the recumbent position in the child's position, and sitting height was measured in the sitting position in the 3-year-old child. ll (length of lower limbs).= height (h) - sh (sitting height).
Data**: What is the use of using the source data of the standardized growth curves of the height and weight of children and adolescents aged 0 18 years in China to analyze these two **?In the process of judging the proportionality and proportionality of children and adolescents, it is essential to choose an appropriate cut-off point. Based on the available research evidence, it is recommended that 2SD be used as a cut-off value for the initial screening of abnormalities when using the reference standard, thereforeWhen parents find that their child's sitting height to lower limb length ratio (SH ll) or sitting height ratio (SH H) is beyond the range of 2SD, it is necessary to pay attention to it and need to undergo a medical examination in time. 
To this question, the answer is no. Theoretically speaking, the growth of children's height before puberty is mainly the growth of the lower limbs, and it seems that doing more lower limb exercises at this stage is conducive to stimulating the epiphysis of the long bones of the lower limbs, and may be able to achieve the purpose of growing into long legs. But in fact, the proportion of body is mainly derived from genetics, and there is almost no room for improvement in the length of the lower limbs1.Xi: Leggings in infancy (may lead to hip dysplasia or even dislocation), standing or walking before 8 months of age (may cause bone bending), use of a walker (may cause bone deformation), love to sit cross-legged or kneeling (may lead to O-X legs), wearing ill-fitting shoes and socks (may lead to foot dysplasia), poor sitting and standing posture will lead to abnormal leg shape, these misunderstandings must be avoided. 
2.Exercise: Studies have shown that insufficient strength of leg muscles is more likely to lead to abnormal leg shape, proper exercise is conducive to leg fitness, children can be encouraged to run and jump squatting sports, but not excessively, and stretch after each Xi exercise. 
3.Correction: If the bad leg shape is severe, consult a doctor and consider wearing orthoses or orthopaedic shoes depending on your child's condition. In addition, it may also be effective to improve by massage or manual correction in the ** department of a regular hospital.
