The second stage is adolescence. Generally, in junior high school, the height of boys increases rapidly, ranging from 14 to 17. Of course, those who develop late may not grow obviously until 17 years old.
Height mainly depends on epiphyseal closure, and everyone has subtle differences. In the case of epiphysis imperfecta, it is likely to grow even after the best growth period.
Children's height growth, whether boys or girls, the fastest growth time is before the baby is 2 years old.
The height of a baby at birth is generally about 50cm, and it will generally increase by 25 ~ 27 cm in the first year of life. In other words, when the baby is one year old, his height is almost 76.5cm, which is much faster than adolescence. Especially in the intense growth period of the baby, clinical records can increase the height of 1cm within 24 hours!
In the second year of the baby's birth, the height growth is still developing rapidly. By the time the child is 2 years old, his height is almost 87 ~ 89 cm, which means that the annual growth of his height in the second year can reach 10.5 ~ 12 cm, which is almost the same as the peak of puberty development.
After the baby is 2 years old, the growth and development begin to slow down. In the third year after birth, the child's height increased by about 7 ~ 8 cm. After that, the growth of height gradually slowed down until the child entered adolescence.
Boys generally enter puberty at the age of 10 ~ 1 1. In recent years, it is a pity that some boys enter puberty before 10 due to the influence of children's adequate nutrition and food sex hormones. Men are one year later than girls, and girls generally enter puberty from 9 to 10.
The puberty development of boys is marked by sexual maturity. When the child's beard is long enough to be cut off, it means that the boy's height growth is coming to an end. Of course, the accurate method also needs to measure bone age. The older the bone age, the smaller the room for children's height growth.
The peak period of adolescent development of boys can increase by10 ~1cm every year, and the peak period is generally only two years, while the height growth in the late adolescence is only about 5cm per year. Children enter puberty one year in advance, and the growth space will be reduced by about 9cm. If a boy enters puberty one year later, his height will increase by 5cm. This is a universal law.
1, keep enough milk and don't be picky about food.
Milk is a very good food for children, because it also contains a lot of protein and calcium. My two children have been fond of drinking milk since childhood. The older one drinks two packs of milk every day in college, and the younger one drinks milk as water every day. As long as the children are willing to drink, parents should supply enough. Both my children are taller than their peers, which is related to insisting on drinking milk. Of course, other nutrients should be sufficient, and you can't be picky about food.
2. Get enough sleep.
Every night from 9: 00 am to 1 pm, which is the peak of growth hormone secretion. Growth hormone stimulates the growth of children's bones, so children should go to bed before nine o'clock every night. Children sleep no less than 1 1 hour every day before they are one year old, no less than 9 hours every day when they are two years old, no less than 8 hours every day before they are five years old, and no less than 7 hours every day for adolescent children. Otherwise, it will affect the height growth of children.
3. Keep exercising every day.
After the child is three years old, the liver system is relatively developed, and vitamin D can be supplemented by sunbathing outdoors. Vitamin D promotes the absorption of calcium and helps the baby grow taller.
After the baby is 5 years old to adolescence, he can insist on outdoor sports every day. Including skipping rope, playing football, playing basketball, high jump, long-distance running and so on. These exercises can stimulate bone development and delay premature epiphyseal fusion.
Parents should not scold boys often.
The growth of children's height is related to their mood and mental state. The American Academy of Pediatrics found that long-term emotional stress, anxiety, depression, and parents often scolding their children will all affect the secretion of hypothalamic growth hormone, especially children who often suffer from insomnia.
Therefore, parents should not scold their children often, understand them more and pay attention to the way they talk to them, otherwise they may cause their children to be short. Parents should also pay attention to this!
5. Let children eat less junk food.
In particular, foods containing hormones in foreign fast food can lead to precocious puberty in children. For example, children should try to eat less chicken, such as chicken skin, chicken neck, animal internal organs and so on.
People in China attach great importance to height, and many girls like tall boys when looking for a partner. So the question is, when is the peak of boys' height?
In fact, children have two growth peaks, the first peak is infancy, and the second peak is adolescence. For the sake of children's future height, parents must not miss these two peak periods.
Most children are about 50cm in length at birth, and they grow fastest in the first year, with an average growth of 20-25cm, which means that most babies can grow to 70-75cm when they are 1 year old. The growth rate of 1 to 3 years old has slowed down, but it can still increase by 8- 10cm on average every year. After the age of 3, the growth rate gradually decreased. The first peak of children's development is before the age of 3, which is why so many parents want their children to win at the starting line. Laying a good foundation before the age of 3 is of great help to children's future development.
The second peak is our adolescence. Due to the difference of individual physique, the age at which each person enters and ends puberty will be different, mostly between 13 and 19. Puberty, boys can grow 20 ~ 30cm, girls 15 ~ 25cm. Whether a person can have long legs is especially critical in adolescence. After puberty, the height is basically stagnant.
Dr. Wu grew up with a weak foundation and was one of the shortest people in his class until he graduated from junior high school. Boys, if weak, will be laughed at by their peers and feel inferior easily. Fortunately, I fell in love with sports in the third grade. I insist on running and playing basketball almost every day, and my appetite has increased. In my freshman and sophomore years, I suddenly grew from 1.5 meters to 1.7 meters. I didn't realize at that time that I always had leg cramps when I slept at night. I didn't even know it was calcium deficiency. I feel a little regretful when I think about it now. If I had seized the opportunity of adolescence, maybe I could have grown a few centimeters.
Finally, Dr. Wu reminded parents who want their children to grow taller that they must not miss these two golden periods. During these two periods, we must balance children's diet, ensure adequate exercise and sleep, which plays a vital role in children's height!
In my personal experience, it should be in junior high school and high school!
When I was in junior high school, I found that some boys in our class grew to more than 170, and some grew to more than 160. I was short in our class at that time. I'm only a freshman 130, even if I graduate from junior high school, it's only about 145. I was basically sitting in the front row.
But after high school, my height began to grow. By the time I graduated from high school, my height had reached 172, basically eight or nine centimeters a year. I remember when I was in senior three, there were more than 50 people in our class, and my height should be in the top five. Obviously, I used to sit in the front row because of my height, and then I slowly got to the middle position. if I ...
Looking at the gay clubs in my previous junior high school, I found that the senior high schools that grew from junior high school to 1 m 6 1.7 were basically not long, and most junior high school students who are taller than me are shorter than me now.
Maybe many people will say that our height is only 170, but now many people are 180. I can only say that I came from the countryside after 1980s. At that time, rural students were not tall, unless their parents were tall, it was obvious. At that time, the food they usually ate was not so nutritious, so people at that time were not as tall as young people now!
Basically, there are only two stages of height development for boys: junior high school and senior high school, and most of them will be one of them!
The growth of children's height, regardless of boys and girls, is divided into two stages. The first stage is infancy, and the body will grow rapidly from birth to 3 years old.
The second stage is adolescence, and the height of boys generally increases rapidly in junior high school, and the age is between 14- 17. Of course, the height mainly depends on the epiphyseal closure, and everyone has individual differences. A few late-growing types (less than 65,438+0%) also have a long time and space when the epiphysis is not completely closed. Those who develop late may not increase significantly until 17 years old.
Most children are about 50cm in length at birth, and they grow fastest in the first year, with an average growth of 20-25cm, which means that most babies can grow to 70-75cm when they are 1 year old. The growth rate of 1 to 3 years old has slowed down, but it can still increase by 8- 10cm on average every year. After the age of 3, the growth rate gradually decreased. The first peak of children's development is before the age of 3, which is why so many parents want their children to win at the starting line. A solid foundation before the age of 3 is of great help to children's future development. Every oak tree must be an acorn. The pit in infancy is so big that it is difficult to fill it later.
The baby's height at birth is generally about 50cm, and it will generally increase by 25 ~ 27 cm in the first year of life, which means that the baby's height is almost 75cm when he is one year old, which is much faster than adolescence.
In the second year of the baby's birth, the height growth is still developing rapidly. By the time the child is 2 years old, his height is almost 90cm, which means that the annual growth of his height in the second year can reach 10.5 ~ 15 cm, which is similar to the peak of puberty development. Of course, there is not much difference between men and women at this time. And there is no obvious difference between boys.
After the baby is 3 years old, the growth and development begin to be gentle. In the third year after birth, the child's height increased by about 7 ~ 8 cm. After that, the growth of height gradually slowed down until the child entered adolescence.
The second peak is our adolescence. Due to the difference of individual physique, the age at which each person enters and ends puberty will be different, mostly between 13 and 19. Puberty, boys can grow 20 ~ 30cm, girls 15 ~ 25cm. Whether a person can have long legs is especially critical in adolescence. After puberty, the height is basically stagnant.
Boys generally enter puberty at the age of 10 ~ 1 1. In recent years, it is a pity that some boys enter puberty before 10 due to the influence of children's adequate nutrition and food sex hormones. Indicates that the height is fixed, not exceeding 160 cm.
When the boy's voice changes, it means that he has entered the late adolescence. At this time, the space for height growth will generally not exceed 10 cm, which means that the boy's height growth is coming to an end. Of course, the accurate method also needs to measure bone age. The greater the difference between bone age and actual life age, the smaller the room for children's height growth.
The peak period of adolescent development of boys can increase by10 ~1cm every year, and the peak period is generally only 2 or 3 years, while the height growth in the late adolescence is only about 5cm per year.
Boys, if they are short, will be laughed at by their peers, which will easily lead to inferiority complex and affect their family, career and life in the future. Fortunately, my son has been managing his height since he was born, and he likes sports. He insisted on running and playing basketball almost every day, and his appetite increased. His sleep quality is good, and his care and efforts in nutrition and health injuries have enabled his children to create a miracle of height management.
If the child is not tall, it will lose more than 10 thousand, and the growth hormone will be more than 10 thousand to 200 thousand. The reason is the lack of height management awareness, understanding of height management, understanding of technology, and lack of height management guidelines. Our column is to teach you how to do it (mom height 157, dad height 163, 7-year-old son height 65438+). Not only did I break through the genetic height of 10 cm, but in my series of courses, I will tell you five different types of cases and various experiences of growing taller in my life. After listening, you can also make a plan for your child to grow taller.
Height is an important part of boys' self-confidence. What a proud experience it is for a boy to grow from an arm-length baby to a tall and handsome boy. However, it takes time for boys to grow taller.
Generally speaking, girls grow faster than boys, and boys grow taller than girls. Parents often feel a little confused and even anxious about the fact that boys have never grown tall. They are eager to know when boys grow fastest.
When do boys grow fastest?
Adolescence is a rapid development stage before human growth and maturity, and it is also the peak of height growth. It can be roughly divided into three stages:
1. Pre-puberty: boys begin at the age of 13- 14 and generally last for 2-3 years.
2. Mid-adolescence: Boys start from the age of 14 to the age of 16, mainly develop sexual organs and secondary sexual characteristics, and have nocturnal emission, which generally lasts for 2-4 years.
3. Late adolescence: boys start from 17 years old to 18 years old, which is mainly manifested in the slow development and gradual maturity of various systems of the body.
In general, the height of men grows fastest between 12 years old and 16 years old (middle adolescence), and the height growth at this stage is often as high as 30 cm. Boys are actually the heaviest in this period.
Most of the growth during this period is in limbs, legs, feet, hands and hands. It is for this reason that most teenage boys look clumsy because they are used to physical changes. During this period, hair began to appear all over the body, and the vocal cords also changed. During this period, the skin begins to become very greasy, which usually leads to acne. But by the age of 18, the height is getting higher and higher, the body is getting wider and wider, and the body is getting stronger and stronger.
However, it is rare for men to grow up to 265,438+0 years old. There is even one exception. Boys may grow up to 25 years old.
Other common questions about male growth:
What factors determine a person's height?
Environment and heredity play an important role in determining human height. These factors are basically a combination of heredity, eating habits and hormones, and stress is the only factor that reduces height.
Your height = (heredity+hormone+nutrition)-stress
How old is a man's penis?
Boys' penises will grow until the end of adolescence. The main question is at what age does the boy's puberty end? The answer to this question varies from person to person. One person may end puberty at the age of 14, and another person may end puberty at the age of 16. However, in most cases, once a boy reaches the age of 16, most people's body organs will stop growing and maturing.
Growth hormone? What are they?
Growth hormone will continue to stimulate the growth of the body until puberty is completed. Growth hormone is released from the pituitary gland deep in the brain. When you sleep and exercise, hormones begin to be released in large quantities.
How much weight is most conducive to height growth?
Your ideal weight is easily determined by your height. For men, the rule of thumb says that if you are tall 152cm, then your weight should be close to 48kg. If your height is 157cm, then your weight should be close to 154kg. Therefore, for every 3 cm height of 152cm, your weight will increase from 3kg to 48kg.
How do boys grow up fast and tall?
1. Balanced diet and nutrition
Nutrition obviously plays an important role in determining a person's height and answering this question: When does a man stop growing? You should add vitamins, calcium and zinc to your diet as much as possible. Zinc and calcium will significantly strengthen your bones and help stimulate growth. The effect of extracting growth hormone from vitamins is obviously the best, so you should mix vegetables and fruits in your diet to get vitamins that can make better use of growth hormone.
Sleep well at night.
When people fall asleep, HGH (Human Growth Hormone) is released. Sleep is very important for the growth of height. In addition, the body actually grows the most during sleep, so the more sleep, the higher the height.
do morning exercises
Morning stretching can help boys grow taller. Because of a * * * knowledge, gravity will affect your body length, and this influence will decrease with time. Your body stretches after sleep and reaches its highest height. To ensure that your body actually starts from the highest height of the day, stretching in the morning can help stretch your bones.
take exercise
If you are young, exercise can increase your height, because growth hormone will be released after every exercise. So, try to play ball, jump, run, swim and ride a bike, and your height will increase.
What sports do boys do to help them grow taller?
① Play more ball games. Basketball and volleyball are both ok. Jump as much as possible, and do more jump-related actions such as smash and block.
2 jump up and touch the height. When jumping, touch the height with your hands. For example, you can exercise by walking, but you can exercise by the branches on the roadside. Jump with your feet and do it 20 times.
③ Hanging exercise should be arranged every morning, and the body should relax and droop for 20 seconds as much as possible, and should be done 10 ~ 15 times each time.
④ Do 50 squats every day to stimulate the articular cartilage of the legs and accelerate bone growth during exercise.
⑤ Pressing leg press every day when you are free can stretch tendons and help you grow taller.
Try massage
Massage not only promotes metabolism, is conducive to bone development, gets twice the result with half the effort, and is simple and easy to implement. Massage of acupoints and meridians can increase the operation of meridians and the nutrition of qi and blood in the whole body. Boys had better try massage after exercise.
6. Your body posture is very important
A good posture is necessary to keep your body straight and make you look as tall as possible. If you hook up for a long time, it will adversely affect the curvature of the spine. So it is very important that you practice a posture of keeping your chin up, and your hips are directly pressed against your feet, so that your shoulders will not be low.
7. Dietary taboos that are not conducive to growth
Gluttony: Boys have big appetites and vary in size. If they want to satisfy their appetite and lose weight, they should choose to eat more fruits and vegetables.
Drink less: Because alcohol is high in calories, it replaces the burning effect of fat and naturally gains weight.
Carbonated drinks: Boys drink a lot of carbonated drinks after exercise, especially cola drinks with high phosphorus content. Excessive drinking leads to imbalance of calcium and phosphorus in the body, which leads to stunting.
The peak of boys' growth is adolescence, which generally begins in the second grade and ends in the third grade, that is, 18 years old, which is the development law of most people. Of course, a few people will develop sooner or later.
My child began to show some signs of development in the second semester of Grade Three. Before that, he was like a child and was mistaken for a pupil several times. By the time I was a freshman this year, I felt that I had suddenly grown up. Shoes, trousers and clothes are always too short. I didn't know until I measured my height. It's almost 1.7 meters.
In adolescence, keeping proper exercise every day, playing ball, skipping rope and doing more things beneficial to the body and mind are all helpful to the growth of height.
Adolescent height growth is rapid, consumption is large, reasonable diet, eating more foods rich in calcium and trace elements, and ensuring the supply of nutrition can provide enough nutrition for height growth.
The growth peak of most boys is in adolescence. Speaking of tall people, it's spring again, and many mothers are beginning to worry. In fact, every child is different. Don't worry too much.
Adolescence is the second peak of growth. Boys and girls are the same, but their puberty age is different.
I remember grandma said that some boys play late, and the old saying goes that they run around at the age of 20, which means that some boys may grow up at the age of 20.
Adolescence is a stage, some children grow up as soon as they enter adolescence, and some children grow up slowly throughout adolescence, and later they find that they have grown very tall. And some children, grasping the tail of adolescence, began to grow up. So every child is different, so parents should not worry too much.
Adolescence is also a relatively heavy academic stage. Unbalanced school diet, lack of sleep, and monthly pressure will all affect children's height. Parents should give their children more knowledge and don't exert too much pressure.
One of my junior high school classmates thought he was short when he went to school, so he dropped out of school. See you again a few years later, he is taller than those students.
And a childhood playmate. His mother is short and his father is tall, but he didn't have long hair in high school. As a result, he went to college for a year, almost as tall as his father.
Generally speaking, adolescence is the peak of boys' growth, but adolescence is a stage, and different children grow up early.
For boys, the development is generally slow, and most of them stop growing around the age of 20, while the growth of boys' height generally stops before the age of 23, so male friends who want to grow taller must make full preparations for the growth of height in the golden age of growth.
The basic period of growth and height is generally in infancy 1-9 years old, and the sudden increase stage of growth and height is adolescence 10- 16 years old. At this time, the height growth is obvious, more food needs to be consumed, and the demand for calcium ions also increases. The final sprint period of male and female growth and height is 17-22 years old.
The key to the growth of human height depends on a cartilage tissue called epiphyseal line at the top of long bones, which is different from other cartilage tissues in the body. With the growth and development, the epiphyseal line will gradually ossify until it is completely ossified. When ossified completely, it is often said that the epiphyseal line is closed and the height will not grow.
To grow taller, male friends should first have a balanced nutrition, eat more foods rich in protein, such as beans, shrimp, crabs, chicken, pork legs, eggs, milk, etc., and try not to eat cola, fruit juice and desserts. Even if they want to eat, it is best to eat less, because it contains a lot of sugar, which will hinder the body's absorption of calcium to a certain extent, thus affecting the development of bones.
In order to grow tall and healthy, you need to supplement your body with enough vitamins every day, and you can't ignore breakfast. You must eat breakfast, and exercise is also good for your height.
With the improvement of economic level, most children have good nutritional status. Excessive intake of high-calorie and high-tonic foods can easily lead to premature growth of children, with relatively early development time and younger age, but it has reached the development stage. The growth rate during this period will be much faster than usual.
