Normal height for a 15-year-old boy

The standard height of a 15-year-old boy, the development of a 15-year-old boy, the average weight is 57kg, the minimum is 41kg, and the maximum is 80.5kg. The average height of a 15-year-old boy is 170cm, the minimum is 157.5cm, and the maximum is 180cm. According to the regularity of children's development, most boys enter puberty at around 12 years old.

The growth rate in the first two years is relatively fast. When you are 15 years old, the growth rate has significantly decreased. If your height is not ideal, you should catch up in the last few years. Although the last two years are long, the growth rate each year is not large. Therefore, the nutritional content should be sufficient, calcium, zinc, and protein intake should be ensured, and calcium zinc traditional Chinese medicine preparations can be supplemented appropriately. You should do vertical jumping activities, such as playing basketball and jumping crickets, and ensure that your child has high-quality and sufficient sleep.

From the perspective of cell biology, a boy who has completed his growth and development will generally be taller than his middle-aged or elderly father, but 10-15 cm taller than his mother. In other words, if his parents are not very tall, it is difficult to grow taller.

Although theory says that more than 70% of a person's height is genetic, the remaining less than 30% can still be used well.

First, you must not miss any of the three meals a day, and eat according to the ratio of 3:4:3 from morning to night. But this does not mean that you can only eat that much at night. You must eat until you are full, but it may not be as nutritious as in the afternoon. Second, you must give up soda. Other high-fat drinks can be avoided. Drink more water and eat more fruits. If you really can't give up soda, only once a month, otherwise it will cause great harm to your body. Third, you must exercise. The only exercise that can make you taller is to stretch and stretch, basketball, tennis, badminton, jumping flies, choose a favorite, and stick to practicing for more than 10 minutes a day. Don't pursue the daily training time, but make sure to practice every day. Fourth, don't stay up late often. Teenagers who often stay up late will directly affect the metabolism of growth hormone. If they cannot metabolize it, they will certainly not grow. Therefore, it is best for teenagers to go to bed around 10 o'clock at night. If they really have to go to bed at 11:30, the strongest time for hormone metabolism is from 21:30 to 1:00.

In addition, don't feel disappointed that you are almost 15 years old. In fact, after the first growth spurt of boys' growth, they will grow very little or even sooner for 2-3 years. This period is around 14-16 years old. There will be another growth spurt after the age of 18, but that is not entirely due to human growth and development. Most biologists believe that it is at a certain stage when everyone has just finished the college entrance examination. The human body has been completely relieved of stress, and organs such as the pituitary gland will also reduce nervous tension and begin to actively secrete growth hormone. Therefore, at that time, boys may also grow 2-5 cm. If the stress is well relieved, it is not impossible to grow 7.8 cm. The time is approximately between 18 and 25 years old. After 25, the bone hyperplasia is closed and it is basically difficult to grow anymore.
