Standard height and weight for 12-year-old boys

At the age of 12, the height should be around 140 cm. The growth and development of children is a continuous process, but it does not proceed at a uniform speed. For example, the growth and development of the human body is faster in the baby stage, then gradually slows down, and then speeds up again in the puberty period, entering the second growth and development peak. The development trend of many abilities is also like this. There is a period of obvious development, and the next stage of development will become slower, and even no changes can be seen. But this is not stagnation, but "accumulation", and "preparation" for another leap.

1. Standard height and weight for 12-year-old boys

The standard height and weight of a 12-year-old boy is calculated according to the formula. First, weight (kg) = age X2 8, that is, 12X2 8=32kg, and the height calculation method is age X7 7=159cm. 12 years old is the peak period of growth and development for children. If the child can have sufficient nutrition, moderate exercise, and then sufficient sleep, the child's height can increase rapidly at this time, but the height of children varies, for example, it is affected by various aspects such as genetic inheritance, living environment and habits.

Children aged 12 are in a critical period of growth and development. It is important to ensure that they have adequate nutrition, do not be picky eaters, and develop a good diet structure; eat a balanced diet, do not eat snacks, frozen foods, fast food, etc. Moderate sports competitions can also speed up basic metabolism and help height growth.

2. How can a 12-year-old boy grow taller quickly?

1. Regular exercise will stretch your spine (it is not recommended to use equipment for stretching, which has no scientific evidence and has side effects). It will increase your spine by 2 to 5 cm compared to not playing basketball. Moderate exercise can improve the blood supply to the bones and increase the normal value of bone density. Only then can the increase become possible!

2. If you are developing during puberty, you can take calcium tablets for pregnant women to supplement the calcium loss after exercise so that the bones can be replenished. However, calcium is a substance that is difficult to digest and absorb. First of all, if you can buy calcium citrate, you can avoid being destroyed by stomach acid and dilute most of the high-quality protein, which will be very beneficial. However, in order for calcium to be absorbed by the colon, it must have vitamin D. Therefore, you must take vitamin D at the same time or first, and then take calcium citrate. If it is difficult to buy, buy calcium lactate, and then calcium gluconate. If you can only buy calcium bicarbonate, the actual effect will be destroyed by gastric juice, which is more serious.

3. Don’t think that eating bone soup and other pure calcium bicarbonate foods is effective, because this food also contains high phosphorus, and the best calcium-phosphorus ratio for humans is 2:1. High phosphorus will promote calcium outflow, so it is not scientifically proven to think that form will fill the form. The tragedy is that you cannot separate calcium and phosphorus when drinking bone soup, so drinking it will not work. If there is too much phosphorus, it may also have adverse effects!
