Boys' developmental characteristics and manifestations

We boys will all go through puberty, and we need to pay enough attention to it. If we don’t pay enough attention to it, it will have a negative impact on our bodies. So when we enter puberty, we must pay more attention and take effective methods to better get through puberty. Maybe everyone does not have a clear understanding of the developmental characteristics of boys. Let us learn about the developmental characteristics of boys together!

feature:

1. Height The occurrence of a height growth spurt is a sign that boys and girls are entering puberty. The height of adolescent boys can increase by 7-9cm per year, up to 10-12cm, and an average increase of 28cm during the entire puberty; the height of adolescent girls can increase by 5-7cm per year, up to 9-10cm, and an average increase of 25cm during the entire puberty. Because boys begin puberty later than girls, their bones stop growing later. In addition, boys' growth spurt is larger and lasts longer, so by adulthood the average height of men is generally about 10 cm taller than that of women.

2. Weight is easily affected by environmental factors such as nutrition and disease, and its stability is less stable than height. It mainly reflects the changes in the quantity of bones, muscles, adipose tissue and internal organs, so it can continue to grow even after puberty. Body weight refers to the total weight of the body, including bones, muscles, fat, internal organs, etc. As girls age, their body fat continues to increase, with a peak in fat accumulation during puberty, when they mature, the amount is twice that of boys. As boys age, their muscles continue to develop, reaching their peak at age 30, and when mature, they are 1.5 times that of girls.

3. Lean body mass and body fat Lean body mass (lean body mass), also known as fat-free body mass, includes the bones, muscles, various internal organs, nerves, blood vessels, etc. of the whole body, also known as metabolically active tissue. Body fat refers to all the fat tissue in the body, but most of it is stored in the subcutaneous tissue, also known as metabolically inactive tissue. The sum of the two is the body's weight. It is a normal physiological phenomenon for girls to have a high body fat content, and there is no need for girls to worry too much about suffering from "obesity". Some girls aged 16-17 do not understand these physiological changes and lack the necessary health knowledge. They mistakenly believe that the thinner the better and are afraid of getting fat so they try to restrict their food intake, which leads to physiological dysfunction caused by morbid psychology, namely anorexia nervosa, which seriously affects the normal development of children and adolescents and should attract the attention of relevant departments. Due to the difference in lean body mass and body fat content between boys and girls, boys have a sturdy body shape with well-developed muscles, broader shoulders and larger chest circumference. Girls, on the other hand, develop a fuller body shape with a high body fat content, a wider pelvis, and narrower shoulders.

The above content introduces us to the developmental characteristics of boys. I believe that all male friends must have their own understanding. These precautions are worthy of our attention. Only by fully mastering these precautions can we help us better go through our adolescence and grow better.
