Physiological changes in girls during development

We all know that the fastest period of human development is puberty. During this time, both males and females will develop rapidly with the increase of sex hormones in their bodies, especially the second organs will develop particularly obviously. However, girls' development period is generally earlier than boys. Many girls begin to enter physiological development at around ten years old. So what are the physiological changes in girls during their development period?

The puberty period for girls refers to adolescents aged 11-16. Children in this period are in the stage of physical and mental development.

Adolescence is a period of rapid physical development until an individual reaches maturity. Children in this stage experience significant changes in their physical, psychological and social development. Its main feature is rapid and unbalanced physical and mental development. It is a period of complex development and full of contradictions, so it is also called a difficult period or a crisis period.

Accelerated development

The rapid physiological changes of puberty are caused by a rapid increase in hormone secretion. The physical changes during this period can be divided into two aspects: accelerated growth of the whole body and sexual maturity. The two are interconnected and regulated by changes in hormone secretion.

Physical Growth

Adolescence is the peak period of individual growth and development. During this period, the body and physiological functions undergo rapid changes, becoming the peak period of growth and development, which is also the second acceleration period. Children during this period experience very obvious changes in height, weight, shoulder width and chest circumference.

1. Rapid height growth

Rapid growth in height is the most obvious feature of physical changes in children during puberty. According to statistics, before puberty, children grow an average of 3-5 cm per year. During puberty, they grow an average of about 6-8 cm per year, and may even grow as much as 10-12 cm.

2. Rapid weight gain

Weight is an important indicator of physical development. Weight reflects muscle development, bone growth, and the enlargement of internal organs. The average annual weight gain of children during puberty is 4.5-5.5 kg.

Physiological functions

The physiological functions of adolescent children also increase rapidly. Changes in muscle and fat make males have strong muscles and females have fuller bodies. The brain and nervous system gradually develop and mature.

As puberty accelerates growth, children and adolescents experience noticeable changes in their body shape and facial features. Through this change, their physical features begin to approach those of adults.
