What is a key physical change that occurs during adolescent development?

During adolescent development, one of the most significant physical changes is growth spurts. This phase is characterized by rapid increases in height and changes in body composition that typically occur during puberty. Growth spurts are influenced by hormonal changes, particularly the increase in sex hormones such as testosterone and estrogen, which stimulate growth plate activity and overall skeletal development.

These changes are essential for adolescents as they transition from childhood to adulthood, not only reshaping their physical appearance but also impacting their self-esteem and social interactions. Typically, girls experience their growth spurts earlier than boys, often starting around ages 10 to 12, while boys may start a bit later and continue growing until around ages 14 to 16.

It's important to understand that during this period, adolescents also see an increase in muscle mass and changes in fat distribution, further contributing to their overall physical development. This is in contrast to conditions such as decreased muscle mass or bone density, which do not accurately describe typical adolescent changes. Instead, growth spurts signify normal and healthy development during this formative stage.
