At what age range do children typically start experiencing growth spurts associated with puberty?

Children typically begin experiencing growth spurts associated with puberty around the ages of 9 to 11 years. This period marks the onset of puberty for many children, with biological changes leading to increased height, weight, and changes in body composition. The growth spurt can vary slightly between individuals, but these years are generally recognized as the time when physical development accelerates significantly as hormone levels rise, particularly with the onset of menarche in girls and testicular enlargement in boys. This age range is critical for the onset of physical maturity, which includes a variety of developmental changes.
