Understanding the significant physiological, hormonal, and psychosocial changes girls experience during puberty is essential for supporting their health, athletic performance, and overall well-being. Recognizing these sex-specific differences allows parents, coaches, and healthcare professionals to provide appropriate support tailored to young girls' needs. Ultimately, creating informed, supportive environments helps teenage girls navigate these transformative years successfully and confidently.
- Hormonal Influences: Puberty initiates major hormonal shifts, notably estrogen, progesterone, and testosterone, influencing metabolism, mood, and physical characteristics distinctly in girls compared to boys.
- Puberty Timing and Variability: Girls typically begin puberty around ages 10–14, with significant individual variability; this timing can be affected by genetics, nutrition, physical activity, and environmental factors.
- Physical and Biomechanical Changes: During puberty, girls experience rapid growth, bone mineralization, increased body fat, pelvic widening, and changes in center of gravity, potentially raising the risk of injury (e.g. ACL injuries).
