Generally, girls enter puberty earlier (on average 2.5 years earlier) than their male counter-parts and therefore their growth-spurt happens earlier.
- On average girls will increase their height significantly between ages 12-16 years.
- The average increase overall in height is 25cm.
- At peak time the growth rate can be 9-10cm per year.
- Girls can still grow between 16-19 years, but this can be slowed or delayed if calorie restrictions happen.
- As much as 50% of ideal adult body weight is gained during adolescence.
- Females peak weight gain is about 3-6 months later than their height gain.
- When height growth is at its peak girls will gain on average 8kg per year.
- Weight gain slows when the first periods start but girls can still gain as much as 6kg during the latter half of adolescents.
- Females experience around 45% increase in lean mass and 120% increase in body fat during puberty (around 1.1kg of body fat each year during puberty).
- Body fat levels peak around 15-15years of age.
- Energy needs are influenced by activity levels.Girls who participate in sports, who are training using large muscle groups,and are more active than some of their peer counter-parts will need more energy (AKA EAT MORE FOOD).
