Document Summary

Adolescence: the period of final developments to reach adulthood. Take place approximately from age 11 to 21. As a summary of the development during this stage we see: puberty, weight, height and body composition gains. This is the time where a physical transformation of child to adult takes place. This means there is sexual maturation, increased height and weight (a large period of growth and then a bit of plateau) completion of the skeletal growth as well as changes to the body composition. For females, weight gai(cid:374)ed duri(cid:374)g this ti(cid:373)e is the body"s way of sayi(cid:374)g she is mature enough to carry a child. The peak or weight gain is 3 6 months after her big linear growth spurt but before menarche. This weight gain consists of both lean and fat mass. Proportionally there is a more fat mass gained. In summary bone mineral content increases exponentially from age 10.
