Document Summary

Girls gain 1. 14 kilo per year in fat. Boys do not have huge fat mass, but rather fat-free mass (ffm). It occurs at a greater rate and occurs for a longer time than girls. Post-adolescence, boys tend to be leaner than boys. At around 8-10 years old, boys have about 24kg of fat-free mass at about 15% body fat. At around 20 years old, body fat should go down to around 13% body fat and about 60kg of fat-free mass. Bone mass doubles between the onset of puberty and young adulthood. Can continue to grow up to 2 years after phv. Boys are about 10% taller than girls and have a 25% greater potential of peak bone mass. Females tend to test positive before and more than males. When growth plates fuse post-puberty, bone mass development is 90-95% of peak bmd. The pattern of hormone secretion: hormones have effects on bone, adipose tissue, and sexual development.
