Document Summary

Humans experience a prolonged period of physical growth. Infancy body size change us the most rapid: growth slows down by early to middle childhood. Two types of growth curves used to track overall changes in body size: distance curve: plots the average size of a sample of children at each age, indication typical yearly progress toward maturity. Shows that weight & height follow a similar trend (increase linearly) Notice that boys & girls are similar but then girls become taller (age 10-11) but then boys later: velocity curve: plots the average amount of growth at each yearly interval, revealing the exact timing of growth spurts. Rapid but decelerating growth in infancy; slower, constant during early-middle childhood & sharp increase during adolescents; followed by decrease in adulthood. As overall size increases, parts of the body grow at different rates. In puberty it is in reverse, the limbs grow faster, followed by torso.
