Document Summary
Sitting height/stature x 100: used in growth studies, estimates trunk length to leg length (what percent height is trunk/legs) If you are 54% height ratio 54% is sitting height (torso) Shoulder-hip relations: ratio of bicristal (hips) to biacromial (shoulder) breadths, bicristal/biacromial x 100, become especially apparent during adolescence (wide shoulders athlete) Minorities proportionately represented: after birth, individual growth becomes more expressed, absolute range between 5th and 95th becomes larger with age. Wider range of variation for weight than height. Enter puberty early, going to move up percentiles for your age: growth charts during adolescence do not incorporate individual differences (would be called tempo conditional growth charts) Midgrowth spurt: children may experience small spurt in growth and stature (increase velocity) several years before onset of ags (6. 5 to 8. 5 years of age, occurs more frequently in boys than girls (not all children experience this)
