Document Summary
1. 5- widths: proportionality (ratio or index, to calculate how one body segment compares to another segment. In general, females have longer trunks, relative to their legs, than do males. If a male and a female have identical standing heights (stature), the female will usually have a greater sitting height. 2. 2- mass: stature proportions, body mass index (bmi) This is your body mass (weight) relative to your stature (height). As you increase in height (a linear measure), your surface area squares, but body volume cubes. This ratio is your mass (weight) relative to height squared . Crural index (lower leg relative to upper leg) Brachial index (lower arm relative to upper arm) Hip relative to waist (see body composition) Children versus adults: children have a large surface area relative to their volume so they are more cold sensitive (recall, as your height increases, your surface area squares but volume cues, composition, two-component" model. Most common method used in composition analysis.
