Document Summary
Body composition can be used to monitor body changes, determine morbidity and mortality risks, and establish measurements baselines. Body composition assessment tools include bmi, waist circumference, and w/h ratio, bia, skinfold analysis, and hydrostatic weighing. Equation: weight (lbs) x 703 / height (inches squared) Not valid for assessing types of mass. Generally, poor application when it comes to athletes, older adults, and other racial/ethnic groups. Android: apple shape, more fat in the upper body. Typical body shape is seen in males. Gynoid: pear-shaped, more fat in the lower body. The typical body shape is seen in females. Whr equation: wais measurement / hip measurement. Not great at differentiating body composition type. Bia: device estimating percent body fat with electrical impulses. Passes through muscle easier than fat due to higher concentration of water and electrolytes. Results rely on hydration levels and skin temperature. Skinfold analysis: using the thickness of skin on various part of the body to assess body fat percentage.
