Document Summary

4 major parts fat free mass, fat mass, bone mineral, water. Of no value for living except to get average tissue densities. Limitation anyone with substantial muscle mass will be in obese range. Narrowest point for waist, widest for hips. Android (apple) vs gynoid (pear) and health implications. Females > 0. 85; males > 0. 95 at higher risk for chronic disease. Men tend to accumulate body weight in the stomach, women in the hips and thighs. Because tissue density differs, overall body density affected by relative composition. Mass (weight) measured on any accurate scale. Volume assessed by hydrostatic weighing (underwater weighing) Fat and fat free masses estimated based on tissue densities determined from cadaver analysis. Generally considered one of the best in vivo measures. Hydrostatic weighing equipment as little as -2000. Air displacement (bod pod) ranges from ,000-70,000. Relationship between subcutaneous fat and total fat (based on densitometry determined by body fat; relationship can differ from group to group)
