Methods of Body Composition Assessment

摘要: Body composition refers to the physical material that makes up body. This chapter focuses on body assessment in humans. Because of health effects excess fat (e.g., increased risk Type 2 diabetes, heart disease, cancer) and being underweight anorexia nervosa), because deleterious athletic performance, quantifying terms percent has important uses for implementing monitoring weight loss programs). In addition, fat-free mass its components (muscle, bone) is implications sarcopenia osteopenia/osteoporosis. The characterization can be divided into two broad divisions: levels models. Herein, “levels” are briefly examined. These include atomic, molecular, cellular, tissue-system, whole-body levels. Specific techniques determining such as underwater weighing, skinfold assessments, bioelectrical impedance analysis, dual-energy X-ray absorptiometry then Finally, different “models” analysis explained. models segregate compartments, currently there two-, three-, four-component
