Multicomponent Models of Body Composition: An Overviewevelopment are presented in earlier reports (Heymsfield 1990, 1991, 1996, Wang 1995). A component or “compartment” in body research is one of 35–40 discrete clearly defined atomic, molecular, cellular, or tissue-system level entities, as shown in Figure 3.1 (Wang 1992). The sum of all components atinfantile 发表于 2025-3-25 14:46:07
Indicator Dilution Methods97% of body mass is accounted for by the mass of just four elements: oxygen (61%), carbon (23%), hydrogen (10%), and nitrogen (3%) (Wang 1992). Even the remaining 3% is nearly all accounted for when the masses of calcium, phosphorus, sodium, potassium, and chlorine are included. At the molecular levInfelicity 发表于 2025-3-25 16:18:20
Densitometryf determining body volume, and thus body density. Hydrodensitometry has been recognized since then as the “gold standard” method for the assessment of body fat in vivo; however, more recently this concept is being questioned.SMART 发表于 2025-3-25 23:50:45
Bioimpedance Analysis contract ex vivo (King 1901). In the late nineteenth century, Vigouroux (1888) changed the field when he postulated that the response of the body following the administration of electrical current might be useful in diagnosing certain maladies. Indeed, hysteria, muscle weakness, epilepsy, and feverDictation 发表于 2025-3-26 02:22:38

Total Body Potassium: A Reference Measurement for the Body Cell Massctors were incorporated into first-generation whole-body counters in response to the health concern that internal contamination would result from work with radioactive materials. Accidental exposures turned out to be rare. These systems were at nuclear facilities involved both in basic research andExpressly 发表于 2025-3-26 15:22:42
