Pitfalls In The Measurement Of Muscle Mass A Need For A
Techniques for the measurement of body composition a practical guide. Review articles jebb sa elia m. Comprehensive review of body composition assessment. Measurements are taken at either 3 or 7 different sites on the body. Comprehensive review of practical and research methods used for measurement of body composition. Volume is measured by the bod pod. We know the density of fat muscle and bone and water.
Some techniques measure gross composition in terms of fat and fat free mass or the components of fat free tissue such as water mineral and protein while other methods measure the mass of individual tissues organs or body segments. This paper discusses some of the practical aspects of both reference body composition methods densitometry isotope dilution methods in vivo neutron activation analysis dual energy x ray absorptiometry computerized tomographic scanning and magnetic resonance imaging and bedside or field techniques weight and height indices skinfold thicknesses impedanceresistance near infra red interactance and 24 hour creatinine excretion. All measurements for men and women are to be taken on the right side of the body with the tape parallel to the deck. Many techniques are available for body composition assessment which range from simple indirect measures to more sophisticated direct volumetric measurements. Int j obesity 199317611 621. This measures total body water which can be used to determine total fat free mass.
Some of the methods that are used today include anthropometry tracer dilution densitometry dual energy x ray absorptiometry air displacement plethysmography and bioelectrical impedance analysis. Techniques for the measurement of body composition. Since the density of an object in this case your body equals mass divided by volume we know mass equals your body weight. When measuring circumferences apply the tape measure so that it makes contact. Bioelectrical impedancea way of assessing body composition by measuring the flow of a small electrical current through the body. Skinfold calipers measure the thickness of your subcutaneous fat the fat underneath the skin at certain body locations.
Perhaps the most accessible method for measuring body composition a skin fold assessment can be done using either three four or seven sites meaning parts of the body. The pod measures the volume of air you displace allowing the bod pod to measure your overall density. Some techniques measure gross composition in terms of fat and fat free mass or the components of fat free tissue such as water mineral and protein while other methods measure the mass of individual tissues organs or body segments.
