Evaluation Of Factors Determining The Precision Of Body
Techniques for the measurement of body composition a practical guide. 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. Since the density of an object in this case your body equals mass divided by volume we know mass equals your body weight. Many techniques are available for body composition assessment which range from simple indirect measures to more sophisticated direct volumetric measurements. We know the density of fat muscle and bone and water. Skinfold calipers measure the thickness of your subcutaneous fat the fat underneath the skin at certain body locations. Measurements are taken at either 3 or 7 different sites on the body.
Volume is measured by the bod pod. 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. Int j obesity 199317611 621. Techniques for the measurement of body composition. All measurements for men and women are to be taken on the right side of the body with the tape parallel to the deck. Techniques for the measurement of body composition.
Comprehensive review of practical and research methods used for measurement of body composition. 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. When measuring circumferences apply the tape measure so that it makes contact. The technician pinches the. 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.
The pod measures the volume of air you displace allowing the bod pod to measure your overall density. This measures total body water which can be used to determine total fat free mass. Comprehensive review of body composition assessment.
