This chapter begins with a brief overview of the reference body composition methods including underwater weighing dilution methods whole body potassium counting dual energy x ray absorptiometry dxa computed tomography ct and magnetic resonance imaging mri.
One of the measurement of body composition. It then discusses bioelectrical impedance analysis bia and the validity of anthropometric measures particularly self. The specific sites used vary in men and women. As the name implies this method involves pinching the subcutaneous fat layer with fingers and measuring the thickness using a caliper. A measurement of the ratio of fat mass versus lean tissue including muscle bone.
Many of these devices use a technology called bioelectrical. Body mass index vs. Calipers easily portable and measurement is simple and inexpensivehowever this method involves estimating the total. But they often overlook composition as an important metric for monitoring health.
The average of the three measurements taken at each spot is then input into a formula to calculate an individuals body composition. Both markers are supposed to measure how healthy you are but bmi is flawed. It is also known as pinch test. Measurements are taken at either 3 or 7 different sites on the body.
Underwater weighing is regarded as the gold standard for body composition measurement as it is one of the only body composition technologies that have been compared directly to cadaver analysis. The measurement of human body composition allows for the estimation of body tissues organs and their distributions in living persons without inflicting harm. Whether your main focus is rocking a bikini at the beach or living to be 100 there is one important piece of information that may get in the way. Most people are familiar with weight and other bodily statistics.

From a nutritional perspective the interest in body composition has increased multi fold with the global increase in the prevalence of obesity and its complications. For women the triceps area above the hip bone and either the thigh or abdomen. Devices that measure body composition in addition to these simple methods there are devices you can buy that measure body composition.
