Body Fat Analyse
One way to analyse body fat is through near-infrared interactance. In this technique, the examiner will make use of a beam of infrared light and will shine it through one’s biceps. The underlying muscle mass of the biceps will reflect the beam back. The body’s fat will absorb this light and then depending on the amount of light that is actually returned to the point of origin, a fairly accurate measurement of one’s body fat can be determined. You then have the dual energy X-ray absorptiometry technique used to analyse body fat. Also known as DXA or DEXA, this technique makes use of two different forms of X-rays. The first X-ray will scan the body of all tissues; this includes fat, skin, muscles, bones and organs. The second X-ray will then scan the body however this particular X-ray is not capable of detecting fat tissue. Then using a computer, the first X-ray scan will be subtracted by the second one, leaving only the fat tissue in the computer. From there the actual mass of the fat tissue will be calculated and then the body fat percentage will be determined. There are many other techniques available as well that can include things like measuring the amount of body fat inside the bones as this fat is also found within bone marrow. Then there is also a technique that can be used to determine the amount of water in the body as well as the actual volume of fat in the body through displacement testing. However, the most refined and accurate technique that can be used is known as the in-vivo neutron activation technique. In this technique, all the different components associated with the body and its fat is analysed in order to determine the amount of fat in one’s body. Of course this method is also the most expensive and the hardest to find as well.
