DEXA Body Comp scheduled!
I am such a dork, I am truly excited about my upcoming DEXA Body Composition Analysis ~ its scheduled for 4 weeks from now and it is 99.993% accurate, its separated by each body part even, and you get a full visual display of where the body fat tissue is located. For example it will tell you your total body fat mass, lean mass, organ wieght, skin/water weight, and then things like (head = 12% fat, torso = 6%) so I am beyond curious and will post all my results! A friend had it done recently here in Denver and her head came out to be 16% fat! That is alone, but as a whole her total body fat was 18.1% when calipers had her at 22%, handheld had her at 24%, and hydro (dunking) had her at 20.2%!
She also said her right leg was 2% higher in fat than her left, and that all her abdominal fat could be seen more at the sides and back (love handles); just useful for the obsessed, like me
Here is a more apt explanantion
DEXA (Dual Energy X-ray Absorptiometry) - A relatively new technology that is very accurate and precise, DEXA is based on a three-compartment model that divides the body into total body mineral, fat-free soft (lean) mass, and fat tissue mass. This technique is based on the assumption that bone mineral content is directly proportional to the amount of photon energy absorbed by the bone being studied.
DEXA uses a whole body scanner that has two low dose x-rays at different sources that read bone and soft tissue mass simultaneously. The sources are mounted beneath a table with a detector overhead. The scanner passes across a person’s reclining body with data collected at 0.5 cm intervals. A scan takes between 10-20 minutes. It is safe and noninvasive with little burden to the individual, although a person must lie still throughout the procedure.
DEXA is fast becoming the new "gold standard" because it provides a higher degree of precision in only one measurement and has the ability to show exactly where fat is distributed throughout the body. It is very reliable and its results extremely repeatable; in addition, the method is safe and presents little burden to the subject. Although this method is not as accurate in measuring the extremely obese and the cost of equipment is high, DEXA is quickly moving from the laboratory setting into clinical studies.
