To get accurate results with this method, you must consult a practitioner who would tell you when you should have the last meal, how much fluid intake you should adhere to and there are other considerations or guidelines to factor in. (1996) observed that weight trainers had lower density of fat-free mass, compared with controls [8]. hydrostaticweighing), according to a 2013 survey[10]. The purpose of this study was to . Body composition measures the proportion of fat and muscle in your body. For example, water, minerals, and protein are thought to have densities of 0.9937 g/cm3, 3.038 g/cm3, and 1.34 g/cm3, respectively [3]. Air-displacement plethysmography offers several advantages over established reference methods, including a quick, comfortable, automated, noninvasive, and safe measurement process, and accommodation of various subject types (eg, children, obese, elderly, and disabled persons). Meyer, N.L., Sundgot-Borgen, J., Lohman, T.G., Ackland, T.R., Stewart, A.D., Maughan, R.J., Smith, S. and Mller, W., 2013. The test involves the participant being lowered into a water tank until all body parts are emerged, expelling all the air from the lungs, then weighed. Its Bioelectric! comments: The Bod Pod technology is fundamentally the same as underwater (hydrostatic) weighing, but uses air instead of water. Graduate School Correlations between the two V(TG) measures on a day were r = 0.86 for day 1, r = 0.93 for day 2, and r = 0.96 for day 3. Not surprisingly, they are all linked. and Burke, L.M., 2012. Effects of exercise sessions on DXA measurements of body composition in active people. A weak electrical current is run through the body to identify the speed of conductivity based on total water in the body which correlates to body fat percentage. Monitoring body composition in athletes is beneficial for a multitude of reasons. ADP is based on the same principles as the gold standard method of hydrostatic weighing , but through a densitometric technique that uses air . The major claim of the device is that air displacement plethysmography determines the volume of a patient by measuring the amount of air displaced when the patient sits in an enclosed chamber. Influence of subject presentation on interpretation of body composition change after 6 months of self-selected training and diet in athletic males. double layer).
