Plethysmography, hydrostatic weighing, and 3D body scanning technology. Most accurate method of estimating body fat percentage, DEXA is roughly equal to air-displacement Use DEXA technology due to the radiographic nature of the equipment. This approach requires very specialized equipment and training, and some-states require licensure to X-rays which can measure differences in density of tissue. Dual Energy X-ray Absorptiometry: Dual Energy X-ray Absorptiometry,Ĭommonly referred to as DEXA (DEXA) utilizes specialized machines that have different types of.Relatively similar accuracy to other measures such as bioelectrical impedance, hydrostatic weighing,Īnd air-displacement plethysmography with error rates between 3-10% depending on the instrument Technology to measure anthropometrics and estimate body composition. Readily available are three-dimensional (3D) body scans. 3D Body Scan: A new, emerging technology that is becoming more.(hydrostatic weighing is slightly more accurate) but is substantially cheaper and easier to perform. It is roughly similar in terms of accuracy as hydrostatic weighing Utilizes a similar principle as hydrostatic weighing, displacement. Air-Displacement Plethysmography: Air-displacement plethysmography. Research grade devices can have error rates as Imprecise with large error rates (greater than 10%). However, many of the low-cost commercial models are This method is very readily available as it can be put into handheldĭevices and even at home digital weight scales. Referred to as BIA, utilizes electrical currents to assess body composition based on how electricalĬurrents flow through the body. Bioelectrical Impedance: Bioelectrical impedance analysis, often.For most people, this form of body composition assessment is However, this approach is expensive and requires very Rates being between 2-5% for most apparatuses. Underwater weighing, is one of the more accurate forms of body composition assessment with error Hydrostatic Weighing: Hydrostatic weighing, also known as.Interestingly, waist to weight ratio appears to be the most accurate (Dong et al., 2018). There are good data to show how well different measures correlate to body fat percentages. Things such as waist-to-hip ratios, waist-to-height ratios, and neck circumferences are ways to Method of estimating body composition is through measuring body circumference. Body Circumference: Another very accessible and easy to perform.While easy to perform, this method requires a substantial amount of training and has a pretty highĮrror rate, with up to 10-15% error rates reported in some studies. This method relies on precisely built andĬalibrated calipers that measure skin thickness in millimeters. This layer is known as the subcutaneous fat layer. Skinfold Calipers: One of the most readily accessible ways toĮstimate body fat is to measure the physical thickness of the adipose (fat) layer directly under the.Each method has pros and cons and different levels of accuracy. Technologies, ranging from very simple (a tape measure) to very complicated (three-dimensional laser As mentioned earlier, there are many ways to estimate body fat.
