Body fat calculator machine7/6/2023 ![]() These technologies utilize laser capture technology to measure anthropometrics and estimate body composition. 3D Body Scan: A new, emerging technology that is becoming more readily available are three-dimensional (3D) body scans.It is roughly similar in terms of accuracy as hydrostatic weighing (hydrostatic weighing is slightly more accurate) but is substantially cheaper and easier to perform. However, instead of displacing water, this method displaces air. Air-Displacement Plethysmography: Air-displacement plethysmography utilizes a similar principle as hydrostatic weighing, displacement.Research grade devices can have error rates as low as 5%. However, many of the low-cost commercial models are imprecise with large error rates (greater than 10%). This method is very readily available as it can be put into handheld devices and even at home digital weight scales. Bioelectrical Impedance: Bioelectrical impedance analysis, often referred to as BIA, utilizes electrical currents to assess body composition based on how electrical currents flow through the body.For most people, this form of body composition assessment is impractical. However, this approach is expensive and requires very specialized equipment and training. Hydrostatic Weighing: Hydrostatic weighing, also known as underwater weighing, is one of the more accurate forms of body composition assessment with error rates being between 2-5% for most apparatuses.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. ![]() More specifically things such as waist-to-hip ratios, waist-to-height ratios, and neck circumferences are ways to estimate body composition.
