A Sneak Peek into the Pros and Cons of Hydrostatic Weighing A steep increase observed in the trend of physical awareness amidst people has been the motivating factor in the extensive research on the measurement of body composition. Adverse maternal body composition has been linked to pregnancy complications including gestational diabetes mellitus (GDM). What are the pros and cons of BIA? Bioelectrical impedance analysis (BIA) is a valid method for the assessment of body composition. Handheld BIA devices use electrical impulses to estimate BFP. 4, pp. The study mentioned previously on obese subjects [9] reported that in 12 of the 50 participants, BIA underestimated fat mass by 5kg or more. 2023 Mar 13;12(6):1218. doi: 10.3390/foods12061218. There are different types of BIA devices, but each requires two contact points. A person can use calipers to measure the thickness of skin folds on different parts of the body. Sun, C. R. French, G.

Zhang, Comparison of multifrequency bioelectrical impedance analysis with dual-energy X-ray absorptiometry for assessment of percentage body fat in a large, healthy population, American Journal of Clinical Nutrition, vol. 2022 Dec 9;101(49):e32229. In addition, eating and strenuous exercise 2-4 hours prior to assessment has also previously been shown to decrease impedance; ultimately affecting the accuracy of the measurement [19]. Overview of BIA Bioelectrical Impedance Analysis 1.4: Body Composition and Obesity - Medicine LibreTexts When it is assumed that the hydration factor of the fat-free mass is constant and is not different in the obese state, then fat-free mass and thus body fat can be assessed with bioelectrical impedance. Limitations of the bioelectrical impedance method for the - PubMed Try out our Academy and access our growing library of sports science courses. Keywords: As females typically have a higher proportion of adipose tissue in the gluteal-femoral region [20], it is possible that this would not be represented using hand-held BIA devices. Non-invasive: BI does not require the use of needles, X-rays, or other invasive procedures, making it a relatively safe and painless option. The difference in bioelectrical conductivity between muscle and fat. Body Mass Index (BMI): Pros and Cons - understandcancerin60minutes Most scales measure an estimate of your total fat, muscle, water, and bone in weight and percentage. View this set. Fat is more resistant than muscle or water, so the higher the resistance, the higher the body fat percentage calculation is likely to be. hypohydrated), indicating that even small changes in fluid balance that occur with endurance training may be interpreted as change in body fat content. A 2016 study found that the BIA method of measuring body composition is accurate when using standard, published mathematical formulas. BIA is an alternative to more invasive and expensive methods like dual-energy X-ray absorptiometry, computerized tomography, and magnetic resonance imaging. So there are pros and cons to any method. This is accompanied by the placement of electrode sensors on other regions of the body, like the . Meanwhile, special sensors detect the volume of air that the persons body displaces based on air pressure changes that occur in the Bod Pod. PROS: 1. Bioelectrical impedance analysis (BIA) measures body composition based on the rate at which an electrical current travels through the body.

It's also wise to understand that there is more to health than your body fat percentage or weight, and these scales are only a tool, not a reflection of your general wellness. Only half of the weight measurements were within a 10% margin of error, but over 80% of the height . BIA scales estimate body fat percentage using bioelectrical impedance analysis. Eur J Clin Nutr. Introduction . 4, pp. Little training required for operation. 67, pp. The full-body scanner from the Naked Labs has probably become the most famous body scanner and has been covered by various tech-related websites in the last two years. 502-511, 2001. How much should I weigh for my height and age. The Pros & Cons of Hydrostatic Testing | eHow UK The primary area for future research in this area is clearly the need for validated BIA equations for athletes in a range of sports and with varying body composition. Download PDF. It is important that these equations are validated using a total-body, water-based, four-compartment method, in an attempt to minimise the measurement error that is found when equations are based on the two-compartment model; such as hydrostatic weighing. Federal government websites often end in .gov or .mil.

Based on that rate, a calculation is used to estimate fat-free mass. . 77, pp. You may have seen body fat scales on store shelves or online that use bioelectrical impedance analysis. Pros & cons of body composition measurement tools - M Reed Nutrition The need to standardise eating, exercise, and both acute and chronic hydration changes are clearly important to provide valid body composition estimations. Hydrostatic underwater weighing (HUW) calculates a persons body density and body volume to estimate their body composition. People typically supply this information via a smartphone or other electronic device. Find out more and use our tools to get a better idea of weight, Medical News Today has strict sourcing guidelines and draws only from peer-reviewed studies, academic research institutions, and medical journals and associations. Since your muscles contain mostly water, they have less resistance to this electrical current. The primary issues with BIA are: Sensor Placement The impulse encounters varying levels of resistance or impedance from the different tissues and substances. (2013). Pros: Hydrostatic weighing is an incredibly accurate technique for measuring body composition. Hydrostatic Body Fat Testing: Is it Accurate? | DexaFit BodPod, skinfold, BIA and hydrostatic weighing) BIA assumes that the human body is composed of a series of cylinders, uniform in shape, length, cross-sectional area, and with constant conductivity. The term body composition refers to the relative percentages of fat, muscle, and water inside the body. In choosing BIA equations, it is important to consider the characteristics of the sample in which it has been developed and validated, since, for example, age- and ethnicity-related differences could sensitively affect BIA estimates. It's usually recommended to combine it with other methods to get a more accurate assessment of body composition. 2017;29:591-7. 2. BI is commonly used in combination with other methods such as skinfold thickness measurement, Dual-energy X-ray absorptiometry (DXA) and Hydrostatic Weighing (underwater weighing) to get a more accurate assessment of body composition. It is based on the difference in resistance when an electrical current is conducted through fat or lean components of the body. Therefore, it produced inaccurate estimates. The validity (the agreement between the true value and a measurement value) of body composition is key to determine the precision of BIA measurement, and its suitability for clinical use. After controlling for factors like water density, lungs volume, and body density, you get your body fat percentage calculated. Because many BIA scales offer several features for a reasonable cost and are a quick and easy way to estimate body fat percent, body fat scales that use bioelectrical impedance analysis are a worthwhile investment for consumers who are curious about their body composition. Accessibility Bioelectrical impedance analysis (BIA) is an afford-able, noninvasive, easy-to-operate, portable, and fast (assess-ments can be made within 5-10 min) alternative for assessingsegmental or whole body SM (15, 19, 31, 38, 40) and so maybe a practical method for assessing SM in the elderly, althoughthe technique has not been fully validated in this 443-446, 2004. 2010;8(5):437-441. doi:10.1089/met.2010.0013.

Drinkwater, Gross tissue masses in adult humans- data from 25 dissections, Human Biology, vol. 4, pp. This means that when you use the device, you place each foot on a pad, and the current travels through your body between your feet. Adah is an occupational therapist, working in the area of pediatrics with elementary students with special needs in the schools. Despite being popular in many commercial gyms and within epidemiological research on group body composition, BIA does not appear to provide a valid single- or repeated-measure of body composition for athletes. This is possible simply because different bodily tissues (e.g. Lean tissues are highly-conductive, as they contain large quantities of water. Exhale all the air present inside the lungs and then hold your breath Similarly, athletes often take interest in their body fat percentages, and a false score indicating so-called negative changes in body fat may impact the confidence and compliance of an athlete.
