Body composition measurement method -

So although this method is relatively easy there are also quite a few limitations. Air displacement plethysmography measures body composition through a person sitting within an enclosed chamber i.

Bodpod whereby body volume is indirectly measured through measuring the volume of air the body displaces within the chamber.

In other words, the amount of air that you displace when stepping in the chamber is equivalent to your body volume. Volume, in addition to body weight, can then be used to calculate body density, which then allows FM and FFM to be estimated. This technique involves being fully submerged in a tank of water and expelling all air in the lungs whilst underwater weight is measured.

Both bone and muscle have a greater density than water, whereas fat mass has a lower density than water. Therefore, someone with a larger amount of FFM will weigh more in water. Body density is calculated using underwater weight, body weight outside of the water, density of the water and residual volume of the lungs.

The residual volume in the lungs is measured by inhaling helium and measuring the dilution. Estimations of FM and FFM can then be made. This technique is perhaps the most direct and accurate technique to measure body fat, but there are few places that have this facility and it is not a very practical method.

There are a number of techniques that can be used to measure body composition. The technique we should use depends on the goal of the measurement. For example, if we want to know more about bone density, we should use DXA. If we need an accurate measure of body fat, we cannot use skinfold measurements and we should use underwater weighing or DXA.

On the other hand, if we need a practical way to track changes over time, we should consider skinfolds. The different techniques vary in their accuracy and their reliability how reproducible the results are if you do several measurements.

This will be discussed in the next blog. Wang ZM, Pierson RN Jr, Heymsfield SB. The five-level model: a new approach to organizing body-composition research.

Electrical currents move through muscle easier than fat due to the higher water content of muscle BIA devices work by sending small electrical currents through your body to see how easily they travel through your tissues. Many different devices are available, although advanced devices produce more accurate results.

BIS and BIA devices look similar but use different technology. BIS uses a much larger number of electrical currents than BIA, in addition to high and low frequencies, to mathematically predict your amount of body fluid BIS also analyzes the information differently, and some researchers believe that BIS is more accurate than BIA 14 , However, similar to BIA, BIS uses the body fluid information it gathers to predict your body composition based on equations The accuracy of both of these methods depends on how similar you are to the people for whom these equations were developed However, BIS uses more electrical currents and processes the information differently.

However, while BIA and BIS send currents through your whole body, EIM sends currents through smaller regions of your body These devices are placed on different parts of the body to estimate the body fat of those specific areas Because this device is placed directly on specific body regions, it has some similarities to skinfold calipers, although the technologies are very different.

EIM injects electrical currents into small body regions. Portable devices are placed directly on different body parts to estimate the body fat percentage at those locations. More research is needed to establish the accuracy of this method.

For some devices, you stand on a rotating platform for several minutes while the sensors detect your body shape. Other devices use sensors that rotate around your body. In this way, 3-D body scanners are similar to circumference measurements.

However, a greater amount of information is provided by a 3-D scanner The method uses information about your body shape to predict your body fat percentage. More information is needed about the accuracy of these methods.

Multi-compartment models are considered to be the most accurate method of body composition assessment 3 , These models split the body into three or more parts.

The most common assessments are called 3-compartment and 4-compartment models. These models require multiple tests to get estimates of body mass, body volume, body water and bone content For example, hydrostatic weighing or ADP can provide body volume, BIS or BIA can provide body water and DXA can measure bone content.

Information from each of these methods is combined to build a more complete picture of the body and obtain the most accurate body fat percentage 21 , However, they involve multiple tests and are not typically available to the general public.

Some methods, such as skinfold measurements, circumference calculations and portable BIA devices, are inexpensive and allow you to be measured in your own home as frequently as you like.

The devices can also be purchased online easily, such as on Amazon. Most of the methods with highest accuracies are not available to use in your own home.

If you want a more accurate assessment and are willing to pay for it, you could pursue a method with good accuracy like hydrostatic weighing, ADP or DXA. Ideally, you should do the test before you have anything to drink, especially for methods that rely on electrical signals like BIA, BIS and EIM.

Assessing yourself the same way each time will reduce error rates and make it easier to tell if you are making progress.

However, you should always interpret your results from any method with caution. Even the best methods are not perfect and only give you an estimate of your true body fat.

Body composition is the term used in the fitness and health community to refer to the percentage of fat, water, bone, muscle, skin, and other lean tissues that make up the body. Typically, people break body composition into two groups: fat mass and fat-free mass.
