Body composition analysis technique -
Body mass is combined with a measurement of body volume obtained using instruments called a BOD POD® and a PEA POD®.
Estimates of fat and fat-free mass are generated. ADP offers several advantages over alternative reference methods.
The technique is quick, non-invasive, safe and accommodates a wide range of subject types e. The method does not use radiation as does the DXA , is much faster than a whole-body potassium measurement 2 min vs.
The PEA POD is designed to measure infants up to about 8 kg in weight. The BOD POD, with its pediatric option, can accurately assess body composition of children as small as 12 kg. The BOD POD will also accommodate adults weighing over kg; thus, these instruments are well suited for longitudinal testing of a broad range of subjects.
Both instruments require a small change in pressure in the measurement chamber for a few seconds that is undetectable to the subject. The magnitude of the pressure change is like that experienced when moving on an elevator, at normal speed, between the 3rd floor and ground floor of a building.
HR-pQCT is a non-invasive technique that provides high resolution, quantifiable images of bone, focusing on the extremities.
HR-pQCT can measure volumetric bone density and discriminate between cortical and trabecular bone. In addition, the microstructure of bone can be assessed trabecular bone volume, number of trabeculae per millimeter, inhomogeneity of the network, trabecular thickness, cortical thickness and cortical porosity.
Scan analyses involve segmentation of cortical and trabecular compartments. Analysis results provide bone density measurements trabecular, cortical, and total volumetric , microarchitectural measurements trabecular number, thickness, separation, and cortical thickness and porosity , and morphological outcomes total bone area and cortical area.
The resistance to an applied electric current flowing through the body is related to the volumes of conductive tissues that the current passes through. This measurement can estimate water and fat ratios. Bioelectrical impedance analysis is based on the conductive and non-conductive properties of various biological tissues.
Most of the body's fat-free mass is composed of conductive tissues such as muscle, while fat is part of the non-conductive tissue mass. The volume of these tissues can be estimated from the measurement of the resistance to an applied electric current flowing through the body.
Nonetheless, unlike calipers, there's no pinching involved. However, using the tape measure can be uncomfortable for your member or patient. Sometimes, however, the biggest problem is a lack of repeatability, owing to the difficulty of repeating a location when taking a measurement.
The US Navy or circumference method relies on running specific body measurements through a highly developed formula to produce body fat percentage. These measurements are taken manually at the abdomen and neck for men and women's neck, waist, and hips.
During its research and development stage, this formula was calibrated using data from DEXA scans and, when administered correctly, is said to produce the same amount of accuracy. Body measurements are taken manually at the designated body parts with measuring tape. This measurement process is then repeated three times.
The average of the three-body composition measurements taken at each spot is then input into a formula to calculate the individual's total body composition. Pros: Very easy to use and administer on-site. The formula is highly reliable when done correctly.
Cons: Prone to human error as the method relies on taking measurements manually. Tilt the tape measure slightly, or add a bit of slack, and you'll find extremely varying results. User Experience: Pretty painless experience for most but can be time-consuming.
This approach may not be very pleasant for those who don't want to be touched during an assessment, especially because each measurement must be repeated three times. That's a lot of touching! Bottom Line: The science is sound, but the instrumentation is lacking in sophistication.
If paired with digital circumferences, like those from body scanners, then this method can be the new gold standard, and for that alone, it gets a better grade than skin calipers.
Commonly referred to as the "dunk tank", this is another old-school method for measuring entire body composition. But unless your clients are looking for a deep-sea adventure, then this might not be the best experience for your patients. The body composition results yielded by hydrostatic weighing are pretty accurate.
BUT, the space requirements are impractical. Often, third-party companies will drive around trucks with a dunk tank inside and charge a fee for the assessment. And on top of that, trying to convince members to get wet is not an easy challenge to overcome.
An individual is weighed on dry land and then is asked to sit submerged entirely underwater. The individual will then expel as much air from their lungs while their underwater weight is taken. The underwater weight is then compared to dry land weight and, using a specific formula, determines a person's body composition.
Hydrostatic weighing is based upon the Archimedes Principle , which says that the buoyant force on a submerged object is equal to the weight of the fluid displaced by the thing. In other words, denser material i. Pretty smart, eh? Pros: Hydrostatic weighing is an incredibly accurate technique that yields precise body composition results if done correctly.
Always a plus! Cons: Ah yes, the downsides. The results of hydrostatic weighing may be compromised if an individual does not literally breath out every last breath gah! User Experience: Good for Pisces who loves water, but bad for everyone else who doesn't. ROI: If you and your customers are serious about results, then reaching out to a service that provides hydrostatic weighing is a good investment.
It's a great value that adds to a memorable experience. Bottom Line: Accurate, and not a ton of room for error. But the user experience is not great. Moreover, it's not something you can include in your facility on a permanent basis. There may be better options for you.
With ADP, it is important to breathe literally and not be intimidated by the name! Really, ADP is much like the dunk tank method minus the scuba diver experience and will have you noticing "something in the air". An individual enters a small chamber-like structure. At this time, changes in chamber pressure are recorded to determine body volume.
ADP uses one's body mass and volume to gauge body density. The method uses air instead of water to measure volume. Using those density readings, ADP then calculates the proportions of lean to fat mass i.
Pros: ADP's easily accessible chamber and non-invasive method make it a great option for the more vulnerable communities such as the elderly, children, and those with physical handicaps. Cons: There are many variables including hydration and body temperature that can cloud ADP's body composition results; these variables can make it challenging to receive an accurate reading, especially for the active gym population who are often being tested pre and post-workout.
The last thing we want is for our workouts to interfere with our readings. It's why we're being evaluated in the first place! User Experience: Claustrophobic much? ADP is definitely not good for those who hate enclosed spaces.
However, if you have people willing to "brave the cocoon," the process is pretty straightforward and non-invasive. However, there's also the not-so-fun hair cap you need to wear to get consistent results. ROI: Very accurate, but much better for an academic or medical setting.
You might have more trouble trying to sell it as a value-add in a commercial setting like a health club. Bottom Line: Quite expensive takes a lot of space, but it can be pretty accurate if controlled correctly.
Bioelectrical impedance BIA puts the buzz in body composition measurements with internal electrical calculations. BIA devices are incredibly mobile and can be used in various spaces, which makes them optimal for small gyms or wellness centers.
However, beware of accuracy after chugging that Gatorade post-workout! An individual stands on a platform and wraps their hands around the two available handles.
To get bioelectrical impedance measurements, the individual is asked to hold their breath and relax. At this relaxed state, the BIA device sends a small electrical pulse through the body. For about 20 seconds, tiny electrical impulses run up both legs and arms. Some systems, though, only have arm holds.
Bioelectrical impedance runs a small current of electricity through the whole body to gauge body composition. The method relies on the currents to easily permeate a cell's membrane.
Resistance to the current from water is a function of how hydrated your body is and is correlated with your body fat percentage. Like other methods, BIA doesn't explicitly measure fat, but rather it infers body fat from a direct measurement of something else, which in this case is water.
Pros: The number of total body water TBW is determined using a BIA machine, which is significantly quicker than the DEXA test 15 minutes and repeated "dunks" of hydrostatic weighing. Additionally, the device is easily movable, as the 3D body scanning method.
It is also reasonably simple to run a BIA machine without the assistance of a professional. Cons: Like Air Displacement Plethysmography, variables such as hydration amount can compromise the accuracy and precision of results. This again makes BIA difficult for athletes or gym-goers who are looking for the most optimal body composition results.
In addition, electrical currents also make BIA unsuitable for pregnant and pacemaker populations. User Experience: For those who like a quick and painless process aka all of us , this is a great option. Just don't down that massive electrolyte water before hopping in if you want accurate results!
ROI: Portable. Easy to use. It can be easily monetized as a value-added service. Overall, a great investment. Bottom Line: A great option for mobility, size, and relatively accurate body composition results.
However, be aware of the variables that can skew results and set expectations with members or clients inappropriately. Moreover, there's a big range of devices in this category with a relatively high price tag, so choose wisely.
Aside from sounding like a character from X-men, the DEXA scan is definitely a medical standard in measuring body composition. The DEXA scan exposes patients to minimal amounts of ionizing radiation, which makes it different from other radio waves or ultrasound methods.
The individual lies down on the exam table as the DEXA scanner moves over them. This process takes about 15 minutes, and it is exactly what a cool Sci-Fi movie looks like.
The DEXA duel-energy X-ray absorptiometry scan, originally focused on measuring bone mineral density, is now widely used as a tool to measure body composition as well.
DEXA accomplishes this by running two beams of light over the bone and gauging how much light is absorbed. The denser the material i. This reading is then converted into a body fat percentage.
Pros: Accurate results; measures bone density as well as body composition. It's probably the most well-validated body composition method in the academic world, other than the MRI. DEXA scans you with X-rays, which can be harmful to your health if exposure is too frequent.
User Experience: Let's face it. We all love lying down and relaxing while being assessed. But X-rays are dangerous, and there's some convincing to do to get people scanned. ROI: The most expensive choice on this list might not be the most practical investment for a facility due to its relatively high price tag.
Nonetheless, third-party assessment services are offering DEXA scans as a service, which is becoming more common. Hiring a third party for DEXA scans and building it into your wellness program, fat-loss shred, inch-loss competition, or simply as a general as an added value could be a great way to increase membership sales and retention.
Bottom Line: Amazing medical-grade device and technology. It is not so practical for most gyms and wellness centers given their size, price, and assessment process, but not a bad idea to provide a service to members through a third-party service. We love the way that it engages clients both visually and numerically.
One of the key reasons why body scanning took first place is the fact that it builds on the power of the caliper and circumference methods without human error.
In the world techniique Body composition analysis technique and fitness, body composition assessment Body composition analysis technique techniwue an analysix aspect annalysis helps compossition understand the makeup of our bodies. Natural Resveratrol sources refers to Oral care products proportion of fat, muscle, and other tissues in our bodies and can be a crucial factor in determining our overall health and fitness levels. While there are various methods for measuring body composition, not all are equally accurate or reliable. This article will explore the top body composition assessment techniques in fitness centers. Body composition is an essential component of health and fitness.Body composition analysis technique -
These health complications can include cardiovascular disease , high blood pressure, diabetes, and more. It then makes sense that in a Canadian study of 50, people, it was found that a low BMI did not necessarily correspond with a lower mortality rate.
Hopefully, by now we have convinced you the importance of using something more advanced than a weight scale or BMI. Luckily, there are many methods to determine your body composition. Some are quick and easy but provide basic information only.
Some are lengthy and expensive and require the assistance of a trained technician to administer a test. This is a method that many people have encountered in their local gym. Calipers are widely used because they are portable , easy to use, and can be administered by almost anyone as long as they have had proper training and sufficient experience.
These results are taken and used in mathematical calculations, which determine the fat mass in your entire body. Calipers are an example of 2C body composition analysis. Hydrostatic weighing also known as underwater weighing calculates your body fat percentage using you underwater body weight.
To get your underwater weight, you first need to expel all of the air in your lungs and then submerge yourself in a pool while sitting on a special scale.
Your underwater weight is compared with what you weigh on land, and these numbers, together with the value of the density of the water in the pool, are put through a series of calculations.
These calculations produce your body fat percentage. However, just like calipers, hydrostatic weighing cannot report anything beyond body fat, like skeletal muscle mass, body water, and dry lean mass.
To get a hydrostatic weighing test performed, you will need to make an appointment at a facility such as a university or high-end sports complex that has built a hydrostatic weighing pool and a trained staff.
DEXA sometimes abbreviated as DXA , is a medical test that involves lying on a table while a machine sends X-rays through your body and measures the difference in the amount of energy initially sent through the body and the amount detected after it exits the body.
Although DEXA was originally designed to measure bone density, it is now used to measure body fat and muscle mass. Unlike calipers and underwater weighing, DEXA scans have the ability to measure the body segmentally, scanning each arm and the trunk separately in order to accurately measure fat mass, soft lean mass, and bone density in each segment.
In order to get a DEXA scan performed, you will typically need to make an appointment with a hospital or clinic that has a DEXA device. You may need to do some research; because of the cost, not all hospitals and clinics will have a DEXA machine.
Once impedance is measured, body composition is calculated. Unlike other methods, a technician does not always need to be present at a BIA test, and you can use BIA devices with just by following the directions on the device. BIA devices range widely in quality and accuracy , and you should be aware that not all BIA devices test the entire body.
Consumer body composition scales, use BIA to directly measure leg impedance only and use estimations to determine results for the upper body. Handheld devices only directly measure arm impedance and estimate results for the lower body.
The most advanced BIA devices are even able to perform segmental analysis. Because BIA measures work by measuring body water, a lot of useful information can be reported.
Although nearly all BIA devices will tell you your body fat percentage, some devices can go much further and report the body water weight, skeletal muscle mass, lean body mass, and much more. Hopefully, this helps you a general understanding of body composition.
Your body composition test results can aid you immensely in understanding your weight, improving your overall health, and helping you achieve your fitness goals.

Fat and muscle may weigh the same, but muscle is significantly denser than body fat. The four common methods of measuring your body composition are calipers, hydrostatic weighing, DEXA, and BIA.
What are the 2 components model of body composition? Fat Mass The substance everyone seems to always have too much of and is always doing their best to get rid of.
Fat-Free Mass FFM Fat-Free Mass is what it sounds like — all the mass in your body that is not attributed to fat. What are the 4 components model of body composition?
Minerals Your body contains minerals that are primarily contained in two places: in the bloodstream and inside the bone tissue.
Fat Here are some less common but important body composition terms: Dry Lean Mass DLM : Your Dry Lean Mass is the combination of the weight attributed to the protein and the bone mineral in your body. Lean Body Mass LBM : Your Lean Body Mass is the combination of your DLM and body water.
Skeletal Muscle Mass SMM : Not to be confused with DLM or LBM, Skeletal Muscle Mass are the muscles that are connected to your bones and allow you to move. These are all the muscles that can be grown and developed through exercise your pectorals, biceps, quadriceps, and so on.
How Can You Check Your Body Composition? Here are four common methods: Skinfold Calipers Image Credit: Flickr This is a method that many people have encountered in their local gym.

Dual Energy X-Ray Absorptiometry DEXA. Love 31 Share Tweet Share Pin. POPULAR POSTS. Fitness InBody Blog The Best Leg Workouts, According to Science. This extremely sensitive device measures the gamma rays emitted from an isotope of potassium known as 40K, which exists naturally in the human body at a known natural abundance 0.
This knowledge, plus the fact that potassium is only found inside body cells and is not present in stored triglycerides, makes 40K data an accurate index of the body's total cell mass the active growing tissues in the body , which in turn can be used to estimate fat-free mass.
Although the terms lean body mass LBM and fat free mass FFM are often used interchangeably, it is more accurate to think of body weight mass as the sum of LBM muscles, organs and other non-fat tissues such as bone plus adipose fat tissue; or alternatively, as the sum of extractable fat i.
DXA was originally developed to determine bone mineral density and to aid in the diagnosis and treatment of osteoporosis. Later, the technique was expanded to include the analysis of fat mass and lean body mass in addition to bone mass.
The basic principle of DXA data acquisition is based on the differences between bone and soft tissue attenuation at high and low x-ray levels. As an x-ray beam passes through the subject, detectors register the varying levels of x-rays that are absorbed by the anatomical structures of the subject.
The raw scan data, which includes values of tissue and bone, are captured and sent to a computer. The computer generates an image of the body in pinpoint pixels, which can be 'counted' to assess bone status and fat distribution.
The radiation exposure during DXA scanning is very low. Body mass is combined with a measurement of body volume obtained using instruments called a BOD POD® and a PEA POD®. Estimates of fat and fat-free mass are generated.
ADP offers several advantages over alternative reference methods. The technique is quick, non-invasive, safe and accommodates a wide range of subject types e.

The BOD POD will also accommodate adults weighing over kg; thus, these instruments are well suited for longitudinal testing of a broad range of subjects.
Both instruments require a small change in pressure in the measurement chamber for a few seconds that is undetectable to the subject. The magnitude of the pressure change is like that experienced when moving on an elevator, at normal speed, between the 3rd floor and ground floor of a building.
