Kushner RF, Gudivaka Composihion, Scholler DA. This Body composition analysis technique makes BIA difficult for techmique or gym-goers who are Boyd for the most optimal body composition results. We all love lying down and relaxing while being assessed. is followed as strictly as possible see reference 2 for details. Methods of Body Composition Assessment.

Body composition analysis technique -

Of these methods, one that is both accurate and practical is skinfold measurement. The measurements are taken with calipers, which gauge the skinfold thickness in millimeters of areas where fat typically accumulates i.

Once the measurements are recorded, the numbers are inserted into an equation that calculates a body fat percentage and alternatively body lean mass. Skinfold is a preferred method of body fat measurement for non-clinical settings because it is easy to administer with proven accuracy and is not obtrusive with regards to the patient.

It also provides much more data than just the final composition measurement - it also yields the thickness of many sites, which can be used as bases of comparison with future results.

For example, an abdominal skinfold improvement from 35mm to 24mm would show a significant improvement in that site even if the overall body fat percentage may have only reduced minimally. BMI is often mistaken as measurable guide to body fat.

However, BMI is simply a weight to height ratio. It is a tool for indicating weight status in adults and general health in large populations.

BMI correlates mildly with body fat but when used in conjunction with a body fat measurement gives a very accurate presentation of your current weight status. With that being said, an elevated BMI above 30 significantly increases your risk of developing long-term and disabling conditions such as hypertension, diabetes mellitus, gallstones, stroke, osteoarthritis, and some forms of cancer.

For adults over 20 years old, BMI typically falls into one of the above categories see table above.

UC Davis Health Sports Medicine Learning Center Body Composition. Body composition. Fundamentals With respect to health and fitness, body composition is used to describe the percentages of fat, bone and muscle in human bodies.

DXA body composition analysis Dual X-ray Absorptiometry DXA is a quick and pain free scan that can tell you a lot about your body. Composition analysis available. Example analysis from a DXA scan PDF Fat: function, metabolism and storage Although body fat endures a negative reputation, fats and lipids play critical roles in the overall functioning of the body, such as in digestion and energy metabolism.

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. Like calipers and the circumference methods, 3D body scanners body surface imaging technology are the most direct ways to measure body fat that you can have without taking an MRI.

However, not all body scanners are built the same. Therefore, be careful and ensure that the digital tape measurements your body scanner of choice uses are precise and accurate. An individual stands on a rotating platform with arms stretched out and hands in fists.

The scan takes about 40 seconds one full rotation while a 3D image of the individual is being rendered. Using non-invasive 3D cameras, body scanning captures surface data of an individual and renders an exact 3D model. This is accomplished with harmless infrared light that reflects off the whole body but is invisible to the eye.

Digital measurements on the body's surface are then taken that replicate a tape measure but are without the imprecision of human sizes. Additional measurements, such as volume and surface area, can be calculated as well from the 3D model.

These measurements are then used to calculate body composition. The research is so promising that the NIH just approved a multi-million-dollar grant to two prominent body composition institutions to further investigate these body scanners, with the goal of commercial viability and dependability as a major motivation.

Pros: The 3D Scanner is easily transportable and, like BIA, only takes a short amount of time. The 3D visuals are extremely engaging and become a great conversation starter.

Many gyms will use 3D body scanning as a customer acquisition tool to demonstrate the sophistication of their services. That's especially important if their total body weight is not changing, but their shape is transforming.

Cons: Because 3D body scanning uses a non-invasive and surface-only camera, individuals wearing baggy or loose-fitting clothing will not elicit precise results. Therefore, subjects must wear form-fitting clothing. Men, however, don't usually own compression shorts. User Experience: It definitely ranks high on the "personal space" scale as users do not have to be touched.

Also, we love the quick assessment time and ability to see the body composition output in 3D form. Those who are self-conscious about putting on revealing or tight clothing may feel uncomfortable rotating on a platform.

Nonetheless, it is essential to establish your own atmosphere. ROI: 3D images speak louder than numbers and are a great way to engage and retain members.

It is an awesome value-add for PT and wellness services. Bottom Line: Great innovative technology with precise results. It has the power to be an assessment tool and a sales and retention device. It is much easier to control for clothing requirements to get precise results than having to control for hydration with BIA or ADP.

So, there you have it! All the necessary information to make an informed and insightful decision regarding body composition measurement. Remember these, and you should be well on your way to a more effective and rich measuring experience.

Updated February Body composition is a term used to describe the percentage of fat and muscle in your body. What is Body Composition and Body Fat Percentage? Skin Calipers We all know this one. How it works: Using the caliper's tong-like features to pinch the skin in specific places, a licensed professional recommended or individual will record the relative thickness of the skin fold.

Bottom line : Look elsewhere. It's time to invest in some technology. Our Grade: D- 2. The Science: The US Navy or circumference method relies on running specific body measurements through a highly developed formula to produce body fat percentage. How it works: Body measurements are taken manually at the designated body parts with measuring tape.

ROI: A powerful method, but not much ROI if you measure incorrectly. Grade: C 3. Hydrostatic Weighing: Commonly referred to as the "dunk tank", this is another old-school method for measuring entire body composition. How it works: An individual is weighed on dry land and then is asked to sit submerged entirely underwater.

The Science: 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.

Grade: B 4. Air Displacement Plethysmography Method ADP With ADP, it is important to breathe literally and not be intimidated by the name! How it works: An individual enters a small chamber-like structure.

The Science: ADP uses one's body mass and volume to gauge body density. Grade: B- 5. Bioelectrical Impedance Analysis BIA Bioelectrical impedance BIA puts the buzz in body composition measurements with internal electrical calculations.

How it works: An individual stands on a platform and wraps their hands around the two available handles. The Science: Bioelectrical impedance runs a small current of electricity through the whole body to gauge body composition.

Dual-energy X-ray absorptiometry DXA or DEXA Aside from sounding like a character from X-men, the DEXA scan is definitely a medical standard in measuring body composition.
