Body fat assessment -

The volume of an object is how much space it takes up. Hydrodensitometry involves submerging a person in water and measuring the volume of water that they displace. This displacement indicates body volume.

Following hydrodensitometry, a person can use body mass and volume measurements to calculate body density with an equation. A further equation converts body density into body fat percentage. During ADP, a person sits inside an enclosed device called a Bod Pod.

Scales inside the Bod Pod measure body mass, while air pressure sensors measure the amount of air displaced by the person. The volume of air displaced indicates body volume.

A 3D body scanner uses lasers to create a 3D image of the body. The scanner rotates to take pictures of the body from different angles, and the scan is quick, taking only a few seconds. A computer then combines the individual pictures to form the 3D image. With this image, it is possible to determine body volume.

Dividing body mass by body volume can indicate body density. Below are body fat ranges for males and females, according to the American College of Sports Medicine :. There are various ways to accurately measure body fat percentage.

Some methods are simple and inexpensive, while others are more complicated and costly. Some of these methods, including DEXA scans, hydrodensitometry, and ADP, are only available at specialized facilities. However, a person can estimate their body fat composition at home by other means.

A doctor or personal trainer can offer additional advice on taking accurate body measurements. Body fat scales are devices that estimate the relative percentages of fat and muscle inside the body. Read on to learn about how they work and their…. BMI is one measure of body size. Learn about how to calculate BMI for men, the recommended BMI range, and the limitations of BMI as an indicator of….

Body fat scales can be an easy way to track body composition, but research debates their accuracy. Here, learn about body fat scales and the best…. Sustainable weight management involves eating a balanced diet, exercising regularly, and engaging in stress-reducing techniques.

For female athletes, there are some very immediate consequences of a low body fat level, including a fall in circulating oestrogen levels.

This in turn can lead to a loss of bone mass, causing problems for women in later life through an increased risk of bone fracture. Assessing body fat can be done using the following methodologies: Hydrostatic weighing, skinfold assessment and bio-electrical impedance.

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. For men, the circumferences of the neck and waist are used in this equation. For women, the circumference of the hips is also included 5. Using body circumferences to estimate body fat is quick and easy.

However, the accuracy of this method can vary widely and is not considered an ideal method of measuring body fat percentage. As the name implies, DXA uses X-rays of two different energies to estimate your body fat percentage 6.

During a DXA scan, you lie on your back for approximately 10 minutes while an X-ray scans over you. The amount of radiation from a DXA scan is very low. DXA is also used to assess bone density and provides detailed information about the bone, lean mass and fat in separate body regions arms, legs and torso 8.

DXA is more accurate than many other methods of assessing body fat percentage. This method, also known as underwater weighing or hydrodensitometry, estimates your body composition based on its density 9.

This technique weighs you while submerged under water after exhaling as much air as possible from your lungs. You are also weighed while you are on dry land, and the amount of air left in your lungs after you exhale is estimated or measured.

All of this information is entered into equations to determine the density of your body. Hydrostatic weighing is an accurate way to assess your body fat. Similar to hydrostatic weighing, air displacement plethysmography ADP estimates your body fat percentage based on the density of your body 9.

However, ADP uses air instead of water. The relationship between the volume and pressure of air allows this device to predict the density of your body You sit inside an egg-shaped chamber for several minutes while the pressure of the air inside the chamber is altered.

To obtain accurate measurements, you need to wear skin-tight clothing or a bathing suit during testing. The Bod Pod is the main ADP device currently used. It predicts your body fat with air rather than water.

BIA devices detect how your body responds to small electrical currents. This is done by placing electrodes on your skin. Some electrodes send currents into your body, while others receive the signal after it has passed through your body tissues.

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.
