In terms of health effects, excess fat can add stress to the joints, and cause postural problems. It is also linked to heart disease, stroke, diabetes and cancer.

Measuring body-fat is important for several reasons. To gain an indication of how much fat ones body is composed of serves as a starting point for a weight-loss program. In fact, measuring body-fat regularly can serve to motivate and help an individual make any necessary modifications to their program.

The most common fats in out body are the triglycerides. These come from oils, butter and other natural sources. Lipids are also the body's most concentrated source of energy, yielding around nine calories per gram as opposed to protein and carbohydrate, which contain about four.

Lipids are stored as droplets in fats cells. Calipers work by pulling subcutaneous fat fat directly under the skin away from the muscle with the tongs situated at their ends. Several predetermined sites are measured by a gauge that records the thickness of the pinch created by the tongs. An equation can be used to determine body-fat percentage, or the skin-fold thicknesses, on their own, can be used to gauge progress.

The caliper testing method of body-fat measurement works on the notion that percent of total body fat lies under the skin. Abdominal: direction of fold is vertical, and is taken two centimeters to the side of the umbilicus.

Thigh: direction of fold is vertical, and is taken on the anterior aspect of thigh, midway between inguinal crease and proximal border of patella.

Bodyweight should be shifted to the left foot throughout. Waist: direction of fold is diagonal, and is taken above iliac crest along the anterior axillary line. Thigh: direction of fold is vertical, and is taken on anterior aspect of thigh, midway between inguinal crease and proximal border of patella.

After summarizing the measurements taken from the sites listed above, a chart developed by Jackson and Pollock can be referred to, and body-fat percentage can be noted. As mentioned earlier, readings can also be used to measure progress with having to calculate percentage of fat from the aforementioned equation, or any of the other or-so available equations.

It is generally impossible to achieve a body-fat reading of below three-percent. Even under conditions of starvation, the body will maintain a degree of fat to support vital organs essential fat.

It is thought that about three-percent of a man's body-fat is essential. Women need more essential fat for child bearing and other hormone related functions the average woman's essential body-fat is around percent. Essential fat is stored in the bone marrow, around the internal organs, and in the brain and spinal cord.

The average male agedaccording to statistical norms, will hold between percent body-fat. Bodybuilders and other fitness adherents, on the other hand, tend to go much lower, but still generally do not go any lower than four-six-percent to achieve their best conditioning.

The caliper measurement options reviewed below are generally regarded as the best available, as they are easy to use and scientifically tested.

As body-fat measurement technology has progressed, calipers have also improved in a variety of ways. Other types of calipers generally require the services of a qualified professional as they more complex to use, and, as a result, there is a greater possibility for error if self-testing.

The measurement range with these calipers is mm, double that of the Harpenden model. Lafayette's unique skin-fold design also has an adjustable zero-point which allows one to reset the pointer back to zero.

Subject: Natalie Robson. Gender: Female. Age: Height: cms. Weight: 50kg. Results showed a very low percentage of body-fat, according to the universally used Jackson and Pollock table. To gauge the usefulness of calipers as a fitness testing tool, several experts in their respective fields were contacted, and their opinions asked.

With the above in mind, any pair of calipers will work fine. The greatest source of variability comes from how you use the calipers, who takes your measurements, what measurement sites you use you should measure at the same body location s all the timeetc. The more these variables are held constant, the more likely you are to see a change in the variable of interest, your body fat level.

I hope this sheds some useful insight, David. Thanks for considering my opinion! BMI is only a correlate, and not a direct measure, as it does not factor in gender, age and level of muscularity.

A bodybuilder like Lee Priest, for example, would register as obese despite being shredded at 6-percent body-fat, as he is classed as short and he does hold a lot of muscle weight weight is weight as far as the BMI is concerned; it does not discriminate between fat and muscle.

Lee's BMI would be way off the chart, despite low body-fat levels and loads of muscle. Caliper testing is widely recognised as being a superior measure of body-fat compared with BMI testing.

Before submersion in a water tank, one is weighed. Submersion in water occurs next, in which subject is weighed again.

This procedure works on the premise that bone and muscles have a greater density than water, while fat is of a lower density than water. All of this means a person with more lean body mass will weigh more in water than a person with less lean body mass. This person will therefore have a higher body density and a lower body fat percentage.

Once the bodyweight of the subject is taken, the body fat percentage is calculated using a the Siri formula:. Simply because my body fat was not something I was preoccupied with like body measurements. Neither of them factored into the judging criteria on stage, so I simply did not want to waste my energy measuring something that did play a part in what the judge was judging.

I focused on the "Mirror" my entire career. The judges, judged my appearance not my body fat, hence no hang ups on percentages or measurements. Determining approximate body-fat percentage is a very useful way in which to gauge physical progress. Skin-fold calipers have been used for years to help determine body-fat levels, and many trainers and athletes believe they provide an excellent means in which to self assess and monitor.

Losing excess body-fat for health and cosmetic reasons is, in many ways, a great idea. Monitoring ongoing fat-loss is crucial if weight loss goals are to be met, and using calipers may be the best way to do this.

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. 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.

Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. Several dietary and lifestyle changes can help you burn body fat. By taking a double fold of the skin and underlying subcutaneous fat with the skinfold caliper Figure 2 , practitioners measure various specific sites on the body to estimate the average thickness of each site.

With this information, scientists have developed equations that help us estimate the total body fat percentage.

Matiegka was the first to develop equations for predicting body fat percentage from skinfold thickness Since then, numerous equations have been developed Though many equations have been developed in an attempt to improve the measurement accuracy of skinfold calipers, the following equations were developed by Siri These equations are just one example of how this can be done, however, other equations are specifically targeted to gender, age group, and other types of populations e.

Age is always in years. As skinfold calipers are quick, easy-to-use, and very affordable for estimating body fat percentage, they have become more widely used over the years This has happened despite newer techniques such as DEXA , magnetic resonance imaging MRI , computerized tomography CT , and bioelectrical impedance analysis BIA all having been developed One study by Eston et al.

Furthermore, skinfolds tended to under predict body fat percentage as compared to DEXA , revealing that DEXA and skinfold could not be used interchangeably. According to this study, and others 6, 9 , skinfolds may have a significant bias at extremes of body fat and age.

The best use of skinfolds seems to be their raw values i. the summation of all measurement sites in millimetres , rather than their ability to predict total body fat percentage because there are errors associated with the accuracy of the collection of the raw data, and error in assumptions in the final values Raw skinfold data can give us a good idea of the regional fatness, unlike other measures like BMI or circumference measures alone 8, For some populations, such as athletic populations, where the difference of one percentage point of body fat can make a difference in performance, skinfolds are likely more important For overweight or obese populations, taking skinfolds may be of less use, as accuracy and reliability of the skinfold measurements will be harder to repeat as the skinfold thickness increases, so methods like DEXA may be more accurate 5.

Other studies, for example on obese children, have found good agreeance between skinfolds and percent fat measured by DEXA 22 , however, considerations based on the population being measured must be addressed by each case separately.

In anthropometry, technical error of measure TEM is what we refer to the error that occurs when a measurement is taken on the same object more than once, and the values are not the same.

This error is inherent especially when humans are involved in the measurements, due to:. We want to minimise the error in our measurement as much as possible to create the most accurate and reliable measurement possible each time, but all errors cannot usually be removed To minimise these factors, it is best that we control as many factors as possible, and use the same tester, the same location, the same time of day and day of the week, and a consistent schedule throughout the week in training and diet Because we know the error is associated with the measurements, practitioners should always express their measures as a value with the technical error, so that when measuring change over time, we can be more certain of real change versus errors made in measuring.

To calculate the technical error, use the following equations, outlined in a paper by Perini et al. Table 1. Acceptable levels for intra- and inter-evaluator error, according to a beginner Level 1 ISAK versus a skilful anthropometrist Level 4 ISAK Finally, to make measurements of body composition more accurate, ensure the use of predictive body fat percentage equations that best match the demographic of the persons tested.

Generally, the understanding of the use of skinfold calipers and their accuracy is very poor and grossly misunderstood. Given this, our mission was to clarify whether skinfolds are a good method of choice for body composition.

In conclusion, skinfold calipers can be a cost-effective, quick, and relatively accurate measure of body composition over time. While the gold standard for body composition is still cadaver dissection, skinfold measurements can offer information about the relative fatness, the change in body composition over time, and potentially even the health of the individual.

Knowing that increased fat mass is associated with various diseases, and some athletes need specific body fat percentages for optimal performance, it is of importance that fitness professionals measure skinfolds accurately and with the ability to be repeatable, following the ISAK for best results.
