Skinfold measurement tools -

There are accreditation courses available through ISAK. advantages: Skinfold measurements are widely utilized to assess body composition. It is a lot simpler than hydrostatic weighing and many of the other body composition techniques.

After the original outlay for calipers, the daily tests costs are minimal. other considerations: some participants may feel uncomfortable stripping down in front of the tester, therefore every effect should be made to make them feel comfortable.

For legal reasons, it is wise to have another person present, and to have females testers for female participants. The right side measurement is standard, though in some situations you may need to test someone on the left side.

If so, you must record this and endeavor to always test on the same side for that person. Reasons for testing on the left side may include injuries, amputation, deformities, or other medical conditions.

Although the organisation has thousands of members and holds itself to a high standard of excellence, professionals in the field of sports science and strength and conditioning are not legally required to hold an ISAK certification to provide anthropometric services.

There are numerous ways to measure body composition, including, but not limited to, body mass index BMI , underwater weighing, dual-energy x-ray absorptiometry DEXA , air-displacement plethysmography, skinfold calipers, or somatotyping.

Currently, the absolute gold standard for body composition measurement is cadaver analysis 2, 21 , as no other in-vivo technique will be as accurate as the dissection technique.

In living subjects in-vivo , however, DEXA is currently seen as the gold standard. In this article, the advantages and shortcomings of the skinfold calipers as a means of estimating body composition will be thoroughly discussed.

Depending on the physiological demands of the sport, anthropometry could be one of the key performance indicators in competition, as it is in sport climbing. Many studies have highlighted the importance of a low percentage of body fat for good climbing performance and therefore is measured routinely in testing batteries In this case, DEXA and skinfolds might be used jointly so that both accurate numbers of actual body fat percentage through DEXA , and more frequent check-ins with an ISAK-certified specialist for skinfolds could be used.

Similarly, a key performance indicator for marathon events or long-distance running is a low body fat percentage, which is crucial in planning the yearly periodisation for the athletes in and out of their main competition seasons 4.

For an event like the marathon, in which the athletes carry their body weight, having a low body fat percentage, and low total body weight will decrease the energy cost of running, further contributing to their performance Skinfold calipers Figure 1 are one instrument used by anthropometrists specialists that study kinanthropometry to attempt to estimate the amount of fat on a human body.

There are many different shapes and prices for skinfold calipers, but ISAK does not specify which caliper types are required, so often what the budget affords are the ones practitioners choose.

Harpendens, by contrast, can cost hundreds of dollars, are made of metal, and have a measurement accuracy to the nearest 0. As long as calipers are properly calibrated, then they may be used for estimating 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.

To do it a caliper is used to pinch body fat and measure its thickness on multiple sites of the body. You need to have experience and skill to perform the test correctly.

The thickness of these folds is a measure of the fat under the skin, also called subcutaneous adipose tissue. Skinfold thickness results rely on formulas that convert these numbers into an estimate of a person's percentage of body fat according to a person's age and gender.

The skinfold measurement test is one of the oldest and most common methods of determining a person's body composition and body fat percentage. This test estimates the percentage of body fat by measuring skinfold thickness at specific locations on the body. Skinfold measurements are generally taken at specific sites on the right side of the body, with the tester pinching the skin at the location site and pulling the fold of skin away from the underlying muscle so only the skin and fat tissue are being held.

Special skinfold calipers are then used to measure the skinfold thickness in millimeters. Two measurements are recorded and averaged. The measurement sites vary depending upon the specific skinfold testing protocol being used, but typically include the following seven locations on the body.

These include the abdomen, midaxilla, pectoral area, quadriceps, subscapular area, suprailiac area, and triceps. Once you have taken skinfold measurements, you'll need to convert these numbers into a percent of body fat. The easiest way to calculate the percent of body fat is to use a software program.

There are as many different formulas and calculations as there are ways to measure skinfold thickness, but some that have held up over time include those published by Jackson and Pollock. You can find these being used in the following online body fat calculators:. If you would like to measure your body fat percentage without requiring any special tools or measurements, you can also try out our calculator:.

The accuracy of these tests may depend on the type of calipers being used, the competence of the tester, and a person's level of hydration at the time of the test.

Since using the calipers can be difficult, skinfold measurements may not be the best choice for assessing fat percentages, especially if you're trying to do it yourself. With other technologies available, skinfold testing is becoming somewhat of an ancient art-form.

Most personal trainers today use electrical impedance methods and scales that measure body composition instead of directly measuring skinfolds. No matter the method you use, it's important to keep in mind that weight fluctuates constantly and most body composition tests should be used as a general reference point and are best when averaged over a given timeframe.
