Skin Fold Measurements

Skinfold measurement accuracy -

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.

Beam JR, Szymanski DJ. Validity of 2 skinfold calipers in estimating percent body fat of college-aged men and women. J Strength Cond Res. 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 aged , according 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 time , etc. 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. It should not be used for medical advice, diagnosis or treatment.

As always, you should consult with your healthcare provider about your specific health needs. How reliable is skin fold analysis? Mike Fantigrassi on behalf of National Academy of Sports Medicine.

National Academy of Sports Medicine. Calculations have been created to estimate body fat percentage based on skin fold measurements to the same accuracy as hydrostatic weighing. The calculations and calipers themselves are very accurate. However, it has been found that skin fold measurements may be less accurate for larger individuals, where it is more difficult to separate muscle and fat by a simple pinch.
