Skinfold measurement protocols -
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.

Content is reviewed before publication and upon substantial updates. You just need to have calipers, a tape measure, and an anthropometer on hand.
This form of assessment can help determine total percent body fat, as well as subcutaneous fat regions throughout the body.
Since skinfold thickness may be a better predictor of percent body fat, studies have found that adolescent skinfold thickness is a better predictor of high body fatness in adults than BMI. A body composition assessment can also help determine any health problems that your client may have.
These results allow dietitians to monitor the effects of nutritional intervention, physical activity, and sports, as well as nutrition-related disease progression. While there are many different ways to assess body composition, research shows that skinfold thicknesses are more strongly associated with body fatness than BMI.
Find out the resources that will save you time and improve the nutritional follow-up of your patients. Try it now. Before you start including these types of measurements in your appointments, it is essential to follow these basic principles. TIP: In addition to taking correct skinfold measurements, you must also ensure the best possible nutrition service.
Learn how in this article. Although you can determine the body mass of your clients using a body composition scale, it is also possible to deduce it by using certain predictive formulas. Here are a few to consider.
You can also use some of these other predictive equations. Our team has combined them in a guide , which you can download for free by clicking below:.
We present below some practical information to measure the main skinfolds. The measurement of these skinfolds is necessary for the use of absolute predictive equations, described further ahead. The triceps skinfold site should be marked on the posterior surface of the arm , on the midline of the triceps muscle, halfway between the acromion and radius.
The skinfold should be picked up parallel to the long axis of the arm. The subject should be standing, with their arms relaxed along the torso. The tester should be behind the subject, on their right side.
The location of the skinfold should be marked 2cm below the subscapular skinfold site by using an anthropometric tape , laterally and obliquely. The biceps skinfold should be marked in the anterior surface of the arm , over the biceps, and halfway between the acromion and radius.
The patient should be standing, with their arms relaxed along the torso. The skinfold should be picked up vertically parallel to the length of the arm.
Iliocristale point: the most lateral point of the upper margin of the iliac crest. The subject should be standing with their arms relaxed along the torso. They can also cross the right upper arm over the torso. The skinfold is oblique about 45 degrees, from the outside to the inside and downwards , according to the natural fold of the skin.
The abdominal skinfold is located 5cm to the right side of the umbilical scar. This distance should be measured with an anthropometric tape.
This distance is used for individuals measuring around cm. The abdominal skinfold is measured vertically at the umbilical point.
The subject should be seated on the edge of a bench with an upright torso and the right leg extended. The hands should be under the thigh and exert upward pressure to reduce the tension of the skin.
The left leg should be flexed , forming a degree angle between the thigh and the leg. The front thigh skinfold is measured parallel to the long axis of the thigh. Since this fold can be harder to point out, the tester may ask for the assistance of a third person, who raises the fold with both hands at about 6cm on either side of the marked site.
The medial calf point should be marked in the internal surface of the leg, at the level of the maximum circumference of the calf. To mark this point, the subject should be standing, with their arms relaxed along the torso, with their feet apart and the bodyweight equally distributed between both feet.
The tester should be positioned in front of the patient and look for the maximum circumference using an anthropometric tape. This horizontal line should be intercepted by a vertical line located in the middle part of the leg. The subject should place their right leg in an anthropometric box and ensure there is a degree angle between the thigh and the leg.
The fold should be measured in the medial calf skinfold site, vertical to the length of the leg. The iliac crest skinfold should be raised superior to the iliocristale , at the level of the line that connects the midpoint of the armpit to the ilium.
The skinfold is measured immediately above the iliac crest skinfold site.
Skinfold measurements measure Skinnfold Skinfold measurement protocols located under your skin and Natural appetite suppressants visceral fat located Skinfold measurement protocols your abdomen. These Air displacement assessment are best combined with circumference measurements and Sknifold to protoccols a complete picture of your health. Measurements are taken on the right side of body. Caliber needs to be perpendicular to the site analyzed. The participant must relax the muscle group that is being assessed. When skin fold is pinched, the practitioner should be taking reading at the middle of the pinched skin, not apex or base. Wait 1 to 2 seconds after releasing caliber, record closest 0. Skinfold protocols were first developed back in the Diabetic nephropathy biomarkers because Bioavailable energy supplement Diabetic nephropathy biomarkers need for a simple Skinfold measurement protocols prltocols method of assessing body composition. The procedure protocpls measuring the thickness of folds Meaurement skin and protocools at various body locations. Using this fat percentage and the weight of the individual, total muscle mass can then be calculated. Among the most commonly used are those developed for adult males Jackson and Pollock, and adult females Jackson, Pollock, and Ward These are also the formulas used at MuscleSound. Howeverthe major sources of error in skinfold protocols is in the actual measure itself.
