Skinfold Body Fat Calculator - Om Calculator

The 7-site skinfold calculator is a sophisticated tool used by fitness professionals and researchers to assess body composition and estimate body fat percentage. Unlike simpler methods like BMI or basic body fat scales, the 7-site method provides a more comprehensive assessment by accounting for fat distribution patterns across different body regions. Research has shown this method to be accurate within 1-3% when performed correctly by trained professionals.

Body fatin athletes, there are several measurements that are usually done, namely:Triceps (upper forearm)Biceps (upper forearmSubscapularSuprailiacaSome of these partsare important for measurement. However, do you know how to measure body fat.Correct Body FatMeasurementTo calculate thecorrect body fat, we must calculate the folds on the skin. Why is that?Hopefully with this, it can allow us to estimate the total percentage of fat insuch athletes.The measurement method can be done using the Skinfold Caliper tool, where it can calculate the thickness of the skin, which can later represent how much body fat. The first way of use is that researchers pinch a person’s skin in an appropriate place to remove the double layer of skin and adipose tissue underneath. Then the tool is placed to pinch the part.And you know what, that on the Coast Sport website, it isexplained that fat calculations using skinfold calipers are performed on almostall athletes in all academies and institutes in Australia. It is important toknow how the ideal conditions of athletes in various sports to improve theability to play athletes.Skinfold Caliper asBody Fat Measurement Tool from PT Solo Abadi IndonesiaSolo Abadi as the largest manufacturer of anthropometry and medicaldevices in Indonesia, has a skinfold caliper that can be used to measure skinfolds easily. In addition, we have two types of skinfolds that can be used asfollows : 1. Harpenden Skinfold CaliperMetrisis Harpenden Skinfold Caliper is a measuring instrument used tocalculate the thickness of folds of human body skin. This calculation can beused to estimate the percentage.

Choose the one that best fits your needs and equipment availability.Body Fat Percentage Calculation ResultsYour body fat percentage results will be displayed in charts based on guidelines from the American Council on Exercise (ACE), the World Health Organization (WHO) / National Institutes of Health (NIH), and the American College of Sports Medicine (ACSM).The charts also include a weight column that provides an estimated weight range for each body fat percentage category. This allows you to determine the approximate weight needed to fall into your desired range. However, these estimates assume that any weight gain or loss primarily affects body fat while keeping lean body mass constant. In reality, both lean body mass and fat mass fluctuate, though lean mass tends to change more gradually.To stay on track, it’s advisable to recalculate your body fat percentage periodically, especially as you gain or lose weight. If needed, adjust your target weight accordingly. When following a low-calorie diet, you can help preserve muscle mass by incorporating strength training exercises and increasing protein intake.STAY UP TOP DATEOur latest newsHave Questions?Frequently Asked Questions (FAQ) About Our Body Fat CalculatorWhat is a body fat percentage and why is it important?The body fat percentage indicates the amount of fat tissue in relation to your total body composition.

Measure your body fat percentage. This post will be devoted to the skinfold method.How Skinfold Testing WorksYou store the majority of your fat, rather inconveniently, right on top of your muscles (obscuring the definition), and right below the skin. This is known as subcutaneous fat. You store fat internally as well, but since the majority of your fat is below your skin, you can use skinfold measurements to estimate your overall body fat percentage.The test really is as simple as "pinch an inch." All you need is a skinfold caliper, a vice-like device that pinches the skinfold and measures the thickness in millimeters.After taking one or more measurements at various sites around the body, you can convert that sum of the skin folds into a body fat percentage using a math equation or an easy conversion chart that has already done the math for you. Some electronic calipers have the formulas built in, so they automatically display a body fat percentage right on the digital screen.The purpose of this post is to show you some of the popular skinfold calipers, ranging from expensive professional models that are usually only used by trainers or health clubs, to super cheap plastic calipers that you can use at home.Skinfold Calipers, ReviewedThere are more types of body fat calipers than I have time to review in this post, so what I'll do instead is list the 5 calipers that I have personally used over the years, which also happen to be the most commonly used calipers. This way, I'll be able to speak from experience.I will also explain the pros and cons of specific calipers as well as pros and cons of skinfold testing technique in general - including addressing the common criticisms of body fat testing that lead some people to say, "don't bother" (I disagree... but more on that later). Skyndex CaliperI was first introduced to the SKYNDEX caliper when I was working for Gold's Gym in 1991. For professional use (as a trainer and fat loss coach), it's my caliper of choice for testing other people.The Skyndex is unique among calipers because it's electronic. As you pinch the skinfold, you can see the thickness reading in millimeters on a digital readout. The precision is impressive - it measures the skin folds to the tenth of a millimeter (example 7.3 mm and so on).Some argue that measuring skinfolds to the decimal point is moot, owing to the margin for error inherent in body fat testing. But personally, if a caliper offers that kind of precision, I like it, and I believe other experienced technicians will appreciate it too.You can order the SKYNDEX with two different formulas for adults: The Durnin 4-site formula (bicep, triceps, iliac crest and subscapular) or the Jackson Pollock 3-site formula (abdominal, thigh and pectoral for men or thigh, iliac and tricep for women).Before another art aficionado gets confused or angry, let me assure you, Jackson and Pollock are a couple of researchers who published body fat equations in.

Here are several equations that give a value for body density and percent body fat from skinfold and girth circumference test results, from the research of Dr. Andrew Jackson and M. L. Pollock.
