The Body fat calipers accuracy should then be placed on the skinfold about rat eighth of an inch above your fingers. Use your dominant thumb to press the caliper arm until it is fully depressed. On such models as the AccuMeasure calipers, there is a notch in the main frame of the caliper that the bulbous end of the arm slots into.
When it is all the way in, then you know that you are squeezing with the right intensity. For the most accurate results, you should take three readings at each site and then average them to get your final reading for that site. The first testing site is on the chest, midway between the nipple and armpit.
Stand side on to the person being tested and pinch vertically on that angle between the armpit and the nipple. The second testing site is the abdomen. The position of testing should be about an inch to either the left or the right of the belly button.
Grab between the forefinger and thumb, being sure to include all of the subcutaneous fat that is covering the abdominals. The third testing site for men is the subscapular, which is located directly below the shoulder blade.
Take hold of the skinfold at a degree angle and measure on the same angle. The fourth testing site for men is the front of the thigh. The position should be in the middle of the thigh, halfway between the hip and the knee.
When it comes to testing women, there are a couple of differences. Rather than measuring the chest, you will find a spot on the triceps to measure. Take a vertical pinch midway between the shoulder and the elbow. Rather than measuring the abdomen for women, you should take the measurement directly above the iliac crest.
This is slightly to the front of the hip bone on a slight angle. Take a pinch in that position on a slight downward angle. Women will be tested on the mid thigh in the same position as men and on the subscapular. Once you have taken three recordings at each of the four body positions and worked out the average for each, you should total the four numbers.

| Join Our Mailing List | Müller et al. The greatest difficulties with ultrasound measurements occur when determining the fat-muscle transition, especially when a deep fat layer is present Hoyos et al. This can be particularly important in areas with unevenly distributed fat layers such as the gluteal femoral, abdominal, and paralumbar areas Breathing also affects abdominal SFT measurements, so special caution is required there also In conclusion, with increasing SFT, the absolute scatter for US increases, but the relative deviation remains constant. MRI and US showed very good to excellent reliability except for field 2 0. US measures were systematically higher than MRI. Additionally, the narrow space in the MRI device can also affect the results, particularly when the arms must be hold very close to the body and the fat layer is moved. As Störchel et al. MRI TI vs. US showed an ICC of 0. Mechelli et al. Except for field 2 and 15, both methods show a good reliability at mid front thigh and mid lateral thigh see Table 2. The apparent difference in field 15 2. To investigate the theory, the participant produced a skinfold in field 15 in supine position, because the caliper itself is incompatible with the magnetic field. Although individual hand pressures of skinfolds vary, MRI SI data resembled the Caliper values 1. Considering the US and transversal MRI TI image Fig. There are of course differences, depending on gender, amount of body fat, its distribution and location Female participants are much more likely to present a thicker fat layer in the abdomen up to the umbilicus than is detected in most of the inferior area If the DFL is not incorporated within the caliper at that area, both layers must be relocatable. Lancerotto et al. They found that the SFL consists of large fat lobes organized in single or multiple layers. Fibrous septa encased the fat lobes like in a honeycomb, and were positioned consistently and perpendicularly to the dermis. On the contrary, they found that the DFL consists of fat lobes being smaller and arranged in a less well-structured pattern The fibrous septa, however, are more obliquely-horizontally aligned, and there are few elastic components. Lateral displacement was easily realized, but the original position was inconsistently regained. This appears to clarify the displacement of SFL and DFLs when taking caliper measurements. Similarly, thigh and gluteal areas also possess these two layers, a factor that needs to be considered when using a caliper The two devices were equivalent only in the lower medial and lateral back. Caliper measures Higher SFT values for US were already measured by Kuczmarski et al. Akyer et al. The compression of skin and fat tissue can result in lower measured values Determining the fat-muscle transition becomes difficult also when fibrous structures are embedded in the muscle. Concerning the ISAK, in this study we found that only the subscapular area and anterior thigh proved to show good to excellent reliability in caliper-to-US comparisons. While taking these measurements, we noticed that the caliper and US skinfold values differed tremendously at certain parts of the body. Therefore, which sites function equivalently must be clearly defined, especially when body-fat analyses are relying on caliper measurements. Compression seems to play some kind of a role in such differences between these methods as the caliper compresses fat tissue more than US does. The abdomen area especially field 15 showed a Measurement-value deviations differ in only one direction despite including a wide range of body types. Due to the non-inclusion of the DFL into the caliper at the abdominal area, sites consisting of a double layer should be interpreted with caution. To ensure comparability among studies, a standardized protocol should be adopted that relies on both reliability and validity data for statistical analyses i. ICC, coefficient of variance. This mapping method of ours includes 56 measuring points conceived as specific landmarks. Note that the measurements were taken in one session relying on previous markings. Even if the labeling process revealed no mean differences between observers, it can still affect the variance. Since the body is rather cone-shaped, rectangles are arranged somewhat inhomogeneously. Furthermore, a standard routine for taking ultrasound and caliper measurements is imperative to ensure reliability. Such examinations should only be conducted by experienced sonographers. Handling these instruments requires adequate qualification. Furthermore, the ISAK sites we relied on were not pinpointed, but were nevertheless incorporated within the measurement area. These results allow only a statement for the included study population. For validity conclusions, a higher sample size is required. As measuring subcutaneous fat via US or caliper yields significant differences at most areas, the two methods are not interchangeable. Caliper drastically underestimates the depth of subcutaneous fat tissue depending on its location. Both measurement methods yield very good intrarater data and relative changes can be identified. In direct comparisons, the lower medial and lateral back deliver equivalent results. Regarding ISAK skinfolds, the Iliac crest, subscapular and thigh can be measured interchangeably and equally reliably via caliper or US. The calf, on the contrary, is only measured reliably via US. However, to obtain accurate SFT depth measurements, ultrasound is the method of preference as it captures all fat layers most precisely. When compared to MRI, US is more readily available in the daily practice, although both methods yield similar results. Subcutaneous fat tissues consisting of a double fat layer like the abdomen must be examined with particular caution, when measuring with a caliper, as it does not measure both fat layers.

Abstract Caliper and ultrasound US are used to measure subcutaneous fat tissue depth SFT and then to calculate total body fat. Introduction Body composition is highly relevant when assessing health and nutritional condition 1. This is the first study to measure skinfolds via systematic body mapping by US and caliper. Participants This study included 54 participants aged Table 1 Anthropometric data. Full size table. Figure 1. Body Mapping landmarks. Full size image. Results We evaluated 53 participants for caliper and 54 for US measurements applying our mapping method. Figure 2. Table 2 SFT depth comparison of MRI, US and Caliper at 4 sites. 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.

| 3D Body Scanners vs. Body Fat Calipers Which is Better | Thirty four participants from the total MRI sample were evaluated. The MRI images contain two measurements: 1 native, transversal image MRI TI to show the mean value of the subcutaneous fat depth Fig. Field 15 a : MRI sagittal slice SI of lower abdomen when subject held skinfold to explain the difference between US and caliper SFT values. b : US image measured with a 12 Hz probe showing a 4. c : MRI transversal image shows the pellet marked at field The line illustrates SFT depth. The interrater reliability at 8 standardized sites of ISAK is shown in Table 4. For two dimensional SFT thickness measurements US is comparable to MRI measurement. Wagner et al. Measurements were taken on the chest, abdomen, and thigh in the men, and on the triceps, upper thigh, and suprailiac in the women. ICC values of 0. Pérez-Chirinos Buxade et al. Two raters took measurements at the triceps, subscapular, biceps, iliac crest, supraspinal, abdominal, front thigh and medial calf Another study achieved similar results at eight sites, namely the upper abdomen, lower abdomen, erector spinae, distal triceps, brachioradialis, lateral thigh, front thigh and medial calf However, their Spearman correlation coefficient ρ amounted to 0. Weiss 19 investigated the intrarater reliability of B-mode ultrasound in 30 college students. Images were taken at clearly defined locations on the front and back of the right thigh. Chandler et al. When measuring total SFT, US exhibited smaller overall intrarater differences although it is particularly sensitive since it measures quite punctiformly, while caliper captures a larger area. Disparities may arise by more or less compression or greater fat fluctuations within a field. As a result, both methods identify changes in fat distribution in sites when determined by the same observer. Regarding the caliper, 42 sites showed a good ICC above 0. The posterior thigh and calf tended especially toward poor to moderate reliability. Kispert and Merrifield 21 measured sites in male triceps, chest, and subscapular and female participants triceps, abdomen, and iliac crest. However, we only analyzed statistics of the entire cohort. The ISAK considers 8 sites as standard: biceps, triceps, iliac crest, subscapular, supraspinale, calf, front thigh and abdominal According to our results, six ISAK sites were very reliable; only the abdominal and medial calf revealed moderate to poor caliper reliability. Hume and Marfell-Jones 22 obtained similar findings, but considered the biceps and triceps also as critical, which we could not confirm in this study. Gonzáles-Ruíz et al. Durnin and Womersley 7 reported more variability in measured values in persons with a higher percentage of body fat. Their finding is evidence of many skinfold formulas, especially considering the relationship between subcutaneous fat and body fat mass. All ISAK sites revealed good to excellent interrater reliability. Müller et al. The greatest difficulties with ultrasound measurements occur when determining the fat-muscle transition, especially when a deep fat layer is present Hoyos et al. This can be particularly important in areas with unevenly distributed fat layers such as the gluteal femoral, abdominal, and paralumbar areas Breathing also affects abdominal SFT measurements, so special caution is required there also In conclusion, with increasing SFT, the absolute scatter for US increases, but the relative deviation remains constant.

A study found that the BIA method of measuring body composition is accurate when using standard, published mathematical formulas. However, the body fat scale that the researchers tested did not use accurate formulas to estimate BFP. Therefore, it produced inaccurate estimates. Also in , Consumer Reports conducted a test of six different body fat scales. First, the researchers used a lab-based machine called a Bod Pod to take accurate body fat measurements. They then compared these results with the data that they retrieved from the home-use BIA body fat scales. In this study, the home-use body fat scales either overestimated or underestimated BFPs. The primary advantage of using body fat scales at home is convenience. The scales are easy and safe to use. Also, as long as the scales are consistent in their measurements — even if these are inaccurate — they can help the person roughly track the effectiveness of their exercise regimen or diet over time. However, body fat scales are not an accurate method for estimating BFP. According to doctors , they typically overestimate or underestimate BFP by a large amount. For instance, a study found an association between increased abdominal fat and a higher risk of developing cardiovascular disease. According to the Centers for Disease Control and Prevention CDC , BMI is a good tool for screening whether a person is underweight or overweight. However, it does not measure body fat directly. Exercise can help a person lose fat and gain muscle. A person could use both BFP values and BMI values to help guide their dietary and exercise choices. If either value is higher than average, a person should see their doctor. Higher values could indicate an increased risk of cardiovascular disease. A person can use several different methods to estimate their BFP. Typically, the most expensive options provide the most accurate estimates. Calipers are tools that measure the distance between two sides of an object. A person can use calipers to measure the thickness of skin folds on different parts of the body. The accuracy of caliper measurements depends on the experience of the person using them. Handheld BIA devices use electrical impulses to estimate BFP. As with step-on body fat scales, they are not very accurate. The following body fat measurement tools require special machinery and provide much more accurate results:. A person sits inside the Bod Pod, which uses highly accurate scales to measure their weight. A Bod Pod requires specially trained operators, who tend only to use it in research laboratories. As with the Bod Pod, HUW is typically only available in research laboratories and university settings. However, they may provide a rough idea of how much fat a person has in their body. If either value is high, a person should see their doctor for a health check. The doctor can also provide advice on diet and exercise. There are various ways to measure the percentage of body fat, and some are more high tech than others. In this article, we describe the range of…. When is the best time for a person to weigh themselves? Here, find out the best and worst times to weigh in and how to measure weight accurately at…. Body fat scales can be an easy way to track body composition, but research debates their accuracy. Here, learn about body fat scales and the best…. Sustainable weight management involves eating a balanced diet, exercising regularly, and engaging in stress-reducing techniques. Learn more. Pannus stomach occurs when excess skin and fat hang down from the abdomen. Pregnancy and weight loss can cause pannus stomach. |
| Quick Tips for Improving Body Fat Caliper Accuracy | Caliper measurements are the best way to measure body fat. Anatomy 8 , 2—6. The MRI is considered as gold standard for body fat content and its distribution 5. The greatest difficulties with ultrasound measurements occur when determining the fat-muscle transition, especially when a deep fat layer is present Male body types are often divided into three types, determined by factors like limb proportions, weight, height, and body fat distribution. Obviously there are more differences than just age…. |
| The 10 Best Ways to Measure Your Body Fat Percentage | 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. Portable devices are placed directly on different body parts to estimate the body fat percentage at those locations. Even the most experienced scientific researchers take their time to measure with a ruler then mark with a felt pen each and every location. However, a greater amount of information is provided by a 3-D scanner Fat that lies directly beneath the skin is typically the type that people want to trim down.
