The Brozek et al and the Siri equations can be used for this step:. Body fat values should be generated from published equations which closely match the study population. It is critical that the equation selected for estimating body fat is appropriate to the demographics of the cohort under investigation e.
race, age, and gender. Durnin Womersley developed general equations from a heterogeneous group of varying ages. Table 1 Durnin Womersley equations for the estimation of body density using 4 skinfold sites. Source [14]. Estimates derived using these equations have been compared to those from the criterion 4-component model see Figures 5 and 6.
Both equations tend to underestimate body fat especially in larger individuals. Similar results have also been observed in men Peterson et al. Source: Peterson et al. However, Slaughter et al. Table 2 lists equations used to determine body composition values in children and adolescents using skinfold measurement.
Table 2 Published equations used to estimate body fat in children and adolescents from skinfolds. Source: Rodriguez et al. Some equations for children and adolescents have been compared with the criterion 4-component model , see Table 3.
Significant bias for percentage body fat and fat free mass was observed for the equations by Slaughter et al. No significant mean bias was shown by the equation by Deurenberg et al.
This may affect the evaluation of body composition changes within individuals overtime. Correlations were calculated as the correlation between the difference and mean.
FFM values were log transformed to express the difference as a percentage of the mean. Values for percentage body fat are expressed as a percentage of body weight. Adapted from: Wells et al. first 10 days of life and based on different skinfold thickness measuring sites.
The Deierlein et al. A non-significant correlation suggests no bias in the technique across the range of fatness. Source: Clauble et al. However, the relationship between total body density and skinfold thickness varies with age and those equations may not be applicable in younger groups.
Estimates derived using the Slaughter et al. Agreement analysis showed significant bias at 6 weeks, underestimating percentage body fat by 2. The agreement analysis between Slaughter et al. Estimates derived from the Deurenberg et al.
When analysing data in infancy, often the raw thickness data are used. The sum of the thicknesses is determined and internal standard deviation score Z-score are derived.
Internal Z-scores can be generated by regressing skinfolds on age and using the saved residuals , and then adjusting for sex in the analyses.
The skinfold indices, triceps skinfold-for-age and subscapular skinfold-for-age are useful additions to the battery of growth standards for assessing childhood obesity in infants between 3 months to 5 years. These indices are expressed in percentiles percentage of median and can be assessed by the percentile point achieved by a child relative to the healthy children of that age and gender in the same population.
Median is regarded as a reference value, and 3 rd and 97 th percentiles as thresholds to indicate abnormally low or abnormally high values. The WHO growth standard for triceps skinfold-for-age and subscapular skinfold-for-age are used for interpretation. Considerations relating to the use of skinfold thickness methods in specific populations are described in Table 6.
To obtain reliable data from this method it is essential to standardize the procedure, train the participating staff and assess inter and intra observer reliability to monitor measurement error. Refer to section: practical considerations for objective anthropometry.

Population specific equations are used to derive estimates of percent body fat. Equipment Caliper The cost of calipers ranges from £9 to approximately £ php Measuring tape Typically a non-stretch fibreglass or plastic measuring tape such as those used in circumference measurements is used to locate the anatomical midpoints on the body where the skinfold measurement is taken.
Protocol Skinfold measurement can be obtained from 2 to 9 different standard anatomical sites around the body using a caliper, as shown in Figure 2. The following are the nine anatomical sites as illustrated in Figure 2 that are most commonly used in the assessment of skinfold thickness: Chest or pectoral skinfold: For men, get a diagonal fold half way between the armpit and the nipple.
Mid-Axillary: A vertical fold on the mid-axillary line which runs directly down from the centre of the armpit. Supra-iliac or flank: A diagonal fold just above the front forward protrusion of the hip bone just above the iliac crest at the midaxillary line. Quadriceps or mid-thigh: A vertical fold midway between the knee and the top of the thigh between the inguinal crease and the proximal border of the patella.
Abdominal: A horizontal fold about 3 cm to the side of the midpoint of the umbilicus and 1 cm below it. Triceps: A vertical fold midway between the acromion process and the olecranon process elbow. Biceps: A vertical pinch mid-biceps at the same level the triceps skinfold was taken.
Subscapular: A diagonal fold just below the inferior angle of the scapula. Medial calf: The foot is placed flat on an elevated surface with the knee flexed at a 90° angle.

Equatiobs measurement is a test that estimates your amount of body fat, which is converted into percentage of total body weight. 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.Skinfold measurement equations -

Any comments, suggestions, or corrections? 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. Beam JR, Szymanski DJ. Validity of 2 skinfold calipers in estimating percent body fat of college-aged men and women.
The significant effect of method was followed up with pairwise t -tests, using the 3C model as the reference group. The Holm adjustment was performed to correct for multiple comparisons. See footnote on Table 1 for abbreviations. For female athletes, the Pearson's correlations between the reference 3C model and alternate methods ranged from 0.

The current study had two primary aims: A to determine the most accurate skinfold prediction equations for young male and female athletes using a three-compartment model of body composition assessment; and B to examine the utility of alternative modes of body composition assessment compared to criterion measures.
This is the first study to examine the validity of skinfold prediction equations in young male and female athletes. The main findings indicate multiple discrepancies in FFM estimates for female and male athletes when compared to the 3C model.
In females, The Evans 3 and 7-site, Forsyth, and Jackson and Pollock 3-site SKF prediction equations performed best, while the Evans 3-site equation appeared to perform best when determining FFM in male athletes.
Additionally, the field 3C model can provide a suitable alternative measure of FFM for both male and female athletes when laboratory-grade criterion measures are not available. In females, the SKF prediction equations of Devrim-Lanpir 26 , Durnin and Womersley 38 , Jackson and Pollock 7-site 33 , Katch 35 , Loftin 42 , Lohman 16 , 36 , Slaughter 43 , and Thorland 16 , 37 differed from the 3C model Figure 1.
In the context of wrestling and MWW determination, this suggests the estimates of FFM and subsequently MWW are likely to fall within the limits of each weight class division often in 5.
However, this could impact wrestlers who are on the threshold of a certain MWW and weight class. There was evidence of proportional bias for the skinfold equations of Durnin and Womersley 38 , Evans 3-site and 7-site equations 1 , Jackson and Pollock 3-site and 7-site 32 , 33 , Katch 35 , Loftin 42 , Lohman 16 , 36 , Slaughter 43 , and Thorland 16 , 37 Figure 3.
Collectively, these findings indicate the Evans 7-site equation appears to perform best among SKF prediction equations for female athletes when determining FFM.
This could potentially allow a female wrestler to compete in a lower weight class than what would be allowed if FFM was assessed more accurately. Among the remaining body composition assessment modalities, no differences were observed between 3C Field, ADP [both Siri 44 and Brozek 45 equations], nor the UWW Brozek and Siri equations compared to the criterion 3C model when determining FFM for females.
The 3C Field resulted in a mean difference SEE of 0. However, there was proportional bias for the 3C Field, indicating that the model tended to overestimate FFM in those with low FFM levels but underestimate FFM in those with higher FFM. However, it should also be noted that the performance of the Field 3C model is dependent upon the field methods used to estimate D b and TBW, so alternate versions of this model may produce dissimilar results.
The 3C Field, UWW [both Siri 44 and Brozek 45 equations], ADP [both Siri 44 and Brozek 45 equations] all demonstrated equivalence with the reference 3C model.
However, there was also proportional bias for the F2FBIA Tanita , and BIS, which again indicates a tendency to overestimate measures of FFM in those with higher FFM. In male athletes, the FFM values derived from the SKF equations of Devrim-Lanpir 26 and Jackson and Pollock both 3-site and 7-site equations 32 differed from the 3C model Figure 4 while proportional bias was present for the Devrim-Lanpir 26 , Durnin and Womersley 38 , Evans 3-site and 7-site 1 , Forsyth 34 , Jackson and Pollock 3-site and 7-site 32 , 33 , Katch 35 , Lohman 16 , 36 , and Thorland equations 16 , 37 Figure 6.
The current MWW certification process for high school boys wrestling in Wisconsin utilizes the Lohman equation, which comparatively, resulted in a mean difference SEE of 0. The Field 3C model resulted in a mean difference SEE of 1.
However, proportional bias was present for the 3C Field, with a tendency to overestimate FFM in those with lower FFM but underestimate FFM in those with higher FFM.
Proportional bias was present for the F2FBIA Tanita indicating greater underestimation of FFM values in those with higher FFM. FFM was underestimated for most males by Tanita and became more pronounced as FFM increased as indicated by the negative slope of the Bland—Altman line Figure 6.
Previous research in college-age men 25 reported discrepancies in MWW values with SEEs of 3. Clark et al. However, the authors 58 reported large individual differences and systematic bias across the range of MWW values.
Additionally, the BIA was able to predict MWW within 3. Others reported no differences in MWW from UWW The UWW and SKF exhibited the highest degree of precision lowest SEE with SEE values of 1.
In most high school settings, SKF is likely the modality of choice because of its low cost and ease of use. Conversely, Clark et al. In high school wrestlers, the Lohman SKF equation was found to be a valid measure of FFM with a SEE of 2.
Furthermore, impedance devices may have limitations with athletic populations, as previous research has indicated that generalized impedance-based equations underestimate body fluids in athletes, potentially influencing measures of FFM.
Future investigations in a large, mixed-sex group could provide new equations SKF and impedance for estimating FFM in youth athletes. Results from the current study indicate the Evans 7-site and 3-site SKF equations performed best for female and male athletes, respectively. The current MWW certification process for girls' high school wrestling in Wisconsin does not appear to utilize the best SKF prediction equation available for this population.
This could permit a female wrestler to compete in a lower weight class than what would be allowed if FFM was assessed more accurately. For male wrestlers in Wisconsin, the Lohman equation is currently used, which provided an adequate estimate of FFM yet was not the best performing SKF prediction equation.
The field 3C model can provide a suitable alternative measure of FFM for both male and female athletes when laboratory-grade criterion measures are not available. The datasets associated with the current manuscript are not readily available as additional analysis is pending.
