: Skinfold measurement for coaches| Measurement Toolkit - Simple measures - skinfolds | Sport performance is highly dependant on health, skill related components of fitness, technique in sport specific skills and body composition. This is because our body composition can contribute to elements including strength power, speed and agility. There are a variety of techniques to assess body composition and the right method depends on various factors including accuracy, reliability, expense, portability, invasiveness and technical expertise. Coast Sport, the leading providers of a multidisciplinary allied health practice, a leading provider of world class integrated healthcare services and sports performance uses Subcutaneous Skinfold Thickness Skinfolds and Dual Energy X-Ray Absorptiometry DEXA to assist athletes and the general population meet their goals and potential. These two methods will be discussed in more detail below. Skinfolds are the routine monitoring of body fat and distribution among athletes across state academies and institutes of sport in Australia. They are taken at various anatomically identified sites on the body at seven sites triceps, subscapular, biceps, supraspinale, abdominal, front thigh and medial calf which are chosen to account for individual variation in body fat distribution. This is referred to as the skinfold sum and there are set ranges ideal for different sports and player positions that ideally enhance playing capabilities. These measurements are usually in conjunction with body mass and waist circumference to provide an insight into body fat and muscle mass. It is best to have skinfold measurements taken by the same trained practitioner throughout a season or training period to provide greater accuracy. Most sports dietitians will have specialised training in anthropometry ISAK qualification and can also guide dietary changes to alter your body composition to help maximise your performance without negative side effects. Skinfold measurements can be used by athletes and coaches to assess the effectiveness of training and guide targeted personalised training or nutrition programs. DEXA is the gold standard in measuring body composition as it enables to see a breakdown of everything that contributes to your overall weight and make appropriate adjustments to better health outcomes and performance. 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.

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. A vertical fold taken at the widest point of the calf at the medial inner aspect of the calf. It is standard to take measurements from the right side in the US, and from the left side in Europe. When selecting the side it is important to be consistent. The site to be measured is marked once identified. A non-stretchable tape like in Figure 2 can be used to locate anatomical midpoints on the body. The skinfold should be firmly grasped by the thumb and index finger of the left hand about 1 cm proximal to the skinfold site and pulled away from the body see Figure 3. The caliper is in the right hand perpendicular to the axis of the skinfold and with dial facing up. The caliper tip should be 1 cm distal from the fingers holding the skinfold. The dial is read approx. Measurement is recorded to the nearest 0. Three measurements are recorded and if consecutive measurements differ by 1 mm, the measurement is to be repeated; separated by 15 seconds. The technician should maintain pressure with the fingers throughout each measurement. Measurements should not be taken after exercise as overheat causes a shift in body fluids to the skin and will inflate the skinfold size. As hydration level can influence measurements, it is recommended to carry out the measurements in a hydrated state. Figure 4 An example of a calibration block. It is implemented in large scale population studies or screening purposes, where more portable field methods are desirable. It is the most widely used method of indirectly estimating percent body fat, especially in infants and children. Several equations are available.

Skinfold thickness-for-age indices 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. Strengths and limitations. An overview of skinfold thickness methods is outlined in Table 5. The majority of national reference data available are for skinfolds at the triceps and subscapular locations. The triceps skinfold varies considerably by sex and can reflect changes in the underlying triceps muscle rather than an actual change in body fatness. Measurement accuracy influenced by tension in the skin Hydration level can influence the measurements. Dehydration reduces the skinfold size. Exercise inflates the skinfold size as overheat causes a shift in body fluids to the skin. Oedema and dermatitis increase the skinfold size.

Skinfold measurement for coaches -
Examples include the Holtain see Figure 1 , Lange and Harpenden calipers see instrument library for more details. The Lange and Harpenden calipers have been used in developing prediction equations and reference values Lee [ 20 ]. The Lange is most popular in the US, and the Harpenden and Holtain in Europe.
Figure 1 Example of skinfold caliper typically used in children and infants. 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.
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 subscapular and triceps skinfolds are the most commonly used. Figure 2 Anatomical sites for skinfold thickness measurement taken at the left side.
Source: MRC Epidemiology Unit. The following are the nine anatomical sites as illustrated in Figure 2 that are most commonly used in the assessment of skinfold thickness:. Figure 3 Quadriceps skinfold thickness in an infant to the left and triceps skinfold thickness in an adult to the right.
An example of a calibration block with known thicknesses Figure 4 is used to calibrate skinfold calipers. Typically, calibrations are carried out on a monthly basis. Skinfold thickness are typically recorded in mm.
Some calipers record in both mm and cm. The skinfold thickness values should be quality checked during data processing in the same manner as other health related variables, for example by checking for outliers and data entry errors.
Raw skinfold thickness values are often used and they act as reliable indicators of regional fatness. In a similar way to body mass index BMI , they can be converted into standard deviation scores SDS for longitudinal evaluations. The triceps site is the most commonly used single-site skinfold measurement as it is easy to measure and reference data e.
WHO triceps skinfold thickness for age are available for comparison. However, no equations are available for estimating body fat from a single-site skinfold measurement.
Triceps measurement is also used to derive indices of body composition using arm anthropometry. To convert raw skinfold thickness values into a percent of body fat, population-specific or generalised equations are used.
These equations are derived from empirical relationships between skinfold thickness and body density. Many equations firstly calculate body density and require an additional calculation to estimate percent body fat. 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.

The dial is read approx. Measurement is recorded to the nearest 0. Other studies, for example on obese children, have found good agreeance between skinfolds and percent fat measured by DEXA 22 , however, considerations based on the population being measured must be addressed by each case separately.
In anthropometry, technical error of measure TEM is what we refer to the error that occurs when a measurement is taken on the same object more than once, and the values are not the same.
This error is inherent especially when humans are involved in the measurements, due to:. 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.

Although there are numerous ways to measure body composition, the method of skinfold calipers for estimating body composition is often disregarded as a good choice. Many things can affect the accuracy of the measurement of body composition using calipers, including the equipment, the level of expertise of the tester, and which equation is used for prediction, however, skinfold calipers can still offer a relatively accurate and quick, affordable way to measure body composition changes over time.
