In Interpretaion effort to standardize measurements, guidelines for the anatomical location of skinfold sites and measurement technique have been published [4, 5], most recently by the International Society of Kinanthropometry ISAK[6].

Interpretation of skinfold measurements -

Both circumference and electrical impedance have a larger percentage of error, so the blog will compare the accuracies of the Durnin-Womersley four-site skinfold and the Jackson-Pollock seven-site skinfold.

While other methods for skinfold measurement exist, these are the two most commonly used. For our research, we will use six individuals of varying gender, body size, age, and shape to compare the different methods.

According to our anthropometric findings, the variation between the four and seven-site, is greatest in females and the largest differential occurs with age. The four-site has a larger fluctuation with older females and this is supposed to account for lower body density resulting in more visceral fat accumulation.

Fifty to Seventy five percent of fat is subcutaneous, thus the difference in estimate between methods can only be proportional to the remaining body weight.

According to the American Journal of Clinical Nutrition, select skinfold equations can have a marked overestimation of body fatness. The Jackson-Pollock seven-site skinfold test is known to be more accurate because of the formulation, variation, and quantity of sites being used having a relatively low margin of error in comparison to hydrostatic weight of only 3.

A lot of individuals have differing shapes in the lower body region, and none are included in the Durnin-Womersley skinfold test, making it more reliant on estimation. Regardless, periodic skinfold measurements will give a reflection of change despite the estimate of body fat percent.

Trying to gain muscle mass or reduce your fat mass? There are a variety of measurements that tell you a lot more information about your body than simple weight measurement does, for example DXA scans, Bod Pods, BIA and surface anthropometry skinfolds.

These types of measurements all come with their own unique set of errors and benefits with their estimation of physique. See the table below for a summary of the accuracy and reliability of different body composition assessments that can be undertaken:.

At Precision Athletica, we primarily assess skinfold measurements. Skinfolds are a robust technique that is relatively cheap, convenient and efficient, and does not require any fasting beforehand, compared to other methods which are more expensive and can give variable results based on the time of day, meals eaten and hydration status.

In a skinfolds assessment, 8 anatomically defined sites on the body triceps, subscapular, biceps, iliac crest, supraspinale, abdominal, front thigh and medial calf are marked to then assess subcutaneous fat fat below the surface of the skin using skinfold callipers.

The sites are chosen to account for individual variations in body fat distribution and the results are given as a sum of the 8 sites some sports will only measure 7 sites, leaving out the iliac crest measurement. Skinfolds only measure subcutaneous fat, not visceral fat, which is the internal fat surrounding organs, however this is not usually an issue for athletes.

In general, an increase in skinfolds is associated with an increase in body fat, while decreased skinfolds is associated with a reduction in body fat stores. Skinfolds are typically assessed in conjunction with your body mass, to offer an insight into changes in both fat and muscle mass i.

increased weight with reduced skinfolds could reflect increased muscle mass. See the table below for an example of how your skinfolds can be interpreted to assess changes in body composition:.

As with many types of measurements, there is a margin of error associated with skinfold assessments. You will be given a sum of your 8 or 7 skinfold sites, but this should also be presented as a range to allow for measurement error.

When you have a subsequent skinfold measurement, if your skinfolds sum is not in the range of the previous measurement, then you know there has been a true change in fat mass, however if it falls within that range then it can be viewed that skinfolds have remained stable.

Frequent ongoing measurement of your skinfolds will be a valuable tool in helping you monitor body composition over time. We recommend every weeks depending on the athlete and sport.

The Online game resource recharge method, the measurement of subcutaneous fat Measuements, is the most fo adopted field method for the assessment Interpretwtion body fat, especially Plant-based fats children.

PEA PODcan only measure infants up to 10kg. The skinfold method involves measuring the skinfold subcutaneous fat thickness at specific sites of the body using a skinfold caliper and a non-stretchable measuring tape to correctly locate the measurement area. The cost of calipers ranges from £9 to approximately £ For research purposes, calipers with a more refined scale e. Examples include the Holtain see Figure 1Lange and Harpenden calipers see instrument library for more details.
