What is skinfold caliper?
A skinfold caliper is used to assess the skinfold thickness, so that a prediction of the total amount of body fat can be made . This method is based on the hypothesis that the body fat is equally distributed over the body and that the thickness of the skinfold is a measure for subcutaneous fat.
How many skinfolds are there in the body?
The sum of four skinfolds. To estimate the total amount of body fat, four skinfolds are measured: Biceps skinfold (front side middle upperarm) Triceps skinfold (back side middle upperarm) Subscapular skinfold (under the lowest point of the shoulder blade) Suprailiac skinfold (above the upper bone of the hip) For this measurement the patient must be ...
Why is the triceps skinfold the most reliable?
Of all skinfold measurements, the triceps skinfold is the most reliable one to assess, because oedema is not often seen in the upper arm. The measurements are less reliable in elderly people, due to their weak skin and muscles. As a result, their muscles are often taken in the skinfold. Also in patients with chronic muscle diseases, dehydration and oedema, skinfold measurements can give unreliable values. Lastly, the measurements should be performed by a trained person; the accuracy of the measurements largely depend on the way they are done.
What is the tricep skinfold?
The triceps skinfold. The triceps skinfold is necessary for calculating the upper arm muscle circumference. Its thickness gives information about the fat reserves of the body, whereas the calculated muscle mass gives information about the protein reserves.
Where is the suprailiac skinfold?
Suprailiac skinfold (above the upper bone of the hip) For this measurement the patient must be able to sit or stand in an upright position. Skinfold measurements are cheap, not very painful and easy to perform, although practice is required.

It's better to repeat the measurements for a good indication of changes in nutritional status and body fat mass. For information about calculating the upper arm area, upper arm circumference, upper arm fat area, upper arm muscle area, go to the page on ' Anthropometry '.
Is skinfold measurement reliable?
Also in patients with chronic muscle diseases, dehydration and oedema, skinfold measurements can give unreliable values. Lastly, the measurements should be performed by a trained person; the accuracy of the measurements largely depend on the way they are done.
Who developed the equation for body fat percentage?
With this information, scientists have developed equations that help us estimate the total body fat percentage. Matiegka was the first to develop equations for predicting body fat percentage from skinfold thickness (Stewart, Marfell-Jones, Olds, de Ridder, 2011).
Does skinfolds underpredict body fat?
Furthermore, skinfolds tended to underpredict body fat percentage as compared to DEXA, revealing that DEXA and skinfold could not be used interchangeably. According to this study, and others (Duz et al., 2009; Lean, M., Han, S, Deurenberg, 1996), skinfolds may have a significant bias at extremes of body fat and age.
Is DEXA more accurate than skinfold?
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 (Donini et al ., 2013).
Is skinfold caliper accurate?
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, ...

What is the purpose of a caliper for skinfold?
It’s important not to pinch too hard as this could disrupt the accuracy of the test. The caliper is used to determine the skinfold in millimeters. The thickness of the skinfold represents the amount of fat (in millimeters) at that particular location on your body.
How to measure chest size?
To measure the chest, diagonally pinch a fold that is halfway between the armpit and the nipple. For women, you’ll want to pinch 1/3rd of the way between the armpit and nipple. This will allow you to pinch far enough away from the breast tissue to get an accurate reading.
How to calculate body fat percentage?
Firstly subtract your present % body fat from 100 and divide this by 100 minus the desired % body fat. Multiply this by the present weight and this will give you the weight for the desired % body fat. For example, a female 145 lb. who is now 32% body fat.

How to find the lean mass?
It is very easy to determine and simply involves finding the weight of the "lean mass" by measuring % body fat and weight. Since muscle tissue is the component of the lean mass that can change the most, changes in the lean body weight are going to be caused mostly by changes in the weight of the muscles.
