How to measure a skinfold:
1 – Identify the anatomical references that will help locate the skinfold (DC)
2 – Locate the points to be measured and mark them with a dermographic pencil or a ballpoint pen. Only after locating these should measurement start. At this point, the caliper will take the measurement.
3 – The measurer should use the fingers to pinch the fold at a distance of 1.5 to 2 cm from the application point of the caliper.
4 – Each skinfold has a specific direction (longitudinal, transversal or oblique) that should be observed. For example: The skinfold of the abdomen can be measured either on the right or on the left side of the navel, as well as measured longitudinally or transversally. This will be defined by the protocol that is being used, but once the position is defined it cannot be changed.
5 – The pressure of the fingers when pinching and holding the skinfold should not cause discomfort during measurement.
6 – Hold the caliper with the right hand and pull out the skinfold with the left hand. The palm of this hand should be facing the measurer.
7 – The muscle of the assessed region should remain relaxed.
8 – The measurement should be repeated 2 or 3 times as instructed below, and it must not have a variation higher than established.
