  1. Common Skinfold Locations Subscapula Taken 2cm along the natural cleavage line, from the undermost tip of the inferior angle of the scapula. ( A I S ) Iliac-crest Taken on a slight diagonal, this fold is immediately. superior to the iliac crest. Calf Taken vertically at the most medial aspect of the calf; also at it's maximum circumference. ( A I S ) Mid-axilla Vertical fold taken at the height of the xyphoid Process most inferior aspect, along the ilio-axilla line. Tricep A vertical fold taken at the most posterior surface of the triceps brachii when viewed from the side. ( A I S ) Abdominal Taken vertically with a broad grip, 5cm lateral to the omphalion (centre of the umbilicus). ( A I S )

  2. Bicep Taken vertically at the midpoint, and most anterior aspect of, the bicep brachii muscle. ( A I S ) Thigh Vertical fold midway between the inguinal crease and proximal border of the patella. ( A I S ) ( A I S ) - signify the 7 sites most commonly used by the Australian Institute of Sport & many other nations after the 1996 Atlanta Games. t e c h n i q u e 1) All measurements are taken on the right side of the body.2) Locate site (mark with texta for beginners) & ensure that this is where the fingers pinch the skin.3) Pinch skin between thumb and index finger so that a fold of skin creates an elevated line in the desired direction. 4) Clamp the calipers perpendicular to the fold & 1cm lateral or inferior to the thumb & the index finger,5) Maintain pressure with fingers and calipers reading measurement after 2 seconds.6) Unclamp calipers from skin; release tension slowly so as not to damage them, then relax thumb and index finger.7) Take each measurement in sequence and then repeat. Measure a third time if there is more than a 10% discrepancy.8) Practice makes perfect (SKF) measurements can use the thickness of subcutaneous adipose tissue, to estimate body density; once this is known for an individual, % body fat can be estimated using normative data for their age, gender, race and fitness level.  a s s u m p t i o n s 1) SKF is an accurate measure of subcutaneous fat.2) A direct relationship b/n % BF found adipose tissue & Total BF exists.3) Fat distribution is similar for all individuals of the same gender within a sample population.4) There is a relationship between the sum of skinfolds and body density.5) Age is an independent predictor of density for males & females.6) The compartment model for FM & FFM used in equation is valid for the subject. 7) Calipers are calibrated and are of a high quality. 8) Skin and subcutaneous fat has constant compressibility. 9) Constant skin thickness at each individual site. c o n s i d e r a t i o n s * Skin should be dry, no lotions or sweat. * Don't measure directly after exercise, or excessive hydration to avoid elevated or lowered body fluids. * Use the same high quality calipers (Harpenden or Lange) & same tester in all tests. * All measurements should be in mm. * (SKF) is not valid for obese individuals.
