There is in depth information below the form on the formulas used and on how to measure skinfolds with calipers. This is halfway between the 28 and 30 on the chart. Skinfold measurement equations can help produce a relatively accurate estimate of body fat as long as the measurements are taken correctly. This technique of measurement is based on the densitometry technique underwater weighing and the prediction equations are population specific. How does this body fat percentage 3 site skinfold test work. The body fat caliper calculator is based on the skinfold method of determining body fat percentage.

These are all extracted from three measurements of skinfolds performed with an instrument called caliper. Body fat percentage formula for men seven skinfold sites all 7 sites from above sum7 is the sum of all the measurements in mm. Skinfold testing also known as calliper testing is a commonly used method to determine a clients body fat percentage. This health tool estimates the amount of fat present in the body in percentage and as fat mass the lean body mass and body density. How do i take body fat caliper measurements. The skinfold method measures skinfold thickness at 3 to 9 different locations on the body depending on the method used then computes body density and with it the total body fat percentage.

Here is an example of a 7 site skinfold assessment. For results to be valid and reliable the skinfold measurements must be taken properly and they should be taken by the same technician from one measurement to the next. Two equations are required for this process one to estimate body density and one to estimate percent body fat from the body density. To get accurate figures it is necessary to interpolate. For example a female in the 16 29 age groups could have a sum of 29mm for the four measurements. This body fat 4 site skinfold measurement calculator determines the body fat percentage based on the triceps thigh suprailiac and abdomen skinfolds.

Measurement errors can range from 355 body fat 3. The most commonly used equations for body fat calculations based on skinfold measurements are based on jackson pollocks equation for bone density and siris formula to get body fat percentage from that. Caliper procedures all calculator measurements should be made on the right side of the body caliper should be placed 1 cm away from thumb and finger perpendicular to skinfold and halfway between crest and base of fold pinch should be maintained while reading the caliper. The bodyfat for 28mm is 186 and that for 30 is 195. Skinfold measurement is based on the belief that approximately 50 of total body fat lies under the skin and involves measuring the thickness of the skinfolds at standardized sites. Summary estimating body fat percentage with skinfold calipers is.
