Body measurements Info

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. Skinfold testing also known as calliper testing is a commonly used method to determine a clients body fat percentage. Using the jackson and pollock equation outlined above she calculates that her body density is 10429 and her percentage body fat is 2464. Sarah is a 45 year old female. A skinfold caliper is used to assess the skinfold thickness so that a prediction of the total amount of body fat can be made. Skinfold measurement skinfolds provide an estimate of body fat and some skinfold ratios have been proposed for use in evaluating fat distribution.

The skinfold caliper is a device which measures the thickness of a fold of your skin with its underlying layer of fat. A skin fold test is a method of estimating body fat percentage by taking skin fold caliper measurements in 3 9 different locations on the body see glossary for pictures and then applying the results into one of the various formulas available. Place the body fat calipers less than 12 inch from your pinch midway between the crest and the base. Once you have determined your body density you can calculate your percent body fat as follows. Measurements are taken at either 3 or 7 different sites on the body. 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.

But dont take the three measurements consecutively instead run through all the sites three times. The body fat caliper calculator helps do all the computations for you regardless of the method you want to use. By doing this at the key locations can be a quite accurate representative of the total amount of fat that is on your body it is also possible to estimate the total percent of bodyfat on your body. Skinfold calipers measure the thickness of your subcutaneous fat the fat underneath the skin at certain body locations. As such a 45 and s 120. This technique of measurement is based on the densitometry technique underwater weighing and the prediction equations are population specific.

The sum of her seven skinfold measurements is 120 mm. 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. For each of the skinfold sites take three measurements and use the average of those three. Some skinfolds subscapular and tricipital have been described as markers of the central distribution of fat mass and others have been correlated with subcutaneous abdominal fat. 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.
