Accurate measurement technique is important. Take all measurements on the right side of your body.

What are normal skinfold measurements. Variations of this measurement site has the measurement taken 1 cm 2 cm and 1 inch to the right side of the umbilicus. Another is 3 cm lateral to the midpoint of the umbilicus and 1 cm inferior to it. Take a minimum of two measurements at each site. Perpendicular to the skin fold. Two equations are required for this process one to estimate body density and one to estimate percent body fat from the body density. The tricep skin fold measurement and mid arm circumference are used to calculate the mid arm muscle circumference and all three are compared with age and gender specific normal values to evaluate fat and muscle stores in children older than 1 year.
Also note that the skinfold is sometimes taken with a horizontal fold. One third of the distance between the anterior axillary line tricep. This site is also occasionally known as the paraumbilical skinfold site. Skinfold measurement taking skinfold measurements is a common method for determining body fat composition. The acceptable range between repeated measures is 1mm. If the values vary by more than 1mm take an additional measurement and use the average of the three measurements.
Professionals use a variety of different equations depending on how many skinfold sites are taken and the gender age and ethnicity of the person being measured. 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. To estimate the total amount of body fat four skinfolds are measured. Skinfold measurements should not be taken when the skin is wet or after exercise. And the nipple chest. 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.
Vertical fold posterior midline of the upper arm halfway between the acromion. Release the caliper lever so its spring tension is exerted on the skinfold. Do not take measurements after physical activities or when you are overheated. Skinfold measurement equations can help produce a relatively accurate estimate of body fat as long as the measurements are taken correctly. Measurements should be made on the right side of the body. Calipers are used to measure the thickness of the skin at a range of sites around the body.
Halfway between the crest and the base of the fold. Caliper should be placed 1 2 cm away from the thumb and finger. Maintained pinch while reading caliper. To grab the skinfold easily and correctly make sure your skin is dry and lotion free. 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. One half the distance between the anterior axillary line crease of the underarm and the nipple women.
The added fluid under the skin may increase skinfold thickness. 1 standard deviation scores are used to interpret data in terms of the number of standard deviations above positive value or below negative value the median 50th percentile value for normal controls of the same age and gender.
