Triceps= 21 Thigh = 16 Suprailiac = 11 Abdomen = 26 įat percentages can offer information on the fitness levels of the body: Fat levelġ) Jackson AS, Pollock ML, Ward A. Taking the case of a male aged 27, weighing 178 lbs and having the following skinfold measurements: Lean body mass is calculated as the difference between weight and body fat mass because it represents the portion of weight that is lean (not made of fat). The body fat percentage uses the sum of the skinfolds in two different formulas, adapted for gender:īF% Females = (Triceps + Thigh + Suprailiac + Abdomen) x 0.29669 - (Triceps + Thigh + Suprailiac + Abdomen) 2 x 0.00043 + Age x 0.02963 + 1.4072īF% Males = (Triceps + Thigh + Suprailiac + Abdomen) x 0.29228 - (Triceps + Thigh + Suprailiac + Abdomen) 2 x 0.0005 + Age x 0.15845 – 5.76377īody fat mass is extracted from the above percentage with the use of weight: Other advice in regard to testing focuses on taking the measurements as accurately as possible, at the same time of the day and never after exercise. Some sources argue that skinfold measurements should be used just to monitor progress and are not very reliable when it comes to comparing with fat percentages from tables. In some cases, it is normal that measurements are repeated. In order to ensure consistency, it is recommended that the measurements are all taken on the same side of the subject. The most accurate but also complex method of assessing body fat is that of ultrasound testing. The Durnin and Womersley is another 4 skinfold method while Jackson and Pollock have devised another two formulas, one for 3 site testing and another for 7 skinfolds.īody fat percentages can be extracted from body circumferences, such as those from the US Navy tape measure method (neck, waist, hip). It can be performed at home and upon the purchase of skinfold calipers (most are designed to be used by a second person, very few are for self-use), less costly than periodically having the measurement taken by a specialist. ![]() ![]() Skinfold testing provides a simple way to monitor changes in body composition that may occur in time. ■ Abdomen – Vertical fold, 2 cm to the right side of umbilicus. ■ Suprailiac – Diagonal fold, immediately superior and in line with the angle of the iliac crest, on the anterior axillary line. ■ Thigh – Vertical fold on the anterior midline of the thigh, half way between the proximal border of the patella and the hip. The arm should be held freely to the side of the body. ■ Triceps – Vertical fold on the posterior midline of the upper arm, halfway between the bony processes (shoulder and elbow). ■ Weight – subject weight can be input in pounds or kilograms and is used to determine body fat and lean masses. ■ Age – the formulas also account for the age of the subject. ■ Gender – is needed because there are different formulas for males and females. There are several fields to input in the body fat 4 site skinfold measurement calculator, each contributing to a particular area of the result: ![]() Beside this, it offers information on the body’s fat and lean masses. This health tool can help you determine the body fat percentage based on 4 skinfold measurements taken with calipers. How does this body fat 4 site skinfold measurement calculator work?
