Jackson and Pollock have devised other formulas for 3, 4 and 7 skinfold sites. For example, the Durnin and Womersley 4 site method uses the biceps, triceps, subscapular and suprailiac sites. One of the most accurate methods of estimating the amount of fat is through measuring skinfolds through the caliper test which is applied in certain anatomic places. There are several means of estimating body fat percentage and most of them account for the gender of the subject because females tend to have higher levels of fat due to hormonal regulation and preparation for bearing children.īody fat is separated into two components, essential fat (which supports basic processes) and reserve or storage fat (the variable amount from the adipose tissue). This is an indicator of the general fitness level of the body and reflects the amount of fat mass to the total body mass. The BMI formula is weight divided by squared height.įor women: BMR = 655 + (9.6 x Weight) + (1.8 x Height) - (4.7 x Age)įor men: BMR = 66 + (13.7 x Weight) + (5 x Height) - (6.8 x Age) Body fat percentage The lean body weight is computed as the difference between body weight and fat mass. The body fat percentage is then transformed according to the subject weight in body fat mass based on the following: This is used to determine the minimum calorie requirement. ■ Activity level – ranging from sedentary to extra active, with explanations for each level. ■ Hip measurement – in case the gender selected is female, this extra field is required, in inches or centimeters ■ Waist measurement – in either inches or centimeters, the tape follows the waist line and the most accurate reading is input ■ Neck measurement – in either inches or centimeters, by measuring the neck circumference in the middle ■ Height – can be expressed in inches or centimeters, this is used to determine BMI and BMR ■ Weight – can be expressed in pounds or kilograms The navy method body fat measurement calculator requires the following input: The last item in the result comprises of the minimum calorie requirement, that can be used as a starting point for those who want to consume the adequate amount of calories to maintain their weight. Alongside, the BMI and BMR values are calculated and a fitness level is declared. This health tool can be used to determine the body fat in percentage and mass and the lean body weight. How does the navy method body fat measurement calculator work?
