If there is any reason to believe that the scales are not accurate do a complete recalibration. The technician assigned to the body measurement station should apply a random set of the standard weights daily to roughly check the accuracy of the weight scales.
Pdf Techniques Used In The Measurement Of Body Composition
Body measurement techniques. The percentage of body fat can be calculated from overall body density. Bioelectrical impedance analysis bia. Volume is measured by the bod pod. Prior to taking the body measurements it is advisable to understand the customers requirements concerning the shape fit and style of the garment. A technician uses the device by pinching a layer of skin to get any underlying fat. We know the density of fat muscle and bone and water.
Bioelectrical impedance analysis technique is used to predict body composition based on the electrical conductive properties of the body29and involves measuring the impedance z to the flow of a low electrical current 800 μa at a fixed frequency 50 khz. Measure the circumference of your waist. Skin calipers are the most accessible method in determining body fat percentage. This check is noted in the equipment calibration log. Place one end of the tape measure at the fullest part of your bust wrap. The following points have to be taken into account while taking body measurements.
For example the us army uses a body fat calculation that simply requires an individuals age height. Triceps pectoral abdominal supriliac and thigh. Measure the circumference of your chest. The bod pod taps into adp technology air displacement plethysmography if you want to get fancy which uses air displacement to measure body volume and calculates lean and fat mass. Measuring the circumference of certain body parts is a simple method of body fat estimation. Available techniques allow for the measurement of fat fat free mass bone mineral content total body water extracellular water total adipose tissue and its subdepots visceral subcutaneous and intermuscular skeletal muscle select organs and ectopic fat depots.
Underwater weighing technique underwater weighing which is one of the oldest body measurement techniques is used to calculate the body fat percentage. Check out the easy to follow instructions for getting accurate measurements for each body part below. In this technique determined based on the archimedes laws the person to be measured is weighed in a water tank on a swing like chair. Use the tape to circle. Ongoing efforts involve multisegmental and multifrequency bioelectrical impedance analysis quantitative magnetic resonance for total body water fat and lean tissue measurements imaging to further define ectopic fat depots. Sites that are measured are.
Since the density of an object in this case your body equals mass divided by volume we know mass equals your body weight.
