What are Body Measurement Techniques?
It is necessary to perform height and weight analysis and obtain the ideal weight according to these results to consider the body healthy. Today, body measurement techniques used to obtain this data involves various methods. These techniques measure the body fat, muscle, and water percentages in in detail.
Underwater Weighing Technique
Underwater weighing, which is one of the oldest body measurement techniques, is used to calculate the body fat percentage. 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. In the meantime, the person is asked to exhale and discharge the air in his/her lungs. Thus, a much more accurate measurement will be ensured. The logic of this technique is that the body fats are heavier than water. In an underwater measurement, the person weighs less than he/she weighs outside. These values are compared with the weight measurements performed outside, and the fat percentage is determined by subtracting the first value from the latter. Underwater weighing is carried out only in large laboratories, by professional people, as it requires special devices.
Dexa technique is also among the body measurement techniques applied today. Besides calculating the body fats, this method also determines which parts of the body these fats are collected the most. An x-ray device is used for Dexa measurement. This device turns around the body, and it measures the amount of fat, muscle, and bone in the body. This process, which is completed in approximately 15-20 minutes, is quite widely used today. Dexa measurement devices are available in full-fledged hospitals.
Skinfold Calipers and Bioelectrical Measurement Techniques
As one of the body measurement techniques, the Skinfold Calipers method is usually known for its application to athletes. Accordingly, the amount of fat in different parts of the body is calculated in millimeters. These measurements are taken from at least three parts of the body.
The method called as Bioelectrical Analysis is one of the most effective body measurement techniques. In this method, while the electrical conductivity of the lean tissues are higher, adipose tissues do not have this conductivity. The electrodes connected to the person can make this measurement.
