3d body scanners use infrared sensors to get a. When operating the light wand sends a nearinfrared light beam into the biceps of the dominant arm at specific wavelengths.

Near infrared body fat measurement. Fitness testing tests anthropometry body composition near infrared interactance. More specifically it is based on the ability of fat tissues to absorb more infrared light than lean tissue which can then be measured as a change in the infrared level. Portable analyzers using nearinfrared interactance nir principle have been proposed for the direct measurement of percent body fat. The percentage of essential body fat for women is greater than that for men due to the demands of childbearing and other. Body fat measurements can now be done much easier faster but with the same precision by using the futrex body fat analyzer. Measuring body fat with nir near infrared interactance.
The near infrared interactance nir method of assessing body composition is based on the principles of light absorption reflectance and near infrared spectroscopy. The futrex control software included in the delivery has some more advantages to offer. The aims of this study were to model the effect of varying volume fractions of melanin and water in skin over nir spectra and to define sensitivity of nir reflection on changes of thickness of subcutaneous fat. This method uses the principles of light absorption and reflection more specifically transflectance and interactance to analyze body fat. One potential low cost approach for obtaining direct measurements of body fat is near infrared nir interactance. For a 7 site measurement in women the chest area near the armpit and area.
Nir a fiber optic probe is connected to a digital analyzer that indirectly measures the tissue composition fat and water at various sites on the body. Futrex works with innovative near infrared measurement technology. Near infrared interactance is one of many measures of body composition which uses a computerized spectrophotometer which has a single rapid scanning monochromator and fiber optic probethis method uses the principles of light absorption and reflection to measure body fat. The body fat percentage bfp of a human or other living being is the total mass of fat divided by total body mass multiplied by 100. Here are the 10 best ways to measure your body fat percentage. Body fat includes essential body fat and storage body fatessential body fat is necessary to maintain life and reproductive functions.
This measurement is based upon light in the near infrared spectrum at a wavelength slightly longer than the eye can see. Near infrared interactance uses a computerized spectrophotometer via solid state optics.
