Portable analyzers using nearinfrared interactance nir principle have been proposed for the direct measurement of percent body fat 21. 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.
Buy The Validity And Reliability Of Near Infrared
Near infrared body fat measurement. In near infrared interactance nir a specialized probe is placed against an area of the body emitting infrared light that passes through muscle and fat. One potential low cost approach for obtaining direct measurements of body fat is near infrared nir interactance. Near infrared technology behind bello measures lipid water oxygenated and deoxygenated hemoglobin. Redirected from near infrared interactance 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. Bello is the first and only portable device that can directly quantify lipid underneath the skin and provide the most accurate measurement of belly fat anytime anywhere. The near infrared interactance nir method of assessing body composition is based on the principles of light absorption reflectance and near infrared spectroscopy.
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. 3d body scanners use infrared sensors to get a detailed look at the shape of your body the sensors generate a 3 d model of your body. Measuring body fat with nir near infrared interactance. Essential body fat is necessary to maintain life and reproductive functions. Body fat includes essential body fat and storage body fat. 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.
When operating the light wand sends a nearinfrared light beam into the biceps of the dominant arm at specific wavelengths. Near infrared interactance uses a computerized spectrophotometer via solid state optics. For some devices you stand on a rotating platform for. Near infrared technology for measuring body fat was developed by the us. Government department of agriculture. The nir machine then uses this information along with age and activity level to estimate body composition.
This method uses the principles of light absorption and reflection more specifically transflectance and interactance to analyze body fat. 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 probe. Use the bello app to make the right choices everyday. This method uses the principles of light absorption and reflection to measure body fat.
