The body fat percentage is a measure of fitness level since it is the only body measurement which directly calculates a persons relative body composition without regard to height or weight. For some devices you stand on a rotating platform for.
Sensors Free Full Text Dry Electrode Based Body Fat
Infrared body fat measurement. When operating the light wand sends a nearinfrared light beam into the biceps of the dominant arm at specific wavelengths. Government department of agriculture. The nir machine then uses this information along with age and activity level to estimate body composition. Near infrared interactance uses a computerized spectrophotometer via solid state optics. 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. 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.
This method uses the principles of light absorption and reflection more specifically transflectance and interactance to analyze body fat. The widely used body mass index bmi provides a measure that allows the comparison of the adiposity of individuals of different heights and weights. 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. Near infrared technology for measuring body fat was developed by the us. One potential low cost approach for obtaining direct measurements of body fat is near infrared nir interactance. Portable analyzers using nearinfrared interactance nir principle have been proposed for the direct measurement of percent body fat.
