DETERMINING BODY COMPOSITION

摘要

A device and method of determining body composition are described, in particular for determining a body fat fraction. The method includes receiving predetermined parameters of a body, such as weight, height, and sex. At least one measured parameter of the body is received, e.g. from an accelerometer, for detecting physical activity of the body. Subsequently the body composition is calculated by processing said predetermined parameters and measured parameter. Surprisingly the body fat percentage can be accurately determined based on the formula: fat fraction = a + b * height^w + c * age^x + d * weight^y + e* gender + f * activity^z activity being a measured value indicative of the physical activity of the body.
