Abstract: | This study provides values of anthropometric measurements and specific impedance, for a sample of 104 adults. The hypothesis
that the body composition can be estimated more accurately from measurements of lengths and impedance values of the body segments
than from the whole body was tested. The impedance of upper and lower extremities (arm and leg) and trunk were used to compute
estimates of body composition parameters (FFM, FM, %F, TBW, ECW). The results were compared with those estimated by the impedance
of the whole body. These comparisons demonstrated that significative differences resulted from body composition obtained by
segmental impedance and by the whole body. |
