“…For this purpose, whole-body human impedance method can lead to misinterpretations if the state of hydration of fat-free mass is not 73 %. Therefore, the use of bioelectrical impedance vector analysis allows identification of changes in hydration status and mass of soft tissues, by solely considering impedance components independently of predictions in fluid volumes or assumptions of constant chemical composition of the fat-free body [26].…”

The study of body composition can be used to verify one's state of fitness and the effectiveness of a training program. The aim of the study is to present the integration of this method for total and segmental assessment of body composition. 59 elite soccer players (aged 22.47 ± 5.58 years, height 1.81 ± 0.08 m) were enrolled for the study. Before the season and after 50 days of training, a body composition assessment was carried out. For the measurement of fat mass, folds of skin in 8 different regions were used. To evaluate cell mass and hydration status, bioimpedance with both whole-body and vector methods was used. The localized evaluation was performed by assessing bioelectrical values of the quadriceps, hamstrings and calf. Data before and after 50 days of soccer training were compared (t test for paired data). The values of body composition were within the normal range for the sample. After 50 days of training, there was a significant increase in BMI mainly dependent on extracellular water. The fat did not undergo quantitative changes but only a change in distribution occurs. Lower limb muscles showed an increase in the amount of water more significant than the total body assessment. An integration of fat and fat-free mass in athletes allows us to determine different adaptations to training methods. The assessment of body segments under more stress by physical training provides more specific information than the total body assessment in athletes. This method could evaluate a peripheral status of hydration and cellular mass.

“…Bioimpedance analysis models for calculation of extracellular resistance and prediction of whole body extracellular water volume have been validated using deuterium oxide [5,[26][27][28] and bromide dilution techniques. With bromide dilution, considered the gold standard for V ECF assessment, whole body V ECF is determined from bromide concentrations in blood plasma following solution ingestion [19,28].…”

Abstract-We investigated electrical bioimpedance as a potential measurement modality to assess residual-limb volume change in lower-limb amputees. Four strip electrodes were positioned across the anterior lateral to posterior lateral aspects of the proximal lower leg or residual limb such that the outer pair applied current and the inner pair sensed voltage. A commercial bioimpedance analyzer supplied current at 50 frequencies between 5 kHz and 1 MHz and then used a wellvalidated model to determine fluid resistance. From these data, extracellular fluid volume (V ECF ) could be estimated. Bench test evaluation showed the instrument to have a root-meansquare error of less than 0.014% over a 1 h interval. Tests of subjects who had been transtibial amputees for at least 2 yr showed V ECF changes from postural adjustments well outside the instrument error and normal minute-to-minute biological variability. The rate of V ECF change while standing with the prosthesis donned was greater for diabetic subjects than for nondiabetic subjects. Bioimpedance analysis may have use in prosthetics research, where comparing residual-limb volume at different time points or under different treatment conditions is of interest.

“…Así, la composición corporal total es determinada en gran medida por la impedancia de los brazos y las piernas (16,38). La BI segmentaria (técnica manos-pies) podría superar estas limitaciones porque con ella se estima de forma independiente la composición de cada segmento y luego la composición corporal total (14,34). Sin embargo, estudios efectuados con BI segmentaria utilizando una o varias frecuencias de corriente eléctrica han reportado limitaciones de la técnica para calcular la composición corporal de personas obesas (8,36,37).…”
