ABSTRACT
Profile and standards for the diagnostics of percent of body fat and muscles were defined on a sample of 1924 women from the Republic of Serbia, aged 18.0 to 69.9, where the body structure of subjects was measured by applying multichannel segmental bioimpedance. Total sample was divided into six age groups, for the purpose of the definition of standard with regards to age. When it comes to body fat percentage results have shown that the average value of the total sample was 28.51±9.26 %, and between the range of 23.81 and 39.94 % for age groups 18.0-19.9 yr and 60.0-69.9 yr, respectively. Regression analysis results have shown that the constant of body fat percentage increase by trend of 3.417 % per decade, and that 25.1 % of mutual variance trend was explained by the model, with prediction error of 4.55 %. With regards to the percentage of skeletal muscles in the body, the results have shown that the average value of the total sample was 39.30±5.25 %, and within the range of 42.25 to 32.58 % for age groups 18.0-19.9 yr and 60.0-69.9 yr, respectively. Regression analysis results have shown that the constant of the skeletal muscles decrease by tend of -2.016 % per decade and that the model explained 23.8 % of mutual variance trend with prediction error of 8.08 %.
RESUMEN
El perfil y estándares para el diagnóstico del porcentaje de grasa corporal y masa muscular fueron definidos en una muestra de 1924 mujeres de la República de Serbia, con edades comprendidas entre 18,0 y 69,9 años, donde la composición corporal de los sujetos fue medida por bioimpedancia segmentaria multicanal. La muestra fue dividida en seis grupos, con el propósito de definir los estándares respecto a la edad. Respecto al porcentaje de grasa corporal los resultados han mostrado que el valor promedio de la muestra fue de 28,51±9,26 %, y entre los rangos de 23,81 y 39,94 para los grupos de edad de 18,0-19,9 años y 60,069,9 años, respectivamente. Los resultados del análisis de regresión mostraron que la constante del porcentaje de grasa corporal aumentó 3,417 % por década, y que un 25,1 % de la varianza fue explicada por el modelo, con un error de predicción de 4,55 %. Con respecto al porcentaje de masa muscular, los resultados han mostrado que el valor promedio de la muestra fue de 39,30±5,25 %, y entre los rangos de 42,24 y 32,58 para los grupos de edad de 18,0-19,9 años y 60,0-69,9 años, respectivamente. Los resultados del análisis de regresión han mostrado que la constante de masa muscular decreció -2,016 % por década y que el modelo explicó 23,8 % de la varianza con un error de predicción de 8,08 %.
