Abstract

INTRODUCTION. The causes for the observed interpopulational differences in the fat level may be many. These include lifestyle, physical activity, ethnic, age, sex, but also the type of technique used for measuring body composition. The aim of the study was to compare the percentage of body fat content in young, non-obese men and women by using using the bioimpedance (with various electrode configurations) and near-infrared interactance.
MATERIAL AND METHODS. The study group was consisted of 69 healthy, non-obese, young people (52 women of mean age 24.07 ± 1.47 yrs; 17 men of mean age 24.23 ± 1.418 yrs). Three bioimpedance technique (BIA) were used to evaluate of body fat: a STA/BIA RJL - Akern 101/S tetrapolar version hand-to-foot electrodes; a Soehnle Body Balance Comfort F5 bipolar version footto- foot electrodes; an Omron BF 306 bipolar version hand-to-hand electrodes and near-infrared interactance technique (NIR): a FUTREX 6100 A/ZL. Body mass index and waist to hip ratio indices were also analyzed.
RESULTS. Percent body fat determined by BIA tetrapolar version hand-to-foot electrodes was significantly related to these determined by other methods assessing of fatness (women: R = 0.70-0.75; men: R = 0.55-0.86). Significant differences in percent body fat measured using the test methods occurred in both sexes (the Kruskal-Wallis test, women: H = 70.49; p = 0.0005, men: H = 36.07; p = 0.0005). The highest average value of percent body fat was obtained using the BIA version hand-to-foot electrodes technique (women: 29.22%, men: 22.72%), the lowest using the NIR method (women: 23.82%, men: 12.62%) and the observed differences are 5.4% in women and 10.1% in men.
CONCLUSIONS. All of these investigated methods body composition measurement may be used in the assessment of percent body fat content in young, non-obese people, but can not be used interchangeably.
