The aim of our observation was to measure selected anthropometric characteristics and to analyze actual body composition in children of younger school age from elementary schools in Prague. The group consisted of a total of 222 probands, boys (n-117) and girls (n-105) aged 8-11 years (average boy age = 9.0 +- 1.0 years, body height = 139.9 +- 8.6 cm, body weight = 32 +- 7.5 kg, BMI = 16.3 +- 2.4 kg.m-2).
Average age girls = 8.9 +- 0.9 years, body height = 137.3 +- 8.8 cm, body weight = 30.5 +- 7.3 kg, BMI = 15.9 +- 2.4 kg.m-2). The BIA 2000 M multi-frequency apparatus (whole-body bioim-pedance analysis) was used to analyze the body composition.
Children of younger school age showed higher TBW values - total body water (boys 65.5 +- 6.0%, girls 66.6 +- 6.5%), low body fat (boys 16.1 +- 2.4%, girls 16 , 5 +- 2.9%) and higher ECM/BCM coef-ficients (boys 1.0 +- 0.13, girls 1.02 +- 0.11). The authors draws, attention to the importance of monitoring other body composition parameters.
The percentage of fatty matter (FFM) and the share of segmental distribution of body fat and muscle mass on individual parts of the human body
