MADIC, Dejan M. et al. Calcaneus quantitative ultrasound and Body Composition in Preschool Children: Physical Activity Consideration. Int. J. Morphol. [online]. 2017, vol.35, n.4, pp.1249-1253. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022017000401249.

The aim of this research was to determine the difference in Calcaneus quantitative ultrasound (QUS) and body composition according to physical activity in preschool children. We recruited 296 healthy children (112 girls and 184 boys) from different kindergartens in Vojvodina, Serbia. Children were evaluated for body composition. Quantitative ultrasound (QUS) measurements of the heel were performed using the Speed of sound, Broadband Ultrasound Attenuation, Quantitative Ultrasound Index and Estimated bone mineral density for further analysis. Furthermore, children were divided into three groups according to physical activity. Apart from the differences in Body fat % and body mass, there were no significant group differences for BMI, waist circumference and abdominal skinfold (p>0.05). The ANOVA showed significant differences (p<0.05) in all QUS measurements between three different intensities of physical activity. The results show that Body Mass and Body fat % were important predictors that discriminate children according to physical activity. Moreover, the results show that beside BMI and Body fat %, all calcaneus QUS measurements showed differences according to physical activity. In conclusion, our study showed differenses in all calcaneus QUS measurements according to physical activity level.
