Abstrakt		Background. The aim of this study was to analysed on the basis of anthropometric measurements the composition of human body, to establish the differences between sexes and changes with growth in contribution of tissue masses which form body mass. Methods and results. We have used anthropometrical five way fractionation method. Tissue masses are defined anatomicaly. The sum of skin, adipose, muscle, bone and residual mass obtain total body mass. Our research involves cross-sectionaly measured healthy population of 281 male and 297 female adolescents from secondary schools and 325 male and 344 female students (freshmen). The differences between predicted and actual mass are as expected. Differences between sexes are best seen in higher contribution of muscle mass in male and adipose mass in female. Changes with ages coincide with the events in adolescence period. In boys we found the increasing values in muscle mass in all age period and decrease in 16 year old in adipose mass. In girls all tissue masses are increasing till the age of 16. After this year all masses decrease except adipose mass. Conclusions. The analyses shows the differences between sexes and between age groups in body composition. The results could serve us as the basis for future research work and as the basis for comparisons with the results of other researches.
Izvleček		Izhodišča. Namen raziskave je bil analizirati na osnovi antropometričnih meritev sestavo človeškega telesa ter ugotoviti spolne razlike ter spremembe z dozorevanjem z udeležbi velikih tkiv, ki tvorijo telesno maso. Metode in rezultati. Uporabili smo antropometrično petdelno delitveno metodo. Tkivne mase so določene anatomsko. Vsota vseh izračunanih mas: kože, mišičja, maščevja, kosti in ostanka določa celokupno telesno maso. V raziskavo je bila s presečno metodo zajeta zdrava populacija 281 dijakov in 297 dijakinj v starosti od 14 do 18 let ter 325 študentov in 344 študentk prvih letnikov. Razlike med izmerjeno in izračunano telesno maso so v pričakovanih mejah. Spolne razlike so najbolj vidne v višji udeleženosti mišične mase pri moških in maščobne mase pri ženskah. Starostne spremembe sovpadajo z dogodki v adolescentnem obdobju. Pri dečkih beležimo naraščanje mišične mase v celotnem starostnem obdobju in upad količine maščevja pri 16. letih. Pri deklicah tkivne mase naraščajo do 16. leta, po tej starosti pa razen maščobne ostale tkivne mase upadajo. Zaključki. Analize sestave telesa so pokazale spolne in starostne razlike v udeleženosti posameznih tkivnih mas. Rezultati nam lahko služijo kot osnova za nadaljnje delo in kot primerjava z rezultati drugih avtorjev.
