Abstract. The evaluation of body composition was performed on a sample of 152 female participants, aged 20-76, from Novi Sad, by applying a battery of 4 tests and an analyzer of bioelectrical impedance MALTRON 920. The participants were divided into five subsamples according to their age, one group for every decade. The division of participants according to their age groups was done in accordance with some earlier studies. Statistical methods, the Univariate (ANOVA) and multivariate (MANOVA) analyses of variance, determined that there were some statistically significant differences between all the age groups, not only in terms of individual, but also in terms of the mutual system of variables. The differences between the pairs of the majority of age groups were established by using the t-test and it confirmed the results of ANOVA and MANOVA methods.
Key words: Body composition, age group, ANOVA, MANOVA
ANALIZA PROMENA U SASTAVU TELA KOD ŽENA RAZLIČITIH STAROSNIH GRUPA
Procena sastava tela je sprovedena na uzorku od 152 ispitanice starosti 20-76 godina iz Novog Sada, primenom baterije od četiri testa i analizatora bioimpedanse MALTRON 920. Uzorak ispitanica je podeljen na pet sub-uzoraka, u odnosu na njihove godine, po principu jedne grupe za svaku dekadu i u skladu sa određenim ranije sprovedenim istraživanjima. Primenom statističkih metoda univarijantne (ANOVA) i multivarijantne (MANOVA) analize varijanse utvrđene su određene statistički značajne razlike između svih starosnih grupa, ne samo u individualnom, već i u zajedničkom sistemu varijabli. Razlike između parova većine starosnih grupa utvrđene su primenom t-testa, što je potvrdilo rezultate metoda ANOVA i MANOVA.
