Abstract. The aim of this research was to establish whether there are statistically significant differences among three groups of individuals that exercise actively, concerning the indicators of aerobic capacities, and in relation to their age. The sample of individuals consisted of 72 women in total (aged 20-49) who exercised actively in the World Class fitness club, Novi Sad. The individuals were grouped into three sub-samples according to their age. The first sub-sample consisted of individuals aged 20-29 (N=22), the second sub-sample of individuals aged 30-39 (N=28) and the third one of individuals aged 40-49 (N=22). The application of a multivariate and univariate analysis, as well as the t-test for independent samples, established statistically significant differences of the indicators of aerobic capacities on the quantitative level among all three groups of females and in favor of the younger women. The application of a univariate and multivariate analysis of variance, followed by the t-test for independent samples, which showed that there are statistically significant differences between aerobic capacity indicators at the quantitative level among the three groups of women and that they are in favor of the younger women. Those differences can be noted in the variables of peak heart rate, heart rate at peak oxygen uptake, relative oxygen uptake, duration, and speed test runs at peak oxygen uptake. Based on these results it can be concluded that there are significant differences in the aerobic capacity of women belonging to different age groups on the quantitative level. The women belonging to the group aged 20-29 showed better aerobic performance than the other two analyzed groups, aged 30-39 and 40-49.
Key words: aerobic capacity, individuals, age, aging.
RAZLIKE U AEROBNOJ SPOSOBNOSTI KOD FIZIČKI AKTIVNIH ŽENA U ODNOSU NA STAROSNU DOB
Cilj ovog istraživanja bio je utvrditi da li postoje statistički značajne razlike između tri grupe fizički aktivnih žena u pogledu indikatora aerobnih sposobnosti u odnosu na starosnu dob. Za uzorak ispitanika odabrane su 72 ispitanice, stare 20-49 godina, koje su aktivno vežbale u fitnes klubu "World Class" u Novom Sadu. Ispitanice su bile podeljene u tri poduzorka u odnosu na starosnu dob. Prvi poduzorak činile su ispitanice starosne dobi 20-29 (N=23), drugi 30-39 godina (N=28) i treći ispitanice starosti 40-49 (N=21) godina. Primenom univarijatne i multivarijatne analize varijanse a potom t testa za nezavisne uzorke ustanovljene su statistički značajne razlike na kvantitativnom nivou u indikatorima aerobne sposobnosti, između sve tri posmatrane grupe ispitanica, a u korist mlađih ispitanica u varijablama Maksimalna srčana frekvenca, Srčana frekvenca pri maksimalnoj potrošnji kiseonika, Relativna potrošnja kiseonika, Dužina trajanja testa i Brzina trčanja pri maksimalnoj potrošnji kiseonika. Na osnovu dobijenih rezultata može se reći da postoje značajne razlike u aerobnim sposobnostima žena različite starosne dobi na kvantitativnom nivou. Ispitanice koje pripadaju grupi 20-29 godina starosti pokazale su bolju aerobnu efikasnost u odnosu na druge dve analizirane grupe (30-39 i 40-49 godina starosti).
