Abstract. The purpose of this study was examine to effect of different
exercise intensity (low, medium and high) on the salivary concentration
of Cortisol and DHEA in elite girl swimmers. 10 young swimmer girls were
voluntary selected as subjects. The subjects participated in a 6-week exercise
program. Exercise program divided to three time courses. Basic endurance
season in the first two weeks, Special endurance season in the second two
week and the hard exercise season in the last two weeks. Salivary samples
were collected at the end of each two weeks before and immediately after
exercise from the study group. Concentrations of salivary steroids determined
by using ELISA method .The findings of the research show that: exercise
with low, medium and high intensity does not have a significant effect
on the concentration of, cortisol, DHEA and the ratio of salivary DHEA:
C of elite girl swimmers p>0.05. There is no significant correlation between
concentrations with salivary cortisol after exercise with high and low
intensity p>0.05. But negative significant correlation was found between
concentrations with salivary cortisol after exercise with medium intensity
p<0.05. There is no significant correlation between concentrations with
ratio of salivary DHEA: C after exercise with low, medium and high intensities
p>0.05.In conclusion the result of this study show that salivary steroid
not affected by intensity of exercise.

EFEKTI RAZLIČITOG INTENZITETA VEŽBANJA
NA KONCENTRACIJU STEROIDA U PLJUVAČKI VRHUNSKIH
PLIVAČICA
Svrha ove studije je bila da se utvrde efekti različitih intenziteta vežbi
(nizak, srednji i visok) na koncentraciju Kortisola i DHEA u pljuvački
vrhunskih plivačica. 10 mladih plivačica su dobrovoljno izabrane za ispitanice.
Ispitanice su učestvovale u šestonedeljnom programu vežbi. Program vežbi
je bio podeljen u tri vremenska dela. Deo osnovne izdržljivosti je izvođen
u prve dve nedelje, deo specijalne izdržljivosti u druge dve nedelje,
i deo sa teškim vežbama u poslednje dve nedelje. Uzorci pljuvačke su
sakupljeni na kraju svake dve nedelje, pre i odmah posle vežbanja studijske
grupe. Koncentracija steroida u pljuvački je utvrđena korišćenjem ELISA
metoda. Rezultati istraživanja su pokazali da: vežbe sa niskim, srednjim
i visokim intenzitetom nemaju značajan efekat na koncentraciju kortisola,
DHEA i razmeru DHEA u pljuvački C vrhunskih plivačica p>0.05.
Nije postojala značajna korelacija između koncentracije sa kortisolom
u pljuvački nakon vežbanja sa visokim i niskim intenzitetom p>0.05. Ali
negativna značajna korelacija je pronađena između koncentracije sa kortisolom
u pljuvački nakon vežbanja sa srednjim intenzitetom p<0.05. Nije postojala
značajna korelacija između koncentracije sa razmerom DHEA u pljuvački:
C nakon vežbanja sa niskim, srednjim i visokim intenzitetima p>0.05. U
zaključku rezultati ove studije pokazuju da steroidi u pljuvački ne utiču
na intenzitet vežbanja.
