Abstract. The effects of aerobic dance were investigated on the
cardiovascular fitness and body composition of 46 women aged 20 to 25.
The experimental group was made up 26 female subjects, and the control
group numbered 20 subjects. The experimental program of the aerobic
dance lasted for a period of three months, with sixty-minute training
sessions three times a week. The aerobic dance part of each
workout lasted for 40 minutes, and involved high, low and moderate
impact segments. The cardiovascular fitness was evaluated by
means of the following parameters: resting heart rate, heart rate
under strain, systolic arterial blood pressure (mmHg), diastolic
arterial blood pressure (mmHg), the absolute value of maximal oxygen
uptake (l/min) and the relative value of maximal oxygen uptake
(ml/kg/min). Body composition was evaluated by means of the
following measurements: body height (cm), body weight (cm),
average thorax volume (cm), girth (cm), back skinfold (mm), abdominal
skinfold (mm). The basic descriptive statistics coefficients were
calculated for all the data from the initial and final measuring, along
with the Student t-test and multivariate and univariate covariance
analysis (MANCOVA and ANCOVA). There is a statistically significant
difference in the variables for cardiovascular fitness and body
composition between the initial and final measuring in the experimental
group and between the experimental and control group at the final
measuring. This study confirmed previous conclusions about significant
positive influence of the aerobic dance trainings on the changes in the
cardiovascular endurance and body composition parameters in young adult
women.

PROMENE KARIOVASKULARNOG FITNESA
I TELESNE GRAĐE ŽENA POD UTICAJEM
PLESNOG AEROBIKA
Istraženi su efekti modela plesnog aerobika na kardiovaskularni
fitnes i telesnu građu 46 žena starih od 20 do 25 godina.
Eksperimentalnu grupu sačinjavalo je 26 žena, a kontrolnu grupu
20. Eksperimentalni program modela plesnog aerobika realizovan je
tri meseca, tri puta nedeljno sa 60 minuta treninga. Sam plesni aerobik
na svakom treningu vežban je 40 minuta sa smenjivanjem high, low and
moderate tipom naprezanja. Kardiovaskularni fitnes je procenjen sa
sledećim parametrima: puls u miru, puls u opterećenju, sistolni
arterijski krvni pritisak (mmHg), dijastolni arterijski krvni pritisak
(mmHg), apsolutna vrednost maksimalne potrošnje kiseonika (l/min) i
relativna vrednost maksimalne potrošnje kiseonika (ml/kg/min). Telesna
građa procenjena je merama: telesna visina (cm), telesna težina
(kg), srednji obim grudi (cm), obim struka (cm), kožni nabor ledja (mm)
i kožni nabor trbuha (mm). Za sve podatke sa inicijalnog i finalnog
merenja izračunati su osnovni koeficijenti deskriptivne statistike,
Studentov T-test i multivarijantna i univarijanta analiza kovarijanse
(MANOVA i ANOVA). Između inicijalnog i finalnog merenja postoji
statistički značajna razlika na varijablama kardiovaskularnog fitnesa i
telesne građe žena kod eksperimentalne grupe, i između eksperimentalne
i kontrolne grupe na finalnom merenju. Ovo istraživanje je potvrdilo
već postojeće zaključke o značajnom pozitivnom uticaju plesnog aerobnog
treninga na promene u kardiovaskularnoj izdržljivosti i parametrima
telesne građe mladih žena.
