Abstract. Our research included 60 male subjects aged 50 to 60,
30 of which made up the experimental group, and the remaining 30 made up
the control group. We studied the effects of a physical activity program
on the changes in volume and the subcutaneous fatty tissue of individuals
who had suffered myocardial infarctions (MI). The experimental physical
activity program was realized over a period of 21 days, and the activities
were divided into three parts: 1) gymnastics exercises, 2) walking along
health trails and 3) riding on a bicycle ergometer. The overall duration
of each daily exercise session was 45 minutes at the beginning and 60 minutes
at the end of the program. Ten variables were included in the research,
which covered the area of voluminosity and subcutaneous fatty tissue. We
calculated the basic descriptive parameters, and in order to determine
the differences between the groups at the initial and final measuring and
the differences between the initial and final measuring of each group,
we used the t-test. We used a multivaraite and univariate analysis of covariance
(MANCOVA/ANCOVA) to determine the actual effects of the physical activity.
The level of statistical significance was 0.05. All of the statistical
analyses were calculated with the help of the Statistica 6.0 statistics
package. The results from the final measuring have indicated that the realized
physical acitivity program had a positive effect on the changes in the
volume and subcutaneous fatty tissue of the subjects in the experimental
group, or in other words, that it led to changes in body mass (р= .000),
average thorax volume (р= .003), abdomen volume (р= .000), thigh volume
(р= .021), abdominal skin folds (р= .032) and thigh skin folds (р= .003).
Our research confirmed the positive effects of the program of physical
activity on changes in volume and subcutaneous fatty tissue in the sense
that it led to their decrease among people who had suffered myocardial
infarctions.
Key words: physical activity, myocardial infarction, voluminosity,

EFEKTI PROGRAMA FIZIČKIH AKTIVNOSTI NA
VOLUMEN
I POTKOŽNO MASNO TKIVO OSOBA SA INFARKTOM
MIOKARDA
Istraživanjem je obuhvaćeno 60 muškaraca hronološke starosti 50 do
60 godina, od kojih je 30 činilo eksperimentalnu, a 30 kontrolnu grupu.
Istraživani su efekti programa fizičkih aktivnosti na promene volumena
i potkožnog masnog tkiva osoba sa infarktom miokarda. Eksperimentalni
program fizičkih aktivnosti realizovan je ukupno 21 dan, a aktivnosti
su podeljene na tri dela i to: 1) gimnastičke vežbe, 2) hodanje na stazama
zdravlja i 3) vožnja na bicikl ergometru. Ukupno vreme svakodnevnog vežbanja
iznosilo je od 45 minuta na početku do 60 minuta na kraju programa. Istraživanjem
je obuhvaćeno 10 mera koje su pokrivale prostor voluminoznosti i potkožnog
masnog tkiva. Izračunati su osnovni parametri deskriptivne statistike,
a za utvrđivanje razlika između grupa na inicijalnom i na finalnom merenju
i razlika između inicijalnog i finalnog merenja kod svake grupe, primenjen
je t-test. Multivarijantna i univariajntna analiza kovarijanse (MANKOVA/ANKOVA)
upotrebljena je za utvrđivanje realnih ostvarenih efekata fizičkih aktivnosti.
Nivo statističke značajnosti bio je 0.05. Sve statističke analize izračunate
su pomoću statističkog paketa Statistica 6.0. Rezultati na finalnom merenju
pokazali su da je realizovani program fizičkih aktivnosti imao pozitivne
efekte na promene volumena i potkožnog masnog tkiva ispitanika eksperimetalne
grupe, odnosno da je doveo do promena kod telesne mase (r= .000), srednjeg
obima grudnog koša (r= .003), obima trbuha (r= .000), obima butine (r=
.021), kožnog nabora na trbuhu (r= .032) i kožnog nabora butine (r= .003).
Istraživanje je potvrdilo pozitivne efekte programa fizičkih aktivnosti
na promene volumena i potkožnog masnog tkiva u smislu njihovog smanjenja
kod osoba sa infarktom miokarda.
