Effects of an eight-week exercise program on parameters of the lipid profile of female students

Abstract

Increased lipid levels are one of the major risk factors for the development of cardiovascular diseases. The aim of the current study was to evaluate the effect of short-term (8 weeks) aerobic exercise of moderate to vigorous intensity on lipid profile in young healthy females. 27 female students (mean age 20.5 ± 1 year) completed 8 weeks of aerobic training that included two exercise sessions of continuous aerobic activity of moderate intensity (running 35-60 min) and one exercise session with interval training of vigorous intensity. Intervention aerobic capacity and lipid profile were examined before and after the exercise. Exercise intervention has caused a decrease of low density lipoprotein levels per 9.8% (from 2.52 ± 0.47 to 2.27 ± 0.53 mmol/L; p < 0.001) and significant improvement of high density lipoprotein (HDL) levels per 22.7% (from 1.29 ± 0.24 to 1.59 ± 0.24 mmol/L; p < 0.001), total cholesterol/HDL ratio per 17.2 % and aerobic capacity (VO 2 ma x) per 3.8 % (43.9 ± 3.7 to 45.56 ± 3.63 mLO 2 /kg/min). The results support the hypothesis that a short-term aerobic exercise intervention of moderate to vigorous intensity may have significant effects on blood lipid profile in young healthy females.

Uvod:Pove}ani nivo lipida je jedan od zna~ajnih faktorarizika za razvoj kardiovaskularnih bolesti. Cilj ovog istra `i -vanja je da se procene efekti kratkog (8 nedelja) aerobnogve`banja, umerenog do visokog intenziteta, na lipidniprofil.Metode:27 studentkinja (prose~ne starosti 20,5 ± 1 godi -na) je izlo`eno osmonedeljnom aerobnom ve`banju koje sesastojalo od treninga kontinuirane aerobne aktivnosti ume -renog intenziteta (tr~anje 35–60 min) dva puta nedeljno iintervalnog treninga visokog intenziteta jednom nedeljno.Lipidni profil je odre|en pre i posle programa ve`banja. Rezultati:Program ve`banja je doveo do smanjenja nivoa»lo{eg« holesterola za 9,8% (od 2,52 ± 0,47 na 2,27 ±0,53 mmol/L; p < 0,001), zna~ajnog pove}anja »dobrog«holesterola (HDL) za 22,7% (od 1,29 ± 0,24 na 1,59 ±0,24 mmol/L; p < 0,001), odnosa ukupnog holeste -rola/HDL za 17,2% i pobolj{anja aerobnog kapaciteta(VO2 max) za 3,8% (od 43,9 ± 3,7 na 45,56 ± 3,63mLO2/kg/min). Zaklju~ak:Rezultati istra`ivanja podr`avaju hipotezu dakratkotrajno aerobno ve`banje od umerenog do visokogintenziteta ima zna~ajan uticaj na lipidni profil mladih,zdravih, `enskih osoba.
