The Effect Of Omega-3 Supplementation And Aerobic Exercise On Cardiovascular Risk Factors Lipid Profile Of Men Elderly

Abstract Background & aim: The purpose of this study was to determine the effect of supplementation with omega-3 and 8 weeks of aerobic exercise on cardiovascular risk factors - vascular lipid profile in elderly men, respectively. Methods: In this present quasi-experimental study, 36 non athletic elderly men with the age range of 37/3 ± 37/57 years of age from Genaveh, Iran were randomly selected and divided into 4 groups of 9 (training + omega-3 supplements, training + placebo, omega-3 supplements and placebo) groups. Aerobic exercise program for 8 weeks, 3 sessions per week, term (30 to 45 minutes) and intensity of 55 to 70% Maximum heart rate was performed. Daily intake of omega-3 supplement was 2000. After 14 hours of fasting, blood samples before and 48 hours after the last study session were conducted. For data analysis, kolmogorov -smirnov-test, t-dependent, one-way ANOVA was used (p≤0/05). Results: After 8 weeks of training, TC levels of omega-3 supplements, omega-3 supplements, aerobic exercise and aerobic exercise with placebo significantly decreased (p≤0/05). But they were not significantly different in the placebo group (p≥0/05). Serum TG levels in groups supplemented with omega-3, aerobic training, supplementation with omega-3 a significant reduction was found (p≤0/05), but in the placebo group and aerobic training placebo, the reduction was not significant (p ≥0/05). Amounts of LDL-C were not significant in various groups (p ≥0/05). Levels of HDL-C in aerobic training, supplementation of omega-3 and aerobic training + placebo were significant (p≤0/05), but the omega-3 supplement and placebo groups showed no significant change (p ≥0/05). Changes in TC / HDL-C in the supplemental omega-3, aerobic training, supplementation of omega-3 and aerobic training + placebo a significant reduction was found (p≤0/05), but in the placebo group, no significant change was observed (p ≥0/05). Conclusion: Considering that aerobic training alone and omega-3 supplementation alone resulted in a significant reduction in cardiovascular risk factors - are cardiovascular, aerobic exercise and the intake of omega-3 supplements can be beneficial in preventing and reducing these diseases.
