The present study aims to investigate the effects of purposeful and Omega-3 rich egg diets on blood metabolites in male aerobic athletes. Therefore, 45 athletes were randomly put into three groups of 15 and went under a 12-week exercise program with three sessions in a week. The exercise and non-exercise groups received on supplementary omega-3 egg every other day. However, the subjects in control group did not have any interventions. Blood sampling was conducted 24 hours before exercise and supplementary diet began from all three groups. In order to ensure normality of data distribution, Kolmogorov–Smirnov, dependent T, variance analysis and Tukey's post hoc tests were utilized. The results revealed that density of triglyceride and LDL in omega-3 supplemented groups with and without exercise decreased significantly compared to the control group. Moreover, density of HDL and cholesterol did not have a significant change. BMI decreased significantly in exercise group supplemented with Omega-3 compared to the supplemented group without exercise and the control group. Moreover, aerobic capacity of the aerobic exercise group supplemented with omega-3 was significantly higher than both other groups. Total plasma antioxidant capacity density and MDA increased in both exercise and non-exercise groups supplemented with omega-3; however, the increase was not significant. Findings demonstrated that the decrease in the levels of triglyceride, cholesterol and LDL along with the increase in the level of total plasma antioxidant capacity and MDA could be used as an efficient method for preventing damages induced by oxidation stress in endurance athletes and lower the risk of cardiovascular diseases.
