Effects of Supplementation and Training on Ameliorating Lipid Profiles and Protection against Coronary Artery Disease; an Experimental Study

The use of antioxidants may reduce the harmful effects of radicals during exercise and extreme sports. The Current study aimed to investigate the effect of this supplement on the lipid profiles in exercise-induced muscle injury. In this experimental study, 64 Wistar rats were randomly divided into four groups of control, exercise, exercise + Resveratrol (REV) and REV. After a week of adaptation, endurance and acute exercises were conducted in a motor driven treadmill, followed by using a training protocol in which running speed was gradually elevated until 19 weeks of age. Finally, the levels of cholesterol (CHO), triglycerides (TG), low-density lipoproteins (LDL), high-density lipoproteins (HDL), and very low-density lipoproteins (VLDL) were compared between the groups. There was no statistically significant difference in CHO plasma level between the studied groups after acute and endurance exercises. There was a significant increase in the level of TG in the exercise group (p = 0.001) and the exercise + REV (p = 0.004) group after acute and endurance exercises. After the implementation of the endurance and acute exercises none of the studied groups had statistically significant changes in HDL plasma level. There was a significant decrease in LDL plasma levels in the exercise (p = 0.007) and the exercise + REV (p = 0.01) groups. After performing endurance protocol, VLDL plasma levels increased significantly in the exercise (p = 0.001) and the exercise+ REV (p = 0.005) groups in comparison with control group. Based on the findings, there was no difference in the level of CHO and HDL between the training groups, REV and control groups. However, both endurance exercise and acute exercise trainings resulted in an increase in TG and VLDL levels and decrease in LDL level, compared with the control group.
