ABSTRACTBackground and Objectives: Coronary heart disease has a direct correlation with plasma levels of Apolipoprotein B -ApoB- and low-density lipoprotein -LDL- and an inverse relationship with high-density lipoprotein -HDL- level. This study aimed at comparing effect of eight weeks of aerobic training with and without green coffee supplementation on serum ApoB level and atherogenic indices of overweight men.Methods:Thirty overweight men were randomly divided into two groups: training + green coffee supplementation -T+G; n=15- and training + placebo -T+P; n=15-. Participants in both groups performed aerobic training, three sessions per week for eight weeks. Initial exercise intensity was set at 50% of maximum heart rate but gradually increased to 75% of maximum heart rate in the last two weeks. In a single-blind design, the subjects in the T+G group received a 400 mg capsule of green coffee bean extract one hour before each exercise session. The T+P group received placebo at the same time. Paired sample t-test and independent t-test were used to compare intra-group and inter-group variations, respectively. All statistical analyses were performed using SPSS -version 22- at significance level of 0.05.Results:ApoB, LDL/HDL and total cholesterol/HDL decreased significantly in both groups. However, the changes were more notable in the T+G group compared tothe T+P group.Conclusion:The eight-week training program along with green coffee supplementation has positive effects on serum ApoB and atherogenic indices of overweight, inactive men. Therefore, it can be suggested as a non-pharmacological method of preventing cardiovascular disease
