Objective: Lipid profiles are one of the known predictors of cardiovascular diseases. Aerobic exercises are employed to reduce cardiovascular risk factors. The purpose of this research was to examine the effect of two types of aerobic exercise on lipid profiles and Castelli risk index in sedentary adult female subjects. Methods: Twenty sedentary healthy volunteer females aged 35 to 45 voluntarily participated in two types of endurance exercise for 8 consecutive weeks. Blood parameters including TC, TG, HDL, and VLDL and LDL/HDL, Chol/HDL ratios were analyzed. Results: No significant differences were found between the two types of training protocols on TC, TG, LDL, HDL, HDL to LDL and VLDL (P=0.885, 0.110, 0.607, 0.137, HDL to LDL, 0.90) levels. Both exercise types had significant effects on TC, LDL, HDL, Castelli risk index, and weight (P=0.0001, 0.0001, 0.006, 0.0001). However, no significant difference was found between the pre and post-test levels of TG and VLDL (p=0.46, 0.44), respectively. Conclusion: Aerobic exercise performed intermittently or continuously has a significant effect on reducing the Castelli risk indexes. In addition, both types of exercise are effective on weight reduction. Further research is needed to include other age groups.
