Abstract

ABSTRACT Background and objectives: The aim of this study was to investigate the effects of six months of aerobic exercise on lipid profile, inflammatory markers, and risk factors of cardiovascular disease in middle-aged obese women. Methods: Fifteen obese woman (age range: 35 to 45 years) with BMI of ≥30 Kg/m2 were enrolled via purposeful and convenience sampling. The participants were randomly divided into training (n=10) and control (n=5) groups. Blood samples (7 ml) were taken from all participants before the first training session and after the last training session. The women performed 60 minutes of aerobic exercise at 55-65% of heart rate reserve, three sessions a week, for six months. Data was analyzed using independent and paired t-tests and Mann-Whitney U and Wilcoxon tests at significance of 0.05. Results: After the six-month aerobic exercise, C-reactive protein, low-density lipoprotein, triglycerides, total cholesterol and high-density lipoprotein/total cholesterol decreased significantly. The exercise intervention also caused a significant increase in the concentrations of high-density lipoprotein and apolipoprotein A. Conclusion: Aerobic exercise can reduce the level of inflammatory markers associated with risk of cardiovascular disease and atherosclerosis. Keywords: Lipid profile, Inflammatory markers, Obese women, Apolipoprotein, Aerobic exercise.
