INTRODUCTION Physical exercise is the performance of some activity to develop or maintain physical fitness and overall health. It is often directed toward also honing athletic ability or skill. Frequent and regular physical exercise is an important component in the prevention of some of the diseases of affluence such as heart disease, cardiovascular disease, Type 2 diabetes, obesity and hypercholesteremia(1), (2). Serum lipid levels may be associated with age, gender, dietary habits and some primary genetic defects. Low cholesterol levels characterize some rare hereditary disorders such as abetalipoproteinemia, familial hypobetalipoproteinemia and chylomicrone retention disease. Furthermore, low plasma levels of TC, with or without hypertriglyceridemia-4 0-have been frequently described in a variety of disorders. The main metabolic benefits of regular physical activity are a rise in high density lipoprotein cholesterol (HDL-C) levels, a lowering of triglycerides (TG) and low density lipoprotein cholesterol (LDL-C) levels, and higher insulin sensitivity to fasting glucose. In addition, exercise training increases plasma clearance of postprandial lipoproteins, such as chylomicrons (3). Chylomicrons transport dietary lipids from the intestine into the systemic venous system. Endurance exercise also increases fat oxidation, enhances dietary TG turnover, and increases HDL-C concentrations (4).
