EFFECTS OF ACUTE PHYSICAL EXERCISE OF VARYING INTENSITY ON LIPID METABOLISM IN MIDDLE AGED MEN

Abstract

Aim. To investigate effects of acute physical exercise of varying intensity on lipid metabolism in middle aged men.Material and methods. Two bouts of physical exercise of moderate and high intensity were performed in 54 clinically healthy men aged 30-45 y.o. without obesity with subsequent assessment of lipid profile (total cholesterol, high density lipoprotein cholesterol, triglyceride levels, and atherogenic index). Effect of physical exercise on the lipid profile as studied both in the whole group and in subjects with and without insulin resistance.Results. Acute physical exercise of moderate and high intensity produced beneficial effects on lipid parameters (increase in cholesterol of high density lipoprotein level and reduction of atherogenic index). Increased intensity of physical exercise caused more prominent improvement of lipid profile in subjects without insulin resistance. However subjects with insulin resistance had weaker response to physical exercise than individuals without insulin resistance did and increased intensity of physical exercise did not cause significant improvement of lipid parameters in subjects with insulin resistance.Conclusion. Response to moderate or high intensive physical exercise may depend on baseline metabolic profile. It should be taken into account under development of preventive programs for modifying risk factors of cardio-vascular diseases and type 2 diabetes mellitus.
