Abstract

Physical activity is inversely associated with coronary artery disease (CAD) incidence. Aerobic exercise at intensities above the anaerobic threshold has a favorable effect on plasma lipids and lipoproteins. The effects of aerobic exercise on plasma lipids and lipoproteins at very low work intensities (subanaerobic threshold) have not been reported. Changes in plasma lipid and lipoprotein values in five hypertriglyceridemic subjects are assessed before and after 90-minute submaximal exercise testing at 40% VO(2max). Group changes after exercise include an increase in total cholesterol (C) (2.5%); low-density lipoprotein (LDL)-C (6%); and HDL-C (9%); with decreases in very low-density lipoprotein (VLDL)-C (5%); total-T (20%); very low-density lipoprotein (VLDL)-TG (26%); low-density lipoprotein (LDL)-TG (11%); and high-density lipoprotein (HDL)-TG (30%). These findings are similar to those in normolipidemics undergoing acute exercise bouts at the anaerobic threshold. Although differences in lipid metabolism in response to acute exercise in normals and hypertriglyceridemics may exist, subanaerobic intensities of exercise may favorably affect plasma lipids and lipoproteins.
