Abstract/OtherAbstract:
The purpose of this study was to determine the effects of exercise intensity on lipid and lipoprotein metabolism. Concentrations of triglyceride, cholesterol, high-density lipoprotein cholesterol (HDL-C) and its subfractions (HDL2-C and HDL3-C), low-density lipoprotein cholesterol, very-low-density lipoprotein cholesterol, and apolipoproteins A-I, A-II, and B were measured. Ten well-trained runners completed treadmill exercise on two different occasions: a high-intensity session at 75% maximal oxygen consumption lasting 60 min and a low-intensity session at 50% maximal oxygen consumption lasting 90 min. Energy expenditure for each session was equal. Fasted blood samples were obtained 24 h before, immediately before, immediately after, and 1, 24, 48, and 72 h after each exercise session. No significant differences were found for the blood variables across time or between treatments. However, HDL-C and HDL2-C were slightly elevated on the days after each treatment. These results suggest that acute exercise sessions lasting less than 90 min, regardless of intensity, do not elicit plasma lipid, lipoprotein, and apolipoprotein changes in men who are habitually physically active and have high initial concentrations of HDL-C.
