Abstract
This study determined the influence of a single exercise bout on plasma lipoprotein phospholpids in I I hypercholesterolemic (HC) and 14 normocholesterolernic (NC) subjects. The exercise bout consisted of walking or jogging on a treadmill at 70% V02peak, until 500 kcals were expended. Diet was controlled during the testing period. Blood samples were collected 24 h before exercise and 24 h after exercise for lipid analysis. There were no statistically significant chang-es due to exercise in total phospholpid (PL), phosphatidylcholine (PC), and sphingomyelin (SPM) concentrations or the PC/SPM ratio in the HDL and LDL fractions (p < 0.05). The HC group did have significantly higher concentrations of total PL and PC in the LDL fraction (p < 0.05). There also were no statistically significant changes due to exercise in total cholesterol, HDL cholesterol, LDL cholesterol concentrations and lecithin-cholesterol acyltransferase activity. There was a significant decrease in triglvceride concentrations 24 h after exercise (p < 0.05). Exercise did not induce any significant plasma lipoprotein phospholipid concentration changes. There was not any significant differences between the response of HC and NC groups to exercise.
