title: Associations of lecithin: cholesterol acyltransferase (LCAT) mass concentrations with exercise, weight loss, and plasma lipoprotein subfraction concentrations in men.
abstract: The relationships between plasma lecithin:cholesterol acyltransferase (LCAT) mass concentrations and lipids, apolipoprotein, and lipoprotein subfraction concentrations were studied in men assigned at random to a one-year exercise program (n = 48) and to a sedentary control condition (n = 31). Exercise training did not significantly affect mean concentrations of LCAT-mass. Moreover changes in LCAT within the exercise group were unrelated to distance run and weight loss. The baseline data and the one-year change data showed consistent positive correlations between LCAT concentrations and total cholesterol, low density lipoprotein cholesterol, very low density lipoprotein cholesterol, and apolipoprotein B concentrations, and consistently weak correlations between LCAT concentrations and high density lipoprotein (HDL)-cholesterol, HDL2, and apolipoprotein A-I concentrations. The strong correlation between LCAT and total cholesterol may account for LCAT's relationships with lipoprotein subfractions, apolipoprotein B and other lipoprotein cholesterol concentrations.
