Physical training and plasma intermediate density lipoprotein cholesterol levels in men with hypertriglyceridemia.
Plasma lipoprotein lipid levels including IDL cholesterol concentration, physical fitness parameters, and anthropometric data were measured in 10 men with primary hypertriglyceridemia during a 12 week program of moderate physical training. Reduced pulse rate at submaximal workload and increased work performed on the treadmill indicated that the men had increased their physical fitness during the training period. Body weight (-4.9%) and total skinfold thickness (-15.6%) fell during the training program. A characteristic fall (-23%) in plasma triglyceride levels was seen over the first 8 weeks training. Plasma IDL cholesterol concentration fell (-18%) after 2 weeks training but then rose after 8 weeks to levels which tended to be higher than baseline values. Our data suggest that regular physical exercise is more likely to raise levels of the "proatherogenic" IDL than to lower them in hypertriglyceridemic patients.
