Changes in plasma lipid and apolipoprotein profiles were evaluated in 12 healthy, unfit subjects (VO2peak 39.1±2.8 ml·kg-1·min-1; 5 women, 7 men) at baseline and following endurance exercise training. The exercise protocol consisted of a 6-week endurance exercise training program (4–5 days week−1; 60 min·session-1; ≥65% HRmax). Subjects were randomly assigned to consume an egg- (n=6; 12 eggs·week−1) or no-egg (n=6; 0 eggs·week−1)-based, eucaloric, standardized diet for 8 weeks. Both diets were macronutrient balanced [60% carbohydrate, 30% fat, 10% protein (0.8 g·kg-1·day−1)] and individually designed for weight maintenance. Plasma lipids were measured twice within the same week at baseline and following exercise training. At baseline, subjects were normolipidemic with values of 163.9±41.8, 84.8±36.7, 60.6±15.4 and 93.1±52 mg dl−1 for total cholesterol, LDL cholesterol and HDL cholesterol and triglyceride concentrations, respectively. A two-way ANOVA was used to analyze diet and exercise effects and interactions. In both groups, endurance exercise training resulted in a significant 10% increase in HDL-C (P<.05), a 19% decrease in Apo B concentrations (P<.05) and reductions in plasma CETP activity (P<.05). Plasma LDL-C decreased by 21% (P=.06). No main effects of diet or interactions with plasma lipids or Apo B concentrations were observed. These data demonstrate that endurance training improved the plasma lipid profiles of previously unfit, normolipidemic subjects independent of dietary cholesterol intake from eggs.
