• This study was designed to test whether an exercise program is additive to diet counseling in lowering elevated blood cholesterol levels. From a screened population of 1024 subjects, we randomized 66 predominantly female subjects to two intervention groups: diet counseling and diet counseling with exercise. Subjects were selected who had elevated levels of serum low-density lipoprotein cholesterol, an average or low fitness level, and a diet high in saturated fat and cholesterol. After 26 weeks of intervention, 51 subjects exhibited significant decreases in serum levels of cholesterol, high-density lipoprotein cholesterol, triglycerides, and low-density lipoprotein cholesterol. The addition of exercise to diet counseling resulted in improved aerobic capacity, losses of body fat and weight, and further nonsignificant decreases in serum cholesterol and low-density lipoprotein cholesterol levels. Since these results differ from data acquired in individuals with normal to borderline serum cholesterol levels, further studies appear indicated in hypercholesterolemic subjects, especially in women.
