Effects of Physical Activity and Diet on Lipemic Risk Factors for Atherosclerosis in Women

Abstract

Serum lipoproteins were studied in active and sedentary young women. The groups were matched for age, body weight, and blood pressure. A quantitative and qualitative evaluation of the diet was performed.

In spite of a higher intake of saturated fat and cholesterol, serum concentrations of triglyceride, total cholesterol, and low-density lipoprotein cholesterol in the active group were not significantly different from the controls.

Nevertheless, high-density lipoprotein cholesterol (HDL-C) levels were significantly higher in the active subjects even after covariance adjustment for nutrient intake; therefore, the HDL-C increase seems to depend on physical activity “per se” rather than on differences in diet.
