High-Density Lipoprotein, Lipid, and Carbohydrate Metabolism during Increasing Fitness

Abstract

Eleven unfit bank executives in sedentary employment exercised daily for 10 weeks according to the Canadian Air-Force 5BX Exercise Programme. Over this period no changes were observed in the glucose or insulin responses to a standard breakfast or to intravenous glucose, or in the glucose response to intravenous insulin. There was a significant reduction in high-density-lipoprotein cholesterol, but total plasma triglyceride and cholesterol levels were unaffected by exercise.

High density lipoproteins and exercise.

“…The disparity in results has been attributed to the various methods used for estimation of the HDL level, the Phospho-tungstic Acid/Magnesium Chloride Method giving different values from the well-proven Heparin/ Manganese Chloride Method (Thompson and Trayner, 1979;Warnick and Albers, 1978) which we have used in our study. The HDL level in our patients with PVD would be regarded as being low when compared to the results (using the Heparin/Manganese Method) of some workers (Zilcher et al, 1979;Moore et al, 1979) but normal compared to those of other workers Wood et al, 1979). There was no significant difference between the HDL levels of the Vascular and Control groups.…”
