Effect of moderate physical training on serum lipids and lipoproteins.

Total cholesterol, triglycerides and HDL-, HDL2-, HDL3-cholesterol were evaluated in 81 subjects, 49 of them practised moderate physical activity, 32 were controls. Total cholesterol and triglycerides were evaluated enzymatically. The Abell method was applied to analyse HDL-cholesterol and the HDL3 subclass. A significant difference was observed between the plasmatic triglycerides of the active group and the control, indicating that even moderate physical activity can be associated with lower concentrations of triglycerides. The correlation coefficients calculated for the HDL-cholesterol and the HDL2-cholesterol subclass, respectively, with some anthropometric and physiological variables were, in most of the cases, not significant. The highest number of significant correlations was found in the HDL3-cholesterol subclass, but in that of the control group only.
