[Correlation between biochemical indicators of physical fitness and age]

16 men in the average age of 23.7 years and 24 juniors in the average of 17 years, ice-hockey players, were investigated. A significant negative correlation between the physical fitness and indicators of lipoprotein metabolism were found. This correlation proved the significance of the intensity of physical activity as a factor decreasing the risk factors of atherosclerosis. Significantly higher levels of triacylglycerols and significantly lower HDL-cholesterol were found in men when compared with the juniors. The comparison of two age categories which were subjected to regular long-term physical activity of high intensity, proved the influence of the age of ice-hockey players who had been trained under the same conditions. Both quantitative and qualitative changes in lipoprotein metabolism proved the increase in atherogeneous risks with the increasing age. (Tab. 7, Ref. 14.)
