[Physical exercise and serum lipids].
The physical activity shows an inverse correlation with Ischaemic Cardiopathy, with evidence that lipids and lipoproteins blood levels are favourably modified by exercise. In this way, this study compared the different degrees of physical activity and the levels of blood lipids/lipoproteins, as well as the anthropometric and physiological variants. One hundred fifty seven non smoking males, aged 15 to 31 years old, average 21 years, were divided in two groups: G1 comprises 88 athletes individuals and G2, 69 non-athletes. The G1 individuals showed less corporal fat and better aerobic capacity than the G2 individuals. The levels of cholesterol, triglycerides, and the VLDL/cholesterol ratio were lower in the G1 individuals, as well as the risk rate 1 and 2, respectively the ratio of cholesterol/HDL cholesterol and LDL cholesterol/HDL cholesterol. There was no difference in both groups regarding the LDL and HDL cholesterol. In the G2 individuals the percentage of corporal fat had a direct correlation to the blood levels of triglycerides and VLDL cholesterol, and an inverse correlation to the HDL cholesterol blood level. Also, in this group there was a significative correlation to the risk rate 1 and 2. However, in G1 individuals the lipidic/lipoprotein levels were more favourable, which suggests a lower risk of developing Ischaemic Cardiopathy. Statistical analysis was obtained through "t"-Student, X2 and Spearman methods, with significance level of 0.05.
