ATHEROSCLEROTIC RISK IN ADOLESCENTS WITH DIFFERENT VO2MÁX LEVELS

Abstract

Introduction: Prospective studies demonstrated that, in adults, high cardiorespiratory fitness takes the atherosclerotic disease reduction. In other hand, differently of the adult population, there are few and contradictory studies about the atherosclerotic risk factors associated with the cardiorespiratory fitness in children and adolescents. Objective: To compare the atherosclerotic risk factors in male adolescents with different VO2máx levels. Methodology: The sample was composed for 121 adolescents with age between 12 to 16 years old. The VO2máx was measured by 20 meters Léger test. The blood pressure was measured using a sphygmomanometer of mercury column. The total cholesterol, HDL and triglycerides were determined through the enzymatic-colorimetric method. LDL and VLDL were than calculated. In the statistical analysis were used the ANOVA's and Tukey post hoc, with p<0.05. Results: Significant differences were detected for the VLDL-C (F=5.04; p=0.008) and triglycerides (F=5.17; p=0.007) between the groups. In relation to the post hoc test, the VLDL-C and triglycerides presented by the males with low VO2má were significantly greater than the values found in your pairs with high and moderate VO2máx . Conclusion: Our results x demonstrated that the adolescents this sample with high VO2máx levels present lesser atherosclerotic risk compared to your pairs with low VO2máx , mainly for the VLDL-C and triglycerides concentrations.
