Abstract Increment of Lp (a) is a Coronary Diseases risk factor and evidences indicated that Lp(a) not been alter by exercise training. That is there correlation between physical activity and LP(a)? The aim of this Cross-sectional study was to compare of correlation between physicalactivity and LP (a) in selected groups of active; sedentary and with CAD men. EstimatedVO2max as a physical activity rating index estimated was based on non exercise predictionequations for VO2max. Fasting serum concentration of Lp (a) analysis withImmunoturbidimetric method. Pearson correlation equations between VO2max and Lp (a) ingroups are not significant. Therefore; Lp (a) not been alter by exercise training.
