| Introduction Major risk factors for cardiovascular diseases (CVD) include hypertension, smoking, serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), low levels of high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG). Physical inactivity and reduced cardiorespiratory fitness contribute to the risk of CVD, whereas there is consistent, substantial, and strong evidence that physical activity is a deterrent for developing cardiovascular disease [1]. The aim of this study was to know what kind of exercise could be more effective to improve lipid profile in overweight people. Methods Ninety participants with overweight (18 ? 50 years; BMI > 25 and < 30 kg/m2) were randomized to one of the following groups: strength training (ST; n = 22), aerobic training (AT; n = 25), a combination of AT and ST (COM; n = 23), 3 times/wk for 24 wk, and control group (CG; n = 20). All of them in combination with diet restriction. The measurements took place for all subjects before training at weeks 1 to 4, and after 16 weeks of training in weeks 21 to 24. All groups were evaluated for changes in blood concentrations of lipoprotein-lipids, cardiovascular fitness, body composition, and dietary composition. Two way ANOVA with repeated measures was used to determine differences between moments (before and after intervention). The significant level was set at ?0.05. Results Lipid profile showed improvements in all groups. Triglycerides (TG) had a significant decreased in ST (23.53%; p<0.001) and AT (14.29%, p<0.05). AT, COM and CG significantly reduced total cholesterol (TC) 11.4%, 21.75% and 16.88% (p<0.01) respectively. Low-density lipoprotein-cholesterol (LDL-C) was significantly decreased in COM (16.15 %, p<0.001) and CG (14.7 %, p<0.001). Discussion The results of the present study are in agreement with recently reported results that showed improvements in lipid profile with aerobic training [2, 3], resistance training [4] and combination [5]. In summary the present study showed that all training methods may improve lipid profile. References 1. Blair, S.N., et al. Med Sci Sports Exerc (2001); 33:762-64. 2. Stensvold, D, et al.
