Abstract

Introduction: High postprandial triglyceride levels and obesity are associated with coronaropathy, and influence the pathogenesis and progression of atherosclerosis. Objective: To evaluate the effect of immediate acute physical exercise on postprandial hyperlipaemia in individuals with central obesity. Methods: Study included sedentary, normolipidemic individuals aged 18 - 30 years, with waist circumference >80 in for women and >94 for men. The physical exercise was performed for 45 minutes with 55% - 60% of the heart rate reserve. Triglyceride level tests were performed after fasting, and at time intervals of 1h and 3 h after lipid overload, a week before and immediately after a session of physical exercise. Results: Thirty-six individuals were evaluated (mean age 23.74 ± 4.05 years, 88.2% women, BMI = 28.4 ± 3.4). Fasting and post-prandial triglyceride levels were similar before and after the exercise (p = 0.87). A smaller rise in triglyceride levels was observed in the 1st hour in obese individuals (5%) compared with over-weight individuals (21%) p = 0.001. Conclusion: In individuals with central obesity, moderate intensity physical exercise performed immediately before lipid overload does not reduce the hyperlipidemic peak.
