Abstract
GARCIA-CARDONA, Diana M; A. NIETO, Olga and LANDAZURI, Patricia. Effect of exercise in HDL subpopulations, lecithin-cholesterol acyltransferase enzyme (LCAT) and ester transfer proteincholesterol (CETP) in medical students. Rev. Colomb. Cardiol. [online]. 2015, vol.22, n.6, pp.277-284. ISSN 0120-5633. https://doi.org/10.1016/j.rccar.2015.04.007.
Objective: To evaluate exercise effect on HDL subpopulations, lecithin-cholesterol acyltransferase enzyme and ester transfer protein cholesterol levels in medical students. Method: Population was divided voluntarily into 2 groups, exercise and no exercise. Waist circumference and body mass index were measured; subfractions HDL2 and HDL3 by ion precipitation and LCAT and CETP enzymes Enzyme-Linked Immuno-Sorbent Assay (ELISA). Results: Lipidrisk profile increased in both groups; HDL, HDL2 and HDL3 decreased in both groups, but only the HDL2 decreased significantly in students who exercised. LCAT and CETP remained without significant changes, however, in the exercise group, there was statistically significant decrease in HDL2 and LCAT in women. Conclusions: This study shows that exercise does alter some variables such as waist circumference, body mass index and HDL3. These changes are dependent on gender, but despite the intervention of 3 months with an exercise program, it fails reducing lipid risk factors in this medical student populations, given their environment, which complicates their metabolic response to exercise.
