Lipoprotein(a) and body mass in mice which were submitted to Hypercholesterolemia and strength and aerobic physical trainings

Abstract

Introduction: The objective of the study was to verify the effects provoked by strength and aerobic exercises on the lipoproteic plasmatic concentrations of lipoprotein(a) [Lp(a)] and body mass in mice which were submitted to a hypercholesterolemic diet. Materials and Methods: 43 8-week-old male mice from Wistar family and weight between 230g and 250g were used in the sample. They were divided into six groups: strength training with hypercholesterolemic diet (FD, n=7); aerobic training with hypercholesterolemic diet (AD, n=6); strength training with conventional diet (FN, n=6); aerobic training with conventional diet (AN, n=9); hypercholesterolemic diet (CD, n=7); and conventional diet (CN, n=8). The strength and the aerobic exercises were accomplished during 12 weeks. At the end of the experimental period, the plasmatic concentrations of Lp(a) were dosed. Results: No differences have been verifi ed in the plasmatic concentrations of Lp(a) with the different types of physical training. The prolonged treatments with hypercholesterolemic diet did not alter the levels of Lp(a). Discussion: The strength and aerobic trainings in animals with hypercholesterolemic and conventional diet did not provoke changes in the plasmatic concentrations of Lp(a).
