Effects of physical exercise on the lipid and inflammatory profile of young women using combined oral contraceptives: protocol of a cross-sectional study

Abstract

INTRODUCTION: The use of combined oral contraceptives (COC) is a risk factor for atherosclerotic disease because it compromises the lipid and inflammatory profile, and physical exercise can minimize these conditions. OBJECTIVE: To test the hypothesis that high intensity interval physical exercise promotes changes in the lipid and inflammatory profile of women who are irregularly active using COC. METHODS: Protocol of a cross-sectional study with women of 20 and 30 years, irregularly active, using COC for at least 6 months. A physicalclinical assessment (AFC) was performed on the participants with anthropometric measurements, VO2max. analysis and analysis of the lipid and inflammatory profile. Afterwards, the participants were divided into 2 groups: the initial intervention group (GII) that started practicing high intensity interval exercises for 2 months, and the posterior intervention group (GIP), which remained irregularly active for the same period. Then the GII and GIP would alternate their conditions for another 2 months, totaling 4 months of follow-up and 3 AFC, performed at the beginning, after 2 months and at the end of the study. The information collected was divided into 3 moments: Initial moment (MI), post-exercise moment (MPE) and post-inactivity (MPI).
