This study aims to determine the effect of a physical exercise program on microcirculation and maternal and perinatal outcomes in obese women. A randomized clinical trial will be performed at IMIP with obese pregnant women assisted at the Instituto de Medicina Integral Professor Fernando Figueira (IMIP) prenatal service.
Obesity in pregnancy is an important risk factor for adverse perinatal outcomes. Obesity leads to oxidative stress and vascular damage including microcirculation inflammation. Physical activity prevents cellular damage and provide a protective effect to the health of the mother and fetus. Although physical activity has been recommended for obese pregnant women, studies assessing the effects on the microcirculation of these women are scarce. This study aims to determine the effect of a physical exercise program on microcirculation and maternal and perinatal outcomes in obese women. A randomized clinical trial will be performed at IMIP with obese pregnant women assisted at the IMIP prenatal service. The intervention group will be submitted to an exercise program consisting of daily post prandial, 10' after breakfast, lunch and dinner. The control group will follow the routine prenatal IMIP. All pregnant women will be evaluated by a questionnaire to assess physical activity. Microcirculation function will be evaluated by a Laser-doppler flowmetry at baseline and eight weeks after intervention. All pregnant women will be followed until the delivery and immediate postpartum period to check their perinatal outcomes. All pregnant women will be advised to use a pedometer to record their daily steps. The study meets the recommendations of the National Health Council. This project was submitted and approved from the Ethics Committee for Research involving human subjets of IMIP. All participants will be duly informed about the aims of the study and will be included after signing the Informed Consent Form.

| Effects on microcirculation | Microcirculation will be assessed using the Laser-doppler flowmetry manufacturers software (Moor Instruments, UK) and expressed in perfusion units (PU). The parameters that will be used to evaluate the microcirculation (microvascular function) are: resting skin blood flux (RF), maximum skin blood flux (MF) at peak PORH, the ratio of maximum level and flow at rest (MF/RF) and the area of hyperemia (AH) which is the graphical area under the curve formed during PORH. | change from baseline microcirculation after 8 weeks |
