Physical exercise during pregnancy. A risk for the newborn?

We present an investigation work that relates the physical exercise developed during the second and third pregnancy trimester with the general health status of new born. A case-control design was used, 142 pregnant women were enrolled into this investigation, 72 women for a case group and 70 women for a control group. Exercise program consisted on 3 sessions weekly of 35 minutes of aerobic exercise of heart rate no more than 140 lat/min, during second a third trimester. Women were evaluated for the confounding variables (maternal age, parity, prior preterm delivery, smoking, occupational activities). The realization of 35 minutes of aerobic, moderate exercise during second a third trimester of pregnancy does not influence on general health status of new born.
