%X In a non-randomized controlled trial, 133 previously sedentary pregnant women participated in multiple regular sessions of water aerobics in a heated swimming pool. Cardiotocography was performed for 20 minutes before and just after the oriented exercise. Cardiotocography patterns were analyzed pre- and post-exercise according to gestational age groups (24-27, 28-31, 32-35 and 36-40 weeks). Student's t and Wilcoxon, and McNemar tests were used, respectively, to analyze numerical and categorical variables.No significant variations were found between pre- and post-exercise values of fetal heart rate (FHR), number of fetal body movements (FM) or accelerations (A), FM/A ratio or the presence of decelerations. Variability in FHR was significantly higher following exercise only in pregnancies of 24-27 weeks.Moderate physical activity in water was not associated with any significant alterations in fetal cardiotocography patterns, which suggests no adverse effect on the fetus.In the past, the practice of physical activity by pregnant women has always been surrounded by uncertainties and was considered a taboo. Sedentary approaches were encouraged and women were counseled to stay off their feet as much as possible. In addition, the fear that women could acquire genital infections from immersion in water caused health professionals to discourage this activity [1]. Currently, there is an almost general recognition among health professionals that moderate exercise offers no risks to pregnant women as long as there are no obstetrical complications or preexisting conditions, such as vaginal bleeding, arterial hypertension or cervical incompetence [2].In 1985, the American College of Obstetricians and Gynecologists (ACOG) issued the opinion that exercise during low-risk pregnancy is safe for the mother and fetus when maternal heart rate does not exceed 140 beats per minute for more than 15 minutes [3]. Recent guidelines issued by the ACOG recommend caution and medical supervision
