| Introduction Obstetricians lack sufficient information for providing constructive guidance for patients who want to be physically active during their pregnancies. One frequently asked and important question regards the possibility that physical activity, especially during the second part of pregnancy, might affect gestational outcomes, such as type of delivery. We examined the effect of light exercise training performed throughout the second and third trimester of pregnancy on the type of delivery, as well as on the dilation, expulsion and childbirth time. Methods 160 sedentary women were randomly assigned to either a light intensity resistance and toning exercise training group (n=80) or a control group (n=80). Several maternal and newborn¿s characteristics, were recorded including the type of delivery (normal, instrumental, or cesarean) and dilation, expulsion and childbirth time. Results The percentage of women having normal, instrumental or cesarean delivery was similar for both the training (70.8%, 13.9% and 15.3% respectively) and control groups (71.4%, 12.9% and 15.7% respectively). The expulsion, mean dilation and childbirth time did not differ between groups. Discussion Certain scientific evidence has demonstrated that physical exercise during pregnancy does not have adverse effects (Barakat et al, 2008, 2009). In that sense, our results showing no differences in the type of delivery between both groups are in apparent disagreement with previous data from prospective (Bungun et al, 2000. Clapp, 2008) or training studies, which suggests that regular exercise performed over the course of pregnancy is associated with increased incidence of vaginal delivery (Hall & Kaufmann, 1987) . Comparisons between studies are difficult to make owing to differences in several variables that can affect type of delivery such as age, body mass index, gestational weight gain age, previous parity history, smoking habits, alcohol intake, number of hours standing or epidural anesthesia. In conclusion in we found that light intensity resistance and toning exercise training performed over the second and third trimester of pregnancy does not affect the type of delivery. | |
