| Purpose: The aim of the present study was to examine the influence of moderate physical exercise throughout pregnancy on the duration of labor stages. Design: Randomized controlled trial. Setting: Hospital Puerta de Hierro and Hospital Severo Ochoa in Madrid, Spain. Subjects: We examined 166 pregnant women (31.6 ± 3.8 years), and all had uncomplicated and singleton gestation; 83 were allocated to the exercise group [EG] and 83 to the control group [CG]. Intervention: Women from the EG participated in a physical conditioning program throughout pregnancy, which included 55 to 60 minute sessions, 3 days per week. Measures: Pregnancy outcomes: duration of labor stages, gestational age, weight gain, type of delivery, birth weight, birth size, head circumference, Apgar Score, pH of umbilical cord. Analysis: Student?s unpaired t-tests and ?2 tests were used; p values of < .05 indicated statistical significance. Cohen?s d was used to determine the effect size. Results: Significant differences were found in the duration of the first stage of labor (EG=389.6 ± 347.64 min vs. CG= 515.72 ± 353.36 min, p= .02, effect size Cohen¿s d= .36). The second and third stages did not differ between the study groups. Conclusion: A physical exercise program during pregnancy is associated with a shorter first stage of labor. These results may have important relevance to public health. | |
