摘要
ObjectivesTo study effects of regular physical exercise in pregnancy on duration of the active phase of labor and the proportions of women with prolonged active second stage. DesignA two-armed, two-center randomized controlled trial. SettingSt. Olavs Hospital, Trondheim University Hospital and Stavanger University Hospital. PopulationA total of 855 women were randomized to intervention or control groups. MethodsThe intervention was a 12-week exercise program, including aerobic and strengthening exercises, conducted between the 20th and 36thweek of gestation. One weekly group session was led by physiotherapists and home exercises were encouraged twice a week. Controls received standard antenatal care. Main outcome measuresThe duration of active phase of labor and number of prolonged second stage deliveries (active pushing > 60min). We also studied labor outcomes. Supplementary analyses were done in a subgroup of nulliparous women with a singleton cephalic fetus and spontaneous start of term delivery. ResultsDuration of labor was similar in the two groups, and there were no differences in labor outcomes. In a subgroup analysis the duration of active second stage labor was shorter in the control group (p=0.01). ConclusionsRegular physical exercise during pregnancy did not influence duration of the active phase of labor or the proportion of women with prolonged active second stage.
