Effects in Type of Birth of Physical Exercise During Pregnancy
Abstract:
Objectives:[The goal is] to confirm if physical activity of medium intensity performed during gestation can influence the way of delivery, and observe the adherence to exercise among pregnant women with different education levels. Methods: Held at the Center for Breastfeeding Incentive in the city of São Sebastião, State of São Paulo (Brazil), between April 7, 2008 and April 14, 2009, the prospective study involved 66 primigravid women, who were divided into two groups: the exercise group (GE) that exercised regularly during pregnancy, and the other control group (GC) that did not exercise regularly during same period. The significance level adopted in this study was five per cent (p = 0.05).

説明
The inclusion criteria:
- nulliparae,
- sedentary women,
- ages between 18 and 30,
- gestation age superior to 18 weeks without clinical or obstetrical complications
Exclusion Criteria:
The volunteers in the GE couldn't have a gestation age superior to 20 weeks, had to participate on regular physical activity twice a week, and have a total frequency of at least 20 sessions. The EG pregnant women with frequency inferior to 20 sessions were discarded from the study.
The volunteers in the CG couldn't have performed regular physical activity during pregnancy. In both groups, the participants hadn't performed regular physical activity in the year prior to the pregnancy.
However, 31 women were discarded during the research: three for miscarriage, being two from the GE and one from the GC; one from the GE for anemia; one from the GC for pre-eclampsia; two for loss of contact after birth, being one from each group; 11 from the GE for not reaching the minimum frequency; seven claimed personal reasons for leaving the research, being five from the GC and two from the GE; and six participants abandoned the study.
