  Purpose

The effects of physical exercise on pregnancy remain to be elucidated. A randomized controlled trial will be conducted to study the impact of exercise on maternal and perinatal outcomes. Our hypothesis is that physical exercise reduces preeclampsia incidence and improves birthweight when started early in pregnancy, with no impact on pregnancy duration, Apgar scores and neonatal complications.


Condition Intervention
Preeclampsia
Gestational Diabetes
 Other: Physical exercise

Primary Outcome Measures:
  • Maternal outcome: preterm labor, weight gain, preeclampsia, gestational diabetes Perinatal outcome: birthweight, Apgar scores, body composition, admission at neonatal intensive care unit [ Time Frame: nine months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Doppler flow velocimetry indexes: pulsatility, resistance and A/B relation (uterine arteries, fetal middle cerebral artery and umbilical arteries) [ Time Frame: 9 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 188
Study Start Date: April 2008

Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 2
Pregnant women starting to practice physical exercise at 13 weeks(Walking moderate activity)
 Other: Physical exercise
Walking 3 times a week during 1 hours (moderate activity)
Other Name: physical activity; physical exercise; walking
Experimental: 3

Detailed Description:

The study will include low risk pregnant women randomized to practice physical exercise beginning at 13 weeks, 20 weeks or no exercise group.

The objectives are:

  1. To describe and compare biological and obstetrical variables.
  2. To study doppler flow velocimetry indexes.
  3. To determine the association between physical exercise and maternal complications: preeclampsia, preterm labor, gestational diabetes and weight gain in pregnancy.
  4. To determine the association between physical exercise and perinatal outcomes: Apgar scores, birthweight, admission at intensive neonatal care unit, body composition and neonatal complications.
