Study summary

Evaluate the effects of the practice of maternal physical exercise on the term of pregnancy as a method to enhance spontaneous labor.

Read the detailed description

At 38 weeks low-risk pregnant women, with singleton cephalic fetus and without previous cesarean delivery, were randomized into 2 groups: a control group without maternal physical exercise practice and a study group with 30 minutes of walking, 3 times a week at 4 Km/h. Induction of labor was performed at 41 weeks

The record gives a start of May 2015, a primary completion of Jan 2016 and a completion of Jan 2016. It does not say whether these dates are actual or estimated.

How these figures are worked out, and which studies are left out of them.

What these dates mean

Start.: When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.: When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.: When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.: Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.

No changes since tracking began. The registry record was last updated on Oct 12, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
