Pregnancy workout trial aims for healthier moms and babies
NCT ID NCT07264231
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a structured exercise program during the second and third trimesters of pregnancy can improve the mother's fitness, blood vessel health, and weight gain, as well as the baby's health at birth. Sixty-four first-time pregnant women will participate. The goal is to see if simple lifestyle changes like exercise can reduce pregnancy complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- structured exercise program
- What this could lead to
- If it works, this could show that regular exercise during pregnancy improves mother's fitness and may reduce pregnancy complications.
- What could go wrong
- This is a small, early-stage trial with only 64 participants, so results may not apply to all pregnant women. Exercise benefits are already known, so the impact may be modest.
