The Claim

Among pregnant recreational athletes, structured exercise during resistance training leads to a greater increase in placental vascular flow index (VFI) compared to the overall cohort, suggesting that regular physical conditioning may enhance placental perfusion response to acute resistance loads.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Pregnant women who regularly work out and do strength training may see better blood flow to the placenta during their workouts compared to other pregnant women, which could help the baby get more oxygen and nutrients.

See the scientific wording

Among pregnant recreational athletes, those who engaged in structured exercise exhibited a greater increase in placental vascular flow index (VFI) during resistance training (from 2.031 to 2.203, p=0.01) compared to the overall cohort, suggesting that regular physical conditioning may enhance placental perfusion response to acute resistance loads.

What the research says

  1. Study: Resistance Training Does Not Decrease Placental Blood Flow During Valsalva Maneuver: A Novel Use of 3D Doppler Power Flow Ultrasonography

    Pregnant women who regularly exercise showed better blood flow to the placenta during weightlifting than those who don’t, meaning their bodies may be better at feeding the baby during workouts.
