The Claim
Weekly exercise duration during pregnancy is independently associated with increased infant birthweight in women at moderate risk of hypertensive disorders, after adjusting for gestational age.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Pregnant women who exercise more each week tend to have babies with higher birthweights, even when you account for how long the pregnancy lasted. It’s not just about going longer—it seems like exercise itself might help the baby grow bigger.
See the scientific wording
Weekly exercise duration during pregnancy is independently associated with increased infant birthweight in women at moderate risk of hypertensive disorders, even after accounting for gestational age, suggesting that the length of time spent exercising each week may directly influence fetal growth beyond simply prolonging pregnancy.
What the research says
1 studyThis study found that pregnant women who exercised more each week had babies with higher birthweights, even when the babies weren’t born later — meaning exercise itself helped the baby grow bigger, not just make the pregnancy longer.
