Newborn brains boosted by exercise during pregnancy

A study of 60 healthy pregnant women aged 20–35 years, recruited in the first trimester, showed those engaging in regular cardio-vascular exercise had babies with more mature brains at 8–12 days postpartum compared to those assigned to a sedentary control group.

Electroencephalography was used to record the babies’ response to repeated and novel sounds, the researchers said in a statement.

They presented the results at the Society for Neurosciences’ Neuroscience 2013 congress in San Diego, US, last week.
