Resumen de Bouncing babies get a boost for their brains
A mothers exercise could give her child a head start. Babies born to women who exercised during pregnancy have more mature brains, suggesting that staying active may be good for all concerned. Earlier work hinted that such children had better communication skills when they were five and scored higher on intelligence tests. However, these studies relied on women remembering how much exercise they had done while pregnant. To investigate, Elise Labonte-LeMoyne at the University of Montreal in Canada and her colleagues randomly assigned 29 pregnant women to one of two groups. Starting when they were around 12 weeks pregnant, one group did at least 20 minutes of moderate exercise such as briskwalking, swimming or cycling three times a week; the other group stopped exercising completely.
