Study: Exercise during Pregnancy Benefits Babies and Moms

"For the study, which was presented on Sunday at the Experimental Biology 2011 meeting in Washington, researchers from the Kansas City University of Medicine and Biosciences revisited a group of 61 healthy women, ages 20 to 35, who'd been part of a pilot study of exercise, pregnancy and fetal heart health. About half of the women had exercised regularly during their pregnancies, jogging, power-walking or otherwise working out at a moderate pace at least three times a week. Some also had lifted light weights or practiced yoga. But their primary activity had been aerobic. The other half of the mothers-to-be "were normally active but did not engage in formal exercise," said Linda E. May, an exercise physiologist who led the study."
