Exercise during pregnancy appears to protect offspring from age-related health risks. Researchers examined markers of oxidative stress, inflammation, and insulin sensitivity in mice that were born to mothers that either exercised or didn’t exercise during pregnancy. They found that the offspring of mothers that exercised had better stress resistance and improved insulin sensitivity, even into adulthood, than the mice born to sedentary mothers. The researchers write, “Our findings highlight pregnancy as a sensitive period when positive lifestyle interventions could have significant and long-lasting beneficial effects on offspring metabolism and disease risk.” American Physiological Society’s, November 2016
